Which coffee is low in acid?
Darker roasts, espresso, and cold brew. Beans from lower altitudes (Brazil, Sumatra) are naturally lower in acid. Slow drum roasting breaks down acids better than fast industrial roasting. The brewing method also influences acid levels.
Why that is
Acid in coffee isn't just one thing. In the specialty scene, acidity is a mark of quality—a bright, fruity acidity makes a good coffee exciting. If you prefer coffee with little acidity, there are several levers. The question is: what can you change?
Acid and origin:
- Lower altitudes (below 1,200 m) produce beans with less acid. Brazil, Sumatra, India, and Java are typical examples.
- Higher altitudes (1,500–2,200 m)—Ethiopia, Kenya, Colombia—create more complex acid profiles. Great flavor, but not for anyone who prefers little acidity.
- Robusta usually tastes less fruity and tart than Arabica, but contains more chlorogenic acid.
Acid and roasting:
- Light roast: Preserves the bean's natural acids—desired in specialty coffee, but not to everyone's taste.
- Medium roast: Reduces acidity, maintains complexity.
- Dark roast: Breaks down most of the chlorogenic acids. Less complex, but noticeably less acidic in taste.
- Drum roasting vs. industrial roasting: Slow drum roasting (12–20 minutes) breaks down acids gently. Industrial hot-air roasting (2–5 minutes) roasts the bean dark on the outside but not all the way through—leaving aggressive acids intact.
Acid and brewing method:
| Method | Acid level |
|---|---|
| Cold Brew | Very low |
| Espresso | Low to medium |
| French Press | Medium |
| Filter coffee (dark) | Medium |
| Pour-Over (light) | High |
| AeroPress | Variable (depends on temperature) |
Terminology: "Low-acid" on packaging usually refers to a lower content of chlorogenic acids, not the pH level. The pH level of coffee is generally around 4.8–5.1—similar to beer.
In practice at Green Wall Coffee
At Sophienstraße 27, our house espresso Dark & Twisty is a blend from Ethiopia, Brazil, Colombia and Peru, medium roasted, with chocolate and caramel. For guests who want to avoid acidity, I recommend it.
