There is a demand for a beer-taste wort having less grain odor. The beer-taste wort has a ratio ((B)/(A)) of an original extract concentration (unit: mass %) (B) to an alcohol content (unit: (v/v) %) (A) of 2.50 or less.

Production of beer using a wort concentrate is described. In an embodiment, a system includes at least one fermentation tank comprising temperature control means. At least one processor configured to execute computer-readable instructions stored on at least one computer-readable storage media to perform a method of producing beer, including forming a mixture of a wort concentrate including hops and having a specific gravity of at least 1.085 kg/m3, with water and yeast in the fermentation tank, wherein forming the mixture comprises pumping the wort concentrate into the fermentation tank. The mixture is fermented and fermentation conditions monitored. On determining that predetermined fermentation conditions have been met, the fermented mixture is cooled to a temperature between zero and four degrees Celsius through controlling the temperature control means. The fermented mixture is carbonated, following addition of yeast finings, such that beer is produced.
