Red Bull is the brand name of an energy drink that originated in Thailand and, in a version adapted to Austrian tastes, is now popular throughout the world. Sold by Red Bull GmbH as an energy drink to combat mental and physical fatigue, it contains, per 250 ml (8.3 U.S. fl. oz.) serving, about 21.5 g sucrose, 5.25 g of glucose, 50 mg of inositol, 1000 mg of taurine, 600 mg of glucuronolactone, vitamin B --20 mg of Niacin, 5 mg of Vitamin B6, 5 mg of Pantothenic Acid and .005 mg of Vitamin B12-- and 80 mg of caffeine. The caffeine in one serving is similar to that found in an average cup of brewed coffee (typically 100 mg/250 ml cup, but 72 mg for a U.S. regular 6 fluid ounces cup of coffee) or twice as much as found in a can of Coke (40 mg/330 ml can). A sugar-free version has been available since the beginning of 2003. Sugar-free Red Bull is sweetened with aspartame and acesulfame potassium, as opposed to sucrose and glucose.
The drink is intended to taste like mixed berries, and is commonly used as mixer in alcoholic drinks such as vodka and is the base ingredient in the now famous Jägerbomb and Remytini. Almost 1 billion of the slim 250 ml cans were sold in 2000 in over 100 countries, 260 million of them in the UK. In 2006, more than 3 billion cans were sold in over 130 countries. 3,903 employees generated 2.6 billion euros in turnover.
