Ans: Mostly, we use food-grade wood pellets in a pellet grill. But won’t use heating pellets designed for pellet stoves, as they contain toxins and chemicals that poison your food. So, food-grade wood pellets are cheap and widely used. However, they come with a lot of different flavors, yet the most common ones are…. • Maple • Cherry • Hickory • Oak • Apple • Alder • Pecan • Mesquite Each flavor of this wood pellet will slightly have a different flavor on the food and you can figure out and use pellets to cook your favorite food. Also, use different types of pellets to enjoy different flavors. Test the different flavors before buying a full bag.
