Big Green egg painstakingly sources our natural charcoal to ensure that it contains no fillers, nitrates, chemicals, treated wood or petroleum products. Unlike briquettes, pure and natural Big Green egg charcoal is premium carbonized wood with no additives whatsoever. Big Green egg oak and hickory charcoal is made in the USA from 100% natural hardwood. It is easy-to light and is usually ready for cooking in a few minutes and burns hotter and more efficiently than charcoal briquettes. Lump charcoal produces less ash, so there is minimal waste and clean-up delivering value in every bag.
