The name espresso is Italian in origin. It was initially coined around 1900 and, loosely translated, means coffee brewed expressly (just) in your case. Today, you will often realize that people incorrectly pronounce or spell it "expresso."

So, what makes a true espresso?

It isn't really the bean. It isn't the blend. It isn't really the roast. It's not that it must be manufactured by a particular kind of machine.

The reality is, you can use any type of bean, blend and roast, it just depends on your own tastes.

Why is espresso may be the way the coffee is prepared. Espresso coffee is really a small (1 or 2 oz.) shot of pressure-brewed coffee, using about 1 Tablespoon of finely ground coffee. Brewing takes about 25 to Thirty seconds when done efficiently, it will include a layer of rich, dark golden cream, called crema on the surface. This crema is but one indicator of a quality espresso. Creating a great espresso is really an art form and a science.

The important thing Words of Espresso

As with any other field, espresso possesses its own little language that you need to know. Here is a small listing of keywords that you'll often hear when reading about anything espresso.

BAR: Pressure rating used on most pump driven espresso machines. 9 BAR, the normal accepted pressure for brewing espresso is 8.8 atmospheres of pressure or 130 pounds per square in .. Nearly every consumer espresso maker can perform producing this pressure consistently.

Burr Grinder: is the recommended form of grinder for proper espresso making. A burr grinder features two disks, one stationary, one rotating, which slice away portions of an espresso bean into very fine particles.

Crema: is among the sure signs and symptoms of an adequately brewed shot of espresso (in non crema-enhancing machines) and is produced by the dispersion of gases - air and co2 - in liquid with a high pressure. The liquid contains oils and forms a dark golden brown layer resembling foam along with an espresso shot.

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

Dosage: means level of ground coffee employed to produce a shot of espresso. Usually 7 grams per 1.5 ounce single espresso shots.

Doser: seen on many burr grinders, especially those designed to be used with espresso machines. A doser releases a measure of coffee grounds while you pull with a lever that is included in along side it of the doser.

Filter Basket: is really a metal, flat bottomed "bowl" shaped insert that fits within a portafilter. The filter basket holds your bed of ground coffee and possesses many skin pores at the base to allow the extracted beverage to seep through and pour right into a demitasse cup or any other 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 being manufactured from the identical basket.

Frothing Tip: refers back to the perforated tip over a steaming wand. These could have between one and 4 holes, along with the holes can be either angled aside or pointing straight down. They let the steam in the espresso machine being forced into tiny jets which agitate and also heat milk at the great pace and also facilitate proper frothing when used to introduce air into the milk.

Portafilter: (often known as a groupo) these devices that holds a filter and finely ground coffee and facilitates quick attachment to a espresso maker. Portafilters usually have a handle for quick handling, and spouts underneath to allow for your espresso to pour into cups. On better espresso machines, they're manufactured from copper or brass, and are coated with chrome. The handles are often wood, bakelite, or plastic. On more affordable machines they may be aluminum, steel, or any other metals and plastics.

Pull: an expression employed to describe brewing a trial of espresso. Comes from the experience employed to prepare espresso inside the 1950s, 1960s, and beyond - pulling on the lever to cock a spring within a piston group with an espresso machine. Also Espresso Pull, Pull an attempt.

Steam Wand: is often a visible, external pipe available on most espresso machines which is used to froth and steam milk, to offer domestic hot water (on some machines), and heat espresso cups. Some also employ the steam wand to heat water. It is controlled with a steam knob that opens and closes the steam valve inside the machine.

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 readiness for brewing espresso. Different machines require different tamping methods. Steam powered espresso takes a leveling tamp, where piston lever, spring lever, and pump espresso uses a more compacting action. Some want a heavy tamping action (using 25 or maybe more pounds of pressure), others should you prefer a light tamping action (less than 15 pounds of pressure exerted).

Tamper: the unit accustomed to tamp a bed of loose, finely ground coffee within a portafilter, in planning for brewing espresso. Most espresso machines incorporate a plastic tamper as an accessory, and after market tampers can be purchased. These are measured in millimeter sizes, corresponding using the filter basket internal diameter of one's espresso maker. Most commercial, prosumer, and end consumer espresso machines work with a 58mm tamper; other common sizes are 49mm, 53mm, and 57mm.

Thermoblock: in most espresso machines, the heating system is formed much like a car radiator, a number of heated metal coils or channels which water must move across and grow progressively hotter because it reaches the boiler.

The Espresso Machine

Let's move on using the machine itself. What it does is force heated water through finely ground, packed (tamped) grounds. There are several forms of machines around, however. There are super-automatic machines, semi-automatics, manuals, pod machines and stovetops.
