Does kawas contain alcohol?

Kawas in Xinjiang is a drink that many people like to drink. It is made of natural raw materials through natural fermentation. Because it is a fermented beverage, it also contains alcohol. However, the kawas level in Xinjiang is very low, generally only 0.3%. You can drive after drinking a little, but drinking a lot of Kawasaki in Xinjiang will also produce an alcohol reaction, leading to drunk driving. A traffic policeman measured kawas in Xinjiang. If you drink a large glass of kawas and blow immediately, the alcohol content in your blood reaches 86mg/ 100ml, which is obviously very high and has reached the standard of drunk driving. But after 5 minutes of testing, your blood alcohol content will drop to 0mg/ 100ml.
