Abstract
The supply of oxygen to yeast for short periods during the fermentation of wort of high specific gravity can prevent excessive synthesis of ethyl acetate and isoamyl acetate, although it does not affect levels of higher alcohols. Oxygenation increases yeast growth and causes faster fermentation. The effect of oxygen on ester accumulation is independent of pitching rate.Keywords
