The present invention relates to a brewing yeast with controlled hydrogen sulfide-producing ability, a method for producing an alcoholic beverage with a controlled amount of hydrogen sulfide. More particularly, the present invention relates to a yeast, wherein the hydrogen sulfide-producing ability to increase the fragrance of a product is regulated by enhancing the expression level of the YGR012W gene encoding brewing yeast cysteine synthase Ygr012wp, in particular the non-ScYGR012W gene specific for lager brewing yeast, And it relates to a method for producing an alcoholic beverage using the yeast. |
