Abstract: A method of producing a liquid fermentation product using a natural protein concentrate from a non-cereal grain source in place of protein derived from malted grains is provided. The natural protein concentrate can be directly used, in addition with a carbohydrate source, to produce a wort suitable for fermentation, thus avoiding the malting and mash mixing steps in traditional brewing methods. The wort requires less yeast to initiate the fermentation process than in similar alcohol fermentations, and does not require the addition of yeast nutrients. The resulting fermentation product can be processed for bottling without the need for an intervening storage period. The protein concentrate used in the method can be derived from non-cereal sources such as peas, soy, rice potatoes and other sources of natural protein.

Abstract: A method of producing wort or beer which avoids or minimizes problems encountered with high beta glucan content such as slow lautering of wort, slow filtration of beer, decreased yields, gel precipitations in the package, unfilterable beer haze, and colloidal instability. This method involves modifying the malt to an extent which reduces the beta glucan content to a sufficiently low value such that these problems are avoided or minimized sufficiently. An undesirable side effect of malting to this extent is that certain undesirable constituents, such as color components (causing the beer to be dark) and certain proteins, are formed. An adsorbent is contacted with the wort or beer to remove these undesirable constituents from the wort or beer. The adsorption step preferably utilizes clay, such as montmorillonite or bentonite, that can be readily filtered.
