Does Coffee Give You Gas?

This may surprise you, but coffee can indeed cause gas. When you drink it on an empty stomach, and it reduces the hydrochloric acid, your stomach may have trouble breaking down protein. All that undigested protein starts eating all the gut bacteria that produce hydrogen sulfide. The result is, well, a gassy stomach.

Why does coffee make me so gassy?

The caffeine in coffee increases the level of acid in the intestines. This can stimulate your digestive tract, potentially leading to abdominal bloating and gas, according to the University of Michigan Health System. Even if you are drinking decaffeinated coffee, some caffeine is still present.

How do you prevent gas from coffee?

Cold brewing coffee in cold water (instead of hot water like normal) reduces the acid levels of the final drink as much as 66%. Once you've brewed the concentrate, you can still cut it with hot water to enjoy a hot mug like normal.
