Here is another thing to keep in mind also.
The temp that most people wrap at is 165, and that is really not some magic number like 195-205 is. The stall starts around 150, so that would actually be the time to wrap. However most competition pit masters cook at 250 or 275, and the meat will get to 150 IT in about 4 hours. And there in lies the problem. 4 hours is not enough time to build a good bark and have it set properly, so they take it to 5 or 6 hours, and the temp will be close to 165 by then. That’s really where that recommended 165 temp comes from.
Since many in this forum use Matt Pittmans overnight method, it isn’t necessary to wait until the IT is 165 to wrap. When that brisket has cooked overnight, even at a low temp, the bark is gonna be set in the morning, and you can actually save yourself some time by wrapping immediately.
If you watch Matt’s video, you will see that he wraps at 7 am, without knowing what the IT is, and he comments that the bark looks good, and wraps it. No probes in the meat, and he doesn’t use a Thermapen either. In his follow up comments he mentions that he wrapped at 165 IT (or whatever).
Any of us that have done the overnight method and started at 7 pm at 190 degrees knows there is no way the IT of that 15 pounder was 165 at 7 am.
Sooo, if you use the overnight method you can probably have that puppy ready for a late lunch if you want to. And, that’s using low temps (180-190 overnight, 225-250 after the wrap). Especially if you are gonna use foil...
