What is the base milk method used for all the drinks listed?

The base milk method used for all the drinks listed is steamed milk. In Starbucks, many espresso-based beverages, such as lattes and cappuccinos, rely on steamed milk as their foundational ingredient. Steamed milk not only adds a creamy texture to these drinks but also enhances the overall flavor profile by allowing the sweetness of the milk to blend harmoniously with the espresso.

When properly steamed, the milk develops microfoam, which is crucial for creating the desired consistency and presentation in drinks like lattes and flat whites. This technique not only contributes to the taste but also affects the visual appeal of the beverage, as the microfoam can be artfully poured to create latte art.

Other types of milk, such as cream, coconut milk, or cold milk, might be used in specific drinks or alternatives but do not serve as the standard base for the majority of steamed drinks on the menu. Steamed milk is integral in both crafting the texture and providing the classic taste that customers expect in many of Starbucks' offerings.
