How to Store Cigars: The Humidor & 70/70 Guide

Here's a stat that should make you close the lid on that desktop humidor: according to Boveda's official RH guide, cigars only keep their essential oils — the stuff that gives you flavor and aroma — between 65% and 72% relative humidity. Outside that window, you're not aging cigars. You're ruining them slowly.

The good news? Storing cigars the right way isn't complicated. It's a humidor (or a $10 tupperdor), the right humidity pack, and about five minutes a month. This guide covers the famous 70/70 rule, how to season a humidor, and the fixes for when things go sideways.

What Is the 70/70 Rule for Storing Cigars?

The 70/70 rule is the old-school benchmark for cigar storage: 70 degrees Fahrenheit and 70% relative humidity. Cigars International's Humidors for Beginners guide recommends holding humidity around 68–72% and rotating your cigars to keep mold from getting a foothold. Stay in that zone and your sticks stay firm, oily, and ready to smoke.

Why does the number matter so much? A premium cigar is a hygroscopic little sponge — it absorbs and releases moisture based on whatever room you leave it in. Too dry and the wrapper cracks, the oils evaporate, and the smoke turns hot and bitter. Too wet and you get tight draws, canoeing burns, and eventually mold.

That's also why the traditional humidor is lined with Spanish cedar. Per the same Cigars International guide, the wood is naturally resistant to insects, holds humidity beautifully, and adds a subtle aroma cigar lovers have prized for over a century. If you're just getting started, our beginner's guide to smoking a cigar covers the whole ritual from first cut to final third.

Is 70/70 Still the Best Way to Store Cigars?

Honest answer: 70/70 is a fine rule, but most serious smokers now run a notch drier. Cigar Advisor at Famous Smoke Shop makes the case in its 70/70 myth breakdown that a lower RH — think 65–69% — often gives you a better burn, an easier draw, and a wider safety margin against mold.

Boveda lands in the same neighborhood, calling 69% its most-preferred RH for premium cigar storage. And here's a rule worth tattooing on your humidor lid: pick one humidity level and stick with it. Mixing different RH packs in one box creates a tug-of-war that ruins the environment for everything inside.

Ever pulled a cigar that felt like a dry twig, or one so spongy it wouldn't stay lit? That's the difference a few percentage points make. Our crew keeps house humidors at 65% year-round, and the difference in burn consistency compared to the old 70% days is real — especially in a humid Gulf Coast summer.

How Do You Season a New Humidor?

A brand-new wooden humidor is bone dry, and loading cigars into it immediately is the fastest way to wreck them — the thirsty cedar will pull moisture straight out of your sticks. Cigars International's seasoning walkthrough has you humidify the wood itself first, and the process takes a few days of patience.

The short version:

• Wipe or place, don't soak. Use distilled water only — tap water carries minerals and microbes that can cause mold and white crust. Set a shot glass of distilled water or a damp new sponge inside, or use a purpose-made seasoning pack.
• Close the lid and wait. Give the cedar two to three days to drink up moisture. Longer is better.
• Calibrate your hygrometer. A salt test or a calibration kit tells you whether that needle is lying to you. Many analog hygrometers read several points off out of the box.
• Then load your cigars. Once the box holds a steady RH, add your sticks and your humidification source.

What Temperature Keeps Cigars Safe From Beetles?

Keep your cigars at 61–65°F (16–18°C). That's the official storage guidance from Habanos S.A. in its Keeping Habanos guide, which pairs that range with 65–70% humidity — and warns that sustained temperatures above 18°C (65°F) can let dormant tobacco beetle eggs hatch and become active.

Tobacco beetles are the horror story of cigar collecting. The eggs travel invisibly inside tobacco leaf, and warm storage is the incubator. If you ever spot pinholes in a wrapper and fine dust in the box, you've got beetles — and the whole humidor needs quarantine.

Two more temperature rules save collections. First, keep the humidor out of direct sunlight and away from vents; swings in temperature are as damaging as heat itself. Second, Habanos S.A. recommends taking cigars out of their aluminum tubes for long-term storage, since tubed cigars can't breathe or age evenly. Want the full pre-smoke ritual once they're rested? Here's how to cut a cigar properly.

No Humidor Yet? Tupperdors and Quick Fixes Work

Don't let a missing humidor stop you — an airtight food container plus a two-way humidity pack does the same core job for under fifteen bucks. The "tupperdor" holds RH more consistently than many cheap wooden boxes because the seal is genuinely airtight. Toss in a cedar sheet and it even smells the part.

Storing a handful of sticks short-term? A zip-top freezer bag with a humidity pack keeps cigars smokeable for weeks. What you should never do is refrigerate them — the fridge is a dehydrator, and the cold dulls the oils you're trying to protect.

One caveat for the budget route: an overfilled or near-empty container makes humidity swing harder, so size the box to your stash. Ready to fill it with something worth aging? Start with our picks for the best cigars for beginners.

How Do You Maintain a Humidor Month to Month?

Five minutes a month keeps a humidor healthy. Cigars International's beginner guidance is to hold RH in that 68–72% band (or your chosen lower target) and rotate cigars regularly — swap the top row with the bottom and move edge cigars toward the center so every stick ages evenly.

Your monthly checklist: verify the hygrometer reading, recharge or replace humidity packs when they start feeling stiff, rotate the sticks, and crack the lid for a minute of fresh air. Twice a year, re-check hygrometer calibration. If RH drifts low and stays low, re-season the box — dried-out cedar can't hold moisture no matter how many packs you throw at it.

How do you know it's all working? The pinch test: a well-kept cigar gives slightly under the fingers and springs back, the wrapper shows a faint oily sheen, and it lights evenly without fighting you. That's the payoff for the patience. And if your family ever questions the size of your stash, the "Yes I Really Need Cigars" tee answers for you.

Frequently Asked Questions

What is the 70/70 rule for cigars?

The 70/70 rule is the traditional benchmark of 70°F and 70% relative humidity for cigar storage. It's a safe starting point, though many experts — including Cigar Advisor at Famous Smoke Shop — now recommend running slightly drier, around 65–69% RH, for a better burn and less mold risk.

Is 65% or 70% humidity better for cigars?

Both sit inside the safe 65–72% range Boveda publishes, so it comes down to preference. Lower RH around 65% gives an easier draw, crisper burn, and more mold protection; 70% keeps cigars softer and more moisture-rich. Pick one level, stick to it, and never mix humidity packs.

How long can cigars last in a humidor?

Kept at a stable 65–72% RH and under 65°F, premium cigars can rest for years — and many actually improve with age as flavors marry and mellow. The keys are consistency, a calibrated hygrometer, and regular rotation so every cigar in the box ages at the same pace.

Can you store cigars without a humidor?

Yes — an airtight food container with a two-way humidity pack (a "tupperdor") works remarkably well, and a zip-top bag with a pack handles short-term storage for weeks. Avoid the refrigerator entirely; it dries cigars out and dulls the oils that carry flavor and aroma.

What temperature should a humidor be?

Aim for 61–65°F (16–18°C), the range Habanos S.A. recommends. The critical ceiling is 65°F — sustained warmth above that can hatch dormant tobacco beetle eggs hiding in the leaf, and a beetle outbreak can chew through an entire collection in days.

The Bottom Line

Storing cigars well comes down to three numbers: 65–72% humidity, temperatures under 65°F, and a few days of seasoning before a new box earns your trust. Nail those and every cigar you light will smoke the way its blender intended.
