  • Process for the production of alcohol-free, yeast white beer
    Patent number: 4790993
    Abstract: Disclosed is an alcohol-free yeast white beer and a process for its production wherein the yeast is physically separated from an alcohol containing yeast white beer free of fermentable substances. The beer is then subjected to a vacuum distillation until the alcohol content has been reduced to less than 0.5% by volume to produce a beer concentrate. A corresponding amount of oxygen-free, carbonic acid-containing make-up water is added to the concentrate. Subsequently, top-fermented brewers' yeast is added in an amount above the content normally present in yeast white beer, and thereafter the product is stored at a temperature of from 0.degree. to 10.degree. C. Subsequently, yeast is again separated off and thereafter the desired amount of yeast and carbon dioxide is added.
