Is Coffee Acidic?
Share
Coffee lovers often wonder — is coffee acidic? The answer is yes, but acidity isn’t necessarily a bad thing. Coffee naturally contains organic acids that shape the flavor and brightness of your brew. Understanding what acidity contributes to coffee helps you choose beans that match your taste and avoid digestive discomfort.
What Makes Coffee Acidic?
Acidity in coffee comes from natural organic acids found in the beans. These compounds determine the acidity level, which affects the flavor profile and overall experience.
Key acids include:
-
Chlorogenic acid – contributes to bitterness and antioxidant benefits.
-
Citric acid – responsible for fruity brightness, especially in African coffees.
-
Malic acid – gives a crisp, apple-like quality.
-
Quinic acid – develops during roasting, adding some bitterness.
Most high-quality Arabica beans naturally contain more nuanced acidity than Robusta beans, which is why Arabica is preferred for specialty coffee.
Coffee’s acidity also sits on the pH scale at around 4.5–6, meaning it is mildly acidic but far less acidic than orange juice, soda, or vinegar.
Which Coffee Beans Are Most Acidic?
Different origins and bean types produce different acidity levels. Several factors affect acidity, including climate, soil, and bean variety.
High Acidity Coffees (African Origins)

How Roasting Affects Acidity
Roast level is one of the biggest factors that affect acidity:
-
Light Roasts – Higher acidity, retaining most natural acids.
Try Blonde Roast Coffee Beans for a bright, lively cup. -
Medium Roasts – Balanced acidity and smoothness.
Breakfast Blend Coffee is a great all-rounder. -
Dark Roasts – Lower acidity because longer roasting breaks down acids.
Lower-acid darker roasts include:

Brewing Methods and Acidity
Your brewing method can significantly affect acidity extraction:
-
Espresso – Lower acidity due to rapid, pressurized extraction.
Try African Espresso Coffee. -
Filter / Pour-over – Highlights acidity, especially in light roasts.
-
Cold Brewing – One of the lowest-acidity brewing methods because cold water extracts fewer acids.

French Press – Produces a rich, full-bodied coffee with moderate acidity.
Health Effects of Coffee Acidity
Moderate acidity isn’t harmful, and in fact, acidity contributes significantly to coffee's flavor and complexity.
However, people with sensitive stomachs may experience:
-
Acid reflux
-
Heartburn
-
Stomach discomfort, especially on an empty stomach
Tips to Reduce Acidity:
-
Choose medium or dark roasts
-
Brew with cold water for cold brew
-
Try Arabica beans, which have smoother acidity
-
