The Calories in a Starbucks Tazo Green Tea Frappuccino

Starbucks' signature Frappuccino blended beverages are available in numerous inventive flavor combinations. For example, the Tazo Green Tea Crème Frappuccino mixes powdered matcha green tea with milk and ice, and customers can also request whipped cream atop the finished concoction.

General Calories

Tazo Green Tea Crème Frappuccinos come in three traditional Starbucks sizes. The standard version made with whole milk supplies 240 calories in a 12 oz. tall, 330 calories in a 16 oz. grande and 440 calories in a 24 oz. venti. Those calorie counts are substantially less than an average thick vanilla milkshake, which contains approximately 382, 510 and 765 calories in 12 oz., 16 oz. and 24 oz. servings, respectively, according to the U.S. Department of Agriculture.

Milk Variations

Customers can tailor Tazo Green Tea Crème Frappuccinos to their personal preferences and dietary needs. Ordering one with 2 percent or soy milk instead of whole milk reduces the calories in the beverage by roughly 15 calories, while nonfat milk saves you about 40 calories.

Other Calorie Considerations

The optional sweetened whipped cream topping also has a significant impact on the total amount of calories in a Tazo Green Tea Crème Frappuccino. Requesting one with the garnish adds 80 calories to a 12 oz. serving and 110 calories to 16 oz. and 24 oz. servings.
