An espresso cup is a small, thick-walled cup made of porcelain, earthenware or glass that is specially designed for making espresso. The thick walls provide better insulation so that the coffee stays hot and can be enjoyed at the optimum temperature. Espresso cups are often pre-heated to ensure the correct serving temperature of the drink.
Usually, an espresso cup has a capacity of 60 to 80 ml, which is perfect for a single espresso serving of about 40 ml. However, espresso is sometimes drunk as a double espresso, which is about 80 ml. Depending on the size of the cup, a double espresso can either be served to the brim in a traditional espresso cup or transferred to another cup such as a cappuccino cup.
The caffeine content of an espresso cup varies depending on the type of coffee and how it is processed. On average, espresso contains about 25 to 30 mg of caffeine per 100 ml, which means that a single espresso serving in a cup contains about 10 to 12 mg of caffeine. Espresso and the thick-walled cups that go with it originated in Italy, where the drink is known as "caffè". These cups are still widely used in Italian coffee bars today and are often served with a glass of water.Esp
