Should wine be stored on its side? For cork-sealed bottles you plan to keep more than a few months, yes: Purdue Extension and Wine Spectator both recommend it. For screw caps, bottles you will open soon, and spirits, upright is fine or even better. A cork industry scientist argues the side position matters less than most people think. Here is what the sources say and which rack orientations keep the cork wet.
Should wine be stored on its side? The short answer
| Bottle | Short term (weeks to a few months) | Long term (a year or more) |
|---|---|---|
| Natural cork | Upright is fine | On its side |
| Synthetic cork | Upright is fine | On its side (Purdue includes synthetic corks) |
| Screw cap or glass stopper | Any position | Any position; side storage is fine and saves space |
| Sparkling wine with cork | Upright is fine | On its side is the common advice |
| Whisky and other spirits | Upright | Upright |
Why corked wine is stored horizontally
The classic reason is cork moisture. Dr. Vinny explains in a Wine Spectator answer that a cork that dries out “can shrink and let air into the bottle,” which oxidizes the wine so it ages early and its flavors fade. On its side, the inner end of the cork stays in contact with the wine. For the outer end, he suggests a cellar at around 70 percent relative humidity.
Purdue Extension’s Wine Storage Guidelines (FS-58-W) give the same advice from a gas exchange angle: bottles closed with corks, “both bark or synthetic,” should be stored upside down or sideways “to minimize the gas exchange between the outside atmosphere and the wine inside to avoid accelerated oxidation.”
The cork moisture debate
Not everyone agrees on the mechanism. In 2018, The Drinks Business reported comments from Dr. Miguel Cabral, then director of research and development at cork producer Amorim, who called side storage to stop cork drying a myth. His argument: the air gap (headspace) inside a sealed bottle sits near 100 percent humidity, so “the cork will never dry out,” even upright, and the humidity of the room around the bottle “won’t have any influence.” He also suggested a cork soaked in wine all the time might weaken faster.
How to square the two views in practice:
- Both sides agree the cork has to keep sealing. The disagreement is over whether contact with the wine is what keeps it sealing.
- Side storage costs nothing. Wine Spectator’s storage tips call horizontal racking space efficient and say it “definitely can’t harm your wines.”
- Temperature matters more. Purdue says temperature swings “test the integrity and position of the bottle closure, especially corks.” A steady temperature does more for a cork than any angle. Our wine storage temperature guide covers the numbers.
Our take: for bottles you are aging for years, lay them down. You lose nothing and follow the advice of Purdue and, per Dr. Vinny, most producers.
Can you store wine upright?
Yes, for a while. Dr. Vinny writes in a separate answer that it takes “more than a few weeks or even months” upright before the cork in a recently released bottle shows signs of age, which is why shops can stand bottles up. The storage tips article adds that side storage is not necessary for wines you will drink in the near to mid term.
What about upside down or tilted?
Dr. Vinny says upside down beats upright for keeping the cork wet, but sediment collects on the cork and leaks become more likely, so horizontal is still his pick. On 45 degree display racks, he found wine still touches the cork in most bottles at that angle: better than upright, not as good as fully on the side.
Screw cap wine storage and synthetic corks
Screw caps do not depend on moisture to seal. Dr. Vinny says side storage is “not necessary” for screw caps “but it also doesn’t hurt.” In another column he adds that most producers recommend storing all bottles on their side, “even ones with glass, plastic or metal toppers,” simply because there is no advantage to upright.
Synthetic corks are a different case. Purdue groups them with natural cork in its sideways or upside down advice, so treat them like cork.
Sparkling wine and Champagne
Some collectors keep Champagne upright, on the theory that the pressurized gas keeps the cork moist. Dr. Vinny notes sparkling wine holds about 70 to 90 psi, which makes the bottle “naturally more humid inside,” but still says any wine topped with a cork should be stored on its side. Purdue warns that heat raises that pressure sharply and has burst sparkling bottles, so a cool spot matters more than the angle.
Champagne bottles are wider than standard 750 ml bottles. The VintageView W Series Mag Rack ($120 single deep) holds 9 magnums or Champagnes horizontally, with Champagne bottles spaced 7.5 inches apart. Our wine bottle dimensions guide has the sizes.
Spirits: store upright
Whisky and most spirits are the exception. Whisky Advocate’s collection storage guide says to store bottles upright and never on their side, because “contact with the high strength alcohol could cause the cork to degrade or impart unpleasant flavors.” Keep spirits on a shelf, not in a wine rack.
How to store wine bottles: rack orientations compared
Every orientation below keeps the bottle horizontal or close to it. The difference is what you see and how much wall it takes. Prices are our current listed starting prices and match VintageView’s own listed prices on vintageview.com when we checked, so you will not save by buying direct for these items.
| Orientation | How the bottle sits | Example | Price from |
|---|---|---|---|
| Label forward | On its side, parallel to the wall, slight angle, label out | W Series Wine Rack 3, 9, 18 or 27 bottles | $123 |
| Cork forward peg | On its side, neck pointing out of the wall | Vino Rails 1, 1 bottle | $16 |
| Cork forward, tilted | Column of rails, straight or tilted up to 45 degrees | Vino Rails Flex 45, 9 bottles | $194 |
| Presentation | Label forward, resting bottom first so it tilts toward you | W Series Presentation Row | $63 |
| Presentation, rods | Display row on the Evolution system | Evolution Wine Wall Presentation Row, 3 to 9 bottles | $110 |
| Cork forward bulk | Bottles stacked side by side, cork out | Case & Crate Bin 3, 48 bottles | $435 |
For long aging, the fully horizontal options (label forward rows, cork forward pegs, bins) are the safest bets. Presentation rows and steep tilts are best for a few bottles you will open soon, in line with Dr. Vinny’s 45 degree answer. Our label forward vs cork forward guide compares wall depth and capacity in detail, and the wine rack depth guide covers 1, 2 and 3 deep spacing. Browse all VintageView racks.
Short term vs long term: a simple plan
- Drinking within a few months: any position, any steady spot out of the sun and heat.
- Keeping a year or two: lay corked bottles down in a cool, steady room.
- Aging for years: on their side, at cellar temperature, ideally in a wine fridge or cooled room. See our wine rack vs wine fridge guide.

Frequently asked questions
Does storing wine horizontally vs vertically really matter?
For corked wine kept a year or more, most guidance says horizontal. A cork industry scientist argues the headspace keeps the cork moist anyway, but side storage does no harm.
Can you store wine upright for a few months?
Yes. Wine Spectator’s Dr. Vinny says it takes more than a few weeks or even months upright before a recent release’s cork shows signs of age.
Do screw cap wines need to be stored on their side?
No. Any position works, though side storage is fine and often saves space.
Is a 45 degree display rack bad for wine?
Not for most bottles. Dr. Vinny found wine still touches the cork at 45 degrees, though fully horizontal is better for long aging.
Should whisky be stored on its side like wine?
No. Whisky Advocate says to store whisky upright, because high-proof spirit can degrade the cork.
