What is the syrup pump count for a Trenta Americano?

For a Trenta Americano, the syrup pump count is zero because this beverage is primarily comprised of espresso and hot water. The Americano is meant to enhance the robust, rich flavor of the espresso itself, without the addition of flavored syrups. While other beverages might typically include syrup to augment sweetness or flavor, the Americano's standard preparation does not include any syrup, allowing the true espresso taste to shine.

In contrast, other drink sizes or types may have one or more pumps of syrup to balance flavors or add sweetness, but in this case for the Trenta Americano, the absence of syrup is the correct approach.
