I have a Brinkman vertical two door smoker and use a veggie wok for my coals. It works pretty good. Before I had just drilled tons of holes in the provided pan, but it didn't work that well. As for how much charcoal, I'm sure it depends on many factors. As I type I have an 8.48 lb brisket in my smoker that I started about 9 AM (MT). I have added coals once and it is now 1:24 PM. Still have a little of over 200 degrees. As for time, everyone says at least an hour per pound or so. I'm planning on at least 10 hours total. My last brisket turned out great and it was in for 10. Might have been around the same size. One thing I did was spray it with water every 45 mins or so. I seasoned mine with Brown Sugar, Garlic Salt, Onion Powder, Paprika, Cracked Black Pepper, Kosher Salt (because it's coarse) and a lot of love lol. I wanted to put it in Coca Cola because I understand it helps tenderize, but I'll try that another time. Maybe inject it or marinade it. This is my third brisket and it takes time, but it's well worth it. One thing to do is make sure you don't panic as it gets that charred look, you must check the internal temp. I'm thinking 180 or so will be good. We'll see at about 7PM. And be sure to cut it right, it makes a huge difference. I'm no pro, but I'm learning from the guys here. I'm originally from Texas and live in Idaho. We have a few (2) BBQ restaurants here, including a Famous Dave's. I still prefer my brisket to theirs. Whatever that's worth. And I don't need BBQ sauce on my brisket. Good luck. Thanks again to the folks here for helping me make one hell of a brisket.
