With Espresso Italiano from Caffe Sempione in Valais. Always with the strongest setting, of course.

Maestro Lorenzo Classic (Coop) with grinder setting Fine (this is the control above the brewing unit when you remove the cover on the right-hand side). Then set the bean setting to two beans. Generally, I can only recommend using the finest grinder setting, so the coffee has more flavour and is less acidic.

Espresso Marimba from Coop (organic). Setting: medium amount of coffee (display of two beans) Adjustment via amount of water.
