Is Coffee Acidic?

Coffee is generally considered an acidic beverage. The pH level of coffee typically ranges from 4.85 to 5.10, making it slightly more acidic than black tea (pH 5.00-5.50) and significantly more acidic than drinks like milk (pH 6.50-6.75) and orange juice (pH 3.30-4.20).

The primary contributors to coffee's acidity are chlorogenic acids, which account for about 75% of the total acids in coffee beans. Chlorogenic acids are composed of caffeic acid and quinic acid. In addition to chlorogenic acids, coffee also contains other acids such as citric, maleic, acetic, and phosphoric acids.

The type of coffee beans, roasting level, and brewing method can influence the acidity of coffee. Arabica coffee beans are typically less acidic than Robusta beans. Dark roast coffee tends to be less acidic than light roast coffee. And drip-brewed coffee is generally less acidic than espresso.

Some individuals may experience adverse effects such as heartburn, acid reflux, and digestive discomfort due to coffee's acidity. If you experience such issues, you may consider opting for low-acid coffee, cold brew, or adding a splash of milk or cream to neutralize the acidity.
