Preliminary results suggest that stomach acid surges for a longer time when subjects drink light-roast coffee compared to dark-roast.
Dark Roasts - a study published in 2010 found that dark roast coffee is easier on the stomach than light roasts because it produces an ingredient that prevents hydrochloric acid from building up in the stomach. Cold Brew - brewing coffee using the cold brew method has been shown to increase the pH level of coffee.
Dark roast coffees tend to be less acidic because they contain fewer compounds that cause stomach cells to produce acid.

One study found that dark-roasted coffees are easier on the stomach than light or mild roasts because they contain a particular ingredient that keeps your stomach from producing too much acid.
Consider a Darker Roast
A 2014 study showed that a dark roast coffee contained a balance of chemicals that produced less stomach acids than a medium roast. The dark roast had higher amounts of a chemical compound called NMP. It also had lower amounts of two other compounds known as C5HTs and chlorogenic acids (CGAs).
So, for a sensitive stomach, cold brew is your best option - you get all the caffeine with less of the acidity. They've proven to be up to 70% less acidic than hot brewed coffee made from the same beans… yes please!
The researchers found that the lighter the roast, the higher the chlorogenic acid content—and the better the coffee extract protects human cells against cell damage. Other research has found that antioxidant activity reaches a maximum level with light roasts.
SAN FRANCISCO — Roasting coffee beans doesn't just impart bold, rich flavor. It also creates a compound that helps dial down production of stomach acid, according to research presented on March 21 at the spring meeting of the American Chemical Society.

Light roast, medium roast, and dark roast coffee beans will have varying levels of acidity, dark roast having the lowest acid coffee, and light roast the highest acid level. In addition, it will also change the entire flavor profile of the coffee beans and your cup of coffee.
The acid in coffee can irritate your digestive tract. Choose coffee substitutes like green tea or low-acid coffee brands like Golden Ratio to give your stomach a break and an anti-inflammatory effect. Brands that are low-acid are also a gentler approach to that morning cup.
Then, if you notice an improvement, either continue to abstain from coffee or gradually reintroduce it to determine how much your body can tolerate, he suggests. Decaf or light-roast coffee may be beneficial for IBS sufferers.
Out of the three roasts—light, medium, and dark—the award for lowest acidity goes to dark roast coffee. This roast has fewer compounds that cause stomach cells to produce acid.
Overall, lighter roasts generally have less caffeine and more antioxidants than darker roasts. The type of bean can affect the caffeine content, but both Arabica and Robusta beans can give you the full health benefits of coffee.
Published in the Journal of Medicinal Food, the study reveals that light roasts offer more antioxidants than their dark roast counterparts.
Light roasts tend to have more delicate yet complex flavor profiles than dark roasts. Dark roasts tend to have deep but simple flavors due to some of the initial flavors of the beans being lost or changed during the roasting process. Dark roast is sometimes described as tasting more bitter than light roast.
This happens for two major reasons: First, coffee, as well as other caffeinated beverages, can affect the stomach strongly because they contain caffeine. Caffeine has been shown to cause frequent contractions in the digestive tract. It can also increase stomach acidity by triggering the production of more gastric acid.
Brewing coffee with cold water extracts fewer stomach-irritating chemicals and compounds, including the many different acids that occur naturally in coffee beans. All this means that your cup of hot coffee can have extra acid that may be irritating your stomach.
For instance, decaffeinated coffee may be a better option for those with IBS since it contains significantly less caffeine. Furthermore, some types of coffee, such as cold brew, are generally less acidic and may be better tolerated by some individuals.
Cut down on caffeine
But caffeine can cause dehydration, which makes your digestive system sluggish and can lead to blockages. So sorry, coffee fans, but when it comes to reducing bloating, the less caffeine the better.
Hydrate! Substituting a glass of water for that next cup of coffee can make a world of difference. Countering the slight diuretic effects of coffee with a glass of water can slow down or even stop the bloat.
