| Abstract: | The use of carbohydrate adjuncts such as sucrose, fructose and glucose in brewer's wort significantly modifies the initial wort sugar spectrum and also the pattern of sugar uptake during fermentation by a strain of Saccharomyces uvarum (carlsbergensis). Under these conditions, the concentration of glucose and fructose in the wort was observed to increase when compared to worts in which corn starch was employed as an adjunct and glucose was taken up at a faster rate than fructose. The increase in glucose concentration in the wort also resulted in severe repression of maltose and maltotriose utilization with significant levels of these sugars remaining in the beer produced. |
