It can grow in wine containing up to 11% by volume of ethanol but cannot tolerate any free sulfur dioxide. Its optimum growth temperature is 20°C, and no growth is observed at 30°C. During growth on wine the yeast produces acetaldehyde, ethyl acetate, iso-amyl acetate, and an unidentified compound, the last being quantitatively the most important. The role of the yeast in wine spoilage is discussed and control procedures are given. ER -
