Last year, I spoiled a batch of beer without knowing anything about Diastatic Power. :cry: Instead of 53 bottles of Weissbier, I got 5 gallons of Weissbier Malt Vinegar. :? I have since educated myself with this web article: http://beersmith.com/blog/2010/01/04/di ... your-beer/ . :ugeek: I request that you incorporate a Diastatic Component into the Brewer's Friend Beer Calculator so that Homebrewers do not repeat my mistake.
