We've been using a pellet grill for a couple of years. When we first got it I bought a bag each of hickory, apple, pecan, and a "Classic" blend bag of hickory, pecan and mesquite. We
have decided there is not one bit of identifiable difference between any of them, so now we only buy the blend. The exception being, when we cold smoke cheese I use BBQrs Delight 100%
Apple pellets in the smoker tube. (At $12 per pound it SHOULD be 100% apple!!) There seems to be a lot of discussion online about cooking pellets and just how much of the "flavored wood" and
how much and what type of filler is used in them. I certainly do not claim to be a pellet expert, but those are my unsolicited thoughts!
