The liquid contains oils and forms a dark golden brown layer resembling foam along with an espresso shot.

Demitasse: the cup that holds a normal shot of espresso is known as a demitasse - the flowery word for your small 3 ounce (or smaller) cup. Demitasses can be created of ceramic, stainless steel, or glass, though porcelain is truly the preferred material. The thicker the better, since they must retain heat well in this small 1.5 ounce beverage you craft.

Dosage: means the quantity of ground coffee used to develop a shot of espresso. Usually 7 grams per 1.5 ounce single espresso shots.

Doser: entirely on many burr grinders, particularly those made to be used with espresso machines. A doser releases a step of coffee grounds because you pull with a lever that's included in the inside from the doser.

Filter Basket: is a metal, flat bottomed "bowl" shaped insert which fits within a portafilter. The filter basket holds cargo area of ground coffee and has a multitude of tiny holes towards the bottom to allow the extracted beverage to seep through and pour in to a demitasse cup or another receptacle. Most espresso machines include two filter baskets, just one basket as well as a double basket, though some machines feature convertible baskets which allow either a single or double shot of espresso to be produced from the same basket.

Frothing Tip: means the perforated tip on a steaming wand. These may have between one and 4 holes, and the holes might be either angled sideways or pointing all the way down. They allow the steam from your espresso maker to be forced into tiny jets which agitate and also heat milk in a great pace plus facilitate proper frothing when utilized to introduce air in to the milk.

Shot: another term to explain a brewed espresso.

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 requires a more compacting action. Some want a heavy tamping action (using 25 or more pounds of pressure), others want a light tamping action (lower than 15 pounds of pressure exerted).

Tamper: the unit employed to tamp a bed of loose, finely ground coffee inside a portafilter, when preparing for brewing espresso. Most espresso machines include a plastic tamper just as one accessory, after market tampers can be bought.

Let's begin with the machine itself. What it really does is force heated water through finely ground, packed (tamped) grounds. There are various varieties of machines around, however.
