Provided herein are a method for selecting a gene participating in the
desired brewing character and compiling a database of the whole genome
sequence of industrial yeast; identifying a gene participating in a
brewing characteristic from the database; functional analysis of the
gene; and a DNA array of the whole genome sequences of an industrial
yeast. Also provided are a method for yeast breeding; a method of
producing an alcoholic beverage with improved quality; and a screening
method to identify genes that increase productivity and/or improve flavor
in the production of an alcohol or an alcoholic beverage by (A) analyzing
a whole industrial yeast genome sequence, (B) comparing the genome
sequence with the genome sequence of S. cerevisiae, (C) selecting a gene
of the industrial yeast encoding having 70 to 97% identity to an amino
acid sequence of S. cerevisiae; and (D) analyzing the selected gene.
