Starbucks Sunsera Blend is remarkably versatile. Its a smooth, flavorful hot brewed coffee in Starbucks cafs both when its served black or customized at the condiment bar with milk and sugar. And it produces a beautiful cup of hot or iced coffee at home, with every brew method. We explored all the different ways that a customer would brew this coffee at home, Wolford said. Its just as great as iced coffee and cold brew.
