Plank up your grilling experience with Afire Gourmet Grilling Planks We’ve taken plank grilling to a new level of subtlety and sophistication. Afire hardwood planks enhance and enliven food, without overpowering like Mesquite can. All Afire grilling planks are sustainably harvested and hand picked. We work with local tree farmers, selecting our wood from the mature trees. We also use wood from smaller trees to prevent them from sapping nutrition needed by the bigger, stronger trees.
