The invention discloses white spirit distiller grain yeast. The white spirit distiller grain yeast is prepared from, by weight, 30-50 parts of glucose amylase special for high-activity wine brewing, 30-45 parts of rhizopus bran, 5-15 parts of yeast starter, 1-10 parts of white spirit yeast, 1-6 parts of high-temperature-resistant and high-activity saccharomyces cerevisiae, 1-6 parts of high-activity aroma-producing yeast, 1-5 parts of whole-cell esterification yeast enzyme, 1-5 parts of acid protease, 1-5 parts of cellulase and 1-3 parts of medium-temperature alpha-amylase. The technology for adopting the distiller grain yeast for brewing comprises the steps of distiller grain cooling, distiller grain yeast mixing and smashing, distiller grain yeast activating, yeast discharging, fermenting in a tank and liquor steaming, substances such as starch, organic acid and alcohol remaining in white spirit distiller grain can be fully utilized for fermenting, the conversion rate is high, the wine quality is good, operation is easy, and the problems that the existing distiller grain white spirit brewing technology is low in conversion rate, few aromatic substances are generated, the wine quality is poor and the technology is complex are solved.
