Low-Acid Coffee: What It Is and How to Brew
Low-acid coffee can be a good option for people who like coffee but are sensitive to the acidity. It’s a smoother, gentler beverage, with the same coffee flavor.
What is low-acid coffee?
Low-acid coffee is coffee that has been specially grown, roasted, and brewed to reduce its acidity. Coffee that has 50% less acidity than regular coffee is considered “low-acid.”
Reducing the acidity of coffee can happen a few different ways, to create coffee that is easier on the stomach and teeth.
Acid vs. acidity in coffee
The term “acid” refers to the actual pH level of the coffee. The pH scale goes from 0 to 14, and coffee generally comes in at level 5. Low-acid coffee has a higher pH, making it less acidic.
Just to confuse matters, the term “acidity” is often used by coffee snobs to refer to the “brightness” or the tangy, lively flavor notes.
Low-acid coffee reduces the actual acidity, without necessarily eliminating the bright, pleasant flavors.
Roasting and growing low-acid coffee beans
Roasting techniques play a significant role in reducing the acidity of coffee beans. Low-acid coffee beans are roasted longer, over a lower heat. The slow-and-low method lets flavors develop in the beans, but also breaks down more acidic compounds.
And yes, that means dark roasts are typically lower in acidity, because they roast longer.
Additionally, beans grown at lower altitudes tend to be naturally lower in acid. Robusta coffee beans, for example, are grown at lower elevations. Low-elevation coffee also tends to be grown in:
- Cameroon
- Cote D’Ivoire
- Madagascar
- Tanzania
- Uganda
Brewing low-acid coffee
Different brewing methods can also impact the acidity of coffee. Cold brewing is an excellent method for reducing acidity, as the extended steeping time in cold water extracts fewer acidic compounds. Coffee made in a French press or an AeroPress can be lower-acid, because of the coarser grind that’s usually used and the shorter brewing time required. If you’re using a drip machine, set a lower brewing temp.
Low-acid coffee FAQ
Is low-acid coffee better for you?
The lower level of acidity can be a welcome break for people with acid reflux, sensitive stomachs, or dental issues. It’s less likely to cause discomfort or irritation.
Is decaf coffee low-acid?
Decaf is not necessarily low-acid. Decaffeination removes caffeine, of course, but does not significantly impact the pH level. But you can find low-acid, decaf coffee beans on the market.
Does low-acid coffee really taste the same?
Beauty is in the eye of the beholder. Some people say yes. Some say no. If the acidity of coffee bothers your guts, it’s worth a try!
