Which drink requires the largest number of scoops of matcha when made as a venti?

The drink that requires the largest number of scoops of matcha when made as a venti is indeed the venti iced Teavana green tea latte. When preparing this beverage, the standard serving size for matcha is typically one scoop for a tall, two scoops for a grande, and three scoops for a venti. Therefore, because the venti size is the largest, it necessitates the highest amount of matcha compared to the other options presented.

In contrast, the tall iced classic chai tea latte uses a different base and does not involve matcha at all, making it irrelevant in this comparison. The tall and grande iced Teavana green tea lattes require fewer scoops, with only one scoop for the tall and two scoops for the grande, which further clarifies that the venti iced Teavana green tea latte indeed requires the most matcha. This distinction highlights the increase in scoop measurements corresponding to drink size within Starbucks’ offerings.
