Quick answer: Cigars do not expire, but they go bad without humidity. Left out, they dry within a day. In the original box they last a few days to two weeks; cellophane adds a day or two. In a humidor at 65 to 72 percent humidity they last for years. Mold, cracks or a musty smell mean the cigar is done.
Cigars don't have an expiration date stamped on the box, but they can absolutely go bad. Stored well, a cigar lasts for years and often improves with age. Stored poorly, it can start drying in a day, mold in weeks, or lose its flavor permanently. This guide covers how long cigars last, how to spot a bad one, how to rescue a dried stick, and how to store them so it never happens again.
Do Cigars Expire?
No. Cigars are tobacco, not food, and tobacco does not have a chemical shelf life the way meat or milk does. What cigars have is a storage requirement. Maintain the right humidity and temperature, and a cigar can sit in a humidor for decades and still smoke well. Skip the storage, and it starts losing flavor within a day.
- In a proper humidor (65 to 72 percent RH, around 70°F): indefinite shelf life. Some 10 or 20-year-old boxes taste better than the day they were rolled.
- In a sealed bag with a humidity pack: weeks in a zip bag; Boveda says at least six months in its own Humidor Bag.
- In the original box, no humidity pack: a few days to about two weeks, according to Boveda. A factory box is not airtight. Cellophane alone buys only a day or two over a bare cigar.
- In open air on a desk or shelf: Cigar Aficionado says cigars start to dry out within a day.
How Long Do Cigars Actually Last?
A healthy cigar's lifespan depends entirely on its environment. Here's a quick reference.
The single biggest variable is humidity. Temperature matters too, but humidity is what kills (or saves) most cigars. For the full storage breakdown, see our cigar storage guide and our humidor buying guide.
How Long Does a Box of Cigars Stay Fresh Without a Humidor?
Not long. A cigar box from the store is not airtight, so the cigars inside dry at roughly the speed of the room around them. Boveda puts it at a few days to about two weeks in the original box, and cellophane sleeves buy a day or two at most. Dry winter air or air conditioning shortens that, and a hot car or garage can ruin a box in an afternoon.
If you cannot get the box into a humidor, put the cigars in a zip bag or plastic container with a Boveda pack (69 percent is the company's pick for most cigar storage) and seal it. That holds them for weeks, and a Boveda Humidor Bag holds them for months. A gallon zip bag and a spare pack is the cheapest humidor there is, and worth keeping on hand for the day a box arrives before you have room for it.
How to Store Cigars Without a Humidor
No humidor yet? Any airtight container plus a two-way humidity pack does the job for a while. Three setups, from smallest to largest:
- Zip bag: a freezer-grade zip bag with a Boveda pack inside, pressed shut. The cheapest option, fine for a handful of cigars for a few weeks.
- Tupperdor: an airtight plastic food container with a humidity pack, which is what smokers call a tupperdor. Boveda's sizing rule is one Size 60 pack for every 25 cigars the container holds, or one Size 8 pack for every 5. Boveda suggests replacing packs about every three months, or sooner if one feels hard all the way through at room temperature.
- Coolerdor: a clean, new cooler with enough Size 60 or Size 320 packs for its capacity holds a box or more and keeps light out. Add a hygrometer so you can check the reading without opening the lid often.
Three things to avoid:
- The refrigerator. It is too cold and too dry for cigars, and a cold cigar risks condensation as it warms up.
- Mixing flavored cigars in. Infused cigars pass their aroma to plain ones, and Cigar Journal advises always storing them separately. Give them their own bag or container.
- Heat and sun. A windowsill, car, or garage undoes any container.

How Long It Takes to Smoke One
How long the cigar lasts in your hand depends mostly on size and shape (vitola). Steady-paced numbers:
| Vitola |
Dimensions |
Smoke time |
| Petit corona |
4.5 x 42 |
30 to 45 min |
| Robusto |
5 x 50 |
45 to 60 min |
| Corona |
5.5 x 42 |
45 to 60 min |
| Toro |
6 x 50 |
60 to 90 min |
| Churchill |
7 x 47 |
90 to 120 min |
| Lonsdale |
6.5 x 42 |
60 to 75 min |
| Torpedo |
6 x 52 |
60 to 90 min |
| Lancero |
7.5 x 38 |
60 to 90 min |
These times assume one puff every 30 to 60 seconds. Smoke faster and the cigar burns hot and tastes harsh. Smoke slower and it may go out, requiring relights. For the full vitola breakdown, see the cigar sizes guide.
4 Signs Your Cigar Has Gone Bad
Before you light up, run a quick four-point inspection.
1. The Wrapper
A healthy wrapper is smooth, slightly oily, and fully intact. Bad signs:
- Cracks or flaking mean the cigar is too dry. Sometimes recoverable, often not.
- Unraveling at the head or foot means the wrapper has separated from the binder, usually from a humidity swing.
- Visible mold anywhere on the wrapper is a hard rule: discard the cigar.
2. The Smell
A fresh cigar smells like sweet tobacco, cedar, hay, or barnyard. Bad smells include:
- Ammonia (sharp, eye-watering): the cigar was stored too damp and is fermenting.
- Musty or wet-cardboard: mold or mildew, even if you can't see it yet.
- Chemical or solvent: rare, but a hard pass if you smell it.
3. The Feel
Pinch the cigar gently between thumb and forefinger near the middle:
- Firm with slight give, like fresh bread. Healthy.
- Hard and crunchy, no give at all. Dried out.
- Soft and spongy, finger leaves an impression. Over-humidified, possible mold inside.
4. The Foot and Head
Examine the cut foot (where you light it) and the head (where you cut it):
- A fine, dust-like white film that brushes off easily is plume (also called bloom). It's a harmless byproduct of aging tobacco oils crystallizing on the surface. Plume is a good sign.
- Fuzzy, blue-green, or yellow growth is mold. It does not brush off. The cigar is done.
Can You Smoke a 20-Year-Old Cigar?
Yes, if it was stored at steady humidity the whole time. Age alone does not ruin a cigar; bad storage does. Expect an old cigar to taste milder and rounder than it did new, because the bold flavors fade with time. Plenty of smokers think most cigars peak somewhere in the first five to ten years, which is why Boveda notes some experts cap their aging advice at five years. Before you light a 20, 30 or 40-year-old cigar, give it the same checks as any other: no fuzzy mold, no cracks, no musty or ammonia smell, and a firm feel with a little give. If it passes, it is worth smoking just to taste the difference.
Plume vs Mold: The Critical Difference
This is the single most-asked question about old cigars, so it deserves its own section.
| Plume |
Mold |
| Fine, white, powdery, looks like dust or frost |
Fuzzy, raised, blue-green, gray, or yellow |
| Brushes or wipes off cleanly |
Doesn't brush off; embedded in the wrapper |
| No smell |
Musty, mildew, or sour smell |
| Indicates good aging |
Indicates the cigar is contaminated |
| Fine to smoke |
Throw it out and check the rest of the box |
If you find mold on one cigar in a humidor, inspect every other cigar carefully and the humidor itself. Mold spores spread.
How to Revive a Dried-Out Cigar
If a cigar has dried out but is still physically intact (no cracks, no broken wrapper), you can rehydrate it. Slowly. Rushing kills the wrapper.
- Place the cigar in a sealed container with a 65 percent Boveda pack or similar humidification device. A tupperware container works fine for this.
- Wait two to four weeks. Resist the urge to check or open the container daily. The cigar needs to absorb humidity gradually so the wrapper doesn't crack.
- Test by feel. After two weeks, give the cigar a gentle squeeze. If it has the firm-with-give feel, it's ready. If still dry, give it another week.
- Don't expect full flavor recovery. A revived cigar smokes again, but rarely tastes as good as it did fresh. Severe dry-out is permanent damage you can't reverse.
Never try to rehumidify by spraying water, microwaving, or putting the cigar near a damp paper towel. Fast humidification breaks the wrapper and ruins the construction.
How to Store Cigars So They Don't Go Bad
The single most important thing you can do for your cigars is to control humidity. Everything else is secondary.
- Get a real humidor with a tight seal and a working hygrometer. Wood-lined (preferably Spanish cedar) is the standard. Avoid pure glass humidors, they look nice but rarely hold humidity well.
- Target 65 to 70 percent relative humidity. Boveda recommends 69 percent for most cigar storage; some smokers prefer 62 to 65 percent for slightly drier, more focused flavor. Either is fine. Avoid going above 72 percent, which invites mold.
- Maintain a stable temperature around 65 to 70°F. Avoid attics, garages, or anywhere with big day-night swings.
- Use a calibrated hygrometer. Cheap analog hygrometers read incorrectly out of the box. A digital model or a calibrated one is worth the upgrade.
- Use Boveda packs or a similar two-way humidification system for set-and-forget control. Old-school sponge humidifiers work but require regular maintenance.
- Keep cigars in their cellophane if they came that way. The cello slows humidity changes between cigars and protects the wrapper.
- Don't crowd the humidor. Cigars need a little room around them for air circulation. Stack rotations every couple of months also help.
- Stay out of direct sunlight. UV degrades the wrapper oils and bleaches the leaf.

Frequently Asked Questions
Do cigars expire?
No, not in the food sense. Cigars are dried tobacco and don't spoil chemically. But they do dry out, lose flavor, or develop mold without proper humidity control. Stored correctly, they last indefinitely.
How long do cigars last without a humidor?
They start drying within a day in open air. In the original box, a few days to about two weeks; cellophane adds only a day or two. In a sealed zip bag with a Boveda pack, several weeks. For anything longer, you need a real humidor or a Boveda Humidor Bag.
How long does it take to smoke a cigar?
A robusto (5 x 50) takes 45 to 60 minutes. A churchill (7 x 47) takes 90 to 120 minutes. A corona (5.5 x 42) takes 45 to 60 minutes. Smoke faster than that and the cigar burns hot.
How long does an opened box of cigars last?
A few days to about two weeks without humidity control, because cigar boxes are not airtight. Put the box in a humidor, or the cigars in a zip bag with a Boveda pack, and they keep for weeks to months.
How long do cigars last in cellophane?
Only a day or two longer than bare cigars. Cellophane slows moisture loss but does not stop it, so cellophane-wrapped cigars still need a humidor or a sealed bag with a humidity pack.
Can old cigars make you sick?
A dry or stale cigar will just taste bad. A moldy cigar should never be smoked, and neither should one that smells like ammonia or chemicals.
Do cigars get better with age?
Many do. Premium handmade cigars often improve over 1 to 5 years of proper storage as the tobaccos meld and harshness fades. Some, like Padrons or Davidoffs, are released ready-to-smoke and don't gain much from aging. Cheaper machine-made cigars don't age; they just slowly lose freshness.
What does cigar plume look like?
A fine, white, powdery dust on the wrapper, similar to frost on a grape. It brushes off cleanly. Plume is a sign of good aging, not a defect.
What is the difference between plume and mold?
Plume is white, powdery, brushes off, has no smell. Mold is fuzzy, often blue-green or gray, does not brush off, and smells musty. Plume is fine to smoke. Mold is not.
How do you revive a dried-out cigar?
Place it in a sealed container with a 65 percent Boveda pack and wait 2 to 4 weeks. Do not rush. Quick rehydration cracks the wrapper.
How do you store cigars without a humidor?
Seal them in an airtight container with a two-way humidity pack: a zip bag for a few cigars, or a plastic food container (a tupperdor) with one Boveda Size 60 pack per 25 cigars it holds. That keeps them for weeks; a Boveda Humidor Bag holds them for months. Keep flavored cigars in a separate container.
Can you store cigars in the refrigerator?
No. A refrigerator is too cold and too dry for cigars, and a cold cigar risks condensation on the wrapper as it warms up. Use a sealed container with a humidity pack at room temperature instead.
What temperature is best for storing cigars?
65 to 70°F (18 to 21°C) is the standard target. Cool basements, climate-controlled rooms, or wineadors work well. Avoid attics, garages, and anywhere with big temperature swings.
