ABSTRACT:
A novel technique is provided for drying a yeast for brewing and a method of producing alcoholic beverages by using the yeast. It is intended to provide a method of producing a dry yeast which has the optimum fermentability when directly used in fermentation and gives an appropriate flavor without needing prepropagation, and a method of producing alcoholic beverages by using the yeast.A method comprising incorporating a stabilizer such as trehalose into a yeast which has been recovered from the fermentation step, and, if desired, further incorporating glycerol into the yeast to thereby lower the water activity in the cells, and then dehydrating/drying the yeast while sustaining a high viable cell ratio and favorable fermentability; and alcoholic beverages produced by using the yeast.
