What is the recommended volume of milk for preparing a cappuccino?

The preparation of a classic cappuccino typically involves a balanced ratio of espresso, steamed milk, and milk foam. For a standard cappuccino, the recommended volume of milk is approximately 150 ml. This amount allows for the desired texture and richness without overwhelming the espresso flavor.

In a traditional cappuccino, the drink is usually made up of one-third espresso, one-third steamed milk, and one-third foam. Using around 150 ml of milk ensures that there is enough for both steaming and frothing, creating that signature creamy foam on top while maintaining the integrity of the espresso beneath it.

Other volumes may not provide the same balance; for instance, 100 ml could result in a drink that is too espresso-heavy, while larger volumes like 200 ml or 250 ml would dilute the espresso and alter the drink's intended flavor profile. Thus, 150 ml is the optimal choice for achieving a true cappuccino experience.
