Store Cuban cigars at 65% relative humidity and between 16 and 18°C, and check the number with a hygrometer you have calibrated, not one you trust. That is the whole answer. Habanos S.A., which makes them, gives a range of 65 to 70%; I keep my own boxes at the bottom of it and have for years, and every experienced Cuban smoker I know has drifted the same way. The rest of this article is why, and how to hold that number in a Swedish flat in January, which is harder than holding it in Havana.

The 70/70 rule is an American rule

You will read “70% humidity, 70°F” everywhere. It comes from the United States, where the cigars are mostly Dominican, Nicaraguan and Honduran, rolled a little looser and wrapped in leaf that shrugs off moisture. On those cigars 70% is fine. On a Cuban it is a mistake you can taste.

A Habano is rolled tighter than most non-Cubans; the torcedores in the Havana factories pack the filler firmly, and the wrapper is thinner and more delicate than a Connecticut or a Nicaraguan leaf. At 70% and above, that firm bunch takes on water and swells. The draw closes up. The burn goes crooked because wet tobacco burns unevenly. The smoke tastes flat and bitter, with a wet-hay note at the back that people blame on the cigar when it is the humidor. And the thin wrapper, swollen, cracks the moment you cut it or the moment you light it and the leaf starts to shrink.

Drop the same cigar to 65% for three weeks and it is a different cigar: the draw opens, the burn line straightens, the flavours separate. This is not a secret; it is why Habanos itself gives a range that starts at 65 rather than a single figure of 70, and why many Cuban smokers keep their humidors at 62 to 65 in practice.

What actually happens at each number

Relative humidity	What the cigar does
Below 58%	Dries out. Wrapper gets brittle, oils fade, the smoke turns hot and thin. Recoverable if caught early, slowly.
60–62%	Where many veterans keep Cubans they are smoking now. Fast burn, open draw, very clean flavour. Slightly less forgiving of a cold room.
63–66%	The sweet spot for Cubans. Open draw, straight burn, full flavour, safe margin against mould in both directions.
67–70%	Habanos’ upper limit. Fine for storage, but on a tight Cuban the draw tightens and the burn wanders. Let it sit a week below this before smoking.
Above 72%	Mould risk climbs, wrappers split on cutting, cigars taste soggy and harsh. Dry it down gently.

The numbers are the reading inside the box or drawer, not the reading on the hygrometer glued to the lid, which is often two or three points off and sometimes ten. Calibrate it once with the salt test (a capful of table salt, a few drops of water, sealed in a bag with the hygrometer for eight hours; it should read 75%) and you will know your offset for good.

Temperature matters more than people think

Habanos gives 16 to 18°C, and the reason is not flavour, it is beetles. Every cigar carries tobacco-beetle eggs from the field; they stay dormant in a cool box and hatch reliably from about 23°C, with almost none hatching below 21°C (the full account is in our beetle guide). A humidor at 70% and 24°C in a warm flat is an incubator. Habanos’ own advice is blunt: never let the temperature in your humidor exceed 18°C, and if you find a hatch, freeze the box for a few days. I keep mine in the coolest room in the flat, away from the radiator and the window, which in Malmö means the hallway, and I have never had a beetle in Europe. In Havana I had them twice, both times in summer, both times in a cabinet that had crept above 25°C.

Cooler storage also slows ageing, which for a Cuban you intend to keep five years is what you want; and it lowers the amount of water the air can hold, which is why the same humidifier that holds 65% at 18°C reads 70% at 24°C. Fix the temperature first and the humidity gets easier.

Holding 65% in northern Europe

This is the part the American guides never cover. From November to March, a Swedish or German flat with the heating on sits at 20 to 30% relative humidity — desert air. A wooden humidor in that room is losing water through its walls every hour, and a single sponge humidifier cannot keep up. My rules, learned the hard way:

Use two-way packs, at 65. Boveda’s 65% pack (it also makes 69 and 72; Boveda itself describes the 65 as “for those who prefer a drier cigar profile and/or easier burn; good for long-term ageing”) both gives and takes moisture, so it corrects overshoot as well as undershoot. One 60-gram pack per 25 cigars is the usual rule (Boveda 65%, size 60, $8.80 on Amazon.com on 21 October 2026); in winter I run double, and I still replace them more often than the packet promises. A crystal-gel or foam humidifier can only add water, which is exactly the wrong tool when the season flips and the flat turns humid in July.

Season the humidor properly before it sees a cigar. A new wooden box wants two weeks with a bowl of distilled water inside and no cigars, until the lid reads 65 on its own. Boveda’s 84% seasoning pack ($8.80) does the same job without the risk of spilling water on the cedar. Skip this and the cedar drinks the moisture out of your first box of Robustos.

Keep the boxes closed inside the humidor. A dress box of 25 with its lid on is its own micro-climate; the cedar of the box plus the cedar of the humidor is two layers of buffer. Loose singles in a tray swing with every opening of the lid.

Open it less. Every time the lid comes up in January you swap 65% air for 25% air. Take out what you will smoke this week, close it, leave it.

Check with a probe, not the lid gauge. A digital hygrometer with a probe on a lead, pushed into the drawer where the cigars are, reads the air the cigars are in. It is the single most useful thing in my humidor and it cost less than a Cohiba.

If you’d rather not run a lead into the box, a small digital hygrometer that sits in the drawer among the cigars does the same job: the Govee H5075 ($12.99, 4.5 stars from more than 48,000 ratings) shows the reading on your phone, so the lid stays shut. Calibrate it with the salt test before you trust it. For the humidor itself, see the best cigar humidors of 2026.

Bringing a dry cigar back

If you inherit a box that has sat in a cupboard, or your humidor ran dry over a holiday, do not put the cigars straight into 70%. Habanos’ warning is worth repeating: re-humidify gently in stages, or the wrappers burst as the leaves swell. Start them at around 60% for two weeks, then 65% for another two, in a closed box with a pack. A cigar dried to 50% takes a month to come back; a cigar that has been dry for a year may never recover its oils, and you will know from the first inch.

Travel, briefly

A cigar in a jacket pocket in a Swedish winter dries measurably in a day. For a weekend away, a small travel case with one 65% pack holds a handful of cigars at the number they left home at; without a pack, a sealed tube is better than a leather case, and a leather case is better than a pocket. I carry three to five in a case with an 8-gram pack and never more, because anything more than a week’s cigars should stay in the humidor.

A sealed hard case such as the Cigar Caddy ($27.99) holds a pack and survives a suitcase. Our travel case guide covers the other kinds.

Questions

What humidity should Cuban cigars be stored at?

Between 65 and 70% relative humidity according to Habanos S.A., and at the low end of that, 63 to 66%, in practice. Cuban cigars are rolled tighter with thinner wrappers than most non-Cubans, and above 68% the draw tightens, the burn wanders and the wrapper splits on cutting.

Is 65% or 69% Boveda better for Cuban cigars?

65% for Cubans. Boveda describes its 65 as for a drier profile and easier burn and good for long-term ageing, which is exactly what a Habano wants. 69 is fine for storage but let a Cuban sit at 65 for a week before smoking it.

What temperature should a humidor be for Cuban cigars?

16 to 18°C, and never above 18°C for long, because tobacco-beetle eggs present in every cigar hatch from about 23°C. Cooler storage also slows ageing and makes humidity easier to hold.

How do I keep my humidor at 65% in winter?

Two-way humidity packs at 65 (double the count in winter), a properly seasoned box, cigars kept in their closed dress boxes inside the humidor, the lid opened as rarely as possible, and a probe hygrometer in the drawer rather than the gauge in the lid.

My Cuban cigars are dry — can I save them?

Usually, if it has been weeks rather than years. Re-humidify in stages: two weeks at around 60%, then two at 65%, in a closed box with a pack. Putting a dry cigar straight into 70% swells the leaf too fast and splits the wrapper.
