You need a working semi-automatic espresso machine with an integrated coffee grinder or a separate coffee grinder. The grinder must be able to grind fresh coffee beans, and you must be able to influence the brewing process yourself. Fully automatic coffee machines, capsule and pod machines, machines that only use pre-ground coffee, manual lever machines, and defective equipment are not suitable. For the milk frothing part, a working steam wand is also required. The workshop is intended to help you better use your equipment and is not a repair service.
