This invention belongs to the field of alcoholic beverage processing technology, specifically relating to a high-purity ginkgo wine and its preparation method. The preparation method comprises the following steps: ginkgo slurry undergoes preliminary enzymatic hydrolysis with neutral protease and amylase, followed by secondary enzymatic hydrolysis with pectinase and sodium bisulfite; brewing yeast fermentation broth is added for pre-fermentation; glutamine transaminase, *Saccharomyces cerevisiae* fermentation broth, and *Candida valerate* fermentation broth are added for post-fermentation; and finally, distillation and filtration are performed to obtain the ginkgo wine. This invention achieves complete decomposition and fermentation of ginkgo kernels through a two-step enzymatic hydrolysis and two-step fermentation process. The preparation method has advantages such as simple process and low cost, which is beneficial for industrial production; the prepared ginkgo wine has advantages such as clarity, strong aroma, high alcohol content, and low acidity.
