For a (Grande) Caramel Macchiato, how much syrup is used?

In a Grande Caramel Macchiato, the standard amount of vanilla syrup used is indeed 4 pumps. This amount is essential for achieving the balance of flavors that defines this beverage. The sweetness of the vanilla syrup complements the espresso and the creamy milk, while the caramel drizzle on top adds an extra layer of flavor, enhancing the overall taste profile.

Using too little syrup would lead to a beverage that tastes predominantly of milk and espresso, lacking the characteristic sweetness that many customers expect from a Caramel Macchiato. Therefore, the use of 4 pumps of syrup is crucial to maintain the drink's signature flavor.
