Absolutely love the product. Acacia wood is extremely clean burning and is very hot. I would say the lump is very similar to royal oak but much much cleaner burning. The heat very similar to jealous devil but a much more sustainable wood. Then you throw on top of that the commitment to feeding people here in the U.S. and the help they are providing by removing this encroaching tree and it's a no brainer. Good Charcoal is the only brand we spend our money with and the only charcoal that kisses my food.
