The present invention relates to a glycerol channel gene and its uses, specifically, a brewery yeast producing alcoholic beverages with excellent body and mellowness, alcoholic beverages produced using the yeast, a process for producing the alcoholic beverages. More particularly, the present invention relates to a yeast whose capability of producing glycerol, which contribute to body and mellowness of products, was controlled by controlling expression level of FPS1 gene encoding brewery yeast glycerol channel Fps1p, particularly non-ScFPS1 gene specific to lager brewing yeast, and to a method for producing alcoholic beverages with the yeast.
