At present, the vinegar drinks on the market are mainly apple cider vinegar, and apple cider vinegar is mostly blended with apple juice. There are few vinegar drinks that are actually brewed. There is no literature report on the brewing of beverage vinegar with Anli as raw material. As a very characteristic fruit, Anli is mainly concentrated along the Great Wall in the east of Jingdong, with an annual output of 200,000 tons. However, the processing rate of Anli is only 4.7%. If an pear is used as raw material to brew an pear vinegar drink, it will not only contribute to the market, but also promote the formation of an pear industrial chain, improve the level of agricultural industrialization and farmers' income.
