What does 100 grain vinegar mean?

"100 grain vinegar" refers to a type of vinegar in Chinese cuisine. It is made by fermenting a mixture of 100 types of grains, typically including glutinous rice, sorghum, millet, barley, wheat, and brown rice, among others. The fermentation process involves culturing yeast and bacteria on the grains to convert the starch into alcohol and then into acetic acid, which gives vinegar its sour taste.

The resulting vinegar has a complex and rich flavor, with a variety of aromatic compounds that contribute to its distinctive taste and aroma. 100 grain vinegar is commonly used in Chinese cooking for a variety of dishes, including dumpling dipping sauces, noodle dishes, stir-fries, and marinades. It adds a tangy and slightly sweet flavor to dishes and is prized for its well-rounded taste.
