Long black

A long black is a style of coffee commonly found in Australia and New Zealand, made by pouring a single shot of espresso into hot water. It is similar to an americano, in which hot water is poured into one shot of espresso. Typically about 100–120 milliliters (3.5–4 ounces) of water is used but the measurement is considered to be flexible to individual taste. The smaller volume of water compared to an Americano is responsible for its stronger taste. Both retain the crema when brewed properly, though in the long black the crema will be more pronounced.
