• Diammonium phosphate -- assists in fermentation, can help accelerate fermentation.
• Benzoic acid, and potassium and sodium salts of benzoic acid – prevents fermentation of sugar in wine being accumulated as distilling
material
• Carbohydrase (alpha-amylase, beta-amylase, glucoamylase, amyglucosidase) – converts starches to fermentable carbohydrates
• Copper sulfate – eliminates hydrogen sulfide and other sulfur compounds like mercaptan
• Hydrogen peroxide – reduces the bisulfate aldehyde complexin distilling material
• Potassium permanganate – oxidizing agent
• Ammonium phosphate -- assists in fermentation, can help accelerate fermentation
• Sodium hydroxide – acid neutralizing agent
• Sulfuric acid – effects yeast development in distilling material; prevents fermentation of sugar accumulated as distilling material; lowers
pH to prevent putrefaction and/or ethyl acetate development
• Defoaming agents (polyoxyethylene40 monostearate, silicon dioxide, dimethylpolysiloxane, sorbitanmonostearate, glycerol mono-oleate
and glyceryl dioleate) – controls foaming
• Malic acid -- added to boost acidity of wine.
• Acetaldehyde -- inhibits microbial growth and stabilizes the color of wine. Up to 300 parts per million used in treatment. up to .5mg per
liter allowed in finished wine.
• Tartaric acid -- added to boost acidity of wine.
• Silica Gel/Silicon dioxide -- used to filter and fine wine.
• Edible gelatin -- used to clarify and fine wine (remove sediments).
• Gum arabic -- used to clarify wine (remove sediments). Up to .24 grams per liter can be used for treatment.
• Aluminum silicates (bentonite or kaolin) -- used to clarify/fine wine.
• Miscellaneous filtration substances (diatomaceous earth, cellulose, etc.) -- used to filter wine.
• Polyvinyl-polypyr-rolidone -- used to modify color of wine, reduce tannins. Up to 7.19 grams per liter allowed for treatment.
• Activated charcoal -- used to filter wine and improve color. Up to 3 grams per liter allowed for treatment.
• Distilled alcohol -- used to fortify alcohol levels in wine.
• Cellulase -- enzyme that assists in the hydrolization of cellulose, a key process in fermentation.
• Protease -- enzyme that kills some bacterial agents and makes wine less heat-sensitive and less likely to throw sediment.
• Non-native Yeast -- required agent of the fermentation process, converts sugar from grapes into alcohol and lots of tasty flavors.
• Yeast cell walls -- bits of yeast cells that absorb anthocyanins (bitter tasting compounds) during red wine production and make the wine
smoother.

• Lactic bacteria -- used to reduce the acidity of wine.
• Potassium carbonate -- used to reduce the acidity of wine down to acid levels of 5 grams per liter only.
• Potassium bicarbonate -- used to reduce the acidity of wine.
• Calcium carbonate -- used to reduce the acidity of wine down to acid levels of 5 grams per liter only.
• Copper sulfate -- used to suppress bacterial growth, eliminate off odors. 6 mg per liter allowed for treatment. .5mg per liter allowed in
