Roasting Temperature & Length:

The roasting process has a significant impact on the acidity of coffee. Higher roasting temperatures and longer roasting times tend to decrease acidity. Dark roast coffees, which undergo a longer roasting process, often have lower acidity levels compared to light or medium roast coffees. The prolonged roasting breaks down acids present in the beans, resulting in a smoother and less acidic flavor profile. Conversely, lighter roasts retain more of the original acidity, offering a brighter and tangier taste.

Bean Origin:

The origin of the coffee beans also influences their acidity. Coffees grown in different regions have distinct flavor profiles, including variations in acidity. For example, beans from high-altitude regions like Ethiopia tend to have higher acidity levels compared to beans from lower-altitude regions like Brazil. The soil composition, climate, and altitude of the growing region all play a role in determining the acidity of the beans. Each region’s unique combination of factors contributes to the characteristic acidity found in the coffee beans.

Bean Type:

The type of coffee bean used can contribute to the overall acidity of the coffee. Arabica beans, known for their complex flavors, often have higher acidity levels compared to Robusta beans. Arabica beans contain higher levels of citric acid, which contributes to their bright and acidic flavor profile. Robusta beans, on the other hand, are generally considered to have a lower acidity level, resulting in a stronger and more bitter taste. The inherent characteristics of the beans, including their chemical composition and genetic makeup, influence their acidity and flavor profile.

Brewing Time & Temperature

The brewing time and temperature also affect the acidity of the final cup of coffee. Longer brewing times and higher brewing temperatures generally extract more acids from the coffee grounds, resulting in a more acidic brew. Adjusting the brewing parameters, such as reducing the brewing time or using lower water temperatures, can help reduce the acidity in the coffee. Cold brewing, for example, involves brewing coffee with cold water over an extended period, resulting in a smoother and less acidic cup of coffee.

Variations in acidity


The roasting process has a significant impact on the acidity of coffee. Lighter roasts, such as City or Cinnamon roasts, tend to retain more of the original acidity present in the coffee beans. These roasts often showcase vibrant and tangy flavors, resulting in higher perceived acidity. On the other hand, darker roasts, like French or Italian roasts, undergo more intense roasting, which breaks down and reduces the acidity. The result is a smoother, bolder cup with lower acidity levels. Therefore, if you prefer a less acidic coffee, opting for a darker roast might be the way to go.


The brewing method employed can also influence the acidity of your coffee. Brewing methods that involve longer contact time between water and coffee, such as French press or cold brewing, tend to extract more of the compounds responsible for acidity. As a result, these methods often yield a bolder and more acidic cup of coffee. On the other hand, brewing techniques that utilize shorter contact time, like pour-over or espresso, extract fewer acidic compounds, resulting in a smoother and less acidic coffee. Experimenting with different brewing methods can help you find the perfect balance of acidity that suits your taste preferences.

Ground Size:

Believe it or not, the size of the coffee grounds can impact the acidity of your brew. Finely ground coffee has a larger surface area, allowing for more rapid extraction during brewing. This increased extraction can lead to higher levels of acidity in the resulting cup. Conversely, coarsely ground coffee has a smaller surface area, resulting in a slower extraction process and lower acidity levels. By adjusting the grind size, you can fine-tune the acidity of your coffee to your liking.

Similarly, people with IBS may experience digestive issues, such as bloating and discomfort, when consuming acidic substances like coffee. It’s important to note that the overall effect of coffee on the body’s pH balance is influenced by various factors, including the individual’s diet, lifestyle, and overall health.

Does Coffee Cause Acid Reflux?

Does Coffee Cause Acid Reflux? Caffeine, a key component of coffee, is known to have effects on the gastrointestinal system that can potentially trigger heartburn and exacerbate acid reflux symptoms. When consumed, caffeine relaxes the esophageal sphincter, a muscle that acts as a barrier between the stomach and the esophagus. This relaxation can allow stomach acid and food to flow back up into the esophagus, leading to the uncomfortable symptoms of acid reflux. 

Additionally, caffeine can stimulate the production of stomach acid, further contributing to the likelihood of acid reflux episodes. Therefore, it is plausible to suggest that coffee consumption, particularly due to its caffeine content, may cause or worsen acid reflux symptoms.

Is Decaf Coffee Acidic? 

Is Decaf Coffee Acidic? While decaffeinated coffee might be mildly less acidic on a pH scale than caffeinated coffee—and this will vary based on not only the coffee bean’s variety but also the decaffeination process it undergoes—it is not significantly less acidic, perhaps the difference between a 4.7 and a 5 on the pH scale. The acidity of coffee is mainly influenced by compounds such as chlorogenic acid, quinic acid, and citric acid, which are present in both regular and decaf coffee. 

However, the exact acidity level of decaf coffee can differ depending on the specific beans used and the decaffeination method employed during processing. It’s worth noting that individual sensitivity to acidity may vary, and some people with acid reflux or sensitive stomachs might find decaf coffee to be a more tolerable alternative to regular coffee.
