Coffee is one of the most widely consumed beverages in the world. Yet, for some, making their favorite coffee a part of their morning ritual comes with acid reflux, heartburn, or other uncomfortable side effects.

If you once reveled in the beautiful aroma of a morning cup of coffee but suffered the consequences more and more, some bean options will allow you to enjoy your coffee without the unwanted peril that follows, and that includes a rich, dark roast coffee.

Someone who does not suffer adverse reactions from the acid levels in regular coffee may not think about the acidity in the beverage at all. However, if you suffer from gastrointestinal discomfort due to the harsh acids found in lighter roast coffee, it is most definitely something that comes to mind.

The pH of Coffee

The acidity of all consumable things is ranked on a pH scale:

  • A neutral pH is 7
  • Numbers below 7 are acidic
  • Numbers approaching 14 are alkaline
  • Regular medium roast coffee has a pH of about 5 (some lighter roasts are lower at 4.7)
  • Orange juice comes in at 3

The lower the pH number, the higher the acidity.

Acid is a scary word, especially when it comes to something you are putting in your body, but not all acids are created equal, and not all are bad for you. Some examples of coffee acids contributing to more prominent taste are:

  • Phosphoric and malic acids give the coffee a sweeter taste
  • Citric and acetic acid add a tart taste in low concentrations (too much makes coffee taste sour)
  • Chlorogenic acid will help with weight loss

Chlorogenic acid is what adds much of the acidity that coffee drinkers recognize. Regarding this acid in particular, the longer the bean is roasted, the more the chlorogenic acid breaks down, and it may have beneficial effects and help to settle your stomach rather than upset it.

There is a balance between too much and just enough acid. The right taste comes from the perfect balance.

Quinic acid is a less favorable acid that is produced as coffee quality degrades. This occurs when it is left for too long on a burner, and the acidic brew not only harms your stomach but gives off a nasty burnt smell with adverse effects. 

To avoid the burnt aroma and negative effects a harsh brew has on your digestive system, invest in a coffee carafe to keep your coffee warm to maintain optimal flavor, rather than leaving it on the warmer.

Coffee Bean Roast and Acidity

The roast of a coffee bean affects the level of caffeine and the acidity content. The darker the coffee roast, the lower the acidity since the roasting process burns off the acid content. 

The method by which the coffee is brewed will also affect the bean’s acidity. For example, one study found that coffee brewed with the cold brew method was lower in acidity than coffee prepared in a coffee press or using other hot brew methods.

The hot brewed coffee had a higher concentration of titratable acids and more significant antioxidant production than cold brews. It was noted that the titratable acid and antioxidant activity was poor in hot brewed coffee, concluding that hot brewed coffee extracts greater non-deprotonated acids compared to cold brews.

Final Word

When choosing the right coffee, remember that the higher the pH number, the lower the acidity levels. There is no such thing as acid-free coffee, and the darker the bean, the lower the acid content will typically be.

Even those who suffer from delicate stomachs are likely to find a wide range of gourmet coffees on the coffee market with an authentic coffee taste that they can enjoy. Keep in mind that roasts and coffee preparation help play a part in how much acidity the beverage will have. Light roast coffee grounds create acidic coffee. Dark roasts reduce the acidity of coffee.
