Wine storage is more than just keeping bottles cool; it's about preserving the quality and integrity of the wine inside. One of the most common practices, particularly with aged wines, is storing them on their sides. But why? The simple answer is to keep the cork moist. Let's delve deeper into this essential aspect of wine preservation.
Why is it important to keep the cork moist?
The cork is the primary seal protecting your wine from oxygen, the ultimate enemy of wine quality. Oxygen exposure can lead to oxidation, resulting in undesirable changes in the wine's flavor and aroma profile, often described as "off-flavors," including notes of vinegar or sherry. A dried-out cork can shrink, allowing air to enter the bottle and spoil the wine. Keeping the cork moist prevents this crucial shrinkage.
How does storing wine on its side keep the cork moist?
When a wine bottle is stored upright, gravity pulls the wine away from the cork, causing the upper part of the cork to dry out. Storing the bottle on its side allows the wine to maintain consistent contact with the cork, keeping it saturated and preventing it from drying out and shrinking. This ensures a tight seal, preventing oxidation and preserving the wine's quality.
What happens if you store wine upright?
While storing wine upright is perfectly fine for short-term storage (e.g., a few weeks), long-term storage in this position significantly increases the risk of cork shrinkage and the subsequent ingress of oxygen. This results in accelerated aging and, eventually, spoilage of the wine. Therefore, for wines intended for aging, lateral storage is highly recommended.
Is it necessary to store all wines on their side?
Not all wines require side storage. Younger wines, those intended for immediate consumption, are less susceptible to cork dryness and oxidation. However, it's generally a good practice, especially if unsure, to store all wines on their sides for optimal preservation.
What are the other factors that affect wine storage?
Besides storing wine on its side, several other factors impact the quality and longevity of your wine:
- Temperature: Consistent cool temperatures between 55°F and 60°F (13°C and 15°C) are ideal. Fluctuations in temperature should be avoided.
- Humidity: Ideally, aim for 50-70% relative humidity to prevent the cork from drying out or becoming excessively moist.
- Light: Protect wine bottles from direct sunlight and ultraviolet (UV) light, as these can negatively affect the flavor and color of the wine.
- Vibration: Avoid storing wines in areas with significant vibrations, as this can agitate the wine and potentially impact its quality.
Does the type of closure matter?
While the information above primarily focuses on corked bottles, it's worth noting that the necessity of side storage diminishes with alternative closures like screw caps, synthetic corks, or DIAM corks. These closures are less susceptible to drying out and offer better oxygen protection, allowing for more flexible storage positions.
By understanding the importance of keeping the cork moist and implementing proper storage techniques, you can significantly enhance the lifespan and quality of your wine collection. Whether you are a seasoned connoisseur or a casual wine drinker, employing these methods ensures that your treasured bottles remain at their peak for your enjoyment.
