Fast-Acting Clarifier: SilaFine quickly creates crystal-clear beer by removing yeast and haze-forming particles, delivering high-quality results in as little as 24 hours. Preserves Beer Foam: Unlike other fining agents, SilaFine targets only haze-forming particles and yeast, leaving foam-active proteins intact, ensuring a great beer head in every pour. Versatile Application: Effective both in finished beer and during the whirlpool stage, SilaFine offers flexibility for brewers, with different dosing options for quicker, compact sedimentation. Vegan-Friendly & Purity Compliant: Made from pure, natural silica sol, SilaFine is vegan-friendly and complies with the Reinheitsgebot German beer purity law. SilaFine is an easy-to-use, vegan friendly fining agent that quickly creates crystal clear beer by removing yeast and haze-forming particles. This highly effective clarifier will eliminate or greatly reduce the need for filtration without affecting flavor. SilaFine is a unique, negatively charged silica sol fining agent that binds with positively charged haze active proteins and polyphenols to create an electrostatic net that also drags down yeast cells. SilaFine does not target foam active head forming proteins, so the beer foam in glass is unaffected. Use: Add 10ml or 1 tbsp per 5 gallons of finished beer. Gently rouse the beer to fully disperse the clarifier. SilaFine will work to drop out yeast at fermentation temperatures, but for full effectiveness on haze-inducing particles, we recommend adding it to beer that has been chilled below 39°F. If the beer has not cleared after 24 hours, a second dose can be added. SilaFine should be stored cool, but do not freeze. Unitanks & Brites: If you are using a brite tank, SilaFine is best added to the beer stream inline when pumping from fermenter to brite. If you are using a Unitank and no brite tank, add to the top of the Unitank while rousing with CO2 for 5-10 minutes from the bottom. Or you can use a pump loop to recirculate the beer in a Unitank, instead of rousing with CO2. If added at ideal temperatures below 39°F, and well dispersed into the tank, clarification can take as little 8-12 hours. Otherwise clarification may take up to 48 hours. We advise against using more than the recommended amount, as overdosing can actually increase haze temporarily and cause a longer settling period.  Dosage Rate in Whirlpool: SilaFine can also be used in the whirlpool at a rate of 0.5-1ml per gallon to achieve a quicker and more compact sedimentation in the kettle.   Additional Notes: SilaFine is based on a special selection of commercial grade amorphous silicon dioxide, also known as silica sol, at a concentration of 30%. Silica sol is known by a few names in brewing including colloidal silica, acidified silicates, silicon dioxide, and silicic acid. Unlike some other silica sols, SilaFine is not treated with aluminum oxide. SilaFine is a pure mineral and complies with Reinheitsgebot German beer purity law. Do not freeze. Store in a cool, dry place away from direct sunlight and heat.   The recommended shelf life is 12 months from the date the package is opened.   Allergen Free GMO Free

100% Natural Yeast Nutrient: FermFed DAP Free is a fully organic nutrient blend, derived from yeast autolysis, rich in amino acids, vitamins, and essential minerals like zinc and magnesium, ensuring optimal yeast health for successful fermentations. Organically Derived Nitrogen: Unlike traditional nutrient formulations containing inorganic diammonium phosphate (DAP), FermFed DAP Free provides organic nitrogen, reducing the risk of off-flavors and promoting a cleaner fermentation. Ideal for Hard Seltzer and Beer Fermentations: FermFed DAP Free is the preferred nutrient for hard seltzer fermentations and works well in beer, promoting healthy yeast activity even in high alcohol fermentations (up to 10% ABV). Comprehensive Yeast Protection: The blend includes sterols for alcohol and temperature resistance, mannoproteins to retain aromas, and essential B-vitamins, zinc, and magnesium to support yeast performance and prevent stuck fermentations. The ideal nutrient blend for beer fermentations, FermFed DAP Free is a 100% natural formulation derived from the autolysis of very specific yeast strains naturally high in free amino acids, sterols, mannoproteins, zinc, magnesium, and niacin, along with vitamins B1, B2, B5, B6, and B12 for a complete yeast health regimen.  As the name suggests, this unique formulation does not contain the traditional inorganic diammonium phosphate, but does provide organically derived nitrogen. Help your yeast start fermentation on the right foot with FermFed DAP Free by CellarScience®. FermFed DAP Free vs Regular FermFed Regular FermFed contains DAP, diammonium phosphate, which is an inorganic nitrogen source. If you know your fermentation needs nitrogen, typically in non-malt fermentations such as wine, DAP is more readily processed by the yeast than the organic nitrogen found in FermFed DAP free. However, if the DAP is not processed by the yeast, and left behind in the beer, there is a higher risk of off flavors. At the suggested usage rates, FermFed DAP Free provides 30ppm of organic FAN, Free Available Nitrogen, while FermFed provides 38ppm of inorganic FAN.  For Use in Hard Seltzer We have found that FermFed DAP Free is the preferred nutrient mix for Seltzer fermentations, with the organic nitrogen component being more than enough nitrogen to support a healthy fermentation. For high alcohol fermentations closer to 10% ABV, multiple additions of FermFed DAP free are required.   How Much Do I Add and When? The general recommendation for most beer fermentations is to add 1.5 grams per gallon. Mix the nutrient in a small slurry of water and add to the fermentation prior to pitching yeast.   How it Works The different components of FermFed DAP Free work in different ways to feed and protect your yeast.   The complex and organic nitrogen in FermFed DAP Free helps eliminate excessive yeast growth in the initial phases helping to reduce fermentation heat spikes at the start of fermentation.  Included sterols make the yeast membrane more resistant to alcohol and to high temperatures.  The collection of B-vitamins along with zinc and magnesium are essential for enzymatic activity, alcohol tolerance, and yeast health.  Mannoproteins help avoid the aromatic stripping during the fermentation by binding esters and terpenes and not allowing them to be driven off by CO2.  The included yeast hull components act as receptors to bind up fatty acids that can accumulate and cause stuck fermentations. For a full yeast nutritional plan, use FermStart when rehydrating yeast.

Prevents Boil-Overs: One drop per gallon eliminates messy boil-overs, making your brewing process cleaner and safer, saving time on cleanup. Increases Fermenter Capacity: Reduces Krausen foam during fermentation, allowing more beer volume and minimizing the risk of messy blowouts. Improves Head Retention: Enhances head formation in finished beer by preserving foam-forming proteins that would otherwise be lost during fermentation. Food-Grade and Easy to Use: Made from food-grade silicone, Foam Axe safely breaks up foam with just a few drops, settling out before bottling or kegging. Stop boil overs in the kettle and limit foaming in your fermenter with CellarScience Foam Axe. This uniquely formulated anti-foaming agent reduces surface tension so bubbles are Axed before they can form. Foam Axe actually increases head formation in the finished beer by retaining foam forming proteins that would have normally blown off during fermentation. Use it in your boil kettle to prevent boil-overs for a cleaner, safer process. Then add Foam Axe to your fermenter to reduce Krausen, save beer, and increase the volume capacity of your fermenter. In the Kettle: Nobody likes a boil over as they are messy and take considerable time to clean up. Save time, beer, your burner or stove, (and possibly your relationship) by adding 1 drop per gallon of Foam Axe into your kettle and eliminate boil overs from your brew day!     In the Fermenter: Foam Axe works like magic in the fermenter. Just 2 drops per gallon at the start of fermentation will keep your airlock and blowoff clean. We recommend adding before pitching yeast and rousing well while you aerate your wort. Many commercial breweries use Foam Axe to increase fermenter capacity and homebrewers can do the same. Additional Notes: Foam Axe is made from food-grade silicone and works by breaking up foam particles and dispersing surface tension. Foam Axe settles out of beer prior to bottling or kegging. Store cool and in an environment below 90°F. Do not freeze. The recommended shelf life is 6 months from the date the package is opened.

Enhanced Yeast Performance: FermStart provides a concentrated blend of micronutrients, including amino acids, sterols, and vitamins, which helps yeast transition quickly from dormant to active, ensuring a healthy and robust fermentation process. Faster Fermentation Start: By supplying readily assimilable nutrients, FermStart allows yeast to skip energy-consuming steps, promoting faster yeast cell multiplication and out-competing wild yeast, ensuring your selected yeast dominates the fermentation. Strong Cell Membrane Support: Sterols in FermStart help yeast cells maintain membrane elasticity, enhancing their ability to survive and perform well under tough fermentation conditions, ensuring consistent fermentation results. Antioxidant Protection: The inclusion of glutathione, a powerful antioxidant, helps protect yeast cells from oxidative damage during rehydration, improving yeast health and promoting a more stable and efficient fermentation process. If you’re rehydrating beer yeast, it’s quick and easy to ensure a perfect ferment by adding FermStart by CellarScience®.  FermStart is a concentrated micronutrient blend that helps yeast during the critical phase in which they transition from dried and dormant back into healthy and active.  FermStart is added to your rehydration water so that your yeast absorbs the nutrients as they absorb the water.  When gravities exceed 15° Plato or 1.060 starting gravity, it is recommended to rehydrate your yeast.  To ensure a perfect ferment that reaches its full flavor potential, rehydrate your yeast with FermStart. How Much? FermStart is a super concentrated formula, which is very convenient when you are rehydrating large amounts of yeast.  Use 1 gram of Fermstart for every 4 grams of yeast.  We offer some suggested ranges for the amount of water to use below.  Examples: 12g yeast - Add 3g FermStart to roughly 50ml of water 500g yeast - Add 125g FermStart to roughly 1500 ml of water The Science of How it Works FermStart is rich in readily assimilable amino acids, sterols, vitamins, and natural glutathione.  Readily assimilable means that the size of the molecules present in FermStart are extremely small and easily absorbed by the yeast cell. This is obtained by centrifuge and allows FermStart to be extremely concentrated and not contain filler. The availability of readily assimilable amino acids allows the yeast cell to skip the step in which amino acids would be synthesized within the cell. This saved energy is instead directed into multiplication. Faster yeast cell multiplication means a faster start allowing your yeast to out-compete wild yeast. Wild yeast have unknown flavors and fermentation behavior so it is important to give the yeast you selected the best chance to dominate the fermentation. Sterols help the cell membrane regain and maintain elasticity helping to ensure a perfect start and continued performance throughout the fermentation. The strong cell membrane helps ensure that the yeast can survive and complete alcoholic fermentation under tough conditions. Glutathione is a very special natural antioxidant and detoxifier made up of three amino acids cysteine, glutamate, and glycine.  It is extremely important for maintaining intracellular health by preventing damage to cellular components during the very oxidative process of rehydration.

Comprehensive Yeast Nutrition: FermFed provides a complex blend of essential nutrients like diammonium phosphate (DAP), thiamin, amino acids, sterols, and vitamins (B2, B5, B6, B12), supporting yeast health and optimizing fermentation. Prevents Off-Flavors: FermFed’s nitrogen content helps prevent the production of undesirable compounds like hydrogen sulfide (rotten eggs), ensuring cleaner and more desirable flavors during fermentation. Enhanced Fermentation Performance: Ingredients such as sterols and mannoproteins promote yeast cell strength and improve the retention of aromatic compounds, helping yeast finish fermentation smoothly while enhancing flavor retention. Versatile Application: Ideal for wine and non-malt fermentations with known nitrogen deficiencies, FermFed is also available in a DAP-free version suitable for malt-based fermentations with unknown nitrogen levels. FermFed is a complex nutrient blend of diammonium phosphate, thiamin, amino acids, sterols, pantothenic acid, mannoproteins, protective microelements derived from yeast hulls, and vitamins B2, B5, B6, & B12.  FermFed also contains the organic and inorganic nitrogen (DAP) that yeast need. Help your yeast reach the end of fermentation safely while producing amazing flavors with FermFed by CellarScience®. FermFed is a great choice for wine and other non-malt based fermenations where there is a known nitrogen deficiency. For beer or other fermentations where nitrogen levels are unknown we recommend FermFed DAP Free.  The organic nitrogen supplied in FermFed DAP Free is sufficient for all malt fermentations and poses less potential issues if not consumed by the yeast. Read more about FermFed DAP Free. How Much Do I Add and When? For most beer fermentations add 1 gram per gallon. Mix the nutrient in a small slurry of water and add to the wort just prior to pitching yeast. How it Works The different components of FermFed work in different ways to feed and protect your yeast.  When yeast do not have enough nitrogen, they are more likely to produce hydrogen sulfide (rotten eggs). FermFed helps to eliminate this problem by providing enough nitrogen for most situations.    As yeast divide and multiply they get weaker and might not be able to properly finish fermentation as the alcohol content rises. Feeding them sterols help cells maintain membrane fluidity so that the yeast can properly function.   Mannoprotein molecules bind esters and terpenes and work as an anchor to keep them in solution so they are not driven off by CO2 during fermentation.  Pantothenic acid is added to help reduce the production of hydrogen sulfide.   Thiamine is important for yeast metabolism.  Vitamins B2, B5, B6, & B12 are important for general yeast health. For a full yeast nutritional plan, use FermStart when rehydrating yeast.

This enzymatic solution targets and breaks down haze-inducing proteins so they cannot later bind with tannins to create beer haze. Clearzyme by CellarScience specifically targets haze-active proteins, so it has no negative effect on flavor, aroma, or head retention. One of the huge benefits of Clearzyme is that it removes the need to cold crash, saving time and energy. Use: Add 1/4 tsp per 5 gallons at the start of fermentation. Works best at a temperature range between 50-68°F and pH of 4-6. Additional Notes: Clearzyme is a protease, or proteolytic, enzyme that partially or totally hydrolyzes peptide bonds in protein. The resulting protein fractions are then too small to bond with the polyphenols in hops. It also breaks down the gluten protein that causes allergic reactions. Beers made with barley and wheat that have had Clearzyme added typically show gluten levels below 20ppm. Store at temperatures under 70°F. Immediately recap bottle after each use. The recommended shelf life is 12 months from the date the package is opened.

Improves Mash Flow and Efficiency: Glucabuster breaks down glucans, arabinoxylan, and cellulose to prevent stuck mashes and slow runoff, ensuring smoother lautering and improved yield. Enhances Downstream Filtering: By breaking down polysaccharides, Glucabuster helps simplify filtering in later brewing stages, ensuring cleaner and faster processes. Effective Across a Wide Range of Temperatures and pH Levels: Works efficiently within a temperature range of 120-185°F and an ideal pH range of 4.7-7.0, making it versatile for various brewing conditions. Highly Concentrated and Easy to Use: With just 1/4 tsp needed per 5-gallon batch, Glucabuster offers a highly concentrated solution for improving mash flow and overall brewing efficiency. Glucabuster by CellarScience improves lautering and yield while making potential downstream filtering easier. Highly concentrated ß-glucanase breaks down glucans that can lead to stuck mashes and slow runoff. Xylanase and Cellulase break down the polysaccharide chains of arabinoxylan and cellulose. Together, all three enzymes help keep today’s challenging mashes flowing right. Use: Add 1/4 tsp per 5-gallon batch at mash-in. Glucabuster works in a range of 120-185°F and ideally at a pH range of 4.7-7.0. Additional Notes: Endosperm cell walls are made up of non-starch polysaccharides, of which, in barley, β-glucans account for 75% with arabinoxylan (pentosan) and cellulose accounting for most of the rest. In wheat, the arabinoxylan content is higher. Glucabuster is composed of the cell wall hydrolases β-glucanase, xylanase, and cellulase, which break down the β-14 bonds in these polysaccharides. These enzymes can be equally important to their more famous starch degradation enzymes, α-Amylase and β-Amylase.  Glucanase, xylanase, and cellulase are naturally found in malt but decrease during the kilning stage of malting. Depending on your recipe, adding these enzymes is important to assist with lautering and later with filtering. Refrigeration is recommended, but store at least below 70°F. The recommended shelf life is 12 months from the date the package is opened.

Easily added to mash water to reduce oxidation in finished beer Scavenges oxygen in mash water Reduces Lipoxygenase (Lox) activity in malt which reduces trans-2-nonenal stale/cardboard flavors in beer Reduces hot side aeration Results in beer with fresher flavor and longer shelf life Oxblox 3D is a specially formulated blend of gallotannins, ascorbic acid, and metabisulphite that is added to your strike water right before mash-in. It dissolves easily and is extremely useful to reduce oxidation during the mashing process. Through multiple actions, it reduces dissolved oxygen levels and helps inhibit the lipoxygenase enzyme found in malt that is infamous for causing downstream wet paper / cardboard flavors attributed by the (E)-2-nonenal compound. Oxblox 3D has minimal impact on pH but may lower pH levels by 0.2-0.4 in both the mash and the finished beer. You may not always notice stale flavor compounds in beer when present, especially at low levels. But when removed, the beer can smell and taste fresher. Beer treated with Oxblox also has an enhanced shelf life, staying fresher for longer. Overall, Oxblox 3D is a low cost, easy-to-use addition to help you brew better tasting beer that lasts longer in keg, can, or bottle. Use: Mix 0.2 to 0.4 g per gal (0.05 to 0.1 g per liter) into your strike water directly before dough-in. We recommend starting with a dosage of 0.3 g per gallon of strike water (0.08 g per liter of strike water) and adjust as desired in future batches.

Unique amino acid blend activates Ehrlich pathway causing beer and wine yeast to produce tropical flavors Contributes complexity to beer styles like Hazys where tropical flavors are desired. Pairs perfectly with CellarScience HAZY Yeast Contributes tropical complexity to Sauvignon Blanc and Viognier wines when used in conjunction with CellarScience CITRUS Wine Yeast Enhance tropical flavors in your beer or wine with CellarScience Tropic Thunder. By changing the amino acid mix you feed your yeast you can influence the final flavors yeast produce. To understand why, we have to first explain the Ehrlich pathway which was discovered over 100 years ago by German Biochemist Felix Ehrlich. Yeast absorbs and breaks down a specific set of amino acids very slowly over the course of fermentation. The yeast cells incorporate the amino group into their cell structure, leaving an alpha-keto acid. This acid is turned into fusel alcohol by the yeast and then returned back out into the wort. This production of fusel alcohols via the breakdown of specific amino acids is called the Ehrlich Pathway. For Beer Fusel alcohol may scare you as a brewer... we get it, you are trained to avoid these! But certain fusel alcohols actually have a really positive effect on the final beer flavor. The idea behind CellarScience Tropic Thunder is we have selected specific amino acids that when fed to your yeast will result in the production of a small amount of fusel alcohols that contribute to the tropical flavors of mango, pineapple, and coconut. Tropic Thunder nutrient is often used to help create complexity in hazy IPA, but feel free to use it in any style where tropical flavors would be welcome—you are only limited by your imagination! When used in beer, Tropic Thunder can replace your typical yeast nutrient as it is itself an organic, DAP-free nutrient. If you typically use a complex nutrient that includes DAP, you can continue to add it separately as normal. For Wine Tropic Thunder is perfect for Sauvignon Blanc, Viognier and other select styles where tropical fruit flavors are part of your vision. In addition to selecting a thiol releasing yeast strain such as CellarScience CITRUS, Tropic Thunder can help bring complimentary tropical fusel flavors via the Ehrlich pathway. As a part of the overall mix, along with thiols and terpenes, the complexity of Sauvignon Blanc or Viognier is enhanced. Tropic Thunder can also be used in select Chardonnays or any white wines where tropical mango and pineapple flavors are desired. When added at the rate of 0.6 to 2 grams per gallon, Tropic Thunder contributes 3 to 12 ppm of YAN. When using CellarScience FermFed or FermFed DAP Free nutrient blends to power your fermentation, we recommend adding Tropic Thunder on top of these additions. Use: For beer or white wine add 0.6 to 2 gram per gallon (0.15 to 0.5 grams per liter) directly into the fermenter at the start of fermentation. Perform bench trials to determine optimal usage or start with a dosage of 1.2 g per gal (0.3 g per liter) and adjust as needed on future batches.

The ideal yeast for producing a very neutral, clean base for hard seltzers, canned cocktails, further distillation, etc.  Works with malt or sugar fermentations Includes nutrients and pH buffers to keep fermentation humming to finish  Able to handle high levels of ethanol and osmotic pressure Ferments clean up to 80°F ​Our motto is to Empower Your Creative Vision. Origin is a unique style of yeast used to create a neutral alcoholic base that acts as the Origin upon which you layer other flavors. Perfect for Hard Seltzers, Canned Cocktails, and whatever else you can dream up. Also great for neutral washes designed for distillation and tough to ferment honey-based mead fermentations. Works on both sugar, honey, and malt-based fermentations. The secret sauce is a very neutral, high alcohol tolerant yeast combined with nutrients and pH buffers. The non-urea-based nutrients help the yeast in simple sugar mediums naturally low in nutrients. pH buffers ensure a high enough pH to allow the yeast to run to completion in even the toughest of situations. The yeast strain used in Origin is a very low producer of H2S and fruity esters resulting in a clean final product. Origin stays clean at higher fermentation temperatures up to 80°F. Origin could technically be called a Turbo Yeast being packed with nutrients. However, we don't like that association as many turbo Yeasts are not selected and assembled for quality and flavor but rather price and speed. Turbo Yeasts also do not include pH buffers. Origin will work with all commonly used sugars, including sucrose, dextrose, and liquid invert sugar. When fermenting wort from malted barley, use our Brutzyme Glucoamylase Enzyme to break down α-1,4 and α-1,6 glycosidic linkages of starch, dextrins, and oligosaccharides for a drier, more fully attenuated final product. Pilot batches should always be performed to find the optimum final product for your further vision. Directions: Add 10 to 20 g per gal (2.5 to 5 g per liter) directly into your fermentation with no hydration required. Ferment between 65 to 80°F (18-27°C). We recommend starting with a dosage of 15 g per gal (4 g per liter) and adjusting as desired in future batches.

Adds mouthfeel and body to wines, seltzers, ciders, etc. Adds perceived sweetness without the concerns of adding residual sugar Helps lock in color by keeping anthocyanins in suspension in red wines Reduces the formation of tartrate crystals in white wine Makes bubbles in sparkling wine rise slower enhancing the appearance LiquiBody by CellarScience is a specialized, pre-liquefied Gum Arabic preparation that adds body and perceived sweetness while stabilizing color and smoothing tannic astringency. LiquiBody is made from high molecular weight polysaccharides which adds the perception of sweetness without having to stabilize residual sugar in your wine. The ability to add body and a little perceived sweetness has many applications. LiquiBody helps keep anthocyanin color compounds in solution, preventing them from precipitating out in the bottle. It is also particularly useful to help keep tartrates in solution when cold stabilization of white wine is not possible.  Popular Uses LiquiBody works really well in hard seltzers to add body and a slight sweetness. LiquiBody is added to sparkling wines to improve mouthfeel while increasing the appearance and fineness of the bubbles. Add perceived sweetness to any wine in your lineup to appeal to a larger portion of the population.  Filtering Add after rough filtration is finished and before or after sterile filtration. LiquiBody is suitable for use with a sterile membrane filter if your wine is very clean and you have prefiltered. If your wine is not prefiltered, and you already suspect you may have issues with sterile filtration, do not use LiquiBody. Dosage: LiquiBody is stabilized with potassium bisulfite which will add less than 1 ppm of SO2 into your final wine. Use: Add 0.75 to 5 mL per gallon. Perform bench trials to determine optimal usage or start with a dosage of 2 mL per gallon and adjust as needed on future batches. Works best at a temperature range between 50-68ºF and a pH of 4 to 5.5. Additional Notes: Once opened, partial bottles of LiquiBody should be refrigerated and used within 30 days. If a container is left open for longer than the suggested use, you can add 1000 ppm of SO2 to extend its life span.

ACID yeast will complete both Lactic and Alcoholic fermentation on its own, producing an acidic beer with light notes of fruity floral esters Shave days off your sour beer making process by skipping the kettle souring step altogether! No need for added equipment to purge your kettle with CO2 or add heating to maintain high temps for lactic fermentation To reduce acidity, pitch an ale yeast strain to stop souring and wrap up alcoholic fermentation Ferment between 66-77°F CellarScience offers high-quality yeast that is easy to use, consistent, and available at a tremendous value Consistent, repeatable results without the need for kettle souring. ACID from CellarScience is a naturally selected, GMO-free yeast strain that has the ability to ferment and sour beer simultaneously. In a traditional kettle souring process, you'll need to pre-boil wort, purge it with CO2, pitch lactic acid, wrap and seal the kettle, and insulate or provide a heat source to maintain lactic acid fermentation temps that may be as high as 100°F+ depending on your chosen pitch. ACID allows brewers to bypass those steps and produce sour beers with the equipment they already own. Pitch directly in your fermenter and ACID yeast will complete both Lactic and Alcoholic fermentation on its own. When allowed to run its course, this yeast produces a rounded, refreshingly acidic beer with light notes of fruity floral esters. If you wish to reduce acidity, simply pitch a regular ale yeast strain when the desired pH is obtained which will hault souring and complete the rest of the alcoholic fermentation. Every batch is PCR tested to ensure quality. Dosage: Homebrew size coming soon! Two sachets are enough to treat a 5-6 gallon batch. When calculating for larger batches, use at a rate of 2.5–4 grams per gallon of wort. We recommend rounding up by one full sachet rather than measuring out the yeast exactly. Direct Pitch or Rehydrate: ACID yeast is designed to be sprinkled directly onto the surface of your wort with no oxygenation required in the initial fermentation. Our aerobic growth process makes this possible by creating dry yeast with high viability and high sterol levels. ACID yeast is pre-loaded with essential nutrients to ensure a successful, complete fermentation. While not required, some brewers prefer to rehydrate yeast. To hydrate yeast, first, sanitize the yeast brick and scissors. Use 10 grams of sterilized tap water between 85-95°F (29-35°C) mixed with 0.25 grams of FermStart per gram of yeast. Sprinkle yeast on the water. Allow the slurry to stand undisturbed for 20 minutes, then swirl. Use small amounts of wort to adjust to within 10°F (6°C) of wort temperature before pitching. Ferment between 66-77°F (19-25°C). Optimum Fermentation Temp: 66-77°F Flocculation: High Alcohol Tolerance: 9% ABV Attenuation: 75-80% Lachancea thermotolerans Gluten-free CellarScience Yeast: For years liquid yeast has been sold as the higher quality option but times are changing. Yes, 20 years ago dry yeast was made by bread yeast producers and the quality was not as good as liquid yeast. CellarScience is helping to flip that script with a full lineup of high-quality dry yeasts. Cell count and viability is usually higher than commercial liquid yeast pitches, which vary from pouch to pouch and don't ship well. CellarScience yeast can be pitched directly in most batches of wort, offering significant time savings. Yeast that is quick and easy to use, high quality, and available at a reasonable cost adds up to a tremendous value. Quality yeast that doesn't "break the brink". CellarScience Nutrients: For high gravity ferments consider rehydrating yeast with CellarScience FermStart yeast hydration nutrient. For high gravity or low nutrient wort, feed your fermentation with CellarScience FermFed DAP Free complex yeast nutrient mix.

Recomended for aged red wines High color extraction Significant polysaccaride and glycerol production for huge mouthfeel High alcohol tolerence High nutrient need Top choice for Bordeaux varietals Cabernet, Cab Franc, Petite Verdot and Merlot Also excelletnt for Sangiovese, Nebbiolo and some Pinot The name kind of says it all. BIG RED is ideal for producing big, complex red wines with lasting fruit. Depending on the grape varietal used it can emphasize complex berry fruit and spice flavors. This strain is very efficient at breaking down and extracting tannins and anthocyanins from grape skin walls, making wines with dark inky color and a tannin profile suitable for extended aging. BIG RED also produces a great mouthfeel due to the significant production of polysaccharides and glycerol. It is also tolerant to higher alcohol levels making it ideal for those grapes that need to stay on the vine just a little longer to get full phenolic ripes with smooth tannin profiles. So lets recap... emphasizes berry fruit with many varietals, produces dark color, extracts a full array of tannins suitable for extended aging, makes wines with great mouthfeel, and is resistant to higher alcohols. Is there a catch? No, but to get all that done BIG RED does love nutrients and you will need to feed it and pay attention to it during fermenation. This is a strain where you would ideally know your Free Available Nitrogen levels that you could base a nutrient schedule around. Absent those numbers or a history with the grapes you are fermentiing, we would suggest you start with hydrating with Fermstart, feeding with FermFed DAP free at the onset of fermentation and feeding again with regular Fermfed after 1/3 sugar depletion. BIG RED is a very low producer of H2S when nutrient demands are met. The perfect strain if you want to make amazing reds. Not the perfect strain if you have a vacation planned during the middle of fermentation and are going to ask your neighbor to punch down...we hear it all!. Because this strain respects varietal character it can be used for a broad spectrum of red grape varietals. Perfect of courese for those Bordeaux varietals ilke Cabernet Sauvignon, Cabernet Franc, Petit Verdot and even Merlot. Also our first choice for Nebbiolo and some bigger style Sangiovese and Pinot Noir.   Start Time: Fast    Alcohol tolerance: 16%+    Nitrogen demand: high      Yan Requirement @ 23 Brix: 270ppm    Production of volatile acidity: Low      Production of SO2: Low Ease to Ferment with MLF: Average  Yeast type: Cervisiae  Killer Factor:  Neutral      Malic Acid Consumption: Average Optimal Fermentation Temp: 65–85°F   Proper yeast hydration helps ensure a healthy fermentation. For every gram of yeast, mix .25 g of FermStart yeast nutrient with 25 ml of sterilized tap water between 104–106°F/40–41°C. When water reaches 104°F/40°C, sprinkle yeast into water and stir gently. Allow the slurry to stand undisturbed for 15 minutes and then stir again. For every gram of yeast used add 25 ml of clean must to the yeast slurry and let stand 15–20 minutes. If necessary, use additional must to adjust yeast slurry to within 18°F of must temp before pitching.

Produces ß-glucosidase to cleave terpenes Floral, Rose, Citrus flavors Will not produce volatile phenols Best choice for Muscat/Moscato & Gewurztraminer. Also great for Sauvignon Blanc, Riesling and Viognier Those floral, rose, citrus, and stone fruit aromatics are bound all up in terpense in your grape skins and you know, they would really like to get out. It's your job to free them, package them in a bottle, and eventually let them waft out of a wine glass and into the nasal cavity of someone who appreciates excellence. We can help you do this. If you are making a higly aromatic white such as Muscat, Gewürztraminer, Viognier, Sauvignon Blanc or Riesling this is the ideal yeast. BOUQUET is known for its production of the enzyme ß-glucosidase which liberates aromatic compounds by cleaving terpenes from the sugars that bind them and releasing their goodness. This yeast will turn these certain grape varietals from ordinary white wines to highly aromatic, very special white wines that smell and taste amazing. The type of wine where 'stuff' wafts out of the glass! Also interesting is that most yeasts have the potential to produce phenolic off flavors, which in high quantities produce a paint like aroma (yuck!), if the conditions are less than ideal. However, BOUQUET is POF (phenolic off flavors) negative and will synthesize phenolic off flavors, eliminating that risk. This is a great yeast to co-ferment with Luscious for added complexity. Additional Fermfed nutrient is recommended at the start of fermentation due to the short lag phase of this strain. Due to such a rapid period of growth, the yeast cells require higher levels of nutrients to ensure a healthy fermentation. If you have had your wine tested and know your Yeast Available Nitrogen (YAN) follow our CellarScience nutrient feeding schedule accordingly. If you don't know your YAN we recommend hydrating with Fermstart, feeding with FermFed at the onset of fermentation and feeding again with regular Fermfed after 1/3 sugar depletion. Normally the feeding at the onset of fermentation would be with Fermfed DAP free but in this case BOUQUET can use the extra DAP kick that Fermfed provides.   Start Time: Fast    Alcohol tolerance: 14%    Nitrogen demand: Very High  Yan Requirement @ 23 Brix: 340 ppm    Production of Volatile Acidity: Low    Production of SO2: Average  Cap/Foaming: Average  Ease to Ferment with MLF: Low    Malic Acid Consumption: Average    Killer Factor:  Positive (though is able to coferment with Luscious) Yeast Type: Cerevisiae Optimal Fermentation Temp: 50–80°F   Proper yeast hydration helps ensure a healthy fermentation. For every gram of yeast, mix .25 g of FermStart yeast nutrient with 25 ml of sterilized tap water between 104–106°F/40–41°C. When water reaches 104°F/40°C, sprinkle yeast into water and stir gently. Allow the slurry to stand undisturbed for 15 minutes and then stir again. For every gram of yeast used add 25 ml of clean must to the yeast slurry and let stand 15–20 minutes. If necessary, use additional must to adjust yeast slurry to within 18°F of must temp before pitching. For a complete nutrient schedule sufficient for most fermentations, add 1.5 g of FermFed DAP Free per gallon of must at the first sign of fermentation and 1 g of FermFed per gallon of must after 1/3 sugar depletion.   Click here for a PDF of the MoreWine Yeast and Grape Pairing Guide.

Autolyzing, quick release of polysaccarides such as mannoproteins Top choice for sur lie aging Ability to ferment cold for clean flavor with emphasis on mouthfeel and toastiness of sur lie aging When fermented warmer exoctic tropical flavors shine Frequently used to make luscious Chardonnays and similar white wines Luscious Chardonnays with creamy mouthfeel and deep complexity... if that is your end point, LUSCIOUS is your starting point. LUSCIOUS can be fermented at different temps depending on your style preference. Ferment it cooler, it can handle it, and put the emphasis on the creaminess and the toasted champagne-like complexity of sur lie ageing. Or crank it up a bit warmer and add in some more tropical notes, your choice. However the magic of LUSCIOUS really happens after fermentation when this yeast goes naturally goes nuclear, implodes and breaks open its cell walls, during a process called autolysis. Polysaccharides such as mannoproteins are released into the wine... and man, it's all about those mannoproteins creating that rich, creamy mouthfeel that so many Chardonnay drinkers seek out. The silky richness is emphasized even futher by sur lie aging, aging on clean lees for a period of time, in either tank or barrel. Being a low producer of SO2 it is naturally great candiate for later malo-lactic fermentations. Now that we have painted a picture try putting this marketing wizardry on your next label "The 10-40w viscosity of this wine is due to it being loaded with mannoproteins from the guts of exploded yeast cells". Maybe leave us out of the wine marketing department but we do know a winning yeast when we taste it. #1 for this style of Chardonnay but also a top choice for Viognier and other whites. Optimal Fermentation Temp: 55–68°F Start Time: Average  Alcohol Tolerance: 14%+ Nitrogen Demand: Average YAN Requirement @ 23 Brix:  245 ppm  Production of volatile acidity: Average  Production of SO2: Low  Cap/Foaming:  Low  Ease to Ferment with MLF: Good  Lees Aging: Best Choice     Proper yeast hydration helps ensure a healthy fermentation. For every gram of yeast, mix .25 g of FermStart yeast nutrient with 25 ml of sterilized tap water between 104–106°F/40–41°C. When water reaches 104°F/40°C, sprinkle yeast into water and stir gently. Allow the slurry to stand undisturbed for 15 minutes and then stir again. For every gram of yeast used add 25 ml of clean must to the yeast slurry and let stand 15–20 minutes. If necessary, use additional must to adjust yeast slurry to within 18°F of must temp before pitching. For a complete nutrient schedule sufficient for most fermentations, add 1.5 g of FermFed DAP Free per gallon of must at the first sign of fermentation and 1 g of FermFed per gallon of must after 1/3 sugar depletion.

Add to Red Wine Fermentation on the skin Binds with anthocyanins and stabilizes color Improves mouthfeel and body Mix of both ellagic and proanthocyanidin tannins CellarTan F is designed to be added to red wine fermentations where it binds color, improves body and mouthfeel, and softens the overall tannin profile. Used during the early stages of fermentation when anthocyanins are being released from the grape skin in the presence of alcohol and need to be stabilized for long term color retention. CellarTan F is a combination of ellagic tannins and proanthocyanidin tannins. Ellagic tannins are hydrolysable oak tannins that break down in wine. They react with grape skin derived phenolics to form flavono-ellagitannins which are hybrid compounds that play a key role in color stability while also softening the mouthfeel of your wine. Ellagic tannins also have potent antioxidant properties that reduce the need for SO2. Proanthocyanidin tannins, or condensed tannins, also contribute to color stability, taste, and mouthfeel. Through polymerization, anthocyanins cap the end of tannin chains to form stable color throughout the life of your wine. They also increase the body and structure of wine. Use: Dissolve 0.2 to 2 g per gallon (0.05 to 0.5 g per liter) in juice or water. Add to must at least 30 min after any SO2 addition and mix well. If you are unsure where to start within the suggested range, we recommend a dosage of 1 g per gallon (0.25 per liter) and adjust as desired on future fermentations.

Protects against oxidation Preserves Terpenes, Esters, and Thiols (3MH, 3MHA) during aging Reduces need for SO2 Improves color stability CellarScience GSH Naturale was designed for winemakers who want to take advantage of the benefits of Glutathione. Glutathione reduces browning in all wines but is especially useful in whites. In whites with higher levels of terpenes and thiols (e.g. Sauvignon Blanc and Viognier) GSH helps preserve fruity/floral aromas. It is also particularly helpful to produce natural wines or wines with less SO2. How it Works: Quinones are a class of compounds that can degrade wine by causing oxidizing reactions that lead to browning and the loss of desirable varietal flavors. Terpenes and Thiols are particularly prone to interact with Quinones. Instead GSH reacts with Quiniones creating a stable compound that does not lead to browning and a loss of flavor and aroma. GSH is a natural compound found in yeast cells and acts as a natural anti-oxidant that can be used in conjunction with SO2 or by itself in the case where the winemaker chooses to use low or zero quantities of SO2. GSH Naturale contains a high percentage of tripeptide glutathione along with other polysaccharides that have a positive impact on body, flavor, aroma. Usually used in conjunction with SO2 as an additional natural inhibitor of browning, GSH Naturale will have positive impact on color, wine, thiol, esters and terpene content throughout the aging process. Use: Add 0.4 to 1.5 grams per gallon (0.1 to 0.4 g per liter) directly into the wine. We recommend starting with a dosage of 1 g per gallon (0.25 g per liter) and adjusting as desired in future batches.

All the benefits of Sur Lie aging without the risks Luxurious, soft mouthfeel Perfect for your big body whites Helps reduce browning Produced from yeast cells and considered an SIY (especially inactivated yeast) CellarScience Easy Sur Lie offers all the benefits of doing a sur lie aging without the risk. Sur lie aging, often also referred to by the French term Battonage, is the process where wine is left on the original lees. or yeast, at the end of fermentation. Battonage specifically refers to the process of stirring lees back into solution over a few weeks to add body and richness to the wine. Exactly how it is done depends on the winemaker. Some choose to leave the wine on the gross lees while some choose to remove the wine quickly from the gross less and then stir up a clean version of the remaining yeast that settles out. Either way, there is some risk in this process of extracting some flavors you don't want while also potentially adding unwanted oxygen into the wine. During Sur lie the yeast cells are breaking down, releasing peptides, mannoproteins, and anti-oxidant amino acid proteins, and other yeast cell compounds. These compounds add that luxurious, soft mouthfeel to wine that is so desired. CellarScience Easy Sur Lie adds these compounds into the wine without having to take the risk and time/cost of doing an actual Sur Lie aging and stirring protocol. Easy Sur Lie also has some extra benefits. It helps prevent the formation of mercaptans, reducing potential sulfur compounds that can mask the full potential of your wine. It also functions as an antioxidant. Yeast at the bottom of naturally carbonated beer bottles is long known as an antioxidant that helps keep packaged beer fresher longer. Easy Sur Lie in your wine works in a similar way, supporting SO2 to help ensure freshness and reduce browning reactions. Can be added at the end of fermentation and throughout the aging process. Use: Mix 1.5 g per gal (0.4 g per liter) for best results. Add at the last stages of fermentation or early in aging for the furthest integration and best results.

Prevent volatile acidity in fermentation before it happens Add at first signs of a problematic ferment to help limit the production of volatile acidity Avoid a malolactic fermentation (MLF) in White Wines Use as an insurance policy during barrel aging of Red Wines to reduce the risk of volatile acidity CellarScience Killazyme is a lysozyme that is used to control and inhibit gram-positive lactic acid producing bacteria including Oenoccoccus, Pediococcus, and Lactobacillus.  This is a tool winemakers can use throughout the winemaking process to limit bacteria contamination and the production of volatile acidity. Killazyme does not affect gram-negative Acetic Acid bacteria nor yeast.   Don’t Use Killazyme If You Are Coinoculating Yeast and ML When performing a “secondary” malolactic fermentation (MLF) we want lactic acid Bacteria to convert the harsher malic acid into lactic acid. Mostly MLF fermentations are done sequentially with the sugar fermentation being completed first followed by the MLF fermentation second. If you are doing a co-inoculation of yeast and lactic acid bacteria during the primary ferment, do not use Killazyme.   Use Killazyme to Prevent Volatile Acidity in Fermentation Killazyme can be added at the start of fermentation to limit lactic acid bacteria before it happens. Under certain situations lactic acid can use sugar or citric acid which it converts into acetic acid and volatile acidity. Killazyme is effectively used at the start of fermentation when you know or suspect a slow to start fermentation. This might be a result of a cold soak or those ferments relying on native yeast. Once your yeast starts to rip, the potential action of lactic acid bacteria is greatly suppressed and the need for Killazyme is reduced. At the back end of fermentation, slow, struggling fermentations caused by various reasons, such as temperature or high sugar, can cause bacteria to consume sugar and citric to produce acetic acid and volatile acidity. Additionally, if lactic acid bacteria fully converts the available malic acid the bacteria can pivot to sugar and citric product volatile acidity. In a problem ferment where the yeast are already struggling, volatile acidity acts as a double whammy suppressing yeast activity even further. If you suspect a problem finish, based on past experience or current conditions, Killazyme is a great tool to add at the start of fermentation Use Killazyme at First Signs of Problem Finish Killazyme can also be added at the first signs of a problematic ferment to help limit the production of volatile acidity. This reactive addition requires a heavier dosage than a preemptive addition as there is most likely volatile acidity already present.   Use Killazyme to Avoid MLF in White Wines When fresh, crisp white wines are desired, Killazyme can be added at the start of a white wine fermentation, or at any point in tank or barrel, to block lactic acid activity and prevent MLF. We still always recommend a sterile filtration for commercial whites before bottling to prevent a later MLF in the bottle. .  Killazyme is also great if you are going to be blending whites where one white went through and MLF and the other white did not.    Barrel Storage Protection of Reds After MLF is complete and you storing wines in barrel Killazyme is a great insurance policy to reduce the risk of volatile acidity.  Use: To Delay Malolactic Fermentation: Red Wine - add to grapes at 100 - 200 ppm, or 0.38 - 0.76 grams per gallon. White Wine - Add to must at 200 - 300 ppm, or 0.76 - 1.14 grams per gallon. To Block Malolactic Fermentation: White Wine - Add to must or wine at 300 - 500 ppm, or 1.14 - 1.90 grams per gallon. Stabilizing Wine After MLF is Complete: Add to barrel during storage at 250 - 500 ppm, or 0.95 - 1.90 grams per gallon. When Blending Partial and Complete MLF Wines: Add immediately after blending at 300 - 500 ppm, or 1.14 - 1.90 grams per gallon, to reduce the risk of further malolactic fermentation (MLF). Within several days any lactic should expire. For Sluggish or Stuck Yeast Fermentation: Red Wine - Add at 150 - 400 ppm, or 0.57 - 1.52 grams per gallon. White Wine - add at 300 - 500 ppm, or 1.14 - 1.90 grams per gallon. You can make a 10% solution of Killazyme in water (100 grams per liter of water). However, we find the easiest method is to add the desired dry weight of Killazyme in 5x its weight of warm (tepid) water. Mix for one minute, allow this mixture to stand for 45 minutes and add to must, juice or wine while mixing well. Allow 24 - 48 hours for reaction to complete.
