Abstract
Process for the preparation of a sweet wort from a cereal, in which previously mashed cereal flour is mixed with a hydrolyzing substance introducing enzymes to undergo a saccharification treatment. Before mashing, the cereal flour is subjected to a cooking-extrusion at a temperature above 100.degree. C., by passage continuously in a screw-extrusion machine provided with heating means. The amount of water can be limited to that necessary for the bursting of the starch grain. The extruded cereal is then mashed and mixed with the hydrolyzing substance to undergo saccharification, and the latter can then be effected by infusion. The invention is especially applicable to the preparation of beer or of alcoholic beverages by fermentation of the sweet wort obtained.
