Brisket questions come up constantly: why one from a smaller animal can weigh well under 10 pounds, what a "split" brisket is, and how to trim a whole packer for pastrami. For a barbecue restaurant, a deli or a meat counter heading into the holidays, the answers come down to the spec.
What a whole packer brisket is
A whole packer brisket is the full boneless brisket from one side of the animal, with both muscles attached:
- The flat: the larger, leaner, even-thickness muscle. Best for slicing, corned beef and pastrami.
- The point: the thicker, fattier muscle on top. Prized for burnt ends and chopped beef.
The common wholesale spec is IMPS 120, brisket, boneless, deckle-off. The deckle is the hard fat and lean on the rib-side surface, and removing it gives a cleaner piece.
Why brisket weights vary so much
A brisket's weight follows the carcass. Briskets from large, grain-fed cattle are heavier; briskets from smaller or grass-fed animals, or from custom processing, can be much lighter. A brisket well under 10 pounds from a smaller animal is not wrong. It came from that animal.
For a barbecue program, consistent size means consistent cook times, so name a weight range when you order.
What a "split" brisket means
Retailers use "split" in different ways. Sometimes it means the point and flat were separated. Sometimes it means a whole packer was cut in half, even lengthwise, so each piece has some point and some flat. Neither is a standard spec. If you need halves, say exactly how they should be cut.
Trimming brisket for pastrami and corned beef
Pastrami makers trim brisket a few ways:
- Whole packer, thin fat cap: about a quarter inch of fat cap left on, hard fat removed.
- Whole packer, closely trimmed: most external fat removed, for a leaner slice.
- Flat only: point removed and used for other items; the flat cures and slices evenly.
Most deli programs aim for a thin, even fat layer so the cure and smoke penetrate evenly and the slices hold together. Thick, hard fat blocks the cure and gets trimmed off; some soft fat stays for moisture.
Brisket buying checklist
- Spec: whole packer (IMPS 120) or flat only.
- Grade: Prime, Choice, Select or ungraded.
- Weight range per piece.
- Fat trim: untrimmed, or a maximum fat cap thickness.
- Pack: pieces per case and case weight.
Timing
Brisket demand rises around holidays and barbecue season. Watch the USDA boxed beef cutout on our USDA charts and the notes in USA Meats Intelligence, and check the holiday calendar when you plan corned beef and holiday features. For a delivered price on a pallet, use the landed-cost calculator.
A clear brisket spec keeps cook times, yields and slice quality the same from one case to the next.
