My sense of smell must be stronger than my palate because it smells like a delicious chocolate berry smoothie I used to make but it just tastes like standard green tea. I agree that it would be lovely with a side of chocolate.
Update: Some turbinado sugar helps bring out the flavor and there is definitely a lingering flavorful aftertaste.
Double update: After the 4th cup of pondering where I’d smelled this before it finally hit me. Chocolate strawberry bubble tea! I was madly obsessed with that stuff in college.
