How It Works

How to Estimate Smoking Time

Formula

Time (min) = Base Rate (min/lb) x Weight x (225 / Smoker Temp)

Base rates are approximate minutes per pound at 225°F. Higher smoker temperatures reduce the time proportionally.

Target Internal Temperatures

  • Brisket: 200-205°F (until probe-tender)
  • Pork shoulder: 195-205°F
  • Pork ribs: 190-200°F (or bend test)
  • Whole chicken: 165°F in the thickest part of the thigh
  • Turkey: 165°F in the thigh
  • Salmon: 145°F

    • Rest Time

    Always rest large cuts for 30-60 minutes (wrapped in foil and towels) after smoking. The internal temperature will rise 5-10°F during the rest.

    Worked Example

    A 12-lb brisket at 225°F smoker temperature.

    meat_type = 90weight_lbs = 12smoker_temp = 225
    1. 01Base rate = 90 min/lb for brisket
    2. 02Time = 90 x 12 x (225/225) = 1080 min = 18 hours
    3. 03Start 19 hours before serving (includes 1 hour rest)
    4. 04Monitor internal temperature; pull at 200-205°F.

    Frequently Asked Questions

    What is the stall?

    The stall occurs when the meat internal temperature plateaus around 150-170°F for several hours. Moisture evaporation from the meat surface cools it at the same rate the smoker heats it. You can wrap in foil or butcher paper to push through faster.

    What wood should I use?

    Hickory and oak are versatile all-purpose woods. Fruit woods (apple, cherry) are milder and pair well with pork and poultry. Mesquite is very strong and best in small amounts or for quick smokes. Never use softwoods (pine, cedar) as they produce toxic resins.

    How much wood do I need?

    For charcoal smokers, plan on 2-4 fist-sized chunks of wood for a long cook. For stick burners, plan about 1 split per hour. The goal is thin blue smoke, not billowing white smoke which tastes bitter.
