Kofola
Kofola is a carbonated soft drink produced by the eponymous Czech company, which is headquartered in Krnov, Czech Republic. It is the principal rival of Coca-Cola and Pepsi in the Czech Republic and Slovakia. The company is one of the leading soft drink producers and distributors in Central and Eastern Europe. Kofola originated in the Czechoslovak Research Institute of Medicinal Plants in Prague in 1959, during research targeted at finding a possible use for surplus caffeine produced in the process of coffee roasting. The resulting dark-coloured, sweet-and-sour syrup Kofo became the main ingredient of a new soft drink named Kofola, introduced in 1960. During the 1960s and 1970s, Kofola became exceedingly popular in communist Czechoslovakia, successfully competing with Western cola drinks like Coca-Cola or Pepsi, which were generally available after 1968 (Pepsi in 1974), but were expensive and considered as for high society. Even today, Kofola is a popular option in restaurants as it can be draught-poured from kegs right into a glass. Since 1998, Kofola has been bottled (in addition to classic 0.33-litre glass bottles) in 0.5-litre and 2-litre plastic bottles. 0.25-litre cans were introduced in 2003, and 1-litre plastic-bottles in December 2004. Kofola draught from 50-litre kegs, traditionally sold in many bars and restaurants across the two countries, remains popular as well.
