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.

Optimum Fermentation Temp: 54-64°F
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.

Superior Yeast Health: Stabilizes cell membranes and reinforces stress tolerance, ensuring high viability in high-gravity brews and repitched batches.
Optimized Flavor Profile: Promotes clean fermentation by reducing harsh fusels and balancing ester production for a more refined finished product.
Absolute optimum value for delivering zinc to your yeast.
CellarScience FermZn Plus is an advanced yeast-derived nutrient designed to correct zinc deficiencies and restore complete fermentation performance. Zinc is one of the most critical trace elements in brewing and fermentation science it serves as a catalytic cofactor for key enzymes, including alcohol dehydrogenase, which is essential for ethanol production and redox balance. Yeast cells depend on zinc to stabilize cellular membranes, regulate stress-response proteins, and maintain the structural integrity of enzyme complexes involved in sugar metabolism. When zinc is limited, fermentation slows, higher alcohols and esters become unbalanced, and yeast viability declines especially in high-gravity or repitched conditions.
FermZn Plus delivers an exceptionally concentrated level of zinc 5.5–6.5 % w/w elemental content—representing one of the highest bioavailable zinc concentrations achievable in a yeast-bound form. This massive zinc load ensures full metabolic activation of zinc-dependent enzymes, stabilizes cellular membranes, and enhances redox control, even in the most demanding high-gravity or nutrient-limited fermentations.
By supplying zinc in a yeast-bound, bioavailable form, FermZn Plus bypasses the poor solubility of inorganic zinc salts, allowing yeast to uptake and utilize it efficiently throughout the entire fermentation cycle. The result is faster attenuation, reduced lag phase, cleaner flavor development, and healthier yeast for subsequent repitches.
Bioavailable Zinc Complex: Delivers 5.5–6.5 % w/w elemental zinc bound within a yeast matrix for direct metabolic utilization among the highest yeast-bound zinc concentrations in fermentation science.
Supports Alcohol Dehydrogenase Activity: Enhances the enzymatic conversion of acetaldehyde to ethanol for complete fermentation and reduced off-flavors.
Accelerates Sugar Metabolism: Improves glycolytic pathway efficiency, leading to faster attenuation and reduced residual sugars.
Protects Yeast Cell Structure: Reinforces membrane stability, improving osmotic and ethanol tolerance under stress.
Improves Repitching Viability: Maintains intracellular zinc reserves for consistent fermentation performance across multiple generations.
Optimizes Flavor Balance: Reduces harsh fusel formation while promoting desirable ester synthesis for a refined fermentation profile.
YAN Neutral: Provides essential micronutrients without altering total nitrogen contribution or impacting nutrient balance.

Note: These salts are designed to set mash pH without acid additions. Because malt acidity varies, you may wish to verify your mash pH and make small corrections if needed, though this is rarely necessary. Dextrose is used in trace amounts as a processing aid for blend consistency and flow and does not affect fermentation or flavor.
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.

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.
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:

F-2 was specifically selected for secondary fermentation in bottle and in cask
Neutral aroma profile and high alcohol resistance make it perfect for refermentation bottle conditioning
Sticks well at the bottom of the bottles/casks
Fermentis active dry yeast offers reliability, ease-of-use, and consistency to home and professional beverage makers across the world
SafAle™ F-2 is specifically selected for secondary fermentation in bottle and in cask. This yeast assimilates very little maltotriose but assimilates basic sugars (glucose, fructose, saccharose, maltose) and is characterized by a neutral aroma profile respecting the base beer character. Its neutral aroma profile, high alcohol resistance and stickiness characteristics make it a perfect match for consistent re-fermentation in bottle and cask.
SafAle™ F-2 resists to high alcohol levels (>10% v/v) and allows brewers to obtain all the properties of refermentation such as:
Beer preservation thanks to oxygen trapping
Contribution in roundness and maturation aromas
Carbonation
Sticks well at the bottom of the bottles/casks and forms a nice haze when it is resuspended
Usage:
Add 19 to 38 grams of sugar per gallon of beer (5 to 10 grams of sugar per liter) to obtain a saturation of 2.5 to 5.0 g/l of CO2
Pitch the sweetened beer, that should be at fermentation temperature (68-77°F / 20-25°C) with the rehydrated yeast. Carbonation will be achieved in 1 to 2 weeks at 68-77°F. Carbonation at 59°F can take over 2 weeks
At the end of refermentation, the beer can be cooled down and will gain in roundness after 2 to 3 weeks

Sourvisiae® is a modern fermentation solution that produces sour beers through one simple fermentation step
Clean and neutral flavor, ideal for traditional and modern sour beer styles and an excellent base for fruited sours
Sourvisiae® is a bioengineered (GMO) strain of Saccharomyces cerevisiae
Lallemand premium brewing yeast offers brewers unmatched consistency, reliability and purity from one batch of beer to the next
Sourvisiae® is a bioengineered ale yeast strain (Saccharomyces cerevisiae) capable of producing lactic acid during fermentation to provide brewers with an easy, reproducible, and mono-culture product for sour-style beer production.
Sourvisiae® contains a single genetic modification, a lactate dehydrogenase gene from a food microorganism, which enables the yeast to produce high levels of lactic acid, the main compound that gives sour beers their flavor. Sourvisiae® allows the brewer to ferment and sour the beer in one simple step, reducing cross-contamination risks, lowering costs, cutting total process time, and allowing brewers to obtain a consistent product. The brewing process is conducted without any modifications; Sourvisiae® is pitched just like conventional yeast and ferments in a normal fermentation time. Sourvisiae® does not produce other flavor compounds associated with Brettanomyces, Lachancea, or Lactic Acid Bacteria, providing a cleaner and more reproducible souring process, with much shorter fermentation times.
Microbiological Properties
Classified as a bioengineered Saccharomyces cerevisiae, a top-fermenting yeast. Finished product is released to the market only after passing a rigorous series of tests. *According to the ASBC and EBC methods of analysis.
Typical Analysis of Sourvisiae® Yeast:
Percent solids 93% – 96%
Living Yeast Cells ≥ 5 x 10 9 per gram of dry yeast
Wild Yeast < 1 per 10 6 yeast cells
Bacteria < 1 per 10 6 yeast cells
Brewing Properties
In Lallemand’s standard conditions, wort at 20°C (68°F), Sourvisiae® yeast exhibits:
Vigorous fermentation that can be completed in 5 days
Medium to High Attenuation and Medium to High Flocculation
Highly acidic and slightly fruity flavor and aroma
The optimal temperature range for Sourvisiae® yeast when producing traditional styles is 15°C (59°F) to 22°C (72°F).
Fermentation rate, fermentation time and degree of attenuation are dependent on inoculation density, yeast handling, fermentation temperature and nutritional quality of the wort.
Attenuation may appear lower due to the formation of lactic acid. Production of lactic acid does not result in a loss of CO2. When sugar is consumed to produce lactic acid, there is no change in density. Therefore, the amount of residual sugar in the finished beer is lower than the final density would imply.
This yeast produces a very acidic beer, with final beer pHs in the range of 3.0 and lactic acid in the range of 8 – 15g/L. Vigorous fermentation can be completed within 5 days.
The resulting flavor and aroma profile of the beer is a slightly fruity acidic beer. Because of the resulting low pH and highly acidic conditions, we do not recommend re-pitching this yeast.
Flavor and Aroma
Tangy, sour, slightly fruity

The intensity is medium at high fermentation temperatures, and at lower temperatures, it will be less intense.
Fermentation
Eitrheim ferments well from 59°F up to 100°F. The higher fermentation temperature, the faster fermentation. At the optimum temperature 88-95°F expect fermentation to finish in 72 hours. When fermentation is done at low temperatures you can expect fermentation time to increase. For high gravity beers, we recommend users to pitch two packs of yeast and add yeast nutrition to ensure a healthy fermentation.
Pitching
Pitch directly into wort by sprinkling it across the surface, or rehydrate yeast. For fermentation below 64°F, or high gravity, increase pitching rate to 2.25 g/Gal.
One 7 g sachet treats 5 to 8 gallons of wort.
One 300 g brewery pouch treats 8.5 bbl of wort.

Prevents Off-Flavors: ALDC from CellarScience helps prevent the production of Diacetyl, a butter-like off-flavor, ensuring a cleaner-tasting beer.
Reduces Conditioning Time: By limiting Diacetyl production during dry hopping or fermentation, ALDC reduces the time needed before your beer is ready for bottling or kegging.
Versatile Use: ALDC can be added during yeast pitching or dry hopping, benefiting any beer style, especially those with heavy dry hopping, by controlling hop creep.
Stop hop creep before it happens with ALDC from CellarScience. As modern beer styles call for increasing amounts of dry hops, a new risk for off-flavor in the finished beer arises. Hop creep is the result of yeast beginning a new fermentation when dry hops with trace amounts of fermentable sugars are introduced to the finished beer. This results in further production of Diacetyl and, if yeast are not given enough time to clean up after themselves, can lead to higher levels of Diacetyl in the finished beer. Diacetyl is often referred to as a butter or butterscotch like flavor and is not desirable in most styles, especially at high levels. ALDC, or alpha acetolactate decarboxylase, is a helpful enzyme that can be added at yeast pitching or along with your dry hops to limit the production of Diacetyl to protect your finished beer from off-flavors and reduce the conditioning time needed before its ready to bottle or keg.
Use:
Available in 1 oz dropper bottle or 8 oz bettix bottle. Add to fermenter at time of yeast pitching or dry hopping at a rate of 1 dropper full per 5 gallons. 1 oz contains approximately 35 doses.
Additional Notes:
Although commonly added to heavily dry hopped beers, using ALDC during fermentation can benefit any beer style by reducing Diacetyl production. Brewing hops all contain the naturally occurring enzyme AMG or amyloglucosidase which breaks down long chain sugars into simple sugars that yeast can ferment. The reason hop creep is a relatively new phenomenon is due to the changing ways in which hops are dried and processed. As brewers started to demand more aromatics from their hops, growers began to lower the kilning temperatures to preserve volatile oils. This led to higher levels of AMG left on the hops as well, where they were previously denatured at the higher kilning temperatures. With more AMG present on the hops, dry hopping now leads to more fermentation activity and higher levels of Diacetyl produced after the primary fermentation is complete. Although the simplest remedy to hop creep is time—waiting for the yeast to naturally clean up the extra Diacetyl—ALDC is a great way to reduce conditioning time and the risk of off-flavors in your finished beer.
The recommended shelf life is 12 months from the date the package is opened.

Seltzer-Specific Formula: Provides the precise Free Amino Nitrogen (FAN) and nutrients lacking in sugar bases for a clean fermentation.
Rapid & Clean Fermentation: Achieve a finished seltzer in as few as 5 days with a neutral flavor profile.
Prevents Off-Flavors: Designed to help yeast avoid producing common off-flavors (fusel alcohols, acetaldehyde, sulfur).
Easy to Use: Dissolves quickly and completely without the need for stirring or heating.
Nutrient blends designed for fermenting wine or beer simply don’t cut it when it comes to crafting seltzers. Both grape juice and wort naturally contain baseline levels of nutrients and free amino nitrogen (FAN) that are absent in seltzer bases. Simply increasing the dosage of nutrients intended for beer or wine fermentation isn’t effective. While this approach may meet the nutrient requirements, yeast need a certain level of FAN to ferment seltzers efficiently and cleanly. Unfortunately, most nutrient products on the market fall short of this mark.
Some solutions promote nitrogen bound within dead yeast cells, like our own FermFed DAP Free, as being suitable for seltzers. However, after extensive trials, we’ve found that this approach doesn’t deliver the neutral flavor profile needed for the best seltzers. While fermentations may complete, they often do so with unwanted yeast-derived off-flavors. Yeasts that struggle to finish tend to produce fusel alcohols, acetaldehyde, and sulfur compounds.
Our Dynamo 800 Nutrient is specifically formulated to provide yeast with everything they need to achieve a clean fermentation in as few as 5 days. When designing this nutrient, a decision was made to make flavor the top priority. Additionally, it dissolves easily without the need for stirring or heating, making it simple and efficient to use. Dynamo includes both organic and inorganic nitrogen to achieve a fast, clean fermentation in the challenging environment of seltzer production. Like the 800-meter race, it’s not just about pure speed—it’s about endurance and precision. While some products prioritize fermentation speed alone, we believe Dynamo 800 Nutrient strikes the perfect balance. It has been designed to go the distance and deliver the best flavor, especially when paired with CellarScience VELO.
