Preparation method of oak distillate

The invention discloses a preparation method of an oak distillate, which comprises the following steps: by taking single oak chips or mixed oak chips as raw materials, extracting by using an ethanol aqueous solution, filtering and collecting to obtain an extracting solution I, adding purified water for extracting, filtering and collecting to obtain an extracting solution II, combining and mixing the extracting solution I and the extracting solution II, distilling and collecting the distillate I by using a normal-pressure distiller, and drying to obtain the oak distillate. And carrying out reduced pressure distillation on the residual liquid, collecting distillate II, and combining the distillate I and the distillate II to obtain the oak distillate. The preparation process is simple, the efficiency is high, the obtained oak distillate is colorless and transparent, the oak fragrance is typical and pleasant, and industrial production and product application are facilitated. 本发明公开了一种橡木蒸馏液的制备方法，其以单一橡木片或混合橡木片为原料，先用
