My bad, been in a meat coma for 4 days. hah.
I've done many briskets on my offset wood smoker (posted lots of meat porn in here in the past like other Surly brothers).
Wood stick burners give the best bark imo....some pellet guys may say they can get it too, but friends I have always produce a reddish color bark on their pellet grills.
I use a mustard binder (always have). Coarse pepper also helps with the bark/color....lots....I use 60% P (Fiesta brand at Academy) and 40%S (kosher). I season about an hour before going on the pit. I have found same results even if I season the night before and fridge store.
Smoke with oak and some apple at 225-300 degs. It's really not that important to hold steady at one temp...I used to drive myself crazy thinking I had to maintain 225-250. My pit has two doors so I keep the brisket by the left door (by the stack and furthest from the offset fire box).
I used to stick probes to monitor the meat during the entire cook, but after many you just have a feel for it. So I let it smoke 10-12 hrs depending on the size, and then I probe to see where it's at. If the bark looks good and I am around 150-160 internal temp, then it's time to Texas Crutch.
I Crutch with HD foil. Before wrapping the brisket I add in some DosXX or other mex beer (pour it under the brisket not on it). You don't have to do this, but it's one of those things I have ALWAYS done and feel like I might jinx it by not doing it ya know lol. I insert a probe into the flat, and wrap it as tight as possible. Toss it back on the smoker or oven (which I found is easier). You already got all the smoke flavor you can get after 10-12 hrs....why waste wood and monitor the pit when you can set oven to 250 and set it in a pan wrapped in foil. I go with oven method a lot.
I have tried using the pink butcher paper, but I can't add in my beer bc it will soak through. Some say the bark isn't crispy when using foil, but I don't really want crispy bark...I want brisket to melt in my mouth. To each their own, both ways are great. Or you can not wrap...but takes forever.
At 198-200 degs I take it out and unwrap to probe other areas for tenderness and temp. But feel is more important because all briskets are different and temp isn't enough to go on. If it doesn't feel right put it back in the cooker.
When it's ready, I let it rest on counter with foil pulled back for at least 1 hr. Gotta let it rest!!!! Don't cut it too early. If I don't need to serve it for hours I keep it wrapped in the foil and a towel...toss it in my yeti. The pics I posted recently...I pulled that brisket out at midnight...put it in the Yeti....and served it 12 hrs later. Still warm and tender as hell.
