Cigars
In short
Cigars keep best at 65 to 70 percent relative humidity and 18 to 21 °C (64 to 70 °F), in the dark and away from heaters, sun and odors. Without a humidor that only works for a few days, or in an airtight container with a two-way humidifier. The fridge is no substitute.
A cigar is dried, rolled tobacco leaf that takes moisture from the air and gives it back. To stay supple and burn evenly, it needs a climate that changes little. The values match our guide on humidity in a humidor.
| Target | Why | |
|---|---|---|
| Humidity | 65 to 70 % | below that the wrapper dries out; above 75 % the draw gets heavy and mold becomes a risk |
| Temperature | 18 to 21 °C (64 to 70 °F) | above 24 °C (75 °F) tobacco beetles become active, and relative humidity shifts with every degree |
| Light | dark | direct sun heats up the box and what's inside |
| Surroundings | odor-free | tobacco picks up smells, for example from the kitchen, cleaning products or perfume |
| Stability | as steady as possible | a spot away from heaters, windows and fireplaces keeps the climate calm |
An analog hygrometer may be off by a few percentage points. As long as the reading sits steadily between 65 and 72 percent, everything is fine.
A normal room is almost always too dry for cigars, especially during the heating season. How long things go well without a humidor therefore depends mostly on the container.
| Storage | Good for | Watch out for |
|---|---|---|
| Cellophane sleeve or box in the room | a few days | the sleeve slows drying but doesn't stop it |
| Freezer bag with a two-way humidifier | travel, short gaps | seal the bag tightly; the humidifier must not touch the cigars |
| Airtight container with a two-way humidifier and hygrometer | longer periods too | check and replace the humidifier regularly, read the value |
| Humidor | long term | seasoned, tight-sealing, with humidifier and hygrometer |
A two-way humidifier is a pouch that holds a set value: if the air is too dry it releases moisture, if it is too humid it absorbs it. For cigars, levels around 65 to 70 percent are common. In an airtight plastic or glass container that doesn't give off odors, it makes a small stand-in humidor. A hygrometer inside the container shows whether the humidifier is still working.
An empty wooden box without humidification, on the other hand, is not a humidor. The wood buffers for a while but dries out along with the cigars.
No. A fridge is far colder than the 18 to 21 °C range, its humidity can't be set, and food gives off odors that the tobacco absorbs. When you take a cold cigar out, moisture from the warm room air also condenses on it.
A wine cooler is a different matter: it holds an adjustable temperature without food next to it. It doesn't regulate humidity for cigars, though. If you use one, you need your own humidification, such as two-way humidifiers, plus a hygrometer, and you set the temperature to 18 to 21 °C.
Some collectors use the freezer for one purpose only: a tobacco beetle infestation. The cigars are sealed airtight and, after freezing, brought back to room temperature slowly so that no water condenses on them. It is not meant for storage.
Temperature and humidity are linked. Warm air can hold more water, so with the same amount of water a hygrometer shows a lower reading in a warmer room. If the humidity drops suddenly, check the thermometer first before adding water.
A good spot is an interior wall in a room with an even temperature: not on the windowsill, not above the heater, not next to the fireplace. A basement is often cooler and more humid than the living space; there it pays to watch the hygrometer closely for the first few weeks.
In a well-kept humidor, a very long time. Many aficionados deliberately store cigars for years because the flavor keeps developing. What matters is not the time but that the climate is right throughout. Without a humidor, every day a cigar sits too dry counts.
How to tell its condition: a well-stored cigar gives a little under light pressure and springs back. If the wrapper crackles or cracks, it is too dry. If it feels spongy and draws heavily, it is too moist. You can only bring a dried-out cigar back slowly: first in a somewhat drier environment, then in the humidor. Humidifying too fast makes the wrapper split.
The most common causes are a humidifier put in too wet, a freshly seasoned humidor whose wood is still saturated, and very humid room air. Before you act, check the hygrometer with the salt test: sometimes the air isn't too humid, the reading is just wrong.

Tobacor is a care tool for any humidor, whatever the brand. The app works with the values you read off your hygrometer.

For a few days the cellophane sleeve in a cool, dark spot is enough. For longer, use an airtight container with a two-way humidifier and a hygrometer. A wooden box without humidification dries out along with the cigars.
No. The fridge is too cold, its humidity can't be set, and food gives off odors that the tobacco absorbs. When you take a cigar out, moisture also condenses on the cold wrapper.
At 18 to 21 °C (64 to 70 °F) and 65 to 70 percent relative humidity. Above 24 °C (75 °F) tobacco beetles become active. A spot away from heaters, windows and fireplaces keeps the temperature even.
In a well-kept humidor, a very long time; many people deliberately store cigars for years because the flavor matures. Without a humidor, they dry out noticeably in a room within a few days.
First check the hygrometer with the salt test. If the reading is right, take out the humidifier, dry it off and leave the lid open for one to two hours. A two-way humidifier also absorbs excess moisture by itself.
