This innovative drink from Starbucks Japan combines the bold richness of espresso with the smooth, floral notes of Tieguanyin, a premium variety of Chinese oolong tea. Known for its lightly roasted aroma and naturally sweet finish, Tieguanyin (also called “Iron Goddess of Mercy”) adds an elegant tea depth to the creamy milk base. The result is a well-balanced latte with a unique fusion of earthy, floral tea and roasted coffee smooth, mellow, and refreshing in every chilled sip.
