Common wine storage mistakes
Most of us don't store wine in a medieval stone cellar – and we don't need to. But there are a handful of common mistakes that can ruin a wine long before you planned to open it. The good news: every single one is easy to avoid once you know about it. Here are the ten mistakes we see most often – and what you can do instead.
1. Storing at Too High a Temperature
This is the most common and most damaging mistake. Wine stored above 70°F (21°C) ages too quickly, resulting in flat aromas, lost fruitiness, and a "cooked" taste. At very high temperatures, the cork can push out of the bottle entirely.
The ideal storage temperature is 50–59°F (10–15°C), with 55°F (13°C) as the golden mean. But what matters most isn't hitting the exact right degree – it's that the temperature stays stable. A wine stored at a steady 64°F will fare better than one that swings between 54–68°F daily.
What you can do: Avoid placing wine on top of refrigerators, near ovens, or in rooms that heat up during summer. A closet on the cooler side of your home is often a better option than the kitchen. Read more in our guide What Should You Consider When Storing Wine?.
2. Temperature Fluctuations
Even if the average temperature is fine, big swings can be devastating. When the temperature rises, wine expands and pushes air out past the cork. When it cools again, air is drawn back in. The result: gradual oxidation that steadily destroys the wine.
This doesn't mean the temperature can never change – slow seasonal shifts of a couple of degrees are no problem. What's dangerous is rapid change, like a bottle sitting in direct sunlight during the day and cooling down at night.
What you can do: Choose a storage location with the most consistent temperature possible. If you don't have a wine cooler or cellar, avoid spots near heat sources and windows with direct sun.
3. Storing Bottles Upright
Bottles with natural cork should lie on their side. The reason is simple: when wine is in contact with the cork, it keeps the cork moist and slightly swollen, creating a tight seal. A cork that dries out shrinks and lets air in, leading to oxidation.
This doesn't apply to all wines. Bottles with screw caps or synthetic corks can stand upright without issue. And wines you plan to drink within a week or two are obviously fine standing in the fridge.
What you can do: Get a simple wine rack. It doesn't need to be expensive – a basic wood or metal rack costs very little and solves the problem completely.
4. Sunlight and UV Exposure
UV light breaks down chemical compounds in wine and creates unpleasant flavors, a condition known as "light strike." White and sparkling wines are especially vulnerable, but all wines are affected. This is why wine bottles are typically made from dark-colored glass.
Even indirect sunlight can be a problem if it heats up the bottles. And fluorescent lights emit small amounts of UV radiation, though it's usually not enough to damage wine under normal exposure.
What you can do: Store wine in darkness. A closed closet, a cabinet, or a wine cooler with a solid door (not a glass door without UV filtering) all work well.
5. Vibrations
Constant vibrations disturb the sediment in wine and can potentially affect the aging process negatively. While it takes quite a lot of vibration to actually ruin a wine, it's best to avoid unnecessary shaking.
The most common vibration sources at home are washing machines, dryers, refrigerator compressors, and loud music with heavy bass. Even a wine rack placed directly on a floor with heavy foot traffic can be problematic.
What you can do: Don't put your wine rack in the laundry room or right next to the fridge. If you have a wine cooler, choose a model with minimal compressor vibration (or thermoelectric cooling for small collections).
6. Long-Term Storage in the Fridge
A regular kitchen fridge runs at about 39°F (4°C) – considerably colder than the ideal wine storage temperature. On top of that, fridges have very low humidity (around 30–40%), and the compressor creates constant vibrations.
In short: your refrigerator is designed to keep food fresh, not to age wine. For keeping a white wine cold before dinner, it works perfectly. But storing bottles in the fridge for months risks drying out the cork and muting the wine's aromas.
What you can do: Use the fridge for short-term storage (days to a couple of weeks at most). For wines you want to keep longer, invest in a wine cooler with temperature and humidity control, or find a cool, dark spot in your home. Read more in our guide on Choosing the Right Wine Storage Solution.
7. Ignoring Humidity
Humidity is the forgotten factor in wine storage. If the air is too dry (below 50%), the cork can dry out and shrink, letting air in. If it's too humid (above 80%), mold can grow – it rarely harms the wine itself but ruins labels and can affect the outside of the cork.
The ideal range is 50–80% relative humidity, with 60–70% being the sweet spot. In colder climates, dry air is especially a problem during winter, when heated homes can drop well below 30% humidity.
What you can do: If you're storing wine in a dry space, place a bowl of water nearby or use a small humidifier. A hygrometer (very inexpensive) lets you monitor the levels.
8. Storing Near Strong Odors
Wine can absorb smells through the cork, especially during long-term storage. That means your perfect Bordeaux can suffer from sitting next to solvents, strong spices, chemicals, or even perfume.
Kitchens are especially problematic – the combination of cooking fumes, heat, and strong odors makes them one of the worst places to store wine at home.
What you can do: Store wine in a space free from strong odors. Avoid kitchens, laundry rooms, and storage areas with paint cans. Make sure the space is clean and well-ventilated but not drafty.
9. Not Keeping Track of Your Wines
This one isn't about storage conditions – it's about you as the collector. Many wine enthusiasts buy bottles and put them on the shelf without any plan for when to drink them, then simply forget about them.
The result: wines that have passed their drinking window and lost their charm. Not all wines improve with age. The vast majority – an estimated 90% – are made to be consumed within three to five years.
What you can do: Keep your collection organized with a digital tool. Macave helps you log wines with vintage, region, and price, and keeps track of what you have so nothing gets forgotten.
10. Treating All Wines the Same
Different wines have different needs. A light rosé meant to be drunk within six months doesn't require the same care as a Barolo you're planning to age for fifteen years. An expensive Champagne with natural cork has different requirements than an everyday wine with a screw cap.
As a general rule, the longer you plan to store a wine, the more important all the factors above become. For wines you intend to drink soon, you don't need to worry as much.
What you can do: Match your storage to the wine's needs. Short-term wines (drinking within 1–2 years) do just fine in a cool closet. Long-term wines (5+ years) deserve a wine cooler or other stable storage environment. A good starting point is our guide on How to Build a Wine Collection.
Summary
Perfect storage conditions are ideal, but don't let "perfect" be the enemy of "good enough." A cool, dark closet often beats an expensive wine cooler in a hot room. The key principles to remember:
Stable temperature (50–59°F / 10–15°C) matters more than the exact number. Horizontal storage keeps the cork moist. Darkness protects against UV damage. Some humidity (50–80%) prevents the cork from drying out. And above all – keep track of your wines so you drink them at the right time.
