The invention discloses a strain produced by screening beta-damascenone in Chinese liquor brewing by utilizing flavor directional technology and application thereof, belonging to the fields of biology engineering technology and brewing biotechnology. The beta-damascenone is an important trace characteristic flavor substance in Chinese Fen-flavor liquor. The strain is any one of Pichia anomala CGMCC4740, Issatchenkia orientalis CGMCC4741, Saccharomycopsis fibuligera CGMCC4742, Pichia farinosa CGMCC4743, Schizosaccharomyces pombe CGMCC4744, Trichosporon asahii CGMCC4746, Saccharomyces cerevisiae CGMCC4747, Kazachstania exigua CGMCC4748, Hanseniaspora osmophila CGMCC4749, Pichia fermentans CGMCC4750, Pichia membranifaciens CGMCC4751 and Clavispora lusitaniae CGMCC4752. The strain is obtainedby separating Daqu, Xiaoqu, fermented grains and brewing materials in the brewing environment of many famous wineries in China. The strain can be applied to the field of traditional food brewing and preparation of beta-damascenone biological spices.
