Quick answer
Brisket whole packer smokes at 225°F for about 75 minutes per pound. A 10–18 lb cut takes 12h 30m–22h 30m plus a 60-minute rest. Pull at 203°F internal. Wrap in butcher paper or foil at 165°F internal to push through the stall.

About brisket whole packer
The whole packer brisket is the brisket as it comes off the cow: flat and point still joined by a fat seam, untrimmed. Weights run 10–18 pounds, and it's the best brisket value at the meat counter — cheaper per pound than buying either half separately, and the point's fat protects the flat from drying out during the long cook. This is what serious pitmasters cook. The trade-off is volume: a 14-pound packer yields about 8 pounds of cooked meat, which is more than most families can use at once. Leftovers freeze well and reheat better than you'd expect.
Buying brisket whole packer
Look for flexibility — the packer should fold over your hand when you pick it up. A stiff brisket has hard fat that won't render. The flat should be thick and uniform, not tapered. Choice is acceptable, Prime is significantly better. At Costco and similar warehouse stores, packer briskets are routinely Choice grade at competitive prices.
Technique and pitfalls
Trim the fat cap to 1/4 inch over the flat side, slightly thicker over the point. Remove the hard waxy deckle fat between the two muscles. Square off thin edges. Apply salt-and-pepper rub the night before. Smoke at 225°F fat-cap up (heat conducts upward through the fat to protect the meat). Probe in the flat — that's the slower-cooking section. Wrap at 165°F internal in butcher paper. Pull when the flat probes tender at 203–205°F. Rest at least one hour, ideally three to four, in a dry cooler. Slice the flat against its grain, rotate 90 degrees, slice the point against its grain (or cube it for burnt ends).
Internal temperature and wrap timing
Pull the brisket whole packer when the thickest part hits 203°F on a probe thermometer. Probe-tender — the probe slides in like warm butter — is the more reliable signal than temperature alone; some cuts finish a few degrees above or below the target depending on the individual piece.
Wrap the brisket whole packer in pink butcher paper or foil when the internal temperature reaches 165°F. Wrapping stops evaporative cooling and pushes the meat through the stall — that 4–6 hour plateau around 165°F where temperature stops climbing. Pink butcher paper preserves more bark than foil; foil is faster.
Best wood for brisket whole packer
Post oak is the gold standard. Hickory and pecan work well. Avoid mesquite for a cook this long.
Common mistakes
Cooking a whole packer in a smoker that's too small — the meat needs to lie flat, not curl up. Trying to slice the flat and point with the same orientation; they have different grain directions. Pulling because of time rather than probe-tenderness.

Frequently asked
How long does it take to smoke brisket whole packer at 225°F?
About 75 minutes per pound at 225°F. A 10 lb takes ~12h 30m; a 18 lb takes ~22h 30m. Add a 60-minute minimum rest. Always pull at internal temperature, not by clock.
What internal temperature should brisket whole packer reach?
Pull at 203°F internal temperature, measured in the thickest part with a probe thermometer. Do not rely on cooking time alone.
Should I wrap brisket whole packer during the smoke?
Yes — wrap at 165°F internal in butcher paper or foil to push through the stall.
How long should brisket whole packer rest after smoking?
Rest at least 60 minutes wrapped, ideally longer for larger cuts. Resting redistributes juices and finishes carryover cooking. Slicing early dries the meat.
What is the best wood for smoking brisket whole packer?
Post oak is the gold standard.
