The Definitive Guide to Cigar Humidors and Humidification

Whether you’re growing your cigar collection, investing in a box to age, or like to buy several cigars at once, you’ll need proper protection and storage for the smokes you’re not ready to puff on yet.

Premium smokes and collectables, like Cuban cigars, vintage batches and limited editions require proper humidification to keep them safe. Cigars certainly aren’t the cheapest thing in the world, so if you want to save a smoke for a special day, it’s a good idea to invest in a decent humidor.

The humidification process can be quite complicated, and plenty of enthusiasts don’t know how to properly store their precious cigars. Fear not, though; we have gathered our resident experts at Havana House to produce an extensive guide to cigar humidification.

Why do Cigars Need to be Kept in a Humidor?

Tobacco for cigars is grown and rolled in places like Cuba and the Dominican Republic, where temperature and humidity are considerably different from places like the UK. A humidor is needed to keep cigars at the optimum humidity level to smoke perfectly.

If a cigar is left in a place that is too humid, it will become damp. This damaging effect will make the cigar hard to draw smoke through and can impact the burn, causing a tunnelling effect and an excess of smoke.

On the other hand, if it is in too dry conditions, a cigar will lose its flavourful oils and have burn issues that cause it to smoke too fast and hot.

How to Choose a Good Humidor

When it comes to good cigar humidification, the first step is choosing a good humidor. Other than being functional, humidors are often used as ornaments and become the centrepiece of a room.

For this reason, you may want to choose a real spectacle of a humidor such as those hand-crafted and inlaid with marquetry. In addition to their beauty, humidors vary in function, depending on the components used to produce them.

Parts of a Humidor

A humidor is made of a number of parts, including the exterior wood, interior wood, humidification system and hygrometer.

Inner Lining of the Humidor

The inner lining of a humidor is the part that will be in closest contact with the cigars. Despite being an important part of the humidor, the wood lining is not always integral to the humidor you buy, as it can be replaced.

Often, aficionados will replace the innards of a humidor. Primarily, three types of wood are used for the humidor’s inner lining: Spanish Cedar, Red Cedar and Honduran Mahogany.

Spanish Cedar for Humidors

Spanish Cedar is commonly used for humidors as it has many benefits. This wood type can absorb a high level of humidity, ensuring that the climate inside the humidor is kept stable and free from mould development.

Spanish cedar has a distinct fragrance, which helps to keep away tobacco worms and protect the cigars in the humidor. It is also a great wood for supporting the ageing process of cigars, and its scent has a positive effect on flavour.

Red Cedar for Humidors

When it comes to humidity absorption, Red Cedar is an inferior material to Spanish Cedar. Some humidor manufacturers use this wood as it is less expensive and easier to acquire.

Red Cedar exudes a more intense aroma than Spanish Cedar, which can be both a pro and con. When storing cigars for long periods of time, a strong woody flavour can be imparted onto the cigars, so choosing Red Cedar will depend on if this is something you’d like for your ageing cigars.

Honduran Mahogany for Humidors

Honduran Mahogany has a humidity absorption rate comparable to that of Spanish Cedar, yet at the same time, the wood has a less intense odour.

Unfortunately, the deterrent effect on insects is greatly reduced, and the desired flavouring of the cigars is not as good as with Spanish Cedar.

Which Wood Is Best For Humidors?

At Havana House, we suggest that you choose a humidor lined with Spanish Cedar. The thickness of the lining you use is essential. Basically, the thicker, the better. A lining less than 2mm in depth will not take advantage of the beneficial characteristics that the wood provides.

Humidor

Should You Choose a Veneer or Solid Wood Humidor?

Essentially, there are two different options when constructing the exterior of the humidor. MDF, which stands for medium-density fiberboard or solid wood.

MDF consists of a veneer of some type of hardwood. Solid wood humidors will see the entire humidor crafted (often by hand) from a solid hardwood, such as Sycamore.

Is MDF or Solid Wood Better for Humidors?

Contrary to popular belief, solid wood humidors are not necessarily superior to veneer humidors. While solid wood humidors are thought of as heirloom-worthy and come across as more physically imposing, the construction of veneer humidors can actually prove more beneficial for the storage of cigars.

It all comes down to the strain of timber used to craft the humidor. MDF humidors are made to withstand changes in humidity. Since the moisture inside the humidor will be much higher than the external humidity, the internal wood tends to expand and crack parts of the structure. Timber gathered from trees that are suited to a humid, tropical environment are often immune to this.

Which Wood to Choose for a Humidor Box?

Examples of wood that is resistant to warping and cracking as a result of the change in humidity are – Mahogany, Ebony, Zebrawood, Bubinga and Rosewood.

Of course, there are plenty of woods that could be used, so it is important that you do your research beforehand. In addition to this factor, humidor wood should also be impermeable to help prevent insects laying their eggs inside and to give some added protection to splashes.

It is also an advantage for humidor wood to be hard and resistant to dents to extend the cigar box’s shelf life.

Characteristics of a Good Humidor

More things to inspect when looking for a humidor include:

  • Hinges – Should be durable and ensure low-friction functioning for many years to come.
  • Quality of lacquer application – A smooth and even application is key.
  • Airtight seal – Humidors should close so well that a constant level of internal humidity can be maintained.

Humidifiers for Cigars

Every humidor needs a humidifier of some sort. This is the element that keeps the humidity levels correct within the humidor.

What is the Optimum Humidity Level for Cigars?

Inside the humidor, cigars should be stored at a relative humidity of approximately 65-70% humidity.

In such an environment, the cigar should absorb the ideal rate of humidity of 14% of its weight. Typically, it is thought that the best flavours of a cigar can evolve in such a climate.

If you intend to store your cigars for a number of years, 65% is recommended. If you frequently smoke (every day), then 70% is optimal for taste.

Humidity Issues for Cigars

It should be noted that if one allows the humidity level to exceed 80%, then their cigars will begin to mould and rot.

If cigars become too dry, they become fragile and burn rather quickly. This not only causes a shorter smoke but allows the cigar to take on an aggressive and slightly bitter taste. On the other hand, a cigar that is too damp will burn unevenly and take on a heavy and acidic flavour.

Should You Use a Sponge or Crystal Humidifier for Cigars?

Until recently, all humidifiers employed the same simple mechanism. They were all equipped with a plastic or metal case containing a sponge as a humidifier.

Sponge Humidifier

Sponge humidifiers are soaked in water or a solution; Propylene Glycol 50/50 is recommended. The sponge is then placed in a plastic container and uses capillary action to bring the liquid to the surface and release it over time. Sponge humidifiers will need to be refilled every two weeks, or more if your cigars are feeling dry. The sponge itself is likely to need replacing yearly.

Overall, the simple sponge based humidification system provides sufficient humidification performance.

Crystal Humidifier

In more recent years, crystal humidification systems have become more popular. While humidors aren’t typically made with these systems yet, you can purchase crystal humidifiers as an extra that can be popped into the humidor instead of the sponge. These have been made popular by the brand Xikar.

The advantage of these systems is that they work constantly and only need to be refilled monthly as opposed to weekly. The release is slow and steady, maintaining consistent humidity levels by both emitting and absorbing moisture to keep the humidity at 70%, whereas humidity levels tend to fluctuate more when using a sponge.

Xikar’s crystal humidifiers can simply be recharged using the Propylene Glycol solution when needed.

Humidification Packs

Another option is Boveda humidor packs, which contain salt and purified water that is slowly released through reverse osmosis to provide perfect humidity. They can be purchased in a range of humidity levels (62, 65, 69, 75 and 84 percent), so you can pick the pack that best suits the needs of your cigar collection.

These packs are single-use and need replacing every three months or so; however, they are an affordable option, with packs starting from 85p each.

Hygrometers for Humidors

Hygrometers are small instruments that allow you to gauge the humidity of your humidor. Before use, hygrometers must be calibrated, and it is recommended that they are recalibrated around once a year to maintain their accuracy.

There are three types of hygrometers.

Metal Spring Hygrometers

This type of hygrometer is used in the majority of all humidors. They are less expensive but of limited accuracy.

Natural Hair Hygrometers

These hygrometers are much more accurate. Unfortunately, substantial maintenance work is required to maintain the accuracy of these humidors.

Synthetic Hair Hygrometers

These hygrometers are approximately as accurate as natural hair hygrometers; however, they do not require any maintenance on the part of the user.

How to Calibrate a Hygrometer

After purchasing a hygrometer, or a humidor with one built-in, some simple preparatory steps need to be carried out before using the instrument. There are two methods of calibration.

Hygrometer Calibration: Method 1

The recommended and most accurate calibration method is to place the hygrometer and a salt solution together in a small plastic box. You can make the salt solution by adding a few drops of water to a small cup of salt. The salt should not dissolve, only be damp.

Place the hygrometer and the salt solution in a well-sealed plastic box and wait. After about 8 hours, the humidity within the box should have reached 75% precisely. Adjust the hygrometer to this value.

Hygrometer Calibration: Method 2

A slightly easier but potentially less accurate way of calibrating your humidor is to wrap the humidor in a thoroughly wet cloth. After about an hour, adjust the hygrometer to 96%.

How to Prepare Your Humidor

Filling the Humidifier

Place the humidifier on a plate and moisten it with Propylene Glycol solution. Leave the humidifier in the solution for as long as it takes to absorb a sufficient amount of liquid (usually 5 minutes). Dry the humidifier with a cloth and place it in the humidor.

Moistening the Humidor

It is a common misconception that the walls of a humidor should be wiped with a damp cloth. Here at Havana House, we do not use this method and do not recommend it to anyone.

The best way to prepare a humidor is to leave a glass filled with distilled water in a humidor for three days with the lid closed. The water will slowly evaporate, and the inner walls of the humidor should have absorbed a sufficient amount of moisture.

After this, place your humidifier inside the humidor, again with the lid closed, and allow the humidity to stabilise. This will also take around 2-3 days. After this process is completed, your humidor is ready to keep your cigars!

How to Store Cigars in a Humidor

There are many different variables to take into account when storing cigars. The most common question is ‘do humidors need fresh air?’ The answer is yes.

The atmosphere inside a cigar box can become stale if left, as air does not easily escape and enter a good humidor. At least once every two weeks, humidors should be refreshed with new air.

What is the Best Temperature for Cigar Storage?

A temperature of around 18-21 degrees Celsius is considered ideal for storing cigars. At lower temperatures, the desired ageing process of the cigars is impaired.

Therefore, chilly wine cellars are only suitable for cigar storage to a limited extent. High temperatures are even worse. Over 24 degrees Celsius, is the best heat for tobacco worm infestation and cigar rotting. For this reason, humidors should not be exposed directly to sunlight. In addition, sunlight can bleach the hue out of humidors, which you may want to avoid if using it for ornamental purposes.

How Long Should Cigars Be Kept in a Humidor?

It is often said that time is a cigar’s best friend. Generally speaking, cigars can be stored for an unlimited period of time as long as the humidity remains around 65-70% and a regular supply of fresh air is maintained.

High-quality cigars, notably Cuban cigars but also some premium non-Cuban brands, develop a special flavour after many years of storage. In the UK, there is a long tradition of storing cigars for the optimum unfurling of the flavours.

In fact, before premium cigars are shipped to tobacconists, they are usually ripened for about six months. Due to increased demand, the ripening period has become increasingly shorter over the past few years.

Therefore we would urge you to store your cigars for an additional 3-6 months before they are smoked. In the end, it is up to the preference of the smoker as to how long to store his cigars for. It is a good idea to purchase a bundle of 50 cigars and smoke once a week to observe the changes in flavour and smoothness.

How to Marry Cigars

Cigars absorb aromas from their environment. Over time, aromas and taste infuse. If you were to store your cigars in a bread bin, they would have a grainy, wheat-like taste.

The same goes if you were to store your cigars in a meat locker or a laundry basket (none of which are advised). One of our customers reportedly stores his cigars in his garden shed as he adores the aroma of freshly cut grass and woodiness.

When storing cigars in a humidor, it is important to remember that cigars not only absorb flavour from the wood lining but from the cigars around them. Dividers are used in humidors to minimize this phenomenon. Some aficionados, however, appreciate the mixture of flavours and intentionally store different lines of cigars together for several months. This is called cigar marriage.

Rotating Cigars in a Humidor

A common issue with humidors is uneven and varying humidity levels. This problem is especially common in humidors that are filled close to maximum capacity. The solution to this issue is to rotate cigars between humidors. Cigars that are stored for long periods of time may be rotated every 1-3 months.
