For a Venti teavana shaken iced peach green tea, what is filled to the bottom line of the shaker?

For a Venti Teavana Shaken Iced Peach Green Tea, the correct filling to the bottom line of the shaker is green tea. This beverage primarily consists of green tea as its base, which is combined with peach essence, and then shaken with ice to create a refreshing drink. The green tea not only contributes to the flavor profile but also provides the characteristic tannins and subtle earthiness associated with this type of tea.

In this drink preparation, the green tea acts as the core ingredient that unifies the other flavors—peach and ice—creating a balanced beverage. It's important to accurately measure green tea to ensure the right strength and flavor in the final drink. Other options involve different ingredients that are not suitable for this specific tea composition. For instance, water would dilute the flavor rather than enhancing it, while lemonade and pineapple juice introduce different taste profiles that do not align with the intended flavor of a peach green tea.
