Includes bibliographical references. / The traditional batch brewing process is characterised by serial yeast propagation to build sufficient yeast for pitching. This results in cyclic variations in yeast environment, leading to a slow brewing process. In high gravity brewing the carbohydrate utilisation is inefficient as a result of the Crabtree effect that occurs in the presence of high sugar concentration. When optimising the brewing process the characteristics of conventional batch brewing should be maintained. Fed-batch propagation of yeast is used to improve carbohydrate utilisation and the yeast biomass formation by controlling nutrient supply.
