What type of milk is used in all the frappuccinos mentioned?

The correct answer indicates that frappuccinos are made with milk added to a specified line on the blender or cup. This means that the milk used can vary based on individual preferences or specifications for the drink. When crafting a frappuccino, baristas are trained to fill the milk to a specific line in the container, ensuring that the beverage is prepared with the right consistency of liquid, which is crucial for achieving the desired texture and taste.

This method allows for flexibility in terms of milk types as customers can typically request different kinds of milk, such as whole milk, 2% milk, or even non-dairy options like almond milk, according to their dietary needs or preferences. Hence, using milk to the specified line accommodates a variety of milk choices while maintaining the quality of the beverage.
