Abstract:A new type of malus baccata beer was developed with the unique low temperature fermentation process of beer using malus baccata juice，wheat buds and barley malt as raw material.Through single factor experiment and orthogonal experimental were used sensory evaluation score as standard，the optimum technical conditions were obtained.The optimized fermentation conditions were determined as follows：addition ratio of wheat buds and malus baccata juice were 20 % and 10 % respectively，saccharifying temperature was 65 ℃，inoculum of beer yeast was 3.0%，fermentation at 15 ℃ for 5 days.Under these conditions，malus baccata beer was of not only the flavor characteristics of the beer，but also characteristics of malus baccata juice flavor.
