Fermentation Rates of Grape Juice: V. Biotin Content of Juice and Its Effect on Alcoholic Fermentation Rate
AUTOR(ES)
Ough, C. S.
RESUMO
Microbiological analysis showed that juices from white grapes had less biotin than juices from red grapes. The biotin content of the juices of some varieties was significantly different from that of other varieties. We did not note any regional effects on the biotin content of the juices. Biotin content of the Cabernet Sauvignon grapes increased significantly with maturity, whereas the biotin content of a white variety did not. The biotin content, with the total nitrogen, can be used to estimate indirectly the yeast growth potential and hence to predict the fermentation rate of the juice. About 84% of the rate variation can be accounted for by the calculated regression equations.
