Abstract:The fermentation technology of chestnut flower beer was studied with chestnut flower extract and malt as main materials. Through the orthogonal experiment，the production parameters of chestnut beer were optimized，and the chestnut beer was brewed by combining the traditional malt beer fermentation technology.The results showed that the optimum fermentation conditions of chestnut flower beer were as follows：the input amount of 5%chestnut flower extract was 10.0 mL，adding chestnut flower extract at inoculation stage and main fermentation temperature at 15 ℃. Chestnut flower beer fermented under this condition had the best flavor and taste.
