Care

Time is the first thing you give it

A cigar that has just arrived is not the cigar it will be in three months. Travel and a change of climate leave it unsettled. The first few weeks in a stable box are it coming back to itself. After that the convention is a season. A cigar held at steady humidity that long is a different thing to one out of a bag last Tuesday.

These are conventions, not laws. The app holds them because “ready” has to mean the same thing on every cigar. If your own view is longer, set an aging target.

Rest counts from the day a cigar entered your humidor, not the day it was rolled. That is the one date you can know. A record that guesses at the other is one to stop trusting.

Pick a number, then hold it

Somewhere between 65 and 70 percent is where the argument lives. It is a preference, not a fact. Seventy is traditional. Plenty of keepers hold sixty-five and are happier for it. The second half is not in doubt: a steady 65% beats a 70% that swings ten points. Cedar and tobacco move with the air around them, and it is the movement that splits wrappers.

When a number is off, the cause is worth more than the correction. Nearly every humidor that will not hold humidity has a sealing problem being treated as a water problem. More water buys a bigger bill and the same reading. Check the seal first.

Every decision inherits the hygrometer’s error

A reading you have never checked is a guess with a decimal point. Digital units drift. Cheap analogue coils drift faster. Two hygrometers in one box disagreeing by six points is normal, and it is why the salt test exists.

Saturated salt in a sealed space holds a known 75% relative humidity at room temperature. You are not calibrating against another instrument. You are calibrating against physics. Half-fill a bottle cap with table salt. Add distilled water a few drops at a time until it is damp slush, not a solution. Seal it in a bag with the hygrometer, the two not touching. Leave it at steady room temperature for at least eight hours. An analogue dial wants a day. Read it through the bag. Seventy-five is correct. Seventy-one means it reads four points low.

Digital units with a calibration button reset to 75% on cue. Analogue dials have a screw on the back. If yours has neither, write the offset on the case and apply it every time. Test a decent digital unit twice a year. A cheap coil, quarterly.

Seasoning, and the seal

A new humidor is kiln-dried Spanish cedar, and dry wood is thirsty. Fill it before it is seasoned and it pulls moisture out of the cigars instead of holding it around them. Cracked wrappers, and a box stuck at 55%. Season it first.

Wipe the interior with a cloth barely damp with distilled water. Damp, not wet: standing water swells cedar and invites mould. Stand a shallow dish of distilled water inside on a coaster, close the lid, and refill it as it empties. Most desktop humidors take a week or two. The tidier route is 84% seasoning packs and no dish at all. Slower, but impossible to overshoot and nothing to spill. Either way the finish line is a reading, not a date. Stop when the hygrometer holds your target for two days on its own.

Distilled water is not fussiness. Tap water leaves scale on cedar and clogs gel and foam humidifiers. Its chlorine soaks into wood your cigars rest against for years. Spring and filtered water carry minerals too. Distilled is the only one with nothing in it.

Test the seal twice a year, and any time humidity drifts down for no reason you can name. Close the lid on a banknote so half stands proud, then pull. You want clear drag, at several points along the front and both sides. The middle is where a lid grips best, so testing only there proves nothing. One corner that releases easily tells you where the fault is. A fail is certain; a pass is only probable. A box that has run dry for months often fails because the cedar shrank, and seasoning brings the fit back.

One system, not two

There are two families and they do not co-operate. Two-way packs absorb and release until the salt solution inside is spent. Crystal, gel and foam units give up water and need refilling. Run both in one box and neither holds a stable number. Each is busy correcting the other.

A pack that has gone hard is not thirsty. It is finished. A working one is soft, like a gel pillow. Sizing runs about one 60 gram pack per twenty-five cigars, and an under-packed box swings with every opening. Replace them all at the same humidity, or a 65% pack and a 69% pack will spend their lives fighting. Take the old ones out, because a spent pack still drinks from the new ones. Expect two to four months. A tight seal and a full box push towards four; a leaky lid or a dry winter flat pull it down to six weeks.

Refillable units are the opposite discipline. Take the unit out before you open it, so a spill lands on the worktop and not on cedar. Fill slowly with distilled water, or the 50/50 propylene glycol solution it was built for. Glycol caps out near 70% and discourages mould, at the cost of clogging foam over time. Stop while the medium is still absorbing and wipe the outside dry. Judge the result the next day, not the next hour. A refill always overshoots briefly.

Temperature, and the beetle

Humidity decides how a collection ages. Temperature decides whether tobacco beetles hatch in it. The eggs are already in the leaf, and they wake as the box warms. That is what the traditional 21°C target is for. Risk climbs above roughly 24°C, and the classic case is a humidor that spent July on a sunny shelf.

Look for pinholes about a millimetre across along the wrappers and at the feet, and fine dust at the bottom of the box. Holes plus dust means beetles, not damage in transit. Seal the affected cigars and freeze them at around −18°C for three to four days. Then the fridge for a day. Then room temperature before you open the bag. The staged warm-up is the part people skip, and the part that keeps wrappers from cracking. Empty the humidor, vacuum it, wipe it down, and check every other cigar before it goes back. Freezing the holed ones and leaving the rest is how the problem returns in a month.

Mould is the other visitor, and the hobby disagrees with itself here. “Plume” is meant to be a crystalline bloom that brushes off harmlessly. Plenty of experts say plume does not exist and anything on a wrapper is mould. The test is texture and smell. Crystalline, brushes off, no stain, no musty smell: cosmetic at worst. Fuzzy, raised, musty or leaving a mark: mould. When you cannot tell, treat it as mould. Discard what is affected rather than wiping it and putting it back. Drop the humidity a few points, improve air movement, and look again in a week.

The seasons move the ordinary numbers. A dry winter flat empties a humidifier faster than a humid summer ever will, which is why pack life is a range and not a date. Rotation belongs to the same rhythm. Humidity is not even inside a box, and whatever sits nearest the humidification runs wetter than the far corner. Move the bottom layer up and the top down every couple of months, turning each cigar as you go. Leave boxed cigars in their boxes and rotate the boxes instead. Do it while you are in there for the inspection, and close the lid promptly. Twenty minutes admiring the collection costs more humidity than the rotation gains.

Nine jobs, nine clocks

Every number on this page is one the app already holds. It counts the rest, checks your readings against your target, and warns at 24°C. Nine maintenance jobs run on their own clocks, from the weekly hygrometer check to the annual wipe-down. Where the app has nothing to go on, it says so.
