The Humidor as an Ecosystem

How cedar, humidity, air and cigars interact

A humidor is not simply a container for storing cigars. It is a living ecosystem, a controlled environment in which different elements interact with a single purpose: to preserve the cigar in the best possible condition over time.

Inside a humidor, four fundamental variables come into play: cedar wood, air, humidity and, of course, the cigars themselves. None of them works in isolation. They all influence one another, and only when they are in balance does the cigar remain stable and healthy.

The cigar, the center of the ecosystem

The most important element inside a humidor is the cigar. Once a cigar has been finished, banded and released to the market, it no longer matures in the strict sense; it simply ages over time. The purpose of a humidor is not to transform it, but to preserve it, preventing moisture loss, structural imbalances, aromatic alterations or combustion issues.

Our work as humidor makers is to create an environment in which the cigar remains stable, protected and as close as possible to the environmental conditions of its origin.

Cedar wood, its natural companion

From its very origin, tobacco coexists with cedar wood. From the curing barns or drying sheds, to the torcedor’s table, and finally to humidors and aging rooms, cedar is always present. This is no coincidence.

Cedar, whether Spanish cedar or bossé cedar, is a tropical wood accustomed to moderate temperatures and medium-to-high humidity levels, conditions very similar to those required by tobacco. It is a soft, porous and highly hygroscopic wood, capable of absorbing and releasing moisture gradually, acting as a natural regulator inside the humidor.

Moreover, the characteristic aroma we associate with a cigar does not come solely from the tobacco leaf itself, but from the cedar that surrounds it. Cedar provides aromatic identity and, at the same time, acts as a powerful natural insect repellent, protecting the tobacco organically against pests. This is why cedar and tobacco have always gone hand in hand.

Humidity and temperature, a physical balance

Humidity does not reside only in the cigar or in the wood, but also in the air that surrounds them. That air is the element that connects the entire ecosystem that a humidor becomes.

From a physical standpoint, it has been proven that tobacco behaves optimally at an absolute humidity of approximately 12.00–12.50 g/m³, which, when expressed as relative humidity, corresponds to roughly 70% relative humidity at 20 °C.

In the case of air, humidity is always expressed as relative humidity, as it indicates what percentage the actual amount of water vapor represents compared to the maximum the air can hold at a given temperature. For this reason, the same amount of water vapor can result in different relative humidity values depending on the air temperature.

For example, when working within a temperature range of 20 to 22 °C, that same absolute humidity translates into a relative humidity between 65% and 70%, which is the ideal range for reproducing optimal tobacco conditions in the air.

This is why, at Wacota, we understand that in the European context the ideal goal is to maintain, on an annual average, a temperature close to 20 °C and a relative humidity around 70%.

It is important to remember that the same relative humidity percentage does not imply the same amount of water if the temperature changes. Therefore, the percentage must be adjusted according to seasonal temperature variations. During winter months, temperatures are lower and relative humidity should be set higher; during summer, temperatures rise and relative humidity should be reduced accordingly.

If temperature drops, humidity must be adjusted upward.
If temperature rises, humidity must be adjusted downward.

It is pure physics: warm air can hold more water vapor than cold air.

Air and its circulation

A healthy ecosystem needs to breathe. Humid air, if kept completely stagnant, loses quality over time. That is why air circulation inside the humidor is essential.

A well-designed humidor naturally facilitates this circulation through its internal structure. When this is not possible, simply opening the humidor periodically allows for air exchange. This simple action helps distribute humidity evenly, renew the atmosphere and maintain internal balance.

Creating a habitat, not just a container

A good humidor does not impose artificial conditions on the cigar. It recreates its ideal habitat. A balanced combination of cedar wood, temperate air, controlled humidity and long-term stability.

When these four elements work together, the cigar is preserved, remains alive and expresses its full potential when the moment comes to enjoy it.

For us, this is the true meaning of the humidor as an ecosystem, and the principle on which we conceive each and every one of our humidors.
