Is Coffee Acidic?
Share
Coffee lovers often wonder — is coffee acidic? The answer is yes, coffee naturally contains acids, but the type and level of acidity varies 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 flavour, 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 or bright flavour, rather than causing stomach issues.
Which Coffee Beans Are Most Acidic?
-
African beans like Ethiopia Yirgacheffe G2 or Kenya Peaberry Coffee are naturally high in acidity, giving fruity and floral notes.
-
Central American beans like Costa Rica SHB Coffee often have medium acidity, with nutty and cocoa undertones.
-
South American beans like Brazil Yellow Bourbon are lower in acidity, offering smooth, creamy flavours.
How Roasting Affects Acidity
The darker the roast, the lower the perceived acidity:
-
Light roast – retains most of the natural acids, tastes bright and fruity.
-
Medium roast – balanced acidity, smooth flavour.
-
Dark roast – reduced acidity, more bitter and robust, like Italian Blend Coffee or Continental Blend Coffee.
Choosing the right roast can help if you have a sensitive stomach.
Brewing Methods and Acidity
-
Espresso – high pressure and short extraction; slightly lower acidity than drip.
-
Filter / Pour-over – highlights acidity, especially with light roasts.
-
Cold brew – much lower acidity due to slow extraction.
-
French press – medium acidity with full-bodied flavour.
For low-acid cold brew, try Frozen Amazon Coffee or Mayan Chill Coffee.
Health Effects of Coffee Acidity
Moderate coffee acidity is not harmful and can enhance flavour. However, high-acid coffee may cause:
-
Heartburn or acid reflux in sensitive individuals
-
Stomach discomfort if consumed on an empty stomach
Tips for reducing acidity:
-
Choose dark or medium roasts
-
Brew using cold or French press methods
-
Avoid adding too much sugar
Which Coffee Is Low-Acid?
If you prefer smooth, low-acid coffee:
-
Brazil Santos Good Cup Coffee – naturally smooth and creamy.
-
Colombia Excelso Huila Coffee – medium-bodied with mild acidity.
-
Uganda Robusta – bold with low acidity.
