Pure lump natural charcoal is the only thing to cook with. It gives you the best flavor and won't add any bad tast to your BBQ. We carry Seven Oaks Pure Lump Natural Charcoal. It is made from the best hardwood. Natural Lump charcoal burns hotter, cleaner and last longer than lump charcoals. At the Fireplace & BBQ Center we stock the Seven Oaks charcoal and many other smoke woods. We even carry many smoke woods that you can't get in the Des Moines area.
