We use 100% natural wood chips to create our super-premium wood pellets for use in all pellet grills. We never use any perfumes, oils or artificial flavors. Instead, we rely on mother nature to give our awesome wood pellets the best flavor. Some competitors claim to sell species-specific hardwood pellets. However, it's very difficult to get a written guaranty from the manufacturer as to what the ingredients are. We use a combination of oak, hard maple, hickory and cherry woods, sourced directly from the forests of New England. We never use alder wood or gum tree in our pellets.
