What is "enviga"

Enviga is a Nestea carbonated canned green-tea drink. Enviga is a trademark of Nestlé licensed to Beverage Partners Worldwide, a joint-venture between Coca-Cola Company and Nestlé. It is available in three flavors: Green tea, Tropical Pomegranate and Mixed Berry. According to Coca-Cola, Enviga burns 60 to 100 calories per three 12-oz.(330 ml) cans due to its high EGCG and caffeine content. This is disputed by some researchers and public advocates.
