[Jason Yan]

A type of strong black coffee made by forcing steam through ground coffee beans.

Espresso = Coffee Squared.
Really strong coffee served in a [teeny tiny] cup, meant to be drank in little sips or in one big gulp like a shot. Is also used to make [Americano] (or a normal coffee) by adding water, or a Cappucino or Latte by adding [hot milk] and froth, or a Mocha by adding chocolate powder, milk and froth.
Most coffee shops put 2 shots of espresso in any coffee, so if you like your coffee strong, ask for an extra shot, if you like it weak, ask for one less.
