What type of beverage is "White base" used in?

The correct choice is that "White base" is used in coffee blends. In the context of beverage preparation, particularly in coffee specialty drinks, a white base refers to a creamy, milk-based mixture that is typically used to enhance the texture and flavor profile of various coffee beverages. This base often combines milk or cream with other ingredients to create a smooth, rich mouthfeel.

Coffee blends benefit from the white base as it allows for versatility in flavor combinations and can improve overall consistency in the finished drink. It can help balance the robustness of coffee with sweetness and creaminess, appealing to customers who enjoy lattes, cappuccinos, and other espresso-based drinks that require milk integration.

While tea infusions, milkshakes, and fruit smoothies may involve creamy elements or bases, they have distinct preparation methods and specific ingredients that do not typically include a "white base" in the same context as coffee beverages. Milkshakes focus on ice cream and flavorings, while fruit smoothies primarily emphasize fruits, yogurt, or other dairy products. Therefore, understanding the context and application of a white base is crucial for mastering beverage preparation in coffee-related applications.
