Cigar Upkeep: How Do Cigar Humidifiers Work? - Your Elegant Bar

January 29, 2021 11 min read

The role humidor humidifiers play in maintaining the quality of cigars is vital to your overall smoking experience. A cigar humidifier ensures the moisture's stability inside your humidor cabinet, and getting a good cigar puff is impossible if it did not come from a well-maintained humidor.

How Cigar Humidifiers Work

Since cigars are made of natural tobacco with no added chemical preservatives or artificial components, some extra care must be taken to preserve the flavor and quality of your cigars. A cigar that’s kept too damp or too dry, too hot or too cold, may not burn or taste as well as it could. Proper storage could also prevent molding, dampening, or the loss of a cigar’s essential oils. That’s where a humidor comes in.

Cigars and humidor

Activating your humidor is the initial step to establish optimal conditions for your cigars, and this can be done using a sponge or crystal system. The sponge system uses propylene glycol solution and distilled water for adequate humidification performance and needs weekly refills to function properly. Maintaining just the right moisture level in a cigar humidor can be achieved by following the humidification’s suitable mechanism.

Meanwhile, the crystalhumidification system is moderately new and is only used by a small number of manufacturers. Its crystalline, embryonic structures make for a good alternative to sponge since it continually works on the clock and only requires monthly refills.

How Do You Humidify a Cigar Humidor?

Humidifying the humidor entails keeping the air quality clean and increasing its moisture content. The humidification process helps create homeostasis of the airway, making it ideal for your cigars to maintain their natural components for a long time. 

Cigar humidor humidifiers come with water filtration systems that need to be refilled or replaced, but some models nowadays are more advanced and automatically refill the humidifier’s cartridge.

Some cigar humidifier systems come in flora foam, crystal gel, silica beads, or humidity packets, all of which vary according to maintenance and application to the humidifier. Moisture is stored and released providing consistent humidity. Another option is an electric humidifier. An electric humidifier will maintain humidity on its own. This means no more weekly water refills.

Humidifier Solution: Propylene Glycol Solution

Traditional humidors adopt a mechanism that uses plastic or metal that has a sponge as a humidifier. It contains a special fluid called Propylene Glycol Solution that helps sustain a humidifier’s lifespan while preserving the cigars’ freshness. 

The PG Humidifier solution consists of 50% distilled water and 50% food-grade propylene glycol, which play a role in keeping the RH at 70%. This system also boasts antifungal and anti-mold properties, which come in 8 oz. bottles that can last up to 9 to 12 months if used properly.

How to Season a Humidor with a Humidifier Solution

Step 1:Open your cigar humidor. Using a soft cloth, apply distilled water until it’s a bit damp. Wipe the interiors of the humidor but ensure not to leave it soaked. Wipe it down thoroughly. 

Step 2: Close the humidor’s lid for a few hours. Grab the propylene glycol solution and place it in a bowl of distilled water. Let the sponge absorb the water and wait a few seconds, then remove it from the bowl. Shake properly to remove excess water, then place it back inside the humidor.

Step 3:Place your cigar humidor in a spot away from sunlight to ensure external heat does not impact the humidification process.

A hygrometer is a device found in your humidor that allows you to monitor the cigars’ humidity levels without having to open and close it every time. Significantly, hygrometers measure the box’s relative humidity and warn you when the humidifier requires recharging or adjustments.

The standard setting is at 70% humid and a temperature placed at 21.1 degrees Celsius. Hygrometers come in digital or analog, which should be checked at least once a week to help build a consistent environment for your precious cigars.

So, How Does a Humidor Work?

Pretty simply, really. Once you’ve seasoned and prepared your humidor, place your cigars inside. It’s recommended that you store different types of cigars separate from one another so that their flavors do not mingle. The humidifier inside your humidor will help keep the humidity at the right level. 

You’ll also want to store your humidor in a location that stays around 70 degrees and is out of direct sunlight. Once you’ve found the right location, all you need to do is replace the water in your humidor as needed. Check your hygrometer to make sure everything looks good. If you’re worried about large temperature fluctuations, you might consider anelectric cigar humidor cabinet.

How Long Can You Keep a Cigar in a Humidor?

The short answer, about five years. That’s assuming you’ve got everything dialed. If your hygrometer wasn’t calibrated properly or you don’t maintain humidity, then your cigars won’t last as long. You can of course keep your cigars in your humidor for longer. The flavors will develop up to a certain point, but it’s not a never-ending cycle. A cigar that’s ten years old won’t necessarily taste better than a cigar that’s five years old. 

Read the cigar maker’s suggestions, ask at your local shop, or talk with friends to estimate how long a cigar should be aged for. Generally all cigars should be aged for some period of time, but whether peak flavor occurs at two years or five years is dependent on the cigar.  If you have a whole box of a certain type of cigar, smoke one every six months or so. Note how the flavor has changed. If the flavor continues improving, continue aging. Let your taste buds be your guide.

Electric Humidor Humidifiers

Perhaps the best way to secure your cigar collection and keep them in tip-top shape is to invest in an electronic cigar humidifier. Several types, such as ultrasonic humidifiers, emit a cool mist using ultrasonic vibration, while evaporative humidifiers use a powerful fan to blow air through a wet wick or filter.

Now that you know how to use a humidor, below are some of the best cigar humidor humidifiers that amateur enthusiasts and long-time tobacco collectors should consider buying.
