Here's the Naked Whiz review;
"This is some nice lump. It is manufactured by Royal Oak for Big Green Egg. We have heard rumors that Royal Oak saves their best lump for BGE. We have reviewed Royal Oak's own brand and found it to be as good as the BGE lump. This bag consisted of mostly usable sized pieces, very few chips and little dust. We found some unburned pieces, but probably only 8-10. Some of the lump comes from the edges sawn off of logs. You could see saw marks on one side and bark on the other. This was by far, the most bark we've seen so far, but then it appears to be all good wood, some the edges from a lumber mill. Some people don't like bark and claim it has a bitter flavor, so if you are one of them, you might want to pick through the lump to get the bark out. As for smell, this lump has a very mild smokey smell, less strong that, say, Maple Leaf.
One other word about what we found in the bag. Check out the photos and you'll see we found some funky looking rainbow pieces. These pieces were definitely the same type of wood as the rest of the bag. We believe that some pieces, depending on whatever, come out this way. However, these pieces were NOT pine or some other funky wood that you wouldn't want in your grill.
Also, since this lump is made by Royal Oak, you might wish to read the review of Royal Oak for more information. Normally, we don't take the price into account in rating lump charcoal since it can often vary greatly depending on where you buy it. However, Big Green Egg lump is consistently one of the most expensive charcoals on the market. Considering you can get the same charcoal from Royal Oak at half the price, we feel this knocks this charcoal down a notch to our Recommended rating."
