This is good quality lump, and a bargain to boot. It is comparable to BGE lump in quality, It is nearly all useable sizes, with pieces averaging about 3". Just a little dust in the bottom of the bag, along with a few chips. You will not find any unburned pieces of wood, and no funny stuff. A few pieces included bark, maybe 3-4 in the entire bag. There was some scrap, but nothing fancy. The lump lights easily and quickly, and does not smoke excessively. It had a light woodsy, smokey aroma that added flavor but did not overpower delicate foods. Ozark Oak is perfect for grilling and gets hot very fast to sear steaks.
