Cappuccino is an Italian coffee-base drink prepared with espresso, hot milk, and milk foam. A cappuccino differs from a caffé latte in that it is prepared with much less steamed or textured milk than the caffé latte with the total of espresso and milk/foam making up between approximately 150 ml and 180 ml (5 and 6 ounces). A cappuccino is traditionally served in a porcelain cup, which has far better heat retention characteristics than glass or paper. The foam on top of the cappuccino acts as an insulator and helps retain the heat of the liquid, allowing it to stay hotter longer.
