A barbecue grill is a device for cooking food by applying heat directly from below. There are several varieties of such grills, with most falling into one of two categories: gas-fueled and charcoal. There is a great debate over the merits of charcoal or gas for use as the cooking method between barbecue grillers. Barbecuing is a pervasive tradition in much of the world. Almost all competition grillers use charcoal, most often in large, custom designed brick or steel grills.
