I grind espresso beans instead of coffee beans (powder fineness like instant coffee) and then the broth powder as normal coffee. The reason: Espresso contains caffeine, but the stomach than coffee. Espresso beans are harder than coffee beans, so I was skeptical at first, but it worked well and I'm very happy with the grinding result. Who more than 2-3 servings wants to make powder, which should allow for some time, because you have the unit in between let rest a few minutes, so as not to overheat. Before first use of the device should read the description well.
