Does Organic Coffee Have Acid in It? The Surprising Truth

•
4 min read

According to a 2018 study in Scientific Reports, the average pH of brewed coffee falls between 4.85 and 5.4, making it naturally acidic. Does organic coffee have acid in it just like its conventional counterpart? The simple answer is yes, because acidity is an inherent trait of the coffee bean itself, regardless of how it was farmed.

Quick Summary

All coffee contains natural acids, and organic certification does not eliminate them. A coffee's acidity level is primarily influenced by bean type (Arabica vs. Robusta), roast level, brewing method, and processing, not whether it is organic. These factors determine the final concentration of organic acids in the brewed cup.

Key Points

  • Organic Certification Doesn't Remove Acid: Organic coffee contains acid just like any other coffee, as acidity is a natural component of the coffee bean itself.

  • Acidity Comes from the Bean, Not Chemicals: The acidic compounds in coffee, such as Chlorogenic Acid, are naturally present in the coffee plant, not a byproduct of conventional farming.

  • Roast Level is Key: Darker roasts break down acidic compounds, resulting in a lower-acid brew, while lighter roasts retain more acidity for a brighter flavor.

  • Brewing Method Matters: Cold brewing is a proven method for reducing acidity, as the process extracts fewer acidic compounds than hot water brewing.

  • Bean Type Influences Acidity: Arabica beans typically have less acidity than Robusta beans, which contain higher levels of Chlorogenic Acids.

  • How to Find Low-Acid Coffee: To reduce acidity, look for dark roast, organic Arabica beans from low-altitude regions like Sumatra, or use a cold brew method.

  • Flavor vs. pH Acidity: In coffee tasting, 'acidity' often refers to a bright, crisp flavor, which is different from the quantifiable pH level that can cause digestive issues.

The Science of Acidity in All Coffee Beans

Coffee's acidity is often misunderstood. It's a complex characteristic derived from the bean's natural composition, not an external chemical added during processing. Green (unroasted) coffee beans are naturally rich in various organic acids, with Chlorogenic Acids (CGAs) being a major component. These acids are crucial to developing the coffee's flavor profile but can also cause stomach irritation or heartburn for sensitive individuals.

When a coffee bean is roasted, these organic acids undergo a transformation. Some break down, while others are created. The roast level is one of the most significant factors in determining the final acidity of your cup. For instance, a light roast will have more CGAs, resulting in a brighter, more acidic flavor profile. As the roast deepens, these acids break down, producing a less acidic, smoother-tasting coffee. The organic versus conventional label simply doesn't play a role in this chemical process; it only refers to the farming practices used to grow the coffee cherries.

How Organic Farming Impacts Coffee, But Not Acidity

Organic coffee is grown without synthetic fertilizers or pesticides, adhering to strict certification standards. This farming method offers environmental benefits and ensures a cleaner product, free of potentially harmful chemical residues. However, it does not fundamentally change the coffee plant's biology or the genetic makeup of the bean itself, which is the source of all coffee's acidity. An organic Arabica bean will have the same foundational acidic compounds as a conventional Arabica bean of the same variety and origin. The differences in a coffee's final pH level are dictated by what happens after the beans are harvested, not the farming method.

Factors That Truly Affect Coffee's Acidity

If the organic label isn't the key to finding a low-acid cup, what is? Several critical factors influence the acidity of your morning brew.

  • Bean Type: Arabica beans are generally less acidic than Robusta beans, which contain higher levels of CGAs.
  • Roast Level: As mentioned, darker roasts reduce acidity by breaking down acidic compounds. A dark roast will almost always be less acidic than a light roast, regardless of whether it's organic.
  • Brewing Method: Cold brewing significantly reduces acidity because the longer, cooler steeping process extracts fewer acidic compounds. Hot brewing methods, especially drip coffee, tend to extract more acid. A French press also produces a less acidic cup than a standard drip machine.
  • Processing Method: How a coffee bean is processed after harvesting also plays a role. Washed processing can result in a brighter, more acidic cup, while natural or honey-processed beans often have lower acidity due to the fermentation process.

Comparison Table: Factors Influencing Coffee Acidity

Factor Effect on Acidity Reason
Roast Level (Dark) Lower Longer, hotter roasting breaks down acidic compounds like Chlorogenic Acid (CGA).
Roast Level (Light) Higher Shorter roasting retains more CGA, leading to a brighter flavor.
Bean Type (Arabica) Lower Naturally contains fewer CGAs compared to Robusta.
Bean Type (Robusta) Higher Contains significantly more CGAs than Arabica.
Brewing (Cold Brew) Lower Steeping in cold water for long periods extracts fewer acidic compounds.
Brewing (Hot Brew) Higher Hot water extracts acids more efficiently, leading to a higher concentration.
Processing (Natural) Lower Fermentation with the cherry pulp can reduce acidity.
Processing (Washed) Higher Pulp is removed before drying, resulting in a cleaner, more acidic profile.

How to Find a Low-Acid Organic Coffee

If you are specifically seeking a less acidic organic coffee, the organic label alone is not enough. You must look for other indicators on the packaging. Your best bet is to find an organic coffee that is also a dark roast, as the roasting process is the most effective way to reduce acidity. Alternatively, choose an organic bean that is naturally low in acid, such as those from Sumatra or Brazil, which are typically grown at lower altitudes. Finally, using a cold brew method at home will provide a less acidic experience with any organic coffee.

Conclusion: Organic is Not a Guarantee of Low Acidity

The notion that organic coffee is inherently less acidic is a common misconception. While organic practices are better for the environment and result in a purer product, they do not remove the natural acidic compounds found in all coffee beans. The acidity of your coffee is primarily controlled by the bean varietal, roast level, and brewing method. By paying attention to these factors, you can find a delicious, low-acid organic coffee that is also gentle on your stomach. Remember, a coffee's pH level is not a function of its organic certification but rather the result of its journey from farm to cup.

Frequently Asked Questions

No, organic coffee is not naturally less acidic. Acidity is an inherent property of all coffee beans, regardless of how they are farmed. Organic certification ensures the beans are grown without synthetic chemicals, but it does not remove the naturally occurring organic acids.

The main factors influencing coffee acidity are the bean type (Arabica vs. Robusta), the roast level (darker roasts are less acidic), the brewing method (cold brew reduces acidity), and the processing method (natural processing can result in lower acidity).

Arabica beans generally have a lower acid content than Robusta beans. Beans from lower-altitude regions, such as Brazil or Sumatra, also tend to have less acidity.

To reduce the acidity of your organic coffee, choose a dark roast, use a cold brew method, or try a French press. These methods all minimize the extraction of acidic compounds from the beans.

Yes, cold brewing significantly reduces the acidity of all coffee, including organic coffee. The process extracts fewer acidic compounds than hot water, resulting in a smoother, less acidic cup.

Flavor acidity refers to the bright, crisp, or tangy taste notes in coffee, which are desirable for a vibrant flavor profile. pH acidity, measured on a scale from 0-14, is the chemical measure of acid concentration, which can cause stomach upset for some people.

Yes, a dark roast organic coffee will be less acidic than a light roast organic coffee. The longer roasting process breaks down the chlorogenic acids that contribute to acidity, regardless of the bean's organic status.
