Here are the typical coffee drinks you will find in Italy:
caffè (espresso): a small cup of very strong coffee, i.e., the typical espresso (20 to 25ml)
caffè doppio: 2 espresso served in one cup
caffè ristretto: an even more condensed version of an espresso (less than 20 ml)
caffè macchiato (or un macchiato): an espresso with a drop of milk. You can order either a macchiato caldo (drop of steamed milk), a macchiato freddo (drop of cold milk) or a macchiato con schiuma di latte (with froth milk).
caffè Americano: weaker than espresso and served in a large cup or a glass, but still stronger than American-style coffee. It consists of an espresso to which hot water has been added after the brewing process (about 80ml). It is different from a caffé lungo (see below).
caffè lungo: where more water (about double) is let through the ground coffee, yielding a weaker taste (about 40ml).
