Manufacturer's Brand Overview: [Edit]
A popular sweet drink in Brazil made from the extract of a red berry that grows in Venezuela and Northern Brazil and is high in caffeine, guarana originally got off to a slow start in the U.S. PepsiCo Inc. (PEP) introduced its own version of guarana, called Josta, in 1997 in the U.S., but discontinued it when it didn't sell in large volume. Guarana has gained popularity in the U.S. since then, along with other beverages that provide caffeine or energy boosts, such as energy drinks and sports drinks.
