Just got done was 1st brisket and it was awful, I know what they mean by dry as she leather. I have the new cabelas pellet smoker made by pit boss. I preheated to 250 and threw the brisket on (16 lb pre-trimmed) at 4 am. By 6am I was approaching 160 and turned it down to 220. By 7am I was 180 and at 8am nearing 190. I checked for tender and it was not ready yet. At 11am it was between 205-210 and tender on the probe. I wrapped it in butcher paper and towels and threw it in the cooler for 5hrs and cut it at 4pm. It was so tough and dry I could hardly cut it. It felt nice and tender when I pulled it. Did it set to long? I planned on about 14 hrs but this was done in half that? I am questioning the temp my grill was reading. I did have 2 small water pans in the cook chamber too.
Hi there and welcome!
I'm guessing the Internal Temp (IT) of your brisket was not measured accurately.
I run 3 meat probes with my HeaterMeter on my briskets because I have found that it is nearly IMPOSSIBLE to get an accurate IT on a brisket with a single or even 2 meat probes!
The thickest part of the flat is the best but but it takes me 3 probes to get it right hahaha.
After watching how all 3 probes go up at drastically different rates and how each one will/can overtake the lead on the other two multiple times, I understand how people have issues with cooking briskets.
I often have a probe reading at like 210F, one at 206F, and the final one at 202F when the final tenderness check tells me that the brisket is tender all over. The wrong angle, a fat vein, and any other human or natural error can throw off a brisket IT quite a bit in my experience.
Just keep at it, probe the crap out of it, and when it is truly butter consistency tender ALL OVER then you know you are good to go or at least not undercooked where you get dry and tough meat.
I hope this info helps :)
