Coca-Cola has entered the energy drink market with its first energy drink listed under the Coca-Cola brand. Taking on Red Bull and Monster, Coca-Cola Energy combines naturally derived caffeine, B vitamins and guarana extracts to create a beverage that has more than three times the caffeine of Coke. However, the decision has caused some controversy with Monster of whom it has a 16.7 percent stake in. Monster and Coca-Cola are in the middle of arbitration over the new release with Monster claiming that the new drink violates the agreement made between the two companies back in 2015. While Coca-Cola had previously developed energy drinks such as NOS and Relentless, they were transferred to Monster as part of the original agreement. Coca-Cola Energy will debut in Hungary and Spain in April.
