How many pumps of vanilla are typically used in a 12oz. latte?

In a typical 12oz. latte, the standard practice is to use four pumps of vanilla syrup. This quantity strikes a balance between enhancing the flavor without overpowering the coffee. The four pumps provide a noticeable sweetness and vanilla essence that complements the espresso and steamed milk, resulting in a well-rounded drink profile that appeals to most customers.

Using fewer pumps, like two or three, may result in a less flavorful beverage that may not meet customer expectations for a vanilla latte. On the other hand, using five pumps could make the drink excessively sweet, potentially overwhelming the other flavors. Therefore, four pumps is the ideal amount to achieve the right flavor balance in a 12oz. latte.
