Primo 100 percent all-natural lump charcoal 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 Primo All-Natural Lump Charcoal with your Primo 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. For best results in flavor and quality, use Primo Natural Lump Charcoal with your Primo Ceramic Kamado Style Grill and Smoker.
