The rule is: the shorter the brewing time, the more stomach-friendly the coffee. For that reason espresso, despite its intensive and strong taste and appearance, is better digestible than filter coffee. In addition, espresso contains less caffeine than filter coffee.

Espresso is made from mild, low-in-acid coffee beans. They are roasted at high temperatures in a special roasting process and longer than regular coffee Espressobeans (see Coffee roasting grades). The most important acid of the ground coffee, the chlorogenic acid, is thereby eliminated by up to 70 percent. As a consequence the irritants are decomposed and more oils appear.

The brewing process plays also an important role. When brewing filter coffee, the water runs through the coffee powder in the filter for several minutes. This long brewing process gives the filter coffee its typical taste, but it also releases the bitter substances and irritants from the powder. When brewing espresso, in contrast, the water is pressed at very high pressure through the coffee powder. Since the water comes into contact with the ground coffee only for a short time, only few stomach-irritating substances are released. By the way, this is also the reason why espresso contains less caffeine than a cup of filter coffee.
