Breeding of Yeast Strains with Good Diacetyl Reducing Capacity for Beer

Yeast strains on the production field were screened and cultured by diluting culture of microorganism to obtain the strain with good di-acetyl reducing capacity.The fermenting power of such strain was analyzed and the tasting of product beer fermented by such strain was per-formed.The results indicated that the use of such strain in beer production could achieve ideal effects and improve beer flavor stability.
