The Best Way to Store Unopened Champagne: Tips for Optimal Preservation
Champagne is a precious and delicate wine that requires proper storage to maintain its quality until it is enjoyed. Follow these guidelines to ensure your bottle remains in its best condition.
Temperature
The ideal temperature for storing unopened champagne should be between 45°F (7°C) and 65°F (18°C). Consistency is key, as temperature fluctuations can negatively impact the quality of the wine. Keep your champagne away from sources of heat such as radiators, ovens, or direct sunlight, which can cause the temperature to rise abruptly.
Position
Store your champagne bottles horizontally. This position keeps the cork moist, preventing it from drying out and allowing air to enter the bottle. A moist cork ensures that the pressure inside the bottle is maintained, preserving the sparkling nature of the champagne. Most French champagne houses store their bottles in a-horizontal position in temperature/humidity stable cellars, a method that has stood the test of time.
Somewhat surprisingly, some experts suggest that the cork will not dry out due to the bottle’s internal humidity if the bottle is stored upright. However, the pressure inside the bottle can still help maintain the seal. Some Champagne corks are laminated with a thin 2–3mm bottom layer of cork and a resorcinol-based glue, which forms a seal independent of the rest of the cork. This means that cheaper cork can be used for the mushroom-shaped part of the closure, potentially making production more cost-effective. However, while this may be true, your preference should also be respected. I still store my bottles horizontally as I have done so for several years without issues.
Light
Champagne should be stored away from direct sunlight and bright artificial light. UV rays can degrade the wine and affect its flavor. Keep your bottles in a cool, dark place to preserve their quality and flavor.
Humidity
Opt for a relative humidity level of around 70%. Maintaining a proper humidity level is important for the integrity of the cork, preventing it from drying out and compromising the seal. A stable humidity level will help ensure that the champagne remains in optimal condition until you're ready to open it.
Vibration
Champagne should be stored in a stable environment without vibrations. These can disturb the sediment and affect the wine's taste. Vibrations can cause the sediment to rise to the top of the bottle, potentially resulting in a sediment-laden pour.
Duration
The storage duration for champagne varies depending on the type. Non-vintage champagne can typically be enjoyed within a few years of purchase, while vintage champagne can often be stored for longer periods. Generally, it is best to consume non-vintage champagne within 3-5 years and vintage champagne within 5-10 years. However, some varieties can age even longer.
By following these guidelines, you can help ensure that your champagne maintains its quality until you are ready to enjoy it. Whether you store your champagne in a cellar or a stable environment in your office, the key is to maintain consistent conditions to preserve its delicate qualities.
As you can see, maintaining the proper storage conditions for champagne is a bit of a science. Whether you store your bottles horizontally or upright, the key factors are temperature, humidity, and avoiding vibrations. My personal preference is to store them horizontally, as I have for several years without issues. However, some people believe that the cork will not dry out due to the bottle's internal humidity if it is stored upright. If you decide to try this method, I invite you to share your experience.
My champagne habit is quite significant, around 3-4K annually, not including the other bottles of sparkling wine from other countries. I prefer Kiwi bubbly over Australian, but there are a few great American sparkling wines as well. If your wine store stocks Argyle from Oregon, I strongly recommend giving it a try.
