What is the main difference between a Grande Strawberry Acai Refresher and a Tall Strawberry Acai Refresher?

The main difference between a Grande Strawberry Acai Refresher and a Tall Strawberry Acai Refresher is indeed the size of the drink. In Starbucks, a Tall size is 12 fluid ounces, while a Grande size is 16 fluid ounces. This size variation directly impacts the overall volume of the drink, which includes all components such as water, juice, and ice. Because the Grande is larger, it typically contains a greater amount of all ingredients proportionately than the Tall, leading to a more substantial serving.

While the amounts of juice, ice, and any added fruit, such as strawberries, can vary depending on the specific customization of each drink, the primary distinction between the Tall and Grande versions is their size.
