Is Your Cellar Suitable For Wine Storage
By Melanie Hudson

There are three storage golden rules to follow! cellar has to be dark, humid and cold. All of those three conditions are crucial for right aging of your wine. Why is light so damaging for wine? is an organic liquid. And each carbohydrate organic compound like proteins is sensitive to ultraviolet (UV) light. What will UV light do to wine? It will cause complex organic molecules in to dissolve and they will start to ruin the flavor and the natural aging process of wine. The same effect will excessive sunbathing have on your skin. Ultraviolet light, as a part of sunlight is degrading proteins in our skin. The effects are well known. In extreme cases UV light can cause uncontrollable growth of cell structures leading to skin cancer.

Those who want to buy a ready-made cellar unit with integrated cooling and humid control center should also pay attention to the light source provided within. Neon light emits much more UV light than a classical light bulb. It may not make a difference for bottles that will be consumed within a year. But for storage of bottles that can age for centuries, those short periods of UV exposures within 10 or more years, quickly sum up.

Why should you pay attention to humidity in your cellar? Humidity is important for storing bottles traditionally sealed with cork. Despite the fact that there are many other sealing materials on the market, you will not find a serious top producer using anything other than a cork. What is the relationship between the cork and the humidity? The cork has to be in regular touch with humidity on both sides. That means the inner side, reaching into the bottle has to be in contact with the (that is why cellar storage racks will store horizontally), the outer side of the cork has to be in environment humid enough to prevent cork from drying. A dry cork becomes porous and the air starts to leak into the bottle, spoiling the wine. How will you know if you cellar is humid enough? Relative humidity in a room can be measured with humidity meters called hydrometers. Those are really cheap and easy to buy in any storage accessories store. What is humidity important for a perfect aging process? According to French experts and scientist, perfect humidity level of a storage cellar lays between 60-70%. But more than humidity levels in a cellar, the quality of cork itself is the crucial factor in preventing the from leaking or from spoiling.

If you ask any expert on the world which from those three golden rules plays the most important role in fine aging, they would unanimously say-The Temperature. The best temperature for storage is traditionally believed to be 55°F or 13°C. Little research has been made to discover why exactly that temperature. But more than the temperature itself, it is important not to let the temperature fluctuate for more than 1 degree. Quality needs stable conditions to gradually develop its best aroma, taste and color.
