Fruit vinegar drinks are refreshing and healthy beverages popular in Taichung. They are made by fermenting fruits like apple, pineapple, or passion fruit with vinegar. The resulting drink is tangy, slightly sweet, and packed with vitamins and antioxidants. Fruit vinegar drinks are often served over ice and can be enjoyed as a thirst-quenching drink on a hot day. They are a great alternative to sugary sodas and are widely available in Taichung's markets and cafes.
