Abstract
Abstract Beer having a low carbohydrate and a low alcohol content is prepared by a process involving the steps of partly fermenting a mixture containing wort, hops and yeast in a first main fermentation to an apparent degree of fermentation of 40 to 85 percent, reducing the alcohol content to about 1 percent by boiling, filtering, adding fresh yeast, carrying out a second main fermentation, adding a solution of diastase having a high content of marginal dextrinase which acts on alpha-1, 6 marginal dextrin after the second fermentation has begun and after completing the second fermentation clarifying to a produce a dietetic beer.

Claim 1
Independent Claim
177 words
A PROCESS FOR PRODUCING A DIETARY BEER HAVING A LOWALCOHOL CONTENT, A LOW-CARBOHYDRATE CONTENT AND A LOW-CALORIE VALUE COMPRISING: A. ALLOWING A MIXTURE CONTAINING WORT, HOPS AD YEAST TO PARTIALLY FERMENT IN A FIRST FERMENTATION STEP AT A TEMPERATURE OF ABOUT 4* TO 8*C FOR 2 TO 5 DAYS TO AN APPARENT DEGREE OF FERMENTATION OF ABOUT 40 TO 85 PERCENT; B. REDUCING THE CONTENT OF ALCOHOL IN THE PARTIALLY FERMENTED MIXTURE TO ABOUT 1 PERCENT BY BOILING; C. FILTERING THE PARTIALLY FERMENTED MIXTURE; D. ADDING FRESH YEAST TO THE PARTIALLY FERMENTED MIXTURE; E. ALLOWING THE PARTIALLY FERMENTED MIXTURE TO CONTINUE TO FERMENT IN A SECOND FERMENTATION STEP AT A TEMPERATURE OF ABOUT 12* TO 20*C FOR 7 TO 10 DAYS; F. CLARIFYING THE PARTIALLY FERMENTED MIXTURE AFTER THE SECOND FERMENTATION STEP HAS BEGUN; G. ADDING ABOUT 5 VOLUME PERCENT OF A SOLUTION OF DIASTASE HAVING A HIGH CONTENT OF MARGINAL DEXTRINASE WHICH ACTS ON ALPHA-1,6 MARGINAL DEXTRIN TO THE PARTIALLY FERMENTED CLARIFIED MIXTURE; H. ALLOWING THE CLARIFIED MIXTURE TO AGE; AND I. CLARIFYING THE FERMENTED MIXTURE.

Claim 3
Dependent Claim
34 words
A process according to claim 1 in which the first fermentation step is carried out until the mixture of wort, hops and yeast has undergone an apparent degree of fermentation of about 80 percent.
Claim 4
Dependent Claim
31 words
A process according to claim 1 wherein wort is added to the partially fermented mixture in an amount of about 100 percent by volume of the wort present in said mixture.
Claim 5
Dependent Claim
173 words
A process for producing a low-calorie, low-alcohol content, low carbohydrate dietetic beer comprising: a. partially fermenting a mixture containing wort, hops and yeast at a temperature between about 5* and 8*C for about 2 to 5 days to an apparent degree of fermentation of about 40 to 85 percent in a first fermentation step; b. boiling the partially fermented mixture until its alcohol content is reduced to about 1 percent by weight; c. filtering the partially fermented mixture; d. adding fresh yeast to the filtered partially fermented mixture; e. allowing the partially fermented mixture to undergo additional fermentation at a temperature of about 12* to 20*C for 7 to 10 days in a second fermentation step; f. adding about 5 volume percent of a solution of diastase having a high content of marginal dextrinase which acts on alpha-1,6 marginal dextrin after the second fermentation step has begun; g. allowing the partially fermented mixture to continue to ferment in a second fermentation step; and h. clarifying the fermented mixture to produce a dietetic beer.
Claim 6
Dependent Claim
173 words
A process for producing a low-calorie, low-alcohol content, low carbohydrate dietetic beer comprising: a. partially fermenting a mixture containing wort, hops and yeast at a temperature between about 5* and 8*C for about 2 to 5 days to an apparent degree of fermentation of about 40 to 85 percent in a first fermentation step; b. boiling the partially fermented mixture until its alcohol content is reduced to about 1 percent by weight; c. filtering the partially fermented mixture; d. adding fresh yeast to the filtered partially fermented mixture; e. allowing the partially fermented mixture to undergo additional fermentation at a temperature of about 12* to 20*C for 7 to 10 days in a second fermentation step; f. adding about 5 volume percent of a solution of diastase having a high content of marginal dextrinase which acts on alpha-1,6 marginal dextrin after the second fermentation step has begun; g. allowing the partially fermented mixture to continue to ferment in a second fermentation step; and h. clarifying the fermented mixture to produce a dietetic beer.
Claim 7
Dependent Claim
54 words
A process according to claim 4 wherein said solution of diastase is produced by mixing water with grits of malt at a temperature of about 45*C and thereafter allowing the grits of malt mixture to stand until a supernatant is formed having said high content of marginal dextrinase which acts on alpha-1,6 marginal dextrin.
Claim 8
Dependent Claim
