A method of producing a liquor, comprising the steps of feeding yeast to be fixed into a fluidized bed reactor equipped with a liquid circulation pipe and a gas exhaust port, supplying a brewing raw material liquid to the reactor, extracting a part of a culture liquid from the top of the reactor and returning the culture liquid into the bottom of the reactor. By this method fermentation is conducted while establishing circulation. Thus, a fluidized bed reactor filled with fixed yeast is used, fermented liquor in the reactor is circulated so as to move the fixed yeast. Accordingly, most of the carbon dioxide produced can be discharged outside the system without being dissolved in the fermented liquor. Moreover, amino acids in the brewing raw material liquid can be efficiently utilized by the yeast, so that the amino acid concentration in the product is low and the flavor is excellent. <IMAGE> |
