title: Accelerated Fermentation of Brewer's Wort by Saccharomyces carlsbergensis.
abstract: A rapid procedure for wort fermentation with Saccharomyces carlsbergensis at 12 C is described. Fermentation time was reduced from 7 to 4 days with normal inoculum by shaking. Increasing the inoculation to 5 to 10 times normal and shaking resulted in complete fermentation in 3 days. Maximum yeast population was reached rapidly with the large inocula, but fermentation proceeded at approximately the same rate when inoculations in excess of four times the normal were used. Similar results were obtained with both small-scale (100 ml) and microbrew (2.4 liters) fermentations.
