Abstract
Beer is brewed by a method in which a malted grain is combined with starch from a barley variety characterized by containing starch granules which are self-liquefying and produced by cross-breeding a first barley variety characterized by a hulless gene, n n on chromosome 1 and a second barley variety which is characterized by a waxy endosperm gene wx wx on chromosome 1.
Claims5
In a method for brewing beer by forming a malted barley grain, mixing said malted grain with a starch source, yeast and other beer brewing ingredients to form a brewery liquor and allowing said mixture to ferment until a wort is obtained having an ethyl alcohol content characteristic of beer, the improvement which comprises:
- mixing said malted grain with a cross-bred barley variety having a pedigree of `Waxy Oderbrucker`/7* `Compana`/2/`Sermo`/7*`Compana`, F.sub.4 and designated as Washonupana and containing strch granules which are self-liquefying in that the starch granules contain a high amount of .alpha.-amylase which is tenaciously bound to the starch granules such that said .alpha.-amylase degrades the starch in said granules to maltose, glucose and small fractions of .alpha.-limit dextrins wherein said self-liquifying starch granules are present in amounts ranging from 10 to 75% in said brewing liquor.
