- The Espresso drinkers (ET)
- The cappuccino drinkers (CT)
Coffee preparation for the CT requires 2 -Kreismaschine - 2 brewing systems, one for the water, the other for steam dispensing. For the espresso preparation of ET it takes only 1 circle.
I think one of the important most component is a PID (Electronic Temperature Control).
As "Faema 61 brewing groups" without PID like overheat and coffee tastes known to be very different at different temperatures, is a PID advantageous. Some Faema machines offer this. So the temperature to +/- 1 level can be regulated.
A Faema machine without PID always needs previously an empty reference (Flushing), to cool!
Now we have touched on a major issue
At full purse can be carried out more precisely. There are also systems like that of
La Marzocco (GS 3) or Dalla Corte (mini), which does not concern the water through a heat exchanger. In such systems are usual tolerances of only 0.2 degrees.
(What is the tolerance of the partner is, in terms of such a purchase is not subject of this chapter.)
