What should the water or lemonade be filled to in the shaker for the Trenta Teavana Shaken Iced Peach Green Tea?

For the Trenta Teavana Shaken Iced Peach Green Tea, the water or lemonade should be filled to the middle line in the shaker. This guideline is essential for achieving the right balance of flavors and ensuring that the drink is properly mixed. Filling the shaker to the middle line allows for enough space for the ice and the tea concentrate to combine effectively while also ensuring that the drink is not overly diluted. It's crucial that the proportions are correct so that the resulting beverage maintains the intended taste profile, which includes the refreshing notes of peach and the subtlety of green tea.

Other filling levels, such as the bottom or top line, would not provide the necessary balance for optimal flavor—either resulting in an overly concentrated or overly diluted drink, thus impacting the quality of the final product served to customers.
