What volume is indicated for milk when preparing a tall frappuccino?

When preparing a tall frappuccino, the volume indicated for milk is at the bottom line of the blending cup. This guideline is important for achieving the right consistency and flavor balance in the frappuccino. Using the bottom line ensures that you are adding the correct amount of milk to provide the desired creaminess while maintaining the proper ice-to-liquid ratio. This is essential for blending the drink to perfection, allowing it to achieve the right texture. Recognizing the appropriate measurement point is key in crafting beverages consistently according to Starbucks standards.
