Lungo (Italian for "long") is a coffee beverage made by using an espresso machine to make an Italian-style coffee – short black (single or double dose or shot) with much more water (generally twice as much), resulting in a larger coffee, a lungo. A normal serving of espresso takes from 18 to 30 seconds to pull, and fills 25 to 60 millilitres, while a lungo may take up to a minute to pull, and might fill 130 to 170 millilitres. Extraction time of the dose is determined by the variety of coffee beans (usually a blend of Arabica and Robusta), their grind and the pressure of the machine. The optimum is obtained with 9–12 bars 130–150 ml.{{Citation needed|date=August 2015}} In French it is called café allongé.[1] Related beverages{{Original research|section|date=August 2015}}A caffè lungo should not be mistaken for a caffè americano (an espresso with hot water added to it) or a long black (hot water with a short black added to it, which is the inverse order to an Americano and done to preserve the crema).In the lungo, all the water is brewed, and the lungo is generally shorter than an Americano or a long black. In comparison, the caffè crema is a significantly longer drink, comparable in size to an Americano or long black. (This drink is rare in the English-speaking world.) Like the lungo, it is all brewed water, but is about twice as long as a lungo. FlavourA lungo is less strong, but more bitter, than an espresso, because the additional hot water passing through the ground coffee extracts components that would normally remain undissolved. The more water is passed through the coffee grounds, the more bitter and watery the shot tastes. Conversely, using less water than normal produces a stronger, richer shot known as a ristretto. As the amount of water is increased or decreased relative to a normal shot, the composition of the shot changes due to the fact that the flavour components of coffee dissolve at varying rates. For this reason, a long or short shot will not contain the same ratio of components that a normal shot contains. Therefore, a ristretto is not simply twice as "strong" as a regular shot, nor is a lungo simply half the strength. Moreover, since espresso is brewed under pressure, a lungo does not have the same taste or composition as coffee produced by other methods, even when made with the same ratio of water and ground coffee. BrewingRistretto, normale, and lungo are relative terms without exact measurements.[2] Nevertheless, a rough guide is a brewing ratio of 1:1 for ristretto, 1:2 for normale, and 1:3–1:4 for lungo[3] – a ristretto is thus 30 ml/1 oz (the foamy crema slightly increases this volume), normale is 60 ml/2 oz, and lungo is 90–120 ml/3–4 oz. By contrast, a caffè crema will be approximately 180 ml/6 oz. See also{{portal|Coffee}}
