Demitasse: the cup that holds a traditional shot of espresso is known as a demitasse - the flamboyant word to the small 3 ounce (or smaller) cup. Demitasses can be made of ceramic, stainless-steel, or glass, though porcelain is usually the preferred material. The thicker better, because they must retain heat well for the reason that small 1.5 ounce beverage you craft.

Doser: found on many burr grinders, specially those designed to be utilized with espresso machines. A doser releases a stride of coffee grounds as you pull with a lever which is built into the side in the doser.

Filter Basket: can be a metal, flat bottomed "bowl" shaped insert that matches in the portafilter. The filter basket holds your bed of ground coffee and has numerous skin pores in the bottom allowing the extracted beverage to seep through and pour in a demitasse cup or another receptacle. Most espresso machines include two filter baskets, an individual basket plus a double basket, though some machines feature convertible baskets that enable whether single or double shot of espresso to be manufactured from exactly the same basket.

Frothing Tip: refers back to the perforated tip on a steaming wand. These could have between one and 4 holes, as well as the holes could be either angled sideways or pointing along. They allow the steam through the espresso machine being forced into tiny jets which agitate and heat milk in a great pace and in addition facilitate proper frothing when used to introduce air in the milk.

Portafilter: (often known as a groupo) these devices that holds a filter and finely ground coffee and facilitates quick attachment with an espresso maker.

Shot: another term to spell out a brewed espresso.

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

Tamper: the unit utilized to tamp a bed of loose, finely ground coffee in a portafilter, when preparing for brewing espresso. Most espresso machines include a plastic tamper as a possible accessory, and after market tampers are available.

Let's start using the machine itself. Exactly what it does is force heated water through finely ground, packed (tamped) grounds. There are several varieties of machines around, however. You can find super-automatic machines, semi-automatics, manuals, pod machines and stovetops.
