Already the top performers in the ready-to-drink (RTD) energy coffee subcategory, Starbucks Doubleshot Energy+Coffee beverages will soon be available in a new flavor: Cinnamon Dulce.

Cinnamon Dulce combines the subtly spicy taste of cinnamon and vanilla with a supercharged blend of Starbucks coffee, B-vitamins, guarana, and ginseng. Cinnamon Dulce will be available in grocery and convenience channels alongside existing Coffee, Mocha, and Vanilla flavors in early February 2009. The existing flavors already occupy three spots in the top five drinks in their category.
