Espresso machines

The stovetop espresso makers do not require any electricity to operate, making them very popular amongst tourists or hikers.
The machine has 3 chambers, with water in the bottom one and coffee landing into the top one after brewing.
They produce a dark coffee but usually lack the pressure to create a foam.

The Original "MOKA" stovetop espresso maker

The steam powered espresso maker can be compared to the stovetop models in the way they work and what coffee they brew.
However, they are alot bigger in size and are not that popular because of that.
Identical to the stovetop models, they usually don't produce enough pressure to create a foam.

A steam espresso maker

This model is the root of all espresso machines. The device was invented in 1938 in Italy by Achille Gaggia.
A piston driven machine is still an excellent way of making an espresso. Coffee brewed by this type comes with a nice foam. Operating one of these however is not an easy task and requires some muscles in the arms.
The model is usually only used as decoration or mild use, and coffeehouses will usually stick to another model.

A manual lever piston-driven espresso machine

Pump-driven espresso makers are exactly like piston-driven models. The only difference is the pressure comes form a automatic pump.
This is the most popular model, both for home use and commercial use.
Different models either have a water reservoir or are directly connected to the plumbing of the establishment.
