A heat soluble, commercial quallity extra no. 1 grade, powered Gelaitin. This is much higher quality Gelatin than you will find in most beer/winemaking shops. It is composed of high molecular weight mass proteins that carry a big positive charge. Prepare by mixing in warm water and then adding during a transfer or pump-over. The solution must be maintained at 95-104F (35-40C) when used. See below for different dosage rates for beer and wine.
Gelatin 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.
