A custom blend of hardwood manufactured entirely from whole wood pieces rather than slab wood like most lump charcoal. Broil King Keg charcoal is an optimal mix of 1 to 3-inch size lumps which burn long and produce very little ash. Broil King 100 percent all-natural lump charcoal (TCF5506) is the premium choice fuel for grills and smokers. This environmentally-friendly special blend of charcoal is free of tars and other harmful chemicals. It lights faster, burns hotter and longer, and produces less ash than traditional briquette style charcoal. When using this Broil King All-Natural Lump Charcoal with your Broil King Kamado Style Grill, a single load can be reused multiple times when cooking low and slow, and it can burn for up to 36 hours! Add even more flavor by combining with your favorite seasoned wood chips or chunks like mesquite, apple, and hickory.
