Temperature control is one of the most important factors in cold smoking. To keep smoker temperature below 110°F, open the intake damper and chimney by just half an inch.
Ideally, cold smoking is better done in the fall and winter months when the air temperature is below 40 degrees. The cold air outside keeps it from getting too hot inside the smoker. If you can’t wait for cooler weather, smoke at night or early in the morning when temperatures are lowest. If the outside temperature is above 90°F, place a large aluminum drip pan filled with ice in the smoke chamber between the firebox and the food to keep the temperature low.
