Every cigar aficionado — whether an old hand or a total novice — must address the challenge of cigar storage as their collection grows beyond what they can reasonably smoke in a few weeks. Storing cigars at the right temperature and humidity is crucial for their longevity, and maintaining these conditions can be a challenge.
The challenge of temperature control varies depending on where in the USA you live. With climates ranging from high humidity to desert dryness, and extreme heat to freezing cold, maintaining the ideal environment for cigars requires careful attention and some experimentation.
The 70/70 Rule
When it comes to cigar storage — whether in a compact desktop humidor or a large walk-in humidor for businesses — the goal is to replicate the conditions where the cigars were made. For cigars originating from the Caribbean, that means warm and humid conditions. The rule of thumb is to follow the 70/70 rule: 70 degrees Fahrenheit and 70% relative humidity.
This stable environment preserves your cigars in prime condition, ensuring they remain flavorful and free of damage from insects, mold, or decay. A quality humidor usually comes equipped with a humidifying device to maintain proper moisture levels. This can range from simple sponges soaked in distilled water to advanced digital hygrometers that automatically control humidity and airflow.
But temperature control often gets overlooked, and that can be a costly mistake for maintaining your cigars.
The Importance of Temperature Control in Your Humidor
Temperature control is just as crucial as humidity, and here are four key reasons why:
Tobacco Beetles
Tobacco beetles are a nightmare for cigar collectors. These insects lay eggs in tobacco leaves, and while the eggs are harmless when dormant, higher temperatures can trigger hatching. The larvae will then feed on the cigars, potentially destroying your entire collection.
Tobacco beetles thrive in environments above 74°F. To prevent infestations, maintain your humidor between 68°F and 70°F.
Mold and Mildew
Mold and mildew are ever-present threats. They thrive in warm, moist conditions, and a too-hot humidor is the perfect breeding ground. Keeping the temperature steady and cool helps protect your cigars from fungal growth.
Flavor and Aroma
Temperature extremes can ruin the flavor and aroma of your cigars. High temperatures degrade essential oils in the tobacco, while freezing temperatures can cause ice crystals to form, leading to dry and brittle cigars. Maintaining a steady, moderate temperature is key to preserving the premium qualities of your collection.
Relative Humidity
Temperature and humidity are interconnected. A sudden increase in temperature lowers the relative humidity unless adjustments are made. Conversely, a drop in temperature can cause humidity levels to spike. Stable temperature control ensures consistent humidity, preserving your cigars in optimal condition.
Ways to Keep Your Humidor at 70 Degrees
Now that you understand the importance of maintaining a steady temperature, here are some practical tips for keeping your humidor at the ideal 70°F:
Keep Your Humidor Out of Direct Sunlight
Direct sunlight can cause temperature fluctuations and degrade the essential oils in your cigars. Even indirect sunlight can raise the temperature inside your humidor. Position it in a shaded, temperature-stable area.
Avoid Heating and Air Conditioning Vents
Heating and cooling vents can create drafts and temperature swings that disrupt the balance inside your humidor. Place your humidor far from HVAC registers and avoid exterior walls that may experience temperature variations.
Utilize a Basement
If you live in a warm climate, a basement can provide naturally cooler temperatures year-round. Basements insulated by the surrounding earth are particularly stable, making them ideal for cigar storage in the South. However, in colder climates, basements may be too chilly.
Use an Ice Pack
During extreme heat, you can place an ice pack on top of your humidor, covered with a towel to prevent condensation. This is a temporary solution but can help maintain acceptable temperatures during heatwaves.
Adjust the Cooler Function
In colder months, cigar coolers may over-chill your collection. Turn off the cooling function if temperatures drop too low. Regularly monitor your humidor to ensure it stays within the desired range.
What About Cold Climates?
While most advice focuses on cooling humidors, cigar enthusiasts in cold climates face a different challenge: warming their humidor to 70°F. Cold environments can disrupt humidity levels, leading to musty or dry cigars.
Investing in a humidor with a built-in heating function, like the NewAir CC100H, is a great solution. This model maintains a perfect 70°F regardless of the season, with a tight seal and a hygrometer for precise control.
Conclusion
Temperature control is just as vital as humidity when it comes to preserving your cigars. Whether you're battling summer heat or winter cold, monitoring your humidor and making necessary adjustments will keep your collection in top condition. By maintaining stable conditions, you can enjoy flavorful, perfectly aged cigars all year long.
