Patent number: 6033690Abstract: A process is disclosed for managing or controlling fermentation product profiles in a parallel pair of beer product streams in which a brewer's wort is fermented to produce a beer having fermentation products therein. The beer is passed along a first side of a semipermeable membrane, under selective fermentation product passing conditions, to transfer selected fermentation products across the membrane, and into an unfermented beer wort on a second side of that membrane. This procedure results in the production of an unfermented wort having a permeate-supplemented fermentation product profile and a fermented wort having a permeate-reduced product profile. The unfermented wort is then itself fermented to produce a second fermented wort. The second fermented wort has a combination of fermentation-supplemented and permeate-supplemented fermentation product profiles. The respective fermented worts are then finished and-packaged for subsequent distribution and consumption.Type: GrantFiled: October 7, 1997Date of Patent: March 7, 2000Assignee: Labatt Brewing Company LimitedInventors: Glen D.

Patent number: 4971807Abstract: A process for the production of beer with a low alcohol content is described. The process comprises preparing a wort by boiling and adding ascorbic acid to such wort prior, during, or after boiling, so long as the wort remains hot. The process can be employed according to the invention for the production of non-alcoholic beer by the yeast cold contact process, in which yeast recovered from a fermentation process is brought into contact with the wort at a low temperature below 0.degree. C. As a rule, the non-alcoholic beer produced by this process imparts an unpleasant and bitter aftertaste. By adding ascorbic acid to the boiling wort, the bitter aftertaste is completely eliminated.Type: GrantFiled: July 31, 1989Date of Patent: November 20, 1990Assignee: Brauerei FeldschlosschenInventors: Fritz Schur, Peter Sauer

Patent number: RE36897Abstract: A process for chill-treating, which is exemplified by a process for preparing a fermented malt beverage wherein brewing materials are mashed with water and the resulting mash is heated and wort separated therefrom. The wort is boiled cooled and fermented and the beer is subjected to a finishing stage, which includes aging, to produce the final beverage. The improvement comprises subjecting the beer to a cold stage comprising rapidly cooling the beer to a temperature of about its freezing point in such a manner that ice crystals are formed therein in only minimal amounts. The resulting cooled beer is then mixed for a short period of time with a beer slurry containing ice crystals, without any appreciable collateral increase in the amount of ice crystals in the resulting mixture. Finally, the so-treated beer is extracted from the mixture.Type: GrantFiled: March 31, 1999Date of Patent: October 3, 2000Assignee: Labatt Brewing Company LimitedInventors: Cameron R.
