A mocha combines coffee, chocolate and milk. Compared with an espresso macchiato, chocolate is the defining addition: it changes the sweetness, flavour and texture of the finished drink.
Nespresso’s mocha guide describes the combination of espresso, chocolate and milk. Chocolate sauce, cocoa powder and different chocolate products need different preparation, so choose the exact ingredient before writing the recipe.
How to compare a mochaStart with your espresso recipe. Mix the chocolate ingredient into the coffee as its instructions require, add the prepared milk and record the finished cup size. Taste the whole drink, including any topping, before deciding whether to change the coffee, milk or sweetness.
For a café trial, list the amount of each ingredient and the preparation steps. A chocolate-heavy drink can taste very different from one that uses less chocolate, even when both are called mocha.
