Caffè macchiato

Caffè macchiato , sometimes called espresso macchiato and often shortened to just macchiato in English, is an espresso coffee drink with a small amount of milk, usually foamed. In Italian, macchiato means 'stained' or 'spotted', so the literal translation of caffè macchiato is 'stained coffee' or 'marked coffee'. The origin of the name macchiato stems from baristas needing to show the serving waiters the difference between an espresso and an espresso with a tiny bit of milk in it; the latter was "marked". The idea is reflected in the Portuguese name for the drink: café pingado, meaning 'coffee with a drop'.
