Acetic acid is a type of organic acid that has a sour taste and a pungent smell. It is present in many foods and beverages, including coffee.
In coffee, acetic acid is formed during the fermentation and roasting process. It is one of several compounds that contribute to the overall flavoor and aroma of coffee.
High levels of acetic acid can give coffee a vinegar-like taste, which is considered a defect in the coffee industry. However, in proper balance, it is said to provide notes of lime and sweetness.
