Big Green Egg painstakingly sources natural charcoal to ensure that it contains no fillers, nitrates, chemicals, anthracite coal, limestone, treated wood or petroleum products. Unlike some of the other charcoals and briquettes, pure and natural Big Green Egg charcoal is premium carbonized wood with no additives whatsoever. Contains only 100% natural American oak and hickory “ultra premium” hardwood … you will see — and taste — the difference immediately. Easy to light and is usually ready to cook in about 10 minutes. It burns hotter and more efficiently, with more BTUs, than charcoal briquettes. Produces less ash so there is minimal waste and clean up. Food tastes better without harsh chemicals or odors that can be released when cooking with briquettes or other similar products. Manufactured in the USA. 20 pound bag.
