Internet Asks: "Is Coffee Acidic?"

Coffee is a popular drink worldwide, known for its energizing effects and unique flavor. However, many coffee drinkers wonder whether their daily cup of joe is too acidic for their health. In this article, we'll explore the acidity of coffee, its pH levels, and what effects it may have on the body.



Understanding acidity and pH levels

The acidity of a substance is determined by its pH level, which is a measure of how acidic or basic (alkaline) it is. The pH scale ranges from 0 to 14, with 0 being the most acidic, 14 the most alkaline, and 7 neutral. Substances with a pH below 7 are considered acidic, while those with a pH above 7 are alkaline. For example, lemon juice has a pH of around 2, which means it is highly acidic, while baking soda has a pH of around 9, which makes it alkaline.

The acidity of coffee

Coffee is considered to be moderately acidic due to its pH range of 4.85 to 5.10. Coffee is naturally acidic due to its chlorogenic acid content. This compound gives coffee its characteristic sour taste and is responsible for a large part of its acidity. 

However, it's important to note that not all coffee is created equal when it comes to acidity. Dark roasted coffee tends to have lower acidity levels than lighter roasts, as the roasting process reduces the amount of chlorogenic acid in the beans. Additionally, some coffee blends are specifically marketed as low-acid or acid-neutral, which may be more suitable for individuals with sensitive stomachs.

How does coffee acidity affect your health?

While coffee is acidic, it is not necessarily harmful to health. In fact, coffee has been linked to various health benefits. Studies have suggested that coffee consumption may reduce the risk of several diseases, including type 2 diabetes, liver disease, and some types of cancer. Additionally, coffee contains antioxidants, which can help reduce inflammation and protect against cell damage.

However, for some people, drinking coffee may cause gastrointestinal discomfort, particularly if they have a sensitive stomach or gastroesophageal reflux disease (GERD). In such cases, it may be helpful to reduce coffee intake or switch to a less acidic coffee blend.


Tips for reducing coffee acidity

If you're looking to reduce the acidity of your coffee, there are a few strategies you can try:

  • Choose dark roasts: As mentioned earlier, darker roasts tend to have lower acidity levels than lighter roasts.
  • Use cold-brew methods: Cold-brew coffee has been found to have lower acidity than hot-brewed coffee, as the cold water extraction process reduces the extraction of acids.
  • Add milk: Adding milk to your coffee can help neutralize some of the acidity, making it easier on your stomach.
  • Drink water: Drinking a glass of water before or after your coffee can help dilute the acid in your stomach.


In conclusion, coffee is moderately acidic due to its chlorogenic acid content, with an average pH of around 4.5. While this acidity can have some health benefits, it can also cause digestive issues in some individuals. Choosing darker roasts, trying cold-brew methods, adding milk, and drinking water are all strategies that can help reduce the acidity of your coffee and make it more tolerable for your stomach. As with any dietary change, it's best to consult with a healthcare professional before making significant adjustments to your coffee consumption.
