All of our wood chunks are thoroughly dried and 100% all-natural… NO additives. Our wood chunks have had all bitter tree bark removed to ensure you're getting maximum smoke of 100% all natural wood. The wood chunks are BIGGER, CHUNKIER, pieces of wood perfect for grilling and barbecuing. The wood chunks are perfect for use in our Gas Smoker Cooker and Wide Gas Smoker Cooker. All bags are 1.75 LB bags (794 g), 242 cu.in., 3.96 L in size. Since 1968, Smokehouse Products has been smoking wood chunks in our smokers. It is a tradition to come together with family and friends to share the heritage of producing only the best smoked foods. It is time we share it with you.
