Espresso Machine: Keypad
With a semi-automatic
espresso machine, the keypad can be used to push a
predefined amount of water through the coffee pellet.
The keypad is easy and useful, but is not the best way to
determine shot size. It is essential to watch the shot
brew and stop the flow of water before the crema turns pale
in color. This pale color crema deteriorates the crema
already present in the cup and ruins the delicate flavor.
Typically, there is a on/off switch next to the keypad which should
be used instead of the keypad. Typical shots are 1-1.5
ounces, not the 2 ounces that you are normally served.
