Is Coffee Acidic and Bad for Your Health?

It’s coffee o’clock somewhere! For hot beverage enthusiasts like me, my preferences include great quality of coffee beans to start my day. But, if you are hesitant because of the acidic effect of coffee, let’s learn more about it!

Actually, most coffee varieties are acidic, with an average pH value of 4.85 to 5.10. Among the countless compounds in this beverage, the brewing process releases 9 major acids that contribute to its unique flavor profile. Listed from highest concentration to lowest: chlorogenic, quinic, citric, acetic, lactic, malic, phosphoric, linoleic, and palmitic (3).

Several factors contribute to coffee’s acidity. The main ones are the roasting duration, brewing method, and fineness of the grind. Let’s talk about the three factors.

ROASTING

One study showed that the longer and hotter coffee beans were roasted, the lower their chlorogenic acid levels (4).

This suggests that lighter roasts tend to be higher in acidity, while darker roasts are lower.

BREWING

One study found that cold-brewed coffee was significantly lower in acidity than hot coffee (2).

Brewing time also appears to affect overall acidity, with a shorter duration resulting in a more acidic beverage and a moderate duration resulting in a less acidic one (5).

GROUND SIZE

The size of the coffee grounds can also affect acidity. The smaller the ground, the greater the surface area exposed relative to volume, which can lead to more acid being extracted in the brewing process (5).

Therefore, using a finer grind may result in a more acidic cup of coffee.

HEALTH EFFECT

While coffee’s acidity is fine for most people, it may aggravate certain health conditions in others.

These conditions include acid reflux, gastric ulcers, and irritable bowel syndrome (IBS). Alternatively, some people may benefit from simply opting for less acidic varieties.

Ways to reduce acidity

The acidity of coffee may be limiting for some. Here are a few ways to reduce it (10):

Remember that dark over light roasts are less acidic.
Learn to drink cold brew instead of hot.
Increase brew time, such as by using a French press.
Opt for a coarser grind.
Brew at a lower temperature.
