FAQ
How long does it take to smoke a brisket per pound?
At 250°F, budget about 1 hour 20 minutes per pound, plus at least an hour of rest before slicing. A 14 lb packer runs roughly 18-19 hours total including rest. Lower pit temps take longer; higher temps run faster but with more risk of drying out the flat.
What smoker temperature should I use?
250°F is the most common target and what this calculator’s rule of thumb is built around. Running at 225°F stretches the cook longer but gives you a bit more margin for error; 275°F speeds things up if you’re tight on time, but leaves less room to recover from a bad stall.
What’s “the stall,” and does this calculator account for it?
The stall is a plateau, usually somewhere in the 150-170°F internal range, where evaporative cooling can hold the brisket’s temperature flat for an hour or more. The per-pound estimate already factors in typical stall behavior, but every brisket stalls a little differently, so treat the calculator’s time as your target, not a guarantee, and start checking internal temp rather than just watching the clock as you get close.
Should I build in extra buffer time?
Yes. Brisket is far more forgiving of finishing early than finishing late, since a finished brisket holds well wrapped in a cooler for a couple of hours. Start earlier than the calculator suggests if you have any flexibility, especially for a brisket over 14 lbs or a first-time cook on a new smoker.
Does wrapping in butcher paper or foil change the timeline?
Yes, wrapping generally speeds up the back half of the cook by trapping heat and moisture. Butcher paper shaves off roughly 10% of total cook time versus leaving it unwrapped; foil trims closer to 18%. This calculator’s estimate assumes a typical wrap partway through, so an unwrapped (“naked”) cook will run longer than the estimate.
What’s the difference between this calculator and the Brisket Cook & Hold Calculator?
This one tells you when to start smoking so the brisket finishes around your target time. The Cook & Hold Calculator goes further, working backward from your serving time to also tell you how long to hold the finished brisket in a sous vide bath, which is the more precise option if you want an exact serving time instead of a finish-time estimate.
