How to Season Your Humidor: A Comprehensive Guide

What is the key to a properly seasoned humidor? The answer is simple: moisture. Humidors need to be kept at the right humidity level for optimal performance. If this requirement is not met, then your cigars will dry out and lose their flavor. Seasoning a humidor means adding moisture to it so that you can maintain the correct humidity levels all year long. In this article, we take an in-depth look at seasoning your humidor, including what you need and how to do it correctly!

I have collected many different cigars from all over the world that I keep in my humidor. My collection has grown to be quite large, and it is a hobby that has become popular throughout the globe!

Here is the shortest and the most common instruction. More information inside the article.

Short Instructions: Seasoning Humidor

  • Prepare humidor. Remove everything from the humidor and clean it
  • Calibrate analog hygrometer or use only digital. Add analog hygrometer inside and digital one outside of the humidor
  • Add propylene glycol solution for humidifier
  • Find a cool place for the humidor. Wait for 65-85 degrees Fahrenheit, while the humidity level should be around 70%.
  • Done
  • Optionally: check periodically

Why is it important to season a new humidor?

Because we should make perfect conditions for cigars BEFORE putting them in the humidor. Cigars are a luxury to most, but now, they can be accessed with just one click, thanks to the online world. However, this is not without its own drawbacks, as novice smokers don’t always know what happens if their cigars sit out in the open for too long.

How to Season Your Humidor: A Comprehensive Guide

In humidors that maintain proper humidity before smoking and prevent premature drying of these leaves that will eventually turn into your cigar – you’ll have both an expertly crafted smoke and peace of mind knowing it’s well-deserved!

A beginner smoker might think there isn’t much risk involved when purchasing online – it doesn’t matter where from, right? Wrong! The problem lies within how quickly fresh tobacco dries up after being left outside or exposed to sunlight;

There are few things worse than smoking a stale cigar, other than having one that’s molded. It can happen when humidors aren’t properly seasoned before use. This guide will show you how to season a humidor correctly and list all the things you’ll need with you before getting started, so your cigars stay fresh!

There is lots of misinformation on the internet about this topic which incorrectly teaches people to do it differently from what they really should; these steps below will help clear up any confusion for anyone who wants their cigars in tip-top shape no matter where they store them or how often they smoke them.

How Long Does It Take Season a Humidor?

The process of seasoning a humidor can take anywhere from one day to four weeks. The longer you season it, the better your results will be! Once you’ve seasoned your humidor for at least three days, it should hold humidity levels without any more treatment needed – meaning that after this time, you’ll only need to vacuum and wipe down its interior on occasion (every few months).

If you’re really into cigars or want them in top shape all year round, then I recommend leaving the lid open after every use so that air circulates inside; this easily lets moisture out while allowing new air in and helps keep your sticks fresh no matter what their location is.

  • Find the boveda packs and select a pack that best corresponds to your humidor size.
  • Remove some of the foam or felt inside from the bottom tray and place it on top of this piece to create an enclosed space for the boveda pack. This will ensure that there is no airflow to ruin our work! Place one side at least two inches away from any walls to get good contact with all surfaces.
  • Place the selected boveda pack into its designated section you created earlier until they are tightly pressed against each other; do not stack them as per their instructions because stacking may result in uneven moisture distribution throughout your humidor.
  • Put the lid on your humidor and close it tightly; this will ensure that no air can escape from inside the container.
  • Let sit for at least 2 weeks before opening to check how things are going!
  • After through away seasoning packs and put preferred boveda packs (69%, 72%, or 75%). And the rule is the same as from the table above.
  • And you’re ready to put cigars in the humidor!

*Tips: We encourage using a hygrometer in order to monitor these changes during season time.*

Universal Method For Seasoning Humidor

I found the best way to seasoning humidors for years of smoking cigars,s and I’m sure this method is easy and safe for humidors and cigars. This is the fastest way to season a humidor.

What you Need to Get Started

A humidor needs to be seasoned once before use so that it will maintain a steady humidity level. There are several objects you’ll need to have on hand to string the season successfully:

  • Humidor: You will need a humidor to season it. But the reason I’m telling you this is because there are different types of cases that people use when they’re seasoning their humidors by the book. In plain terms, don’t try and do this with one that’s already been seasoned before! Attempting something like this could lead to irreversible damage to your cigars or even make them stale sooner than expected, so always start fresh if you want an accurate result. Be sure while searching for a new case. The lid forms an airtight seal not to let any moisture out either, which can ruin your cigar collection too soon; remember then how big of size should be ordered for what amount of cigars anticipated inside?
  • Humidifier: For most humidors, the humidifier is a built-in part of the unit. This means that you don’t need to buy one separately. The important thing is to make sure it’s not too big or too small for the space you have available – usually in the lid area of your case.
  • Propylene Glycol: A humidor needs to have humidity regulated to keep mold from growing. Propylene glycol is a popular additive that can be purchased at your local hardware store. You will need a plastic bottle, distilled water, and the solution itself; depending on the concentration of the propylene glycol or whether you use undiluted, it will depend on how much distilled water you add.
  • Distilled Water: Distilled water does not contain the minerals that could lead to rotting or mold in your humidor. It is available at any grocery store, so buy some before beginning the process. You do not have to chill it; make sure it stays at room temperature throughout the process.
  • Hygrometer: A hygrometer is an instrument that’s crucial to the process of seasoning a humidor. You’ll need one to monitor the humidity level inside your case, as it will be different from time to time depending on how often you open up its lid for use.
  • Small Glass Cup: One of the essential steps in seasoning a humidor is to fill your glass cup. For large boxes, use larger glasses; for smaller cases, cups measuring up to 12 ounces will be sufficient.

Pro Tip: You can use the sponge as an alternative if you cannot acquire the propylene glycol (but I recommend against it unless it’s necessary). It will be more difficult to maintain a humidity level of around 70 degrees and take longer to dry out during the seasoning process.

Step 1: Prepare Humidor

All of the contents, including racks and dividers that come with your humidor, should be removed.

How to Season Your Humidor: A Comprehensive Guide

Please note, if you are seasoning a used case, then all cigars must be transferred elsewhere!

  • Remove everything from inside of the box or move it to another container for safekeeping during this process. Be sure not to leave any cigar stubs in the humidor because they could combust, leading to a fire.
  • Take out all of your dividers and racks that come with the box if you happen to have them for added storage; this is also an opportunity to clean and polish these pieces as well while inside.

Find a clean cloth and dry out the humidor inside to remove any dust or debris accumulated.

Pro Tip: Do not wipe down the humidor with a sponge. Doing so could result in you replacing your entire case and creating an environment conducive to mold growth. Additionally, coating the wood can make it so that when a humidor is seasoned, the propylene glycol won't stick, and the warping of the wood will become permanent. In short, stay away from any distilled water to coat your humidor.

Now you are ready for step two!

Step 2: Calibrate Humidifier and Hygrometer

While filling your humidifier with propylene glycol solution, ensure you’re using distilled water if necessary. For a glass cup measuring approximately 1/4 to 1/2 full of the same mixture, mix in distilled water until it’s about 3/4 full.

If you would like a smaller glass jar, feel free to use one. More water used may lead to quicker seasoning times, but this depends on your humidor’s size. Following this, place the humidifier at the bottom of your humidor and add a small glass.

When you’re finished, put the hygrometer in and close the lid. Place a flat, thin piece of paper that preferably fits on top of your dollar bill (or some other type) inside the humidor and make sure it rests snugly between the lid-membrane as well as at its opening. If it doesn’t move when pulled slightly, then you should have created an airtight seal around which no air may come in or out.

Pro Tip: If you want, you can use a clean sponge and soak it in distilled water. It should be brand new and has never been used on any surfaces before. Place the sponge inside your humidor and put it on a small porcelain plate for food safety reasons.

Step 3: Find The Cool Place

Humidors are best kept in a cool, dry place. The ideal temperature is between 65-85 degrees Fahrenheit, while the humidity level should be around 70%.

Once you have your humidor where it needs to go, we recommend placing an analog hygrometer inside with a digital one just outside of the box and monitor their readings for about 24 hours before using any additional steps.

If, at that point, the reading on both gauges is within five percent or so, then congratulations! You’ve successfully seasoned your first humidor! If not, continue following the instructions below.

Remember, there’s a glass filled with water inside, so be just as careful when picking it up and moving. If you spill a little water underneath the glass, quickly wipe it up with a clean and dry cloth, changing glasses if needed.

Step 4: Check Periodically

Keep in mind that your humidor requires a little maintenance and care.

Pro Tip: You should check the humidity level at least every week, but you can do so more often if you wish to maintain consistency with it.

Humidity levels of 65-73% are typically safe, but you should aim for lower levels if you’re in a very humid environment. If the humidity is too high, your cigars won’t get a chance to absorb moisture internally.

Step 5: Adding Cigars

Once your humidor has the appropriate humidity, remove distilled water or a wet sponge. There should be no trace of dampness anywhere on the inside.

To season a humidor, place the humidifier in its desired position and get your cigars ready. For those that you plan on smoking very soon, you don’t have to remove the cellophane. Aging should always be done with no cellophane, so if there’s anything you want to keep for a while, remove it before seasoning or aging your humidor.

Once you’ve done this, close the lid and let your cigars rest for a few days or up to about two weeks, if possible, before smoking them. If anything needs adjusting along the way, feel free to check back with us!

That’s it! If you take your time and follow these steps, then your humidor will be ready for smoking within no time at all. Patience is key here, so make sure to avoid rushing any of the processes listed as this can lead to damaging effects on the humidor.

Humidors are sensitive objects and season them correctly to ensure that your smokes taste great when smoking.

Congratulations on mastering the art of how to season your humidor! With these steps, you’re now prepared with everything you need to maintain a healthy, functioning box that will keep your favorite cigars fresh. Whether it’s time for a new one or just some maintenance to an old friend, this comprehensive guide should help get those smokes going sooner than ever before.

The Wipe Down Method

This is the most commonly used method for seasoning a humidor. There are several steps to this process:

How to Season Your Humidor: A Comprehensive Guide

  1. Step One: Wipe down your entire humidor with distilled water (be sure not to get any inside) and then wipe it off again until there’s no trace of dampness anywhere on the inside.
  2. Step Two: Place paper towels or some other type of material in between the lid-membrane as well as at its opening, creating an airtight seal around which no air may come in or out. Make sure that they rest snugly against one another– if you can’t easily make them touch without any gaps, then try something else like plastic wrap instead. The idea here is to create a barrier so that humidity can’t escape.
  3. Step Three: Fill the humidifier with distilled water and place it in its desired position, just outside of your box, so that no moisture gets inside for now.
  4. Step Four: Place an analog hygrometer inside to monitor readings while there’s also a digital one placed right outside of the box at all times as well. Allow these gauges to read their respective numbers for around 24 hours before going any further; if they’re both within five percent or so, then congratulations! Your first attempt was successful– you’ve successfully seasoned your first humidor! If not, continue following the instructions below.

What To Do Next?

You should check on your humidity levels every week but may do more often depending on how humid your environment is.

If the humidity gets too high, it’s not good for cigars as they won’t get a chance to absorb moisture internally and dry out easily. If this happens, remove some of the distilled water from the humidifier until you reach an appropriate level– 65-73% are typically safe ranges but may vary on what type of climate you’re in.

How to make propylene glycol solution for cigar humidifiers?

Firstly, check instructions for your humidifier: some models use only distilled water! For others, propylene glycol solution is 50% of distilled water + 50% propylene glycol. That’s it!

Seasoning humidor – shot glass method

This is the other popular method of seasoning a humidor. Get at least three shot glasses – one for distilled water, one for propylene glycol solution, and one to collect the excess liquid after each application. Once you have those ingredients ready, follow these steps:

Pro Tip: we don’t recommend using this method because it is hard and not universal.

  1. Place your case on its back with the lid open so that all of it can be reached inside easily (you will need access). Clean off any dust or debris from the interior; start by wiping down every surface thoroughly with a damp sponge, then dry it off completely using a paper towel before proceeding. When done, wipe down again, but this time uses an alcohol-free sanitizing wipe as well.
  2. To make sure you’ve cleaned everything sufficiently without leaving anything behind, like traces of moisture, wipe down the inside with a paper towel and then touch it to your fingertip. If there is moisture, continue wiping until dry; if not, you’re done!
  3. You will now need to fill your glass cup for this process to work well. Fill one of your shot glasses two-thirds full with distilled water (make sure it’s room temperature) and put that off to the side. Put another shot glass in front of you on the table, which should also be filled halfway up but only have propylene glycol solution present – no water necessary here because we want everything fully saturated without any risk of mold or premature rot happening before time has passed while curing out at room temperature.
  4. Now, take the last third of your shot glass and fill it all the way with propylene glycol solution – this will act as a sponge to absorb excess liquid.
  5. Now place one hand inside the case while holding on to the top so that air is not escaping from any gaps in between; if you’re using a humidor, make sure it’s completely sealed up before proceeding. With your other hand, take your snow-filled cup and slowly pour distilled water (from half) into the side of the interior where you had just cleaned off dust or debris, making sure there are no streaks present anywhere for an even distribution of moisture throughout.
  6. Then, use those same fingers touching down to feel around every surface with them until they become wet with distilled water. If there is a dry spot, it needs to be rubbed down again until wet for the surface area to fully cure off without any risk of mold or premature rot happening while being made ready for cigars and cigar accessories.
  7. This process may need to be repeated as many times as necessary (sometimes upwards of four) depending on how large your humidor is inside – always fill up from half rather than all the way up because you want this entire process done quickly so that no contaminants can get into your new box before time has passed at room temperature (which might happen if using full bottles).
  8. Once everything has been sufficiently dampened, take some time out and let things air-dry overnight; rub everything down with a clean paper towel to make sure there’s no excess liquid left behind.
  9. Once everything has dried, it should still be humid enough inside that you can leave the case open for 24 hours without worrying about any issues in terms of humidity (don’t take out anything from your new box during this time).

Next Steps: Implement the steps described above and monitor until desired levels are achieved.

  1. If too much moisture is present after 48hrs as judged by touching down on surfaces or feeling wetness when wiping them down, remove some dampened items before placing them back into the cabinet – do not saturate the interior again
  2. If needed, repeat the process if cigars become slightly tacky but dry upon light handling; discard all moistened sponges and paper towels.
  3. Use a clean, dry cloth to wipe down surfaces until they are dehydrated before placing cigars or accessories inside.
  4. Place items in the humidor from top to bottom so that air can flow better through it – this will also help you determine if your levels of relative humidity need adjustment (if too moist), then remove dampened items periodically during the first few weeks of use.

Now you know how to season your humidor. The next time you’re ready to light up, don’t forget all the things that went into preparing this essential piece of cigar-smoking equipment so it can do its job properly. Whether or not you need a new one, just some maintenance on an old friend, or want to make sure yours is always functioning at peak capacity, these steps will help keep those smokes going sooner than ever before!


Now that we’ve covered how to season a humidor, let’s answer some commonly asked questions:

How do I know if my cigar has been ruined by improper storage?

Cigars should have a light brown hue with no visible cracks or splits when stored correctly but will turn blackish after being exposed to certain substances like oil or chemicals with a strong, pungent odor.

What should I do if my cigars have started to mold?

Mold is often caused by crazy fluctuations in temperature and moisture levels-- but don't worry! There are a few things you can try before giving up on your box of smokes: Place them in the freezer for 72 hours (not longer than this, however) or bake them at low heat for around ten minutes per cigar.

How long does it take to season a humidor?

It will take about 30-60 days when following our instructions closely though the time may vary depending on the number of factors impacting humidity, such as location indoors/outdoors and how large your humidifier is. The time required might be shorter if there's less of a gap in between your humidity levels.

When I should season my humidor?

Humidors need to be seasoned after they are opened and before cigars are stored in them.
