Is coffee classified as an acid?
Yes, coffee is classified as an acidic beverage. The pH level of coffee typically ranges from 4.85 to 5.10, which is considered slightly acidic. This acidity is primarily attributed to the presence of chlorogenic acids, which are a group of polyphenols found in coffee beans. These acids are responsible for the characteristic tart and bitter flavors associated with coffee. However, it's worth noting that the acidity of coffee can vary depending on factors such as the type of coffee beans used, the roasting process, and the brewing method.
