Espresso From Wikipedia, the free encyclopedia
Jump to: navigation , search
This article is about the coffee preparation method and the resulting beverage. For other uses, see Espresso (disambiguation) .
Espresso brewing, with a dark reddish-brown
foam , called
crema or
schiuma .
Caffe espresso , or just espresso is a concentrated coffee beverage brewed by forcing hot water under pressure through finely ground coffee.
Compared to other coffee brewing methods, espresso often has a thicker consistency, a higher concentration of dissolved solids, and crema ( foam ) . As a result of the pressurized brewing process, all of the flavours and chemicals in a typical cup of coffee are very concentrated. For this reason, espresso is the base for other drinks, such as lattes , cappuccino , macchiato , mocha!s , and americanos .
The first espresso machines were introduced at the beginning of the 20th Century, with the first patent being filed by Luigi Bezzera of Milan , Italy , in 1901. Up until the mid-1940s, when the piston lever espresso machine was introduced, it was produced solely with steam pressure.
While espresso has more caffeine per unit volume than most beverages, compared on the basis of usual serving sizes , a 30 mL (1 fluid ounce) shot of espresso has about half the caffeine of a standard 180 mL (6 fluid ounce) cup of drip brewed coffee, which varies from 80 to 130 mg, [ 1 ] and hence a 60 mL (2 oz) double shot of espresso has about the same caffeine as a 180 ml (6 oz) cup of drip brewed coffee. In coffee brewing terms, espresso and brewed coffee should have the same extraction (about 20% of the coffee grounds are extracted into the coffee liquid), but espresso has a higher brew strength (concentration, in terms of dissolved coffee solids per unit volume), due to having less water.
[edit ] Brewing process A modern espresso machine.
A manual espresso machine
Preparation of espresso requires an espresso machine . The act of producing a shot of espresso is often termed "pulling" a shot, originating from lever espresso machines which require pulling down a handle attached to a spring-loaded piston, forcing hot water through the coffee at high pressure. Today, however, it is more common for the pressure to be generated by steam or a pump.
This process produces an almost syrupy beverage by extracting and emulsifying the oils in the ground coffee.
[edit ] Espresso roast Espresso is not a specific bean or roast level ; it is a method of making coffee. Any bean or roasting level can be used to produce authentic espresso. A darker or lighter roast will translate into a bitter or acid flavor respectively. Mixtures where there are several roast levels are common.
In Italy roast levels can vary quite a bit. In Southern Italy, a darker roast is often preferred, but the farther north one goes in the country, the trend moves towards lighter roasts. [ 2 ]
[edit ] Baristas Main article: Barista
An expert operator of an espresso machine is a barista , the Italian word for a bartender .
[edit ] Popularity Espresso is the main type of coffee in many parts of the world, though this is a recent phenomenon.
With the rise of various coffee chains in the 1990s, espresso-based drinks rose in popularity in the United States, with the city of Seattle viewed as one of the origins of modern interest. In addition to the Italian style of coffee, coffee chains typically offer many variations by adding syrups, whipped cream, flavour extracts, soy milk, and various spices to their drinks.
Espresso has become increasingly popular in recent years, in regions where coffee has traditionally been prepared in other ways. In Northern Europe , specialty coffee chains have emerged, selling various sorts of espresso from street corners and high streets .
Home espresso machines have increased in popularity with the general rise of interest in espresso. Today, a wide range of home espresso equipment can be found in kitchen and appliance stores, online vendors, and department stores.
[edit ] History The popularity of espresso developed in various ways; a detailed discussion of the spread of espresso is given in ( Morris 2007 ), which is a source of various statements below.
In Italy, the rise of espresso consumption was associated with urbanization, espresso bars providing a place for socialization. Further, coffee prices were controlled by local authorities, provided that the coffee was consumed standing up, encouraging the "stand at a bar" culture.
In the Anglosphere, espresso became popular particularly in the form of cappuccino, due to the tradition of drinking coffee with milk and the exotic appeal of the foam; in the United States this was more often in the form of lattes , particularly with flavored syrups added. The latte is claimed to have been invented in the 1950s by Italian American Lino Meiorin of Caffe Mediterraneum in Berkeley, California , as a long cappuccino, and was then popularized in Seattle, [ 3 ] and then nationally and internationally by Seattle-based Starbucks in the late 1980s and 1990s.
In the United Kingdom, espresso grew in popularity among youth in the 1950s, who felt more welcome in the coffee shops than in public houses (pubs).
In Australia, espresso consumption grew in popularity due to the ban on serving alcohol after 6 pm.
Espresso was initially popular particularly within the Italian diaspora, growing in popularity with tourism to Italy exposing others to espresso, as developed by Eiscafes established by Italians in Germany.
Initially expatriate Italian espresso bars were downmarket venues, serving the working class Italian diaspora ? and thus providing appeal to the alternative subculture / counterculture; this can still be seen in the United States in Italian American neighborhood such as Boston's North End, New York's Little Italy, and San Francisco's North Beach. As specialty coffee developed in the 1980s (following earlier developments in the 1970s and even 1960s), an indigenous artisanal coffee culture developed, with espresso instead positioned as an upmarket drink.
Today coffee culture commentators distinguish large chain, midmarket coffee as "Second Wave Coffee", and upmarket, artisanal coffee as Third Wave Coffee .
In Northern Europe (particularly Scandinavia) and to a greater extent in most of Central Europe , espresso is associated with European identity, as in New Europe . By contrast, in Hungary, espresso is associated with pre-Communist cafe culture.
In the Middle East Espresso is quite popular and becoming more widely available with the openings of Western coffee shop chains. However, the most common type of coffee remains Turkish coffee which is also served short like espresso. Turkish coffee is almost the same measure of ground coffee as an espresso added to water and brought to a boil. It is quite common that ground Cardamom is added to the blend of coffee for added flavor.
Currently in Britain espresso is uniformly popular across all pre-retirement age groups, but is unevenly popular across class lines, being primarily associated with educated professionals.
[ edit ] Cafe vs. home A distinctive feature of espresso as opposed to other coffee is espresso's association with cafes, due both to the equipment and skill required, and thus espresso has been primarily a social experience.
Initially espresso machines were not available for home use, domestic machines only developing in the 1970s, and remaining expensive, bulky, and requiring skill to operate. In recent years the development of easy-to-use home espresso makers based on coffee pods has increased the quantity of espresso consumed at home, though top-quality espresso continues to require expensive equipment and skill, and remains primarily associated with cafes or the enthusiast community.
In recent years true espresso brewing has become possible virtually anywhere with small handheld machines.
[ edit ] Etymology and usage of the term
The origin of the term "espresso" is the subject of considerable debate. [ citation needed ] Although some Anglo-American dictionaries simply refer to "pressed-out", [ 4 ] "espresso," much like the English word "express," also conveys the sense of "just for you" and "quickly," both of which can be related to the method of espresso preparation.
The words express , expres and espresso each have several meanings in English, French and Italian. The first meaning is to do with the idea of 'expressing' or squeezing the flavour from the coffee using the pressure of the steam. The second meaning is to do with speed, as in a train. Finally there is the notion of doing something 'expressly' for a person... The first Bezzera and Pavoni espresso machines in 1906 took forty-five seconds to make a cup of coffee, one at a time, expressly for you. (Bersten (cited below) p. 99) -
Many Latin based countries, such as France, Spain, and Portugal, use the expresso form. [ citation needed ] In the United States and Canada, both espresso and expresso are used. [ 5 ] Italy uses the term espresso , substituting most x letters in Latin root words with s ; x is not considered part of the standard Italian alphabet. Italian people commonly refer to it simply as "caffe" ( coffee ), espresso being the ordinary coffee to order.
In Slovakia and the Czech republic, espresso is commonly referred to as "presso" and is served with liquid creamer on the side by default. [ citation needed ] This is referred to as "presso with milk" ( presso s mliekom (Slovak) ).
Modern espresso, using hot water under pressure, as pioneered by Gaggia in the 1940s, was originally called " crema caffe ", in English "cream coffee", as can be seen on old Gaggia machines, due to the crema. [ 6 ] This term is no longer used, though "crema caffe" and variants ("caffe crema", "cafe crema") find occasional use in branding.
[edit ] Shot variables See also: Doppio , Ristretto , and Lungo
The main variables in a shot of espresso are the size and length . [ 7 ] [ 8 ] Terminology is standardized, but precise sizes and proportions vary substantially.
Cafes generally have a standardized shot (size and length), such as "triple ristretto", [ 8 ] only varying the number of shots in espresso-based drinks such as lattes, but not changing the extraction ? changing between a double and a triple require changing the filter basket size, while changing between ristretto, normale, and lungo require changing the grind, and cannot easily be accommodated in a busy cafe, as fine tweaking of the grind is a central aspect to consistent quality espresso-making, which is disrupted by major changes such as ristretto to lungo.
[ edit ] Size The size can be a single, double, or triple, which correspond roughly to a 1, 2, and 3 fluid ounce (approximately 30, 60 or 90ml) standard ("normale") shot, and use a proportional amount of ground coffee, roughly 7?8, 14?16, and 21?24 grams; correspondingly sized filter baskets are used. The Italian term doppio is often used for a double, with solo and triplo being more rarely used for singles and triples. The single shot is the traditional shot size, being the maximum that could easily be pulled on a lever machine, while the double is the standard shot today.
Single baskets are sharply tapered or stepped down in diameter to provide comparable depth to the double baskets and, therefore, comparable resistance to water pressure. Most double baskets are gently tapered (the "Faema model"), while others, such as the La Marzocco, have straight sides. Triple baskets are normally straight-sided.
Portafilters will often come with two spouts, usually closely-spaced, and a double-size basket ? each spout can optionally dispense into a separate cup, yielding two solo-size (but doppio-brewed) shots, or into a single cup (hence why they are closely spaced). True solo shots are rare, with a single shot in a cafe generally being half of a doppio shot.
In espresso-based drinks, particularly larger milk-based drinks, a drink with three or four shots of espresso will be called a "triple" or "quad", respectively, but this does not mean that the shots themselves are triple or quadruple shots. Rather, generally double shots will be used, with 1½ shots used in a triple (split via the two spouts), and 2 shots used in a quad.
[ edit ] Length The length of the shot can be ristretto ("restricted"), normale/standard ("normal"), or lungo ("long"): these correspond to a smaller or larger drink with the same amount of ground coffee and same level of extraction. Proportions vary, and the volume (and low density) of crema make volume-based comparisons difficult (precise measurement uses the mass of the drink), but proportions of 1:1, 1:2, and 1:3?4 are common for ristretto, normale, and lungo, corresponding to 1 oz, 2 oz, and 3?4 oz (30 ml, 60 ml, 90?120 ml) for a double shot. "Ristretto" is the most commonly used of these terms, and double or triple ristrettos are particularly associated with artisanal espresso.
Ristretto, normale, and lungo are not simply the same shot, stopped at different times ? this will result in an underextracted shot (if run too short a time) or an overextracted shot (if run too long a time). Rather, the grind is adjusted (finer for ristretto, coarser for lungo) so that the target volume is achieved by the time extraction finishes.
A significantly longer shot, rare in the Anglosphere , is the caffe crema , which is longer than a lungo, ranging in size from 4?8 oz (120?240 ml), and brewed in the same way, with a coarser grind.
Espresso can also be lengthened by dilution with hot water, as in the Americano or long black .
The method of adding hot water produces a milder version of original flavor, while passing more water through the load of ground coffee will add other flavors to the espresso, which might be unpleasant for some people.
[ edit ] Espresso-based drinks In addition to being served alone, espresso is frequently blended, notably with milk (either steamed (without significant foam), wet foamed (" microfoam "), or dry foamed) and with hot water. Notable milk-based espresso drinks, in order of size, include: macchiato , cappuccino , flat white , and latte , while espresso and water drinks especially include the Americano and long black . Others include the red eye and latte macchiato . The cortado , piccolo, and galao are made primarily with steamed milk with little or no foam.
In order of size, these may be organized as follows:
Traditional Macchiato: 35?40 ml, 1 shot (30 ml) with a small amount of milk (mostly steamed, with slight foam so there is a visible mark) Modern Macchiato: 60 ml or 120 ml, 1 or 2 shots (30 or 60 ml), with 1:1 milk Cortado: 60 ml, 1 shot with 1:1 milk, little foam Piccolo: 90 ml, 1 shot (30 ml) with 1:2 milk, little foam Galao: 120 ml, 1 shot with 1:3 milk, little foam Flat white: 150 ml, 1 or 2 shots (30 or 60 ml), with 1:4 or 2:3 milk Cappuccino: 150?180 ml, 1 or 2 shots (30 or 60 ml), traditionally with significant dry foam, today often found with wet foam Latte: 240?600 ml, 2+ shots (60 ml), with 1:3?1:9 milk Some common combinations may be organized graphically as follows:
mixed with frothed milk hot water espresso is on top latte macchiato long black bottom caffe latte caffe americano
Methods of preparation differ between drinks and between baristas. For macchiatos, cappuccino, flat white, and smaller lattes and Americanos, the espresso is brewed into the cup, then the milk or water is poured in. For larger drinks, where a tall glass will not fit under the brew head, the espresso is brewed into a small cup, then poured into the larger cup; for this purpose a shot glass or specialized espresso brew pitcher may be used. This "pouring into an existing glass" is a defining characteristic of the latte macchiato and classic renditions of the red eye. Alternatively, a glass with existing water may have espresso brewed into it ? to preserve the crema ? in the long black. Brewing onto milk is not generally done.

"long"): More water (about 1.5x volume) is let through the ground coffee, yielding a weaker taste (40 mL). Also known as an allonge in French. Caffe Macchiato (It. "stained"): A small amount of milk or, sometimes, its foam is spooned onto the espresso. In Italy it further differentiates between caffe macchiato caldo (warm) and caffe macchiato freddo (cold), depending on the temperature of the milk being added; the cold version is gaining in popularity as some people are not able to stand the rather hot temperature of caffe macchiato caldo and therefore have to wait one or two minutes before being able to consume this version of the drink. The caffe macchiato is to be differentiated from the latte macchiato (described above). In France, known as a "Noisette". Cafe Marocchino : Created in Turin , normally served in a small glass, this is a shot of espresso, a sprinkling of cocoa, frothed whole milk (about two table spoons to bring to the brim of the glass), then a further sprinkling of cocoa on top Marron :(Brown) Etymology from Venezuela.
