Belgian charcoal is a very high quality and clean burning charcoal. Belgian Charcoal is among the most popular coals in Europe. The 40mm discs are the longest burning of any disc charcoal making it super convenient and economical. These charcoals do not have any chemicals of any kind and thus require a constant heat source to light, such as a propane torch, hot plate, stove, grill, etc. After a Belgian Charcoal disc is fully lit, it burns hot and clean and does not alter the taste of the tobacco as does most other quick light coals.
