A mocha is a chocolate-flavored warm beverage that is a variant of a caffè latte, commonly served in a glass rather than a mug. It is made by combining espresso, steamed milk, and chocolate, typically in the form of cocoa powder and sugar. The name "mocha" is derived from the city of Mokha, Yemen, which was one of the centers of early coffee trade. The drink gained popularity in Europe during the 17th century, where it became a fashionable beverage for the wealthy and aristocratic classes. Although a mocha is often interpreted differently across the world, the basis is that a shot of espresso is combined with chocolate powder or syrup, followed by milk or cream. Mocha is a versatile drink, and you can customize it according to your liking. You can use different types of chocolate, such as dark, milk, or white, to change the flavor profile. You can also add other flavorings like vanilla or caramel to enhance the taste.
