A cafe latte is prepared using 1 part espresso and 2 parts steamed milk. It’s usually served as a 6-8 ounce drink. A wet cappuccino is similar but is usually served as a smaller 5-6 ounce drink with slightly more foam. It’s also worth noting that many cafes now serve a modified version of the traditional latte that uses a higher ratio of milk - often 1:7 or greater.
