Four Loko

Four Loko is a line of alcoholic beverages sold by Phusion Projects of Chicago, Illinois, United States. Four Loko's previous recipe included caffeine. Phusion operates as Drink Four Brewing Company. Four Loko, the company's most popular beverage, debuted in the United States market in 2005 and is available in 49 states, and in 21 countries including Ecuador, Guatemala, Paraguay, The Bahamas, Peru, Mexico, Colombia, Bolivia, Honduras, El Salvador, Nicaragua, Costa Rica, China, Canada and some countries in Europe. The name "Four" is derived from the original drink having four "key ingredients".

Four-branded products have been the object of legal, ethical, and health concerns related to the company allegedly marketing them to underage drinkers and the danger of combining alcohol and caffeine. After the beverage was banned in several states, a product reintroduction in December 2010 removed caffeine, taurine, and guarana as ingredients, and the malt beverage is no longer marketed as an energy drink. As of January 2026, Four Loko is still in business and producing carbonated malt beverages with sucrose and artificial coloring. The current Four Loko flavors include Sour Apple, LOKO USA, Jungle Juice, Peach, CAMO, Sour Blue Razz and Fruit Punch.
