Red Bull released Red Bull Cola, a 100 percent natural cola. Red Bull Cola has no preservatives, phosphoric acid or artificial flavors. The cola contains kola nut, coca leaf and slightly more caffeine than a traditional cola. Red Bull Cola is not a new kind of energy drink or an energy drink with the flavor of cola, the company says. It is a cola beverage and will compete in the soft drink category, the company explains. Red Bull Cola initially will be launched in seven countries, including the United States, in June, with a release in Las Vegas. Domestically, the cola will be available in 8.4-ounce cans in bars, restaurants and nightclubs. In grocery and convenience stores, it will be available in 12-ounce cans and four-packs.
