The invention relates to a simplified beer production process, which comprises the following steps of: (1) crushing malts; (2) saccharifying; (3) filtering wort; (4) boiling the wort and adding hops; (5) performing convolute deposition; (6) cooling the wort, and adding yeasts and processing in a pre-fermentor; (7) finishing pre-fermentation, and then processing in a post-fermentor; (8) finishing post-fermentation, and then processing in a fine rice wine pot; and (9) packaging the beer for sale. According to the simplified beer production process, no auxiliary material or chemical product is added in the production process of the beer, the fermentation period is prolonged through a low-temperature brewing technology, the generation of various higher alcohols is effectively reduced in the fermentation process, various process means for improving and prolonging the storage life are omitted, and various nutrient substances in the beer, which are beneficial to human bodies, are kept to ensure that the fresh taste of the beer is more obvious and is tasty, refreshing and pleasant.
