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.
Louise is such a wimp, she drinks grande latte's with only one shot of espresso. It's hardly worth it!
Espresso is served in shots of around 1.5 ounces, and is frequently added to steamed milk to make various coffee beverages.
Often mistakenly called "expresso".
