What type of milk is used to top a Grande iced skinny flavored latte?

A Grande iced skinny flavored latte is designed to be a lower-calorie option without sacrificing flavor. The "skinny" aspect indicates that nonfat milk is typically used as the base and in the preparation of these drinks. Nonfat milk provides the creaminess and texture desired in a latte while keeping the calorie count lower compared to whole milk or even alternatives like soy or almond milk.

Moreover, the choice of nonfat milk aligns with Starbucks' intention to cater to customers looking for healthier options. The flavored syrup added to the latte complements the nonfat milk, ensuring that the beverage remains flavorful and satisfying. Hence, nonfat milk is the correct choice for this specific drink.
