Ideal Relative Humidity for Cigar Humidors
The ideal relative humidity for cigar humidors is generally between 65% to 70%.
What happens if humidity is too high?
If a humidor stays above 72% relative humidity, cigars can become too moist, making them difficult to light and draw. Worse, sustained high humidity can lead to mold growth or hatch tobacco beetles.
What happens if humidity is too low?
Below 65%, the essential oils in the tobacco evaporate. The cigar will dry out, the wrapper may crack or unravel, and the smoke will become harsh and burn too quickly.
Frequently Asked Questions
- What is the 70/70 rule?
- The 70/70 rule is a classic guideline suggesting cigars should be stored at 70°F and 70% relative humidity. However, many modern aficionados prefer 65% RH to prevent burn issues.
- How do I season a new humidor?
- Before storing cigars, the cedar wood inside a new humidor must absorb moisture. You season it by lightly wiping the interior with distilled water and leaving a sponge with distilled water inside for 24-48 hours.
