Wine storage is more than just a matter of keeping bottles cool and dark; the position of the bottle plays a vital role in maintaining the wine's quality over time. The primary reason wine is stored on its side is to keep the cork moist.
What Happens if the Cork Dries Out?
A dried-out cork is the enemy of good wine. Here's why:
- Air Leaks: The cork is the primary seal preventing oxygen from entering the bottle. A dry cork shrinks and cracks, creating pathways for air to reach the wine. Oxygen exposure leads to oxidation, causing the wine to taste stale, flat, and develop undesirable flavors, ultimately ruining it.
- Spoilage: Besides oxygen, airborne bacteria and other microorganisms can also enter through a compromised cork, leading to spoilage and potentially making the wine undrinkable.
Keeping the Cork Moist: The Sideways Solution
Storing wine horizontally ensures the cork remains in constant contact with the wine. This keeps the cork saturated, preventing it from drying out and shrinking. This simple act significantly extends the life and quality of the wine.
Does it Matter for All Wines and Closures?
While the sideways storage method is crucial for wine bottles sealed with natural cork, it's not as critical for all wines.
H2: What about screw caps or synthetic corks?
Wines sealed with screw caps or synthetic corks are less susceptible to oxygen ingress. These alternative closures are generally airtight and don't require the same level of moisture maintenance as natural corks. Therefore, storing these wines on their side isn't strictly necessary, though it won't harm them. Many winemakers opt for upright storage for wines with these closures for space-saving reasons.
H2: Does the angle matter?
While storing the bottle completely horizontal is ideal, a slight angle won't significantly impact the cork's moisture. The key is to ensure the cork remains in contact with the wine.
H2: Should I store sparkling wine on its side?
No. Sparkling wines, due to their higher pressure, should be stored upright. Storing them on their side could lead to excessive pressure on the cork, potentially causing it to pop.
Beyond the Cork: Other Benefits of Horizontal Storage
While cork moisture is the primary reason, horizontal storage offers some additional, albeit less significant, benefits:
- Sediment Distribution: As wine ages, sediment forms. Storing the bottle horizontally keeps the sediment evenly distributed, preventing it from concentrating at the bottom and potentially impacting the wine's taste.
- Label Preservation: While less of a concern, horizontal storage can help prevent label damage from prolonged exposure to light and moisture.
In conclusion, storing wine on its side is a time-honored practice primarily focused on preserving the cork's moisture and maintaining the wine's quality. While not essential for all wines, particularly those with alternative closures, it remains a crucial aspect of proper wine storage for bottles sealed with natural cork.
