Lotoko, also known by the slang term "pétrole", is a home-distilled alcoholic drink or "moonshine" in the Democratic Republic of the Congo. Lotoko is usually made from maize, but sometimes from cassava or plantain. Heads of corn are cut up and boiled into a mash which is then fermented and distilled using improvised stills made from cut down oil drums. Although it is officially banned, because of its high alcohol content (over 50%), its production is widespread in the Democratic Republic of Congo.
