Amylase powder - 25gms Used to remove starch haze from the must of country wines. £2.15 Sorry, this item is currently out of stock. We are ordering weekly, but do not know when it will be available. Amylase is used to break down starch in a must into fermentable maltose and dextrin. In wine making if it is not added to a starch containing must, the finished wine will be cloudy.
