A long black is a style of coffee commonly found in Australia and New Zealand. It is similar to an Americano, but with a stronger aroma and taste.
A long black is made by pouring a double-shot of espresso or ristretto over hot water. Typically about 100 - 120 milliliters of water is used (3.5 - 4 ounces) 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.
Espresso is a big part of this menu. Try the long black ($3 to $3.50), a double shot of espresso over hot water, comparable to an Americano.
