Can You Modify Yeast Enzymes?

Question

I was wondering whether anybody had experience with using fermentation modifying enzymes?

Where I live, it’s already 86+ (Fahrenheit) days and its not even summer yet, so doing a lager is out of the question.

I was wondering whether using an ale yeast and an enzyme to help it ferment out more completely might achieve a beer closer to a lager taste. Namely something more “refreshing” with a lighter body. Or is it just going to taste completely different??

Answer

Brewing a super low ester beer at high fermentation temps could be tough.

One way to “dry out” a fermentation is to add an adjunct sugar such as dextrose during or just after maximum krauzen. If added initially, simple sugars may “corrupt” the yeast by making it more difficult for them to ferment the complex stuff.
