Formula
Raw Weight = (Guests x 0.5 lb) / 0.60 | Cook Time = Weight x Hours/lb (by temp)
Brisket size is calculated based on 0.5 pounds of cooked meat per person, adjusted for 40% shrinkage during smoking. Cooking time is estimated using hours-per-pound rates that vary with smoker temperature: 1.5-2 hrs/lb at 225F, 1-1.5 hrs/lb at 250F, 0.75-1 hr/lb at 275F, and 0.5-0.75 hrs/lb at 300F.
Worked Examples
Example 1: BBQ for 12 Guests at 250 Degrees F
Problem:Calculate brisket size and cooking time for 12 guests, smoking at 250 degrees F.
Solution:Cooked meat needed: 12 guests x 0.5 lb = 6 lbs cooked. Raw weight needed: 6 lbs / 0.60 (40% shrinkage) = 10 lbs raw. Cooking time at 250F: 1-1.5 hours per pound. Min: 10 x 1 = 10 hours. Max: 10 x 1.5 = 15 hours. Average: 12.5 hours. Rest time: 1 hour. Total average: 13.5 hours.
Result:Brisket: 10 lbs raw | Cook time: 10-15 hours | Rest: 1 hour | Total: ~13.5 hours
Example 2: Large Party Brisket at 225 Degrees F
Problem:Calculate brisket needs for 25 guests, low-and-slow at 225 degrees F.
Solution:Cooked meat needed: 25 x 0.5 = 12.5 lbs cooked. Raw weight: 12.5 / 0.60 = 20.8 lbs raw (round to 21 lbs, may need 2 briskets). Cooking time at 225F: 1.5-2 hours per pound. For a 14-lb brisket: 21-28 hours. Rest: 2 hours. Consider two 11-lb briskets for more manageable cooking.
Result:Need ~21 lbs raw (2 briskets recommended) | Cook: 16-22 hours each | Rest: 2 hours
Frequently Asked Questions
How much brisket do I need per person?
The general rule for brisket is to plan for one-half pound of cooked brisket per person for a main course serving. However, since brisket loses approximately 40 percent of its raw weight during the long smoking process due to moisture evaporation and fat rendering, you need to start with significantly more raw meat. A good planning formula is about 0.8 to 1 pound of raw brisket per person. For a group of 10, you would need approximately 8 to 10 pounds of raw brisket. If your guests are big eaters, or if brisket is the only protein being served, plan for closer to 1 pound of raw weight per person. Always round up because leftover brisket reheats beautifully.
What temperature should I smoke a brisket?
The most common and recommended smoking temperature for brisket is 250 degrees Fahrenheit, which provides a good balance between cooking speed and tenderness. Lower temperatures around 225 degrees Fahrenheit produce incredibly tender results but significantly increase cooking time, often requiring 1.5 to 2 hours per pound. Higher temperatures around 275 to 300 degrees Fahrenheit reduce cooking time but require more attention to prevent the exterior from drying out. Aaron Franklin, widely considered one of the best brisket pitmasters in the world, smokes his briskets at 250 to 275 degrees Fahrenheit. The key is maintaining a consistent temperature throughout the cook, avoiding large swings that can toughen the meat.
What is the brisket stall and how do I handle it?
The brisket stall is a phenomenon that occurs when the internal temperature of the brisket plateaus around 150 to 170 degrees Fahrenheit and stops rising for several hours, sometimes up to 6 hours. This happens because moisture evaporating from the surface of the brisket cools it at the same rate the smoker heats it, similar to how sweating cools your body. The most popular solution is the Texas crutch, which involves wrapping the brisket tightly in butcher paper or aluminum foil once it reaches the stall temperature. Wrapping traps moisture and prevents evaporative cooling, pushing the internal temperature through the stall zone in 1 to 2 hours instead of 4 to 6. Many pitmasters prefer butcher paper over foil because it is breathable and maintains better bark texture.
How do I know when a brisket is done?
A brisket is done when its internal temperature reaches 195 to 205 degrees Fahrenheit, with 203 degrees being the sweet spot most pitmasters target. However, temperature alone is not the only indicator. The probe test is equally important: when you insert a thermometer probe or toothpick into the thickest part of the brisket, it should slide in with the ease of pushing into warm butter, meeting very little resistance. If there is resistance, the collagen has not fully rendered and the brisket needs more time. The flat and the point sections of a whole packer brisket may finish at different times because they have different thicknesses and fat content. Always test in multiple spots to ensure even doneness throughout.
