Is Coffee Acidic?

Coffee lovers often wonder — is coffee acidic? The answer is yes. Coffee naturally contains acids, but the type and level of acidity vary depending on the bean, roast, and brewing method. Understanding acidity helps you enjoy coffee without digestive discomfort and choose the right blend for your taste.

What Makes Coffee Acidic?

Acidity in coffee comes from natural organic acids present in the beans. Common acids include:

  • Chlorogenic acid – contributes to bitterness and antioxidant properties.

  • Citric acid – gives a bright, fruity flavor, common in African beans.

  • Malic acid – creates a crisp, apple-like taste.

  • Quinic acid – develops during roasting, adding some bitterness.

Acidity is often perceived as a lively, bright flavor rather than the cause of stomach discomfort.

Which Coffee Beans Are Most Acidic?

African coffees are known for naturally high acidity, offering fruity and floral notes.
Closest US equivalents include:

Central American coffees such as Costa Rica beans typically offer medium acidity with nutty or cocoa undertones:

South American coffees like Brazilian beans tend to have lower acidity and a smooth, creamy flavor:

How Roasting Affects Acidity

The darker the roast, the lower the perceived acidity:

  • Light roast – retains most natural acids; bright and fruity.

  • Medium roast – balanced acidity and smooth flavor.

  • Dark roast – reduced acidity, bold and robust.

For dark, low-acid options, try:

Choosing the right roast can make a big difference, especially if you have a sensitive stomach.

Brewing Methods and Acidity

Different brewing methods extract acidity differently:

  • Espresso – lower acidity than drip due to quick extraction.

  • Filter / Pour-over – highlights acidity, especially with lighter roasts.

  • Cold brew – significantly lower acidity because of slow, cold extraction.

  • French press – medium acidity with rich body.

For smooth, low-acid cold brew, try:

Health Effects of Coffee Acidity

  • Acid reflux or heartburn

  • Stomach discomfort, especially on an empty stomach

Tips for reducing acidity:

  • Choose medium or dark roasts

  • Brew using French press or cold brew methods

  • Avoid excess sugar, which can increase stomach irritation
