Cold-smoke cured bacon for 12-24 hours, cured ham intermittently for 2-5 days after a 4-6 week cure, sausage for 12-48 hours, heavily brined fish for 12-24 hours and cheese for 2-4 hours, only in cool weather below 60°F, and only after the meat’s cure is finished. These are the parent article’s schedules and describe the smoke time, not the preservation: the cure is what keeps the meat.
Part of Large-Scale Smoking & Curing
A cold-smoke schedule is the length and pattern of smoking applied to a salt-cured product at temperatures that flavour it without cooking.
The Schedule Depends On The Product
The parent article gives these cold smoke schedules:
| Product | Smoke time | Notes |
|---|---|---|
| Bacon | 12-24 hours | after dry cure |
| Ham | 2-5 days, intermittent | 8-12 hours smoking, 12 hours rest, after a 4-6 week cure |
| Sausage | 12-48 hours | depends on type |
| Fish | 12-24 hours | after heavy brine |
| Cheese | 2-4 hours | no curing needed |
Ambient temperature should be below 60°F; early morning is ideal. In warm climates cold smoking is only practical in late fall through early spring.
Reading the ham schedule. Taking the parent as one smoke-and-rest cycle per day, each cycle is 8-12 hours of smoke plus 12 hours of rest, 20-24 hours in all. Two days is then 2 × 8 = 16 hours of smoke at minimum; five days is 5 × 12 = 60 hours at maximum. The total smoke time for a ham therefore runs from about 16 to 60 hours, and the product sits at ambient temperature through the rests. The wording is ambiguous, so check how a sample piece looks and tastes before applying it to a whole batch.
How to judge a finished piece. The smoke time is a guide to flavour and colour. The surface should be dry, evenly coloured and slightly tacky-hard. A piece that is wet, slimy or smells sour is not finished; it is spoiling.
What You Need
- Meat whose cure has been completed (Curing times by thickness)
- A cold smoke setup that holds below 85°F (Below-85°F smoke generation)
- A cool-weather window, with ambient air under 60°F
- A log of times, temperatures and weather
Method: Run The Schedule
Step 1: Check the cure is complete and rinse and dry the surface until tacky.
Step 2: Hang with space, and start the fire small.
Step 3: Smoke for the period in the schedule, logging chamber temperature at intervals. Stop if it nears 85°F.
Step 4: For ham, rest for 12 hours between periods with the vent set to hold the chamber cool.
Step 5: Move finished pieces to cool, dry hanging storage (Hanging storage and pest prevention).
Common Mistakes
- Smoking before the cure is finished. The interior is unprotected for days at smoking temperatures.
- Smoking in a warm spell. The chamber exceeds 85°F.
- Treating more smoke as more preservation. Beyond flavour, extra smoke time adds little protection that the cure did not already provide.
- Skipping the rest periods for ham. The chamber warms and the surface case-hardens.
Safety
A long cold smoke is a long time in the growth range for bacteria
Cold smoking holds meat at roughly 60-85°F for hours or days, within the 40-140°F range where bacteria multiply (USDA; recalled). Only a finished cure makes this safe. If the cure used nitrite or saltpetre, do not smoke a batch whose cure you cannot vouch for (Cold-smoked sausages and bacon covers the nitrite hazard). Discard any piece that is slimy, sour, or discoloured through its centre.
