Coffee from Sumatra is one of the least acidic ones – usually it's earthy and has more body than and mouthfeel compared to African or Central American coffees.
Dark roast coffee has been found to suppress stomach acid secretion, while a more medium roast coffee accelerates it.
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…
Longer roasting times and higher heat create more quinic acid that upsets the digestive tract. Opt for Arabica coffee. Arabica beans have less acid than Robusta beans, so choose a blend with 100% high-quality Arabica. Look for coffee roasted in smaller batches.
Make sure to obtain 100% arabica coffee. These beans are lower in acidity than the Robusta type. Look for beans cultivated at lower altitudes as well. Sumatra, Brazil, and numerous Central American countries all produce low-acid coffees.
To reduce the acidity levels in coffee, choose dark roast beans over light roast, drink cold brew instead of hot, increase brew time, go for a finer grind, and brew coffee at a lower temperature. All of these methods will help neutralize the acid levels in Coffee for a fantastic experience.
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.
Light roasts have a light brown, tan, color and lack of oil on the roasted beans. They have the highest acidity and are the brightest of the three roast levels.
Medium roast coffee is a brown color and rarely has an oily surface. These coffees have a medium acidity and body, as well as a rounded flavor profile. Roasting to this level also preserves many of the unique flavors of the coffee's origin, but it also begins to reach into the deep caramel sweetness of a longer roast.
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).
Try cold brewing.
Cold brewing extracts less acid and bitter compounds from the beans, which can make coffee easier to tolerate. Cold brewing doesn't mean you must drink your coffee cold. You can reheat cold-brewed coffee in a small pot or microwave.

Their report, presented here at the 239th National Meeting of the American Chemical Society, included the counter-intuitive finding that espresso, French roast, and other dark-roasted coffee may be easier on the tummy because these roasts contain a substance that tells the stomach to reduce production of acid.

In order to decrease the acidity of these secretions, it is best to minimize the amount of caffeine in your diet," Zigler says. Caffeine may also relax the lower esophageal sphincter, triggering acid reflux or making it worse.
Choose A Darker Roast Coffee
While darker roasted coffees have the same PH and acid levels as lighter roast the process of roasting a coffee longer and dark releases a chemical which has been shown to inhibit the stomach acid production.
