How many pumps of mocha sauce are needed for a Grande chocolate milk?

A Grande chocolate milk at Starbucks typically requires a specific amount of mocha sauce to achieve the desired flavor balance. For a Grande size, which is 16 ounces, the standard amount of mocha sauce used is four pumps. This amount ensures that the chocolate flavor is not too overpowering but still present enough to satisfy the drink's intended taste profile. Using four pumps results in a rich yet balanced chocolate milk that customers expect when ordering this drink.

Thus, choosing four pumps as the answer aligns with the established standards used in crafting Starbucks beverages, especially for signature drinks like chocolate milk that rely on specific measurements for flavor consistency.
