ABSTRACT:
The subject matter of the invention is a method for the production of low-alcohol or alcohol-free beer having a glycerol content of from 0.3 to 2.0% by volume, which content improves the body of the beer. In the method according to the invention, the process of fermentation is carried out using an ADH-negative yeast mutant which cannot produce alcohol, but produces increased amounts of glycerol instead. The obtained alcohol-free beer can be blended with normal, alcoholic beer to give low-alcohol beer.
