i would say about 11/2 chimneys worth give or take a few coals
Thanks for the replies. Trying to calculate out how much. I will need for the next few long cooks.
You need to stock up and then it won't matter. If you're even semi serious about cooking with charcoal, you need to take advantage of the summer holiday specials on KBB and stock up. It may seem silly at first, but a couple to a dozen to a pallet of KBB in your garage is just a good way to save money if you buy in bulk on sale. Give some thought to how much you'll need for a year and how much storage you have and try to get enough for a year.
Ken, a full ring should make it 10 hours pretty easily. I can usually get 13-14 hours with 2 large butts on board with a full ring.
