KEO is a Cypriot beer. It is a light straw-colored lager with a thick head, and is sometimes compared to a pilsner in taste. The beer is brewed in Limassol, in Cyprus. The beer won the 1987 brewing industry world bottled lager competition Gold Medal.
In 2010, KEO held a 32.4% share of the island's beer market.
Currently, its ingredients include malted barley, maize, and hops, but maize is a new addition.
In 2010 the appearance of the beer in a pornographic American film sparked a reaction by the largest shareholder in the company, the Orthodox Church of Cyprus.
