A method for the accelerated brewing of alcohol and alcoholic beverages including beer, wine, and spirits utilizing flavor producing strains of S. cerevisiae and/or other bacteria such as lactobacillus spp. and a high alcohol-tolerant strain of S. cerevisiae. Preferred strains of S. cerevisiae for the production of beer are ATCC Nos. 20866 and 20867. In the preferred method, the fermentation is conducted in a bioreactor containing the flavor-producing strains and the high alcohol tolerant strain of S. cerevisiae immobilized on inert, high surface area supports, preferably porous organic or glass beads. The bioreactor significantly decreases the fermentation time necessary to produce a beverage containing a desired alcohol percentage. For example, beer can be processed in less than about 12 to 18 hours, wine in less than about 36 hours.
A process for producing an alcohol solution comprising fermenting a sugar mixture with a strain of Saccharomyces cerevisiae which can tolerate alcohol concentrations of greater than 12% and sugar concentrations of greater than 20%, wherein said strain of S. cerevisiae rapidly ferments sugar substrates, producing alcohol at a rate of at least about 0.026 grams alcohol per hour per gram sugar per 10.sup.12 yeast cells.
