Any input on better results to go 9 hrs at 250, then wrap at 250 versus maybe 12 plus hours at 180 then wrap and bump up? I've seen both and want to get a good tender one. Gonna use Pecan pellets.
Hi there and welcome!
Briskets are only done when they are tender. They are tender when you can stab ALL OVER with something like a kabob skewer and it goes in like the brisket was butter and the skewer was hot.
Briskets are NEVER finished by time or temp... only tenderness.
Now, you can use the brisket Internal Temp (IT) to indicate when to check for tenderness. I personally wait until an IT of 200F on Choice briskets and 198F on Prime briskets.
When you hit that temp, check for tenderness. If tender ALL OVER then pull it. If not then let IT raise another couple of degrees and test again. Pull when tender.
As for time, it matters but it will not tell you when your brisket is done.
In my smoker a brisket generally cooks at just a little over an hour a pound with my smoker running a steady 275F and the brisket unwrapped the entire time. I don't know the rough timeline at a smoker temp of 250F.
Get your estimated time at your target smoker temp figured out and then I highly recommend you add 4 hours to that planned time so you can ensure it has enough time to be done. If it finishes 4 hours early that is idea. You just tightly double wrap in foil, tightly wrap in 3 bath towels and set on the table and it will be piping hot and ready to slice 4 hours later. I promise.
If it doesn't finish 4 hours early... you have 4 extra hours to get the job done haha.
Wrapping the brisket is up to you. I do like the fact that you are wanting to wait until an IT of 180F to wrap. This would almost guarantee you don't wrap it too early and end up with a roast beef brisket flavor instead of a smoked brisket flavor :)
As mentioned in the previous post. Don't have any sugar in your rub/seasoning if running smoker at 250F+, you don't want to burn the sugar and waste a brisket. I got Salt, Pepper, Onion, Garlic (SPOG) and love it!
Your pecan pellets will be fine but your smoke flavor may be a bit weak. I would suggest Oak or some blend with Mesquite in it. Mesquite and beef simply cannot be beat.
Finally, place your meat probe in the thickest yet center most part of the FLAT muscle. Nowhere else. The FLAT muscle is the problem child and will be the last to get tender. The point is easy going and unless you burn it or pull the brisket way early, the point will be fine.
I hope all this info helps :)
