TL;DR
Aim for about 55°F (13°C) and 60-70% relative humidity, with 45-65°F and 50-80% as the safe ranges named sources give. A steady room beats a precise one. Above 70°F wine ages faster than you want. Humidity matters only for natural corks held for years; for most home bottles it is not worth worrying about.
Wine cellar temperature and humidity come down to two numbers: about 55°F (13°C) and 60-70% relative humidity. Named sources accept 45-65°F and 50-80% as safe. A steady room matters more than the exact degree. For most home bottles, Wine Spectator says humidity is not something to worry about.
Wine Cellar Temperature and Humidity at a Glance
Read the last column first: if your storage spot hits any of those triggers, fix that before chasing the exact target. Every figure comes from a named source listed at the end of the page.
| Condition | Aim for | Safe range | Act when |
|---|---|---|---|
| Temperature | 55°F (13°C) | 45–65°F (7–18°C) | It often tops 70°F (21°C), or ever reaches 80°F (26.6°C) |
| Day-to-day swing | The same reading every day | A steady 63–64°F beats 57°F one day and 67°F the next | Readings jump about 10°F (5–6°C) between days |
| Humidity | 60–70% | 50–80% | Below 50% for years with natural corks, or above 80% with mould on labels |
What Is the Ideal Temperature for a Wine Cellar?
About 55°F (13°C), which Wine Spectator says is "often cited as close to perfect." WineFolly gives 55-59°F (12-15°C) and Stag's Leap Wine Cellars 55-60°F (13-16°C), inside Wine Spectator's wider 45-65°F range. If your spot holds steady anywhere in that band, leave it alone. A room planned with the home wine cellar guide can target 55°F without chasing one exact degree.
The number has a cave behind it: Wine Spectator notes that wineries in Bordeaux and Champagne have long stored wine in natural caves because they are cool, humid and dark. Wine writers land in the same band. According to Wikipedia's page on wine storage, Jancis Robinson favours 50-59°F (10-15°C), Tom Stevenson about 52°F (11°C) and Karen MacNeil around 55°F (13°C).
| Source | Temperature | Humidity |
|---|---|---|
| WineFolly | 55–59°F (12–15°C) | 55–75% |
| Wine Spectator | 45–65°F (55°F close to perfect) | 50–80% (70% conventional ideal) |
| Stag's Leap Wine Cellars | 55–60°F (13–16°C) | 50–80% (70% stated ideal) |
| Jancis Robinson | 50–59°F (10–15°C) | 75% often cited, little research |
| Tom Stevenson | About 52°F (11°C) | Not stated |
| Karen MacNeil | About 55°F (13°C) | Not stated |
What Humidity Level Does Wine Actually Need?
Aim for 60-70% relative humidity and accept anything from 50% to 80%. Wine Spectator and Stag's Leap Wine Cellars both call 50-80% safe, with 70% as the conventional ideal, and WineFolly gives 55-75%. Jancis Robinson notes that 75% is often cited, yet very little research pins down an optimal range.
For most home bottles, humidity does not need managing. Wine Spectator puts it directly: "for the vast majority of people, for the vast majority of wines, it's not something to worry about." The reason is the cork itself. Its inner end touches the wine and stays wet, so storage air only reaches the outer end.
Manage humidity only when all three of these are true:
- Natural cork. Screwcaps and glass stoppers have no cork to dry out.
- A long hold. The bottle will sit for several years, long enough for the outer end to dry.
- Dry air. You live somewhere arid, or a hygrometer reads below about 50% for months. A kitchen fridge counts too: Tom Stevenson warns that refrigeration often dehumidifies and can dry corks quickly.
When a cork does dry out, Wine Spectator warns, "it can compromise the seal and prematurely age the wine." Air seeps past the shrunken cork, the fruit fades, and the wine can taste flat or turn brown early. Even with the seal intact, a dry cork can crumble when you pull it and drop pieces into the glass. Wine Spectator suggests a pan of water in the storage area to lift a dry room.
Not every expert agrees that room humidity matters at all. Wine Spectator writer Matt Kramer cited a French study claiming the air inside a bottle stays at 100% humidity whatever the closure or orientation. Alexis Lichine, by contrast, held that low humidity still harms premium wine through dry corks. He suggested half an inch of gravel on the cellar floor, sprinkled with water now and then.
Too much humidity is mostly a label problem. Above about 80% for years, damp air can promote mould on labels and the outer face of the cork, and labels can become hard to read. If you have to err to one side, slightly humid beats slightly dry.
Why Do Temperature Swings Matter More Than the Exact Number?
Wine Spectator ranks rapid, extreme or frequent swings above hitting 55°F. Each swing makes the wine expand and contract inside the bottle, which can push the cork out or let wine seep past it. Stag's Leap Wine Cellars gives the clearest example: a room that holds 63-64°F beats one at 57°F one day and 67°F the next.
The Mattivi study WineFolly reports tested exactly this. Half of 400 bottles of Tuscan wine went into a professional cellar and half into a dark room built to mimic the natural temperature swings of a home closet. After two years the closet wines had lost colour, and the compounds that shield wine from oxygen, about four times faster. They also showed chemical changes that made them more prone to faults.
Small daily drift is not worth losing sleep over. Wine Spectator notes that bottles may see worse in transit from the winery to the shop. If your spot moves more than a few degrees between morning and evening, move the wine before you spend money on a cooler.
What Happens If Your Cellar Gets Too Hot or Too Cold?
Wine Spectator says temperatures above 70°F (21°C) "will age a wine more quickly than is usually desirable." WineFolly treats 80°F (26.6°C) as the ceiling: below it, ordinary storage gives about a year of aging. Long stretches above that produce cooked wine, which tastes stewed and flat.
Heat speeds up the chemical reactions that slowly change a wine's flavour. Wikipedia's summary puts the rate at roughly double for every 18°F (10°C) rise.
A brief spike is more forgiving. UC Davis researcher Cornelius Ough held that wine can take up to around 120°F (49°C) for a few hours without being ruined, per the same Wikipedia summary.
Cold is a smaller problem. Near-freezing storage barely ages wine, which is harmless on its own. The risk is a bottle that actually freezes: the liquid expands and can push the cork out or crack the glass. Wine Spectator names the usual culprits, an unheated garage in winter and a bottle forgotten in the freezer. A bottle chilled for serving is nowhere near that point.
Do You Need to Store Wine on Its Side?
Only for natural-cork bottles you will keep for more than a year or two. Lying down keeps the cork in contact with the wine. Wine Spectator says laying bottles down "is not necessary" for wine you plan to drink soon. If the bottle has a screwcap, glass stopper or plastic cork, stand it upright if that saves space.
Sparkling wine is the debated case. Its gas pressure protects the cork, so Wikipedia's summary notes it tends to age better upright, yet the Champagne trade body (CIVC) still advises storing it on its side. Our screw cap vs cork comparison shows how to tell the closures apart at a glance.
Can You Store Wine Safely Without a Cellar or Wine Fridge?
Yes, for bottles you will open within about a year. WineFolly says ordinary storage gives about a year of aging as long as the spot never exceeds 80°F (26.6°C). If you plan to age bottles for years, or hold more than a dozen long term, buy the steady cold of a wine fridge or build a cellar.
Treat the kitchen fridge as a short stop. Wine Spectator says a household fridge is fine for up to a couple of months, but it runs well below 45°F and its dry air can shrink corks. WineFolly adds that thermoelectric wine coolers, quiet as they are, swing too much in temperature for long-term aging.
Set up the spot in four steps:
- Find the steadiest spot. Read a cheap thermometer morning and evening for a day or two. Rule out the kitchen, laundry room and boiler room, as Wine Spectator advises. An interior closet usually moves less than anything near an exterior wall or a window.
- Check the numbers. Keep it under 70°F most of the time, never at 80°F, and within a few degrees from day to day. Read it again in midsummer and once the heating comes on, when most homes run warmest and driest.
- Keep it dark. Wine Spectator flags sunlight as the main risk for long-term storage. Household bulbs probably will not harm the wine but can fade labels; incandescent bulbs are a little safer than fluorescent ones, which give off small amounts of ultraviolet light.
- Keep it still. Wine Spectator finds little evidence that appliance hum harms wine. Heavy vibration can keep sediment in older wines from settling, which makes them gritty. Keep bottles off the top of a running fridge, which is warm as well as shaky, and see the vibration and wine storage guide for washing machines and deliveries.
For spot-by-spot advice, how to store wine at home tests the usual places in an ordinary house, and the wine cellar alternatives ranking runs from under-bed boxes to wine fridges.
Once a stored bottle reaches the table, serving temperature takes over. The wine serving temperature chart gives the pouring temperature for each style, and how temperature affects wine taste shows what a few degrees change in the glass. When storage goes wrong for long enough, the result is oxidized wine. The serving and storage learning hub collects every related page.
Tonight, set a thermometer in the spot you plan to use, then read it again at the same time tomorrow before you store another bottle there.

Frequently Asked Questions
What is the ideal temperature for a wine cellar?
Aim for 55°F (13°C). Named sources cluster around it: WineFolly gives 55 to 59°F, Stag's Leap Wine Cellars 55 to 60°F, and Wine Spectator a wider 45 to 65°F. Keeping the temperature steady matters as much as the number itself, so pick the spot that moves least from one day to the next.
What humidity level is best for storing wine?
Aim for 60 to 70% relative humidity. Wine Spectator and Stag's Leap Wine Cellars both call 50 to 80% safe and 70% ideal, and WineFolly gives 55 to 75%. Jancis Robinson notes that very little research pins down an exact optimum, so any steady reading inside 50 to 80% is fine.
Do I need a humidifier for my wine cellar?
Usually not. Wine Spectator says humidity is not something to worry about for the vast majority of people and wines, because the inner end of the cork stays wet from the wine. Check with a hygrometer first. A humidifier earns its place only if natural-cork bottles will sit for years in air below about 50%.
Can wine be stored too cold?
Yes, in two different ways. Storage that sits near freezing barely ages the wine at all, which is not damaging by itself, but if the bottle actually freezes, the expanding liquid can push the cork out or crack the glass. Brief chilling before serving is different from long-term cold storage and will not hurt the wine.
Does temperature fluctuation actually damage wine?
It is the risk to fix first. Stag's Leap Wine Cellars says a room that holds 63 to 64°F is better than one at 57°F one day and 67°F the next, even though the second room is cooler on average. Choose the spot that moves least, then worry about the exact number.
Do I need to store wine on its side?
Only for bottles sealed with a natural cork that you plan to keep for more than a year or two. Wine Spectator says this is not necessary for screwcap, glass-stopper or plastic-cork closures, or for wine you will drink soon. Sparkling wine is debated: some experts keep it upright because its gas pressure protects the cork, though the Champagne trade body advises lying it down.
Can I store wine without a cellar or wine fridge?
Yes, for bottles you will open within about a year. WineFolly says ordinary storage gives about a year of aging as long as the spot never goes above 80°F (26.6°C). Pick a dark interior closet away from the kitchen and windows. Wines you want to age for years still need a wine fridge or cellar.
What is the maximum temperature wine can survive without ruining it?
Wine Spectator says anything above 70°F (21°C) ages wine faster than is usually desirable, and WineFolly treats 80°F (26.6°C) as the ceiling for a year of casual storage. A short spike is more forgiving: UC Davis researcher Cornelius Ough held that wine can take up to 120°F (49°C) for a few hours without damage.
