In the purest sense, espresso coffee is made from 7 grams of finely ground coffee extracted to 1.5 fluid ounces (44 ml) over about 25 seconds.
Espresso is usually topped with a golden creamy color (called the crema).
Each barista and coffee shop have their own particular styles, coffee blends, espresso machines, and even filter basket sizes.

Other popular drinks such as a cappuccino, caffe latte (or latté), caffe mocha (or mochaccino) are based on one or two shots of espresso.
Some countries refer to a shot of espresso as a "short black".
Australia and New Zealand typically serve an additional drink called a flat white - similar to a cappuccino but using only steamed milk and some micro foam rather than fluffy foamed milk on top.
The flat white has now spread to most other countries round the world.
