The coffee beans, the grind size, the amount of ground coffee, the pressure at which
the coffee powder was tamped into the filter insert as well as the extraction time
are crucial factors for a perfect espresso. Furthermore, they determine whether it is
stronger or less strong and which kind of crema develops. You can experiment with
these factors to create the espresso that perfectly suits your taste.
If you choose a finer grind size, you have to fill a larger amount of coffee into the
filter insert. However, you have to tamp the coffee less firmly. Otherwise, the water
will not be able to flow through the ground coffee even when the pressure is high.

If you select a larger grind size, you should fill a smaller amount of coffee into the
filter insert. If you do that, you have to tamp the coffee more firmly. Otherwise, the
water runs through the ground coffee too quickly.
The ground coffee always has to be tamped.
Always store the coffee beans in an airtight, closed container, protected from mois-
ture and in cool surroundings. A vacuum pack would be perfectly suited. Buy coffee
beans in small packaging units to reduce storage time and do not keep more than
a weeks' worth of beans.
