When you order a freddo cappuccino in Greece, you'll be asked about the sweetness level. This is because the sweetener is added by the barista when the coffee is still warm in order to dissolve better. The most common level of sweetness are: "Sketo" which means plain and it doesn't include any sweetener. "Metrio" which means medium. Usually you add 2 teaspoons sugar or the equivalent sweetener. "Gliko" which means sweet. This refers to a freddo cappuccino with 4 teaspoons sugar or the equivalent sweetener.
