Fermaid® K is a blended complex yeast nutrient that supplies ammonia salts (DAP), free amino acids (organic nitrogen derived from inactivated yeast), sterols, unsaturated fatty acids, key nutrients (magnesium sulfate, thiamin, folic acid, niacin, biotin, calcium pan­tothenate) and inactive yeast.For best results, Fermaid K should be used in conjunction with an appropriate yeast rehydration nutrient (such as Go-Ferm or Go-Ferm Protect) to assure proper nutrition of cultured yeast from rehydration through completed fermentation. Add 25 g/hL at 1/3 sugar depletion or in two doses; 12.5 g/hL at the end of lag phase and 12.5 g/hL at 1/3 sugar depletion.Fermaid K provides unsaturated fatty acids and sterols. These are important survival factors needed to maintain alcohol resistance and permease activity. They also help keep volatile acidity levels low.Nitrogen is needed 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.The cell wall fractions in Fermaid K absorb short and medium chain fatty acids that are toxic to the yeast. They also provide nucleation sites to help keep the yeast in suspension.To UseFermaid K should be mixed with room temperature water before adding to an active fermen­tation to avoid CO2 release and overflowing of tanks or barrels. The amount of water used is not critical. Simply add enough to make a slurry.StorageDated expiration. Store at 18°C(65°F). Once opened, keep tightly sealed and dry.Recommended Dosage1 g/gal    25 g/hL 2 lb/1000 gal

Whirlfloc® T kettle coagulant and fining agent is a purified, high molecular weight carrageenan powder extracted from Irish Moss algae, put in a convenient tablet form. It reacts with colloidal, haze promoting material in the wort to accelerate the formation of dense and compact trub during the hot and cold wort breaks. Whirlfloc binds with the trub and is removed with that material by settling or filtration before the beer is finished. It does not remain in the beer. This saves time, boosts wort recovery, and results in a brighter wort. Improved wort clarity with Whirlfloc T leads to cleaner fermentation and easier filtration afterward. Recommended Usage: For 5 gallons, add 0.2-0.4 tablets to the boiling kettle, 10 minutes before the end of boiling. Occasionally as much as a 1 full tablet is required, especially in low-pH brews.Tablets do not need to be hydrated and should dissolve rapidly. If problems occur, the tablet may be crushed prior to use.

Potassium Metabisulfite is a common additive used to preserve and stabilize wines, ciders, and occasionally beers. When added to wine or must, it forms sulfur dioxide gas (SO2). This prevents most wild microorganisms from growing and acts as a potent antioxidant, protecting both the color and delicate flavors of wine. Potassium Metabisulfite solutions are also used as sanitizing rinses for winemaking equipment. Recommended usage: Dosage varies when used to kill wild bacteria in must, halt fermentation, or preserve finished wines against oxidation. The addition of ¼ teaspoon of potassium metabisulfite to 5 gallons contributes approximately 50 ppm of free SO2. To make a sanitizing rinse for equipment, dissolve 8 teaspoons of potassium metabisulfite into 1 gallon of water. High concentrations of sulfur dioxide gas are irritating and toxic, so use in a well ventilated area. After applying the solution to your equipment, the items must be rinsed with clean, cold water.

Go-Ferm Protect is a new formulation of Go-FermGo-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.New Advanced Formula!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, over clarification 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 rehydration 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  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.To UseUse at a rate of 1.25 g Go-Ferm Protect per 1 g of yeast. A rough approximation of weight is 1 tsp = 3.2 grams. It is highly recommend using a scale to weigh the product for an accurate dose. It is not recommend relying on these rough conversions for accurate dosage rates.

Bentonite is a negative charged, clay-like mineral that removes positively charged particles. It works best when the wine is at warmer temperature so it is suggested clearing with bentonite in the late spring or early summer. It is also more effective at a lower pH because the positive charge on proteins is stronger at lower pH levels.  It is usually added prior to fermentation, sometimes during secondary.   When making a wine kit from concentrate you will often add the bentonite on the first day. This happens for a couple of reasons. It is used as a nucleation sites for the removal of CO2. Additionally, the bentonite is moved all around the wine by the CO2 making it more effective in a shorter time period.Generic low level fining for five gallons: blend 1/2 tsp (approximately 3g) with 1/2 cup of hot water (140 to 200 F) in a blender for 1-2 minutes. Let stand for 60 minutes, mix, and stir into wine. Let stand for 10-14 days and then rack off. This is fining at .16g/LFor a generic mid level addition: Follow above directions but use 9 grams of with 3/4 cup of water. This is fining at .5g/L.

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.

Scott’TanTM FT Rouge is a proprietary tannin specifically formulated for the North American market. It is a blend of highly reactive tannins derived from exotic woods and chestnut. The addition of FT Rouge at the beginning of red wine fermentation helps preserve the grapes’ natural tannins so they can combine with anthocyanins to create optimal stable color. Mouthfeel is also enhanced. FT Rouge provides anti-oxidative protection and will inhibit oxidative enzymes (such as laccase) associated with browning. To Use: Gradually sprinkle FT Rouge directly on grapes at the crusher or add to the must during a pump-over to obtain good homogenization. If subsequent additions of FT Rouge are desired, this can be done in increments of 0.5 lb/1000 gal (63 ppm) during pump-overs. If an addition of FT Rouge (or FT Rouge Soft) is made post-fermentation, we recommend waiting 3-6 weeks after the tannin addition before racking, fining, filtering or bottling. Storage: Dated expiration. Unopened the shelf life is 5 years at 18ºC(65ºF). Once opened keep tightly sealed and dry. Recommended for use with:  Red, Fruit Recommended Dosage: Red Vinifera Must: 200-500 ppm || 20-50 g/hL || 1.6-4.0 lb/1000 gal Red Non-Vinifera Must: 300-600 ppm || 30-60 g/hL || 2.4-5.0 lb/1000 gal Fruit: 200-500 ppm || 20-50 g/hL || 1.60-4.0 lb/1000 gal Tannin Source: Chestnut Hardwood FT Rouge Tannin additions are highly beneficial during rot management for red wines as they act as an antioxidant and help minimize the damage from laccase.

Wyeast Wine Nutrient Blend is a custom blend of vitamins, minerals, and micronutrients essential for an orderly and complete fermentation. During the cell growth and metabolization of sugars that takes place in every fermentation, yeast cells require an array of trace elements, vitamins, and compounds that can be assimilated from their environment in order to carry out their basic functions of life. However, honey-based fermentations are deficient in many of these nutrients. Nutrient deficiency can lead to disrupted or incomplete fermentations, off-flavors and aromas, and diminished stability of the finished product. Supplementing your must with Wyeast Wine Nutrient Blend helps ensure high viability and health of your yeast population, which in turn helps ensure a rapid, complete, and successful fermentation with repeatable results. Contents: Proprietary blend of vitamins, minerals, inorganic nitrogen, organic nitrogen, zinc, phosphates and other trace elements. Wyeast Nutrient Blend contains DAP (Diammonium Phosphate). Dosage Rate: 1/2 tsp (2.2 g) per 5 gallons (19 L) of must (unfermented mead) Usage Directions: Dissolve Wyeast Nutrient in warm water prior to adding to must. Divide total volume evenly, each portion to be added over several alternating days. Add to must after pitching yeast, and over the next several days as determined by your nutrient addition plan. Degassing between nutrient addition days may be necessary to prevent foaming over. Shelf-Life: 1 year if stored in airtight container in a cool environment Size: Available in 1.5 oz (42 g) tubes

For WineGelatin will help to reduce cloudiness by removing colloidal substances. It has an overall tannin polishing effect, but still preserves the phenolic compounds responsible for structure (similar to fining with egg whites). Add at the rate of .2 to .35 grams per gallon.Maximum clarification and filter-ability achieved after one week. If you will be ageing the the wine, a second racking one week after the first racking is recommended. Do not leave gelatins in wine more than 30 days.For BeerUse 1/2 tsp for five gallons of beer. Dissolve gelatin into 1/4-1/2 cup of hot water to dissolve and add to beer. Wait a few days and rack off.A rough approximate of weight is 1 tsp = 1.2 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.   Gelatin reacts with negatively charged compounds such as tannin in wines and juices thereby reducing astringency, bitterness and color. Gelatin also reacts with negatively charged colloidal silicon dioxide to form a dense coagulum with the destabilized silica, resulting in clarification. Wine and fruit juice processors benefit from the rapid clarification and improved filterability that are a result of co-fining with Gelatin and colloidal silica. 2 ounce package
