Influence of aeration conditions on acetaldehyde and diacetyl content in unfiltered beer
Annotation
Nowadays, despite lots of investigations, there is no single-valued answer on how atmospheric oxygen affects wort preparation. As to fermentation the answer is in the affirmative — aeration is indispensable to make for yeast growth, as well as good process of fermentation. The only question is what to aerate and when. As to this there are two opinions: either to aerate wort, or yeast, all investigations being done either in laboratories or in scale production. There are no data on small businesses.
