So you’re a fan of good wine, and you’ve just acquired a nice bottle. It’s not something you’re going to drink right away, and perhaps you want to put it down for a while and let the passage of time potentially improve what’s inside. If this is your first time cellaring a bottle of wine, it might seem like a confusing task: Where’s the best place to keep your bottles? What about light or temperature? Should a bottle be stored on its side, or standing up? If you’re ready to start a wine cellar of your own, here are some basic instructions for how to get the most out of your bottles.

For temperature, it’s best to keep things cool, but not too cool. In general, people drink reds too warm and whites too cold, and this is extended over to how the bottles are stored, as well. If the temperature in your cellar or wine refrigerator is too high, the wine will age far too quickly, and the aromas and flavors could be dulled by the heat. Too cold, and the tastes and aromas contained in the bottle won’t evolve much at all. In general, a good cellar keeps a temperature of around 50° to 60° Fahrenheit, which is just right to keep a bottle of wine steadily aging for a long time. Just as important as the ideal temperature is that that temperature remains more or less steady. Obviously most of us can’t afford a perfectly regulated wine cellar, but kept somewhere with a consistent temperature will do bottles good.

Light, or lack thereof, is another important factor in a good wine cellar. Specifically, ultraviolet light can have a detrimental effect on wine, so if complete darkness isn’t a possibility, at least keep the bottles away from the sun. UV light can bleach not only the bottle’s label, but the wine itself, leaving it tasting thin and unpleasant. Light from bulbs carries much less UV than the sun does, and all the better if you’re using incandescent bulbs, which emit almost no UV light at all. But if it’s possible, it’s best to keep your cellar dark when you’re not around; if no light gets in, your bottles are better off.

If you go to a good wine shop, you may notice that the higher-end bottles are stored slanted, or on their side. This is how you should keep your bottles in your own personal cellar, as well. The idea here is that if a bottle is kept on its side, the wine will keep the bottom of the cork moist. A dry cork will get loose and let air in, which will cause the wine within to prematurely oxidize, which will lead to that often awful vinegar taste you get from a bottle past its prime — not to mention it can be a frustrating task trying to extract a dry, brittle cork from a bottle. Obviously, this only matters for bottles with corks, so if you have a nice screw top bottle on hand, it can stand up if you feel the need.

So, light, temperature, and bottle placement are probably the three most important factors in a good wine cellar (if you have some especially old bottles, or some well-aged vintage ports, you’ll also want to make sure your bottles aren’t jostled in any way, as this will disturb any sediment that may collect in the bottle). Of course, not all of us are blessed with spacious basements that fulfill all of the requirements for a perfect cellar. If a cool, dark basement isn’t possible, consider a little-used closet, or a quiet corner of a room that doesn’t get a lot of light. Keep your bottles cool, on their side, and in the dark, and you’ll be able to age your wines comfortably. Happy drinking!
