Panel (control panel): the area where the user controls most or all of the functions of the Italian coffee maker. There are usually power switches, cooking control switches and steam controllers. In some models there will also be a hot water discharge controller. They come in different forms: some control panels use rocket-style switches and control handles; some use key switches; and others use pressure-sensitive switches.

Crema

Enhancer (Coffee Oil Enhancer): is a device or design used to easily produce "coffee oil" when brewing espresso (unproven). See pressurized handle or pressurized filter. Coffee oil enhancers do not produce coffee oil as traditional brewing methods do, and often lead to poor taste.

Crema (Coffee Fat): for models that do not use coffee oil enhancers, this is an indication of the quality of espresso brewing, which is produced when air and carbon dioxide in the liquid are released under high pressure. There is also emulsified oil in the liquid, and a deep golden brown surface layer formed by foam accumulation on the surface of espresso.

Cup

Tray (cup holder): it is part of the Italian coffee machine, and when you start making coffee, you can put the coffee cup on it. The cup holder is on top of the drip tray (or part of the drip tray).

Cup Warmer (cup warmer): the part of an Italian coffee machine that heats a coffee cup. It is usually located on the top of the coffee machine, above the boiler (the boiler is inside the machine). Not all Italian coffee machines have cup warmers. Some models use active cup warmers (including Solis SL-90). The cup warmer is very useful, without it, just 1.5 ounces of coffee poured into a cold cup will quickly lose calories.
