Most espresso machines include two filter baskets, just one basket as well as a double basket, though some machines feature convertible baskets which allow sometimes a single or double shot of espresso being created from the identical basket.

Frothing Tip: means perforated tip on the steaming wand. These may have between one and four holes, along with the holes might be either angled sideways or pointing along. They allow the steam from the espresso machine to be forced into tiny jets which agitate and heat milk at a great pace plus facilitate proper frothing when employed to introduce air in to the milk.

Tamp: (also tamping) the action of pressing and compacting a bed of loose, finely ground coffee, in planning for brewing espresso. Different machines require different tamping methods. Steam powered espresso uses a leveling tamp, where piston lever, spring lever, and pump espresso uses a more compacting action. Some prefer a heavy tamping action (using 25 or higher pounds of pressure), others desire a light tamping action (lower than 15 pounds of pressure exerted).

Tamper: these devices accustomed to tamp a bed of loose, finely ground coffee in the portafilter, in preparation for brewing espresso.
