Alpha Amylase Enzyme can be used as a mashing aid to convert starches into simple sugars that are fermentable by brewing yeast. Not to be confused with gluco amylase, which breaks down carbohydrates, Alpha Amylase works with starches and is most often used in all-grain batches. Because you only use 1 tsp per 5 gallons, the 1-lb bulk size is ideal for those who produce large or frequent batches. We also have a 2-oz Alpha Amylase available.
Use 1 teaspoon per 5 gallons (5ml per 19L). 1 package is good for about 480 gallons.
