Cigar Humidors: Why 20°C & 70% RH Alone Isn’t Enough

Every summer challenges cigar aficionados—forcing us to balance both temperature and humidity for optimal preservation. So, what’s the ideal environment? While 20°C and 70% RH is the golden rule, it’s not universal.

Cigars are living products. Proper storage awakens their potential, and your humidor is the key to nurturing them.


1. Gradual Humidity Adjustment is Critical

  • New cigars: Never place them loose in the humidor immediately. Store them in their original boxes until stabilized (typically 1–2 weeks).

  • Dry cigars:

    • Temporarily raise humidity to 75–80% RH for 1–2 days.

    • Gradually reduce to 70% RH.

  • Temperature compensation:

    • Lower temperature when raising humidity.

    • Raise temperature when lowering humidity.


2. High Heat = Pests & Mold Risks

  • Above 24°C:

    • Accelerates mold growth (common above 80% RH).

    • Triggers tobacco beetle infestations.

    • Causes bitter flavors.

  • Below 16°C:

    • Halts aging.

    • Dries out cigars.


3. Aging Strategies & Rotation

PurposeTemperatureHumidityRotation
Fast aging (1–3 months)21°C (70°F)72–75% RHNot needed
Mid-term storage (6+ months)23°C (73°F)65–68% RHFlip monthly
Vintage preservation16–18°C (61–64°F)62–65% RHFlip quarterly

Rotate cigars gently to ensure even humidity exposure—but avoid excessive handling.


4. Choosing a Humidor: Tech Comparison

A. Construction

  • Essential: Spanish cedar interior.

  • Exterior: Material irrelevant (wood/metal/glass all work).

B. Cooling Systems

TypeMax TempProsCons
Thermoelectric18°C (64°F)Affordable, quietLoses effectiveness in heat
Compressor22°C (72°F)Reliable, powerfulPricier, louder

C. Airflow Design

  • Direct-cool (evaporator):

    • Stable humidity   Uneven temperatures.

  • Fan-cooled (air circulation):

    • Even temperatures   Humidity fluctuations.


5. Storage: Avoid Flavor Mixing!

  • Never store different profiles together.

  • Solutions:

    • Use separate humidors.

    • Install divided cedar trays within one unit.


Summer Pro Tips

  1. Before opening the humidor:

    • Run AC to lower room temperature/humidity.

    • Prevents condensation on the door.

  2. Check for condensation:

    • Wipe the rear interior wall weekly—moisture buildup damages cigars.


Key Takeaway:
Mastering cigar storage means adapting to seasons, cigar types, and equipment limits. Ditch the "set and forget" mindset—your cigars deserve vigilance.
