Fully caffeinated coffee is known to be acidic. Coffee lovers with digestive issues, such as acid reflux, may wonder if switching to decaf could be a less acidic option. That way, they could still enjoy their morning cup of java while reducing the chances of experiencing discomfort.
So, let's answer the question, "Is decaf coffee acidic?"
In short: Yes, decaffeinated coffee is acidic, but to a lesser degree than caffeinated coffee. Switching to decaf could be a great alternative for those with sensitive digestive systems, allowing them to enjoy a delicious cup of coffee while keeping their gut health in check.
Below, we go in depth into decaffeinated coffee, exploring what makes it acidic, how it affects the body, and some potential alternatives to try out.
At Mystic Monk Coffee, we offer a variety of delicious decaf coffees in different f blends and flavors, as well as specialty teas. Browse our selection or read on and learn more about decaf coffee.
How Is Decaf Coffee Acidic?
According to coffee expert Ryan Beckley, regular coffee has a variety of acids and organic compounds.
Some examples include:
- Chlorogenic acids
- Malic acid
- Citric acid
- Quinoic acid
- Phosphoric acid
On its own, coffee naturally has acidic properties.
Different Coffees Have Different Acidity Levels
Even though coffee beans are naturally acidic, that acidity breaks down as they are roasted. This means acidity levels vary among different coffee roasts.
Light roasts will be more acidic, giving them a brighter flavor and crisper texture. However, that also means a higher chance of causing heartburn or acid reflux.
Darker roast coffee beans are roasted longer at higher temperatures. This results in a less acidic profile, making it a possible alternative for those with sensitive digestive tracts.
Decaf Coffee Is Less Acidic
Decaf coffee has a lower acidity than regular coffee because the decaffeination process removes some acids, but not all.
On the pH scale, decaf tends to fall around 5 pH. With 7pH being neutral, this rating means that decaf coffee is acidic. Unfortunately, this acidity, though less than fully caffeinated coffee, may still upset certain stomach or digestive conditions.
Effects of Drinking Caffeinated Coffee

Even though it may be less acidic, decaf coffee is still coffee, meaning it can still have certain negative effects on your body. Whether it's the acidity or the small amounts of caffeine, it’s helpful to know how decaf coffee can affect your body and health.
Some things to consider when switching to decaf:
- Even with a small amount of acidity, decaf coffee can sometimes cause heartburn or symptoms of gastroesophageal reflux disease (GERD) if you have a more sensitive digestive tract.
- Research has shown that decaf could raise cholesterol levels, but further studies are needed to confirm.
- For those sensitive to caffeine, drinking decaf instead could lead to potentially unexpected cases of anxiety and jitteriness.
Overall, decaf coffee may still affect your stomach and mood. That said, there are still positive effects you can enjoy.
The Benefits of Drinking Decaf Coffee More Often
Here are some of the different benefits of drinking decaffeinated coffee:
- The National Coffee Association states that several organizational studies have found that drinking decaf (and coffee in general) may lower the risk of several different types of cancer, including liver, endometrial, mouth, pharynx, larynx, and skin cancers.
- Other studies have shown that drinking decaf regularly is linked to reducing the risk of developing type 2 diabetes.
- Drinking decaf instead of fully caffeinated coffee later in the day can reduce the likelihood of sleep disruption that is usually associated with drinking caffeine later in the evening.
Coffee in general is known to have a range of health benefits, and for the most part, that remains true for decaf coffee, too. But drinking it as an alternative could help if you are sensitive to acidic foods and beverages.
Low Acidic Coffee & Other Drinks to Try
Switching to decaf isn't the only way to enjoy a nice beverage and reduce acidity in your diet. Here are some more drinks that offer less acidic profiles:
- Darker roast coffees: As we mentioned earlier, darker roasts are less acidic. While it may still have caffeine, a decaf dark roast coffee has a delicious, bold, chocolatey flavor with less acidity than lighter roasts.
- Cold brew coffee: Since it's chilled and steeped longer, cold brew has less acidity and is easier on the stomach, reducing the risk of heartburn or acid reflux.
- Espresso: Made using darker roasts, which tend to be less acidic. Additionally, espresso is made under fast, high-pressure conditions, lowering the amount of acids in your brew.
- Herbal and green tea: Generally less acidic than coffee or black tea, herbal or green teas offer plenty of health benefits, including a small dose of caffeine (for green teas), and proving to be easy on sensitive stomachs.
