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. Using non-cereal sources also permits the simplified production of a gluten-free fermentation product that can be used in preparing beverages consumable by persons suffering from gluten intolerance.
