Proper Humidity
Proper humidity is the cornerstone of cigar storage. It refers to maintaining a stable relative humidity (RH) level—typically between 65% and 70%—to preserve a cigar’s flavor, structure, burn quality, and overall integrity. Deviations outside this range can lead to cracked wrappers, poor combustion, flavor loss, or even mold and beetle infestations.
Whether you're storing cigars short-term or aging them over years, controlling humidity is non-negotiable.
Why Humidity Matters
Cigars are hygroscopic, meaning they absorb and release moisture based on their environment. If the ambient humidity is too low or too high, it affects:
- Burn consistency
- Draw quality
- Wrapper integrity
- Flavor clarity
- Cigar lifespan
Even the finest cigars will underperform or deteriorate if not stored in the correct RH range.
“Proper humidity isn't optional—it's essential. Even premium cigars will fail under poor conditions.”

Ideal Humidity Range for Cigars
| Humidity % (RH) | Outcome |
| Below 60% | Cigars dry out, crack, and lose flavor |
| 62–65% | Aging zone; preferred for long-term aging |
| 65–70% | Optimal range for most cigars |
| 70–72% | Acceptable for short-term storage |
| Above 72% | Risk of mold, swelling, and poor draw |
Sweet spot: 65–69% RH with 65–70°F (18–21°C) temperature
Signs Your Humidity Is Off
Under-Humidified Cigars:
- Dry, cracking wrapper
- Harsh, bitter flavor
- Fast, uneven burn
- Feels light or brittle to the touch
Over-Humidified Cigars:
- Tight draw or plugged airflow
- Swollen wrappers that crack when cut
- Musty smell or early signs of mold
- Feels overly soft or spongy
How to Maintain Proper Humidity
- Use a reliable humidor lined with Spanish cedar
- Monitor RH with a calibrated digital hygrometer
- Use two-way humidification systems like Boveda packs or crystal gel jars
- Store the humidor in a cool, dark, and stable environment
- Avoid opening the humidor frequently—especially in dry climates
- Rotate cigars occasionally to ensure even exposure

Humidity & Cigar Type
Some cigars perform better with slight adjustments:
- Thick-ring cigars often prefer 65–66% RH for optimal draw
-
Delicate wrappers like Connecticut Shade benefit from 68–70% RH
-
Aging full-bodied cigars? Keep them closer to 62–64% RH for longer-term storage

Summary
Maintaining proper humidity is the single most important factor in cigar preservation. It’s not just about keeping cigars “fresh”—it’s about ensuring they deliver the full spectrum of flavor, aroma, and craftsmanship they were designed for. By staying within the 65–70% RH range and using the right tools, you give every cigar the chance to shine.
