Wine Making Additives (During Ageing)

Smart brewers know that a yeast starter is the best way to ensure proper cell count and yeast viability prior to pitching. If you want a reliable starter for your batch of beer, you need to feed the yeast. Adding a yeast nutrient to the starter will give the yeast an added boost! Fermaid K is a yeast nutrient that works for starters and main fermentation. Here’s how it works:   Fermaid K is a complex formula that provides DAP, free amino acids, yeast hulls, unsaturated fatty acids, sterols; and micronutrients such as magnesium sulfate, thiamin, folic acid, biotin, calcium pantothenate, and other vitamins and minerals. Yeast use Nitrogen for protein synthesis and to maintain cellular growth. Nitrogen from the alpha amino acids contained in Fermaid K is utilized much more efficiently than from the ammonia salts like DAP. The unsaturated fatty acids and sterols available in Fermaid K are important survival factors needed to maintain alcohol resistance. They also help keep volatile acidity levels low. The cell wall fractions, available through the included yeast hulls, absorb medium chain fatty acids that are toxic to the yeast. They also provide nucleation sites to help keep the yeast in suspension. You do not need to add any additional fertilizers or DAP when adding Fermaid K. Use approximately 1 gram per gallon. Rehydrate in distilled water.   A rough approximate of weight is 1 tsp = 4.7 grams. We highly recommend using a scale to weigh the product for an accurate dose.   For a similar product check out CellarScience® FermFed Yeast Nutrient!

The Fermaid line of products are a range of nutrients that have been adopted from winemaking and put to use supporting beer fermentations as well.     Fermaid O is a newer formulation of the long trusted Fermaid K nutrient which replaces the inorganic DAP in Fermaid K with an organic source of nitrogen instead. The organic nitrogen in Fermaid O is better for your yeast, and that results in better beer!   Organic Nitrogen is easier for your yeast to digest, resulting in a smoother, more consistent fermentation. Fermaid O fermentations show fewer temperature spikes, which minimizes negative effects that can be caused by heat. Compared to DAP, Fermaid O results in more consistent and complete fermentation, and lower levels of negative sulfur compounds and other off-flavors.   Use at a rate of 1.5g / gal of wort. Dissolve in a small amount of wort or water and add to your fermenter at pitching.   Like Fermaid O? Then you will love CellarScience™ FermFed DAP Free Yeast Nutrient!

A new, advanced formulation of Go-Ferm Go-Ferm Protect is a natural yeast nutrient that is added to the yeast hydration water before adding your selected yeast strain. Its complex formula provides your yeast with the proper sterols, unsaturated fatty acids and micronutrients needed to begin fermentation in optimal shape. The great thing about Go-Ferm Protect is that the proper nutrients and vitamins are introduced BEFORE the yeast is added to the must. This way 100% of the nutrients are available to your selected yeast strain and won't be stolen away by any indigenous yeast or bacteria that may be present in the must before your yeast can become established. Go-Ferm Protect was created as a result of a multi-year study of problem fermentations by Lallemand and the National Agricultural Research Institute (INRA) in France. During this period, they looked at the adverse effects on the yeast from overripe fruit (>28 Brix), low nutrient levels, overclarification of the juice and poor fruit quality (Botrytis, rot, high bacteria count, insecticide and fungicide residue). Their research showed that musts deficient in sterols and unsaturated fatty acids made yeast more susceptible to ethanol toxicity (high alcohol), osmotic shock (high sugar), temperature and others stress factors. In response to this data they created the NATSTEP (NATural STErol Protection) process that incorporated sterols, unsaturated fatty acids, as well as vitamins and minerals into an advance yeast hydration nutrient: Go-Ferm Protect. Go-Ferm Protect provides a combination of protective and nutritional benefits that ensure your yeast begins your fermentation in peak form! The best part is that if your fruit is in great shape then Go-Ferm Protect will simply help your yeast out that much more! Go-Ferm Protect does not contain any DAP, as DAP is harmful to the yeast during the rehydration process. GO-Ferm is usually used in conjunction with our Fermaid K yeast nutrient; where Go-Ferm Protect is used at yeast hydration then Fermaid K is added at the first signs of fermentation and again after 1/3 sugar depletion. Use: Use at a rate of 1.25 g Go-Ferm Protect per 1 g of yeast. A rough approximate of weight is 1 tsp = 3.2 grams. We highly recommend using a scale to weigh the product for an accurate dose. We do not recommend relying on these rough conversions for accurate dosage rates. Click Here for a copy of MoreWine!'s Guide to Yeast Rehydration Like Go Ferm Protect?

Calcium carbonate is used to reduce the acidity of wine. It does not require cold-stabilization to force complete precipitation, as does potassium carbonate. However, calcium carbonate is more likely to affect the flavor than potassium carbonate, and may take a few months to fully precipitate. One-quarter ounce (about 4 teaspoons) of calcium carbonate reduces acidity in one gallon by about 0.25%. Foaming may occur because of the production of CO2. Do not use more than one ounce per gallon. Wait 24 hours and rack wine. Calcium carbonate is also used in beer to increase the temporary hardness of water. Traditionally used in English stouts, pale ales and bitters. Usage: Usage varies with acid level Common name: Chalk

Potassium Metabisulfite, (often referred to as "SO2", "sulfites" "meta", or "meta-bi") has several uses in winemaking. At the crush, sulfites are generally used to help control the spoilage bacteria and indigenous yeast that may already be present both on the fruit and in the winery (i.e. on the picking bins, processing equipment, tanks, tubing, etc). The amount generally used is enough to inhibit most of the unwanted organisms but not enough to hinder a cultured yeast, which has a higher tolerance to sulfites than most of the indigenous organisms do. This inhibition effectively "wipes the slate clean" for the cultured yeast to step in and rapidly colonize the must so that it can effectively dominate the subsequent fermentation. In addition, sulfites also help to inhibit the enzymatic browning of both musts and finished wines so that all of their delicate complexities can be preserved. Later, during storage and in the bottle, sulfites at the proper levels will further protect a wine by continuing to inhibit spoilage organisms, as well as by scavenging oxygen. Note that the exact amount needed to effectively do the job is determined by the pH of the wine. Refer to our MoreManuals! on Red or White Winemaking or one of the winemaking books that we offer for a complete explanation on how to properly manage sulfites. In addition, it's important to keep in mind that free SO2 levels fall faster in wood cooperage than in glass or stainless, so if you are using a barrel you will most likely need to manage sulfite levels more closely. The most common form of Metabisulfite is as a powder which is fixed with potassium or sodium. 1/4 tsp of Potassium Metabisulfite adds 50ppm to 5 gallons of must. Old Metabisulfite loses potency with time and should be replaced every year to assure that you are getting correct levels. You can use old Metabisulfite to make solutions for sanitizing equipment.

Sorbistat K, Potassium Sorbate, ensures against renewed fermentation in wine when residual sugar is added post the initial ferment. Add at the rate of .5 to .75 grams per gallon (125-200ppm) in conjunction with .3 grams of meta-bisulphite (50ppm) per gallon. Use the higher end of the range (200 ppm) as the wine's pH approaches or exceeds 3.5 or when the alcohol conent of the wine is below 10%. Note: Will not stop an active fermentation. Potassium sorbate should not be used if the wine underwent an ML fermentation because sorbic acid (in the potassium sorbate) will react with lactic bacteria to produce a "geranium" smelling off-flavor. A rough approximate of weight is 1 tsp = 2.3 grams. We highly recommend using a scale to weigh the product for an accurate dose. We do not recommend relying on these rough conversions for accurate dosage rates.

When you make a specialty beer with fruit, you want it to look brilliant as well as taste amazing. This Pectic Enzyme will take the haze out of your brew and keep it looking clear.   Pectic Enzymes are used to reduce the hazing effect of pectins when using real fruit in your beer, wines, or meads by breaking down the pectin in the fruit so it doesn’t show up as a haze in your finished product.    To use, mix 2 tsp of pectic enzyme with cold water and add to 5 - 6 gallon of wort before the start of fermentation. Enzymes denature above 150° Fahrenheit (approximately) so only add them to your product after it has cooled.

Premium, Fire-Toasted Oak Cubes from Stavin Medium + Toast American Oak will impart flavors of campfire, vanilla, roasted coffee and butterscotch. These fire-toasted oak cubes are as close as you can come to the full range of flavors you would get from aging your beer in a full sized barrel, unlike convection-toased cubes. The difference is that convection toasted cubes are made by cutting the stave to size, then passing the small cubes through a toasting chamber. Stavin fire-toasts their staves whole, just like they would when making a barrel, and then cuts them down to size. The result is a gradation of toasting from the surface through to the center of the cube, where each different toast level represents a different flavor set that the oak will give your beer. The result is a much more complex and natural profile; by comparison convection toasted cubes taste one dimensional. Oak cubes also release their flavor into your beer more slowly than chips, giving you more control over the final degree of impact in your beer. You should plan on an extended aging period of 1-6 months when using cubes. This longer contact time again promotes flavor complexity by allowing all the flavors of the oak and your beer to marry. Recommended Dosage is 2 oz per 5 gallons for impact equivalent to aging in a brand new oak barrel. Click here for a PDF of the MoreWine Oak Cube Dosages.

Convection toasted Oak Cubes made in the US from American Oak. These Oak Cubes impart similar flavors as the equivalent oak type and toast level chip, but extract more slowly giving you more control over the final impact in your beer. These cubes are produced from staves of American oak that have been air-seasoned for 18-24 months, then toasted to a Medium Toast. They will add a sweet, butterscotch note with a hint of bourbon char to your beer. Suggested dosage is 2-4 oz per 5 gallons of beer.

Potassium Carbonate is used to lower acidity levels in wine. 3.8 grams per gallon will reduce acidity by about .1%. Potassium Carbonate requires that the fermenter be stored cold for several weeks after application (please see our guides to Cold Stabilization in the documents tab above). During the period of cold stabilization the tartaric acid drops out as potassium bitartrate. Doing a trial run with a small amount is strongly suggested to determine exactly what the drop in acidity will be. Calcium carbonate can be used in a similar manner and does not require cold stabilization. However it adversely affects flavor, takes month to precipitate out of solution, and preferentially reduces tartaric acid first before affecting malic or citric acid. A rough approximate of weight is 1 tsp = 8.3 grams. We highly recommend using a scale to weigh the product for an accurate dose. We do not recommend relying on these rough conversions for accurate dosage rates.

Ascorbic acid is a quick-acting and powerful antioxidant that is used in white winemaking to protect against light and short aerations, such as racking and bottling. It works by rapidly converting dissolved oxygen into hydrogen peroxide before it has a chance to react with oxidative enzymes and cause browning. However, this hydrogen peroxide itself needs to be removed from the wine in order to avoid the very phenomenon that was trying to be avoided in the first place, namely oxidizing the wine. The answer lies in always making sure that the free SO2 levels are correct, both before the ascorbic addition is to be made and after. (Note that "Titrettes" are not accurate enough for this, and that a more precise means of determing free SO2 is needed, such as an Aeration-Oxidation set-up). Addition rate is around 50 mg/l (ppm) as long as the free SO2 is maintained at 30 mg/l (ppm). A rough approximate of weight is 1 tsp = 3.2 grams. We highly recommend using a scale to weigh the product for an accurate dose. We do not recommend relying on these rough conversions for accurate dosage rates.

Due to high demand, the 55 lb is currently out of stock. Be the first to receive your items by placing a pre-order today. We will automatically ship this to you when we receive more inventory. 3.4g per gallon adjusts acidity by +.1%. It will lower pH less than will tartaric acid. Malic acid is the acid found in apples and is therefore the best choice for adjusting ciders.  Malic is less sour than tartaric acid and can also be used to make acid adjustments in Rieslings, Gewurztraminer, and Muscat varieties, though many winemakers still prefer to use tartaric acid in these situations. You would not want to add Malic acid to any wine that will undergo a malolactic fermentation. As a note: only half of the artificially added malic acid will convert to lactic acid during a malolactic fermentation. A rough approximate of weight is 1 tsp = 2.7 grams. We highly recommend using a scale to weigh the product for an accurate dose. We do not recommend relying on these rough conversions for accurate dosage rates.

Oak Chips are a fast and economical way to add oak barrel flavor to any beer. Oak Chips are made from seasoned American and French Oak staves which are chipped down and toasted to create flavors similar to what you'd get from a barrel. The available toast levels are Medium, Medium +, and Heavy. It's important to understand that each toasting level creates different flavors in the oak; not a greater intensity of impact in your beer. Don't think of them as weak, normal & strong; they're each a different flavor profile. These staves for these Medium Toast French Oak chips are sourced from a cooper (barrel maker) in Napa, CA. They deliver clove and spice flavors of medium intensity, along with strong flavors of Butterscotch & perceived sweetness. Because of the high surface area, oak chips can extract quickly and care should be taken not to overdo it. Taste your beer frequently after the first week of contact and be ready to rack off the oak chips. Suggested Dosage is 1-2 oz per 5 gallons.

Volclay KWK Krystal Klear Bentonite is a clay-like mineral with a negative charge that, similar to Sparkolloid, removes positively charged particles. It is most effective when the wine is at a warmer temperature, so we recommend using it for fining in late spring or early summer. It also works better at lower pH levels because proteins have a stronger positive charge in more acidic conditions.  Generic Low-Level Fining for 5 Gallons: Blend 1/2 tsp (about 3g) of bentonite with 1/2 cup of hot water (140 to 200°F) in a blender for 1-2 minutes. Let the mixture sit for 60 minutes, then stir it well before adding it to the wine. Allow the wine to stand for 10-14 days before racking off. This method achieves a fining rate of 0.16g/L. Generic Mid-Level Fining: Follow the same steps as above but use 9 grams of bentonite and 3/4 cup of hot water. This method achieves a fining rate of 0.5g/L. More Scientific Approach: You can create a 5% bentonite stock solution and run bench trials to determine the lowest effective concentration for clearing the wine. Since fining is non-selective, it removes both undesirable particles like yeast and some desirable phenolic compounds. Therefore, it's best to use the lowest effective concentration. To make a 5% solution, dissolve 50 grams of bentonite in 850ml of hot water, mix thoroughly, and top up with water to a final volume of 1L. Set up trials with clear jars of equal volume, adding varying amounts of the solution to achieve addition rates between 0.3g/L and 2.0g/L. You’ll need to do some calculations to determine the right amount for your needs. Let the trials clear overnight. For more detailed technical information, consult BK653 - Monitoring the Winemaking Process from Grapes to Wine - Techniques & Concepts. Fining with Wine Kits: When using a wine kit made from concentrate, bentonite is typically added on the first day for a few reasons. It serves as a nucleation site for CO2 removal. The CO2 movement helps distribute the bentonite throughout the wine, allowing you to use less and achieve effective fining in a shorter time.

Oak Chips are a fast and economical way to add oak barrel flavor to any beer. Oak Chips are made from seasoned American and French Oak staves which are chipped down and convection-toasted to create flavors similar to what a comparably toasted barrel would impart. The available toast levels are Medium, Medium +, and Heavy. It's important to understand that each toasting level creates different flavors in the oak; not a greater intensity of impact in your beer. Don't think of them as weak, normal & strong; they're each a different flavor profile. Heavy Toast American Oak chips will impart strong flavors of Vanilla & Char, with a small note of Clove. These chips will not impart the coconut flavor often characteristic of lower toast American oaks. Because of the high surface area, oak chips can extract quickly and care should be taken not to overdo it. Taste your beer frequently after the first week of contact and be ready to rack off the oak chips. Suggested Dosage is 1-2 oz per 5 gallons.

Cubes have a longer contact time than traditional chips do, which make them better for long-term aging of wines and beers. Also, longer contact time means longer extraction of flavors (3-6 months), which leads to a more complex combination of flavors. Chips are usually done giving flavor after a week, there by contributing a harsh, flat oak flavor. Our cubes are fires toasted and cut by Stavin, a leading supplier of high-quality oak alternatives to top commercial wineries.   Click here for a PDF of the MoreWine Oak Cube Dosages.

You should plan on an extended aging period of 1-6 months when using cubes. This longer contact time again promotes flavor complexity by allowing all the flavors of the oak and your beer to marry. Recommended Dosage is 2 oz per 5 gallons for impact equivalent to aging in a brand new oak barrel.

Lallzyme EX – Enzyme for Enhanced Color and Juice Release in Early-Drinking Red Wines Improves color extraction while preserving soft, approachable tannins Increases free-run and press juice yield by breaking down cell wall pectins Enhances clarification and reduces solids for easier pressing and settling Supports smooth mouthfeel in red wines intended for early consumption Balanced enzyme activity preserves varietal fruit while aiding extraction efficiency Lallzyme EX is a gentle maceration enzyme developed by Lallemand for red wine fermentations where balance, early drinkability, and clean extraction are key. Its primary function is to degrade grape skin cell walls through pectinase and hemicellulase activity, improving juice yield and the release of color compounds without promoting aggressive tannin extraction. This makes it particularly well-suited for light- to medium-bodied red wines or warm-climate varietals where managing tannin levels is critical. EX helps clarify must, improve press efficiency, and support the production of soft, fruit-driven wines that are ready for market sooner. Comparison to Other Lallemand Maceration Enzymes: Compared to EX-V, which targets tannin structure and aging potential, EX is better for fresh, youthful styles that prioritize fruit expression and roundness. In summary: EX = best for early-release reds, softer tannins, moderate color EX-V = ideal for structure and age-worthines Protocol Dilute Lallzyme EX in 10 times its weight of chlorine-free water. Add to crushed grapes or must at the start of fermentation. Mix well to ensure even distribution. Best activity between 20–30°C. Avoid use below 10°C or after fermentation is complete. Usage Rates Recommended dosage: 20–30 grams per ton of grapes = 0.44–0.66 grams per hectoliter (assuming 450 L/ton) = 0.0044–0.0066 grams per liter = 0.017–0.025 grams per gallon Use the lower range for softer grapes or longer macerations. Use higher rates when working with firmer-skinned varieties or short fermentations where improved extraction and juice yield are needed.

Oak Chips are a fast and economical way to add oak barrel flavor to any beer.  Oak Chips are made from seasoned American and French Oak staves which are chipped down and convection-toasted to create flavors similar to what a comparably toasted barrel would impart. The available toast levels are Medium, Medium +, and Heavy. It's important to understand that each toasting level creates different flavors in the oak; not a greater intensity of impact in your beer. Don't think of them as weak, normal & strong; they're each a different flavor profile. Heavy Toast French Oak chips will impart strong flavors of Clove, Spice, Smoke & Butterscotch; along with a small amount of Vanilla & Coconut flavor. Because of the high surface area, oak chips can extract quickly and care should be taken not to overdo it. Taste your beer frequently after the first week of contact and be ready to rack off the oak chips. Suggested Dosage is 1-2 oz per 5 gallons.

Lallzyme EX-V – Enzyme for Structured Red Wines with Enhanced Color and Tannin Stability Extracts color and tannins with improved integration for wines destined for aging Promotes stable anthocyanin-tannin bonding for long-lasting color Enhances mouthfeel, midpalate weight, and structural balance Improves juice yield and reduces solids through efficient cell wall degradation Balanced enzyme activity supports both extraction and finesse in premium red wines Lallzyme EX-V is a precision enzyme blend developed by Lallemand for red wine fermentations where structure, balance, and ageability are desired. It combines strong pectolytic activity with targeted cellulase and hemicellulase functions to break down grape skin cell walls, facilitating the release of anthocyanins and seed-derived tannins in a controlled, integrative manner. EX-V is ideal for varietals with moderate to firm skins or when crafting red wines intended for barrel aging, as it enhances phenolic complexity without over-extracting bitterness or astringency. Wines fermented with EX-V tend to show refined texture, vivid color, and excellent long-term stability. Comparison to Other Lallemand Maceration Enzymes: Compared to EX, which is best for early-drinking, fruit-forward reds, EX-V is designed for more structured, age-worthy styles with higher tannin and color stability.  EX = softer, fruit-driven reds for early release EX-V = structured, balanced reds with aging potential Protocol Dilute Lallzyme EX-V in 10 times its weight of chlorine-free water. Add to crushed grapes or must at the beginning of fermentation. Mix thoroughly for even dispersion. Optimal temperature range: 20–30°C. Avoid adding below 10°C or after alcoholic fermentation begins. Usage Rates Recommended dosage: 30–40 grams per ton of grapes = 0.66–0.88 grams per hectoliter (assuming 450 L/ton) = 0.0066–0.0088 grams per liter = 0.025–0.033 grams per gallon Use the lower end of the range for moderately structured fruit or extended maceration. Use the higher range for tighter-skinned grapes, shorter fermentations, or when greater phenolic extraction and color stability are required for barrel-aged or long-lived reds.
