How to Store a Collectible Wine to Preserve Its Value

Owning a rare bottle is only half the story—the other half is storing it correctly. A collectible wine can appreciate in value over time, but only if kept under optimal conditions. Here’s what you need to know to protect your bottles for the long haul.

Constant temperature: never above 18°C

Wine is sensitive to temperature changes. The ideal range is between 10°C and 14°C, with consistency being key. A stable 16°C cellar is better than one fluctuating from 12°C to 18°C. Heat accelerates ageing, while extreme cold can harm the cork.

Humidity: a frequently overlooked factor

A crucial but often ignored aspect is relative humidity, which should stay between 65% and 80%. Low humidity dries out corks, letting in oxygen and oxidizing the wine. Too much humidity promotes mold on the label and capsule. Professional storage facilities, like those used by serious collectors and platforms, control humidity with great precision.

Bottle position: always horizontal

Storing bottles on their side keeps the cork moist and flexible, preventing it from drying out and compromising the seal. Vertical storage over long periods can lead to spoilage.

Light exposure

Light, especially sunlight, is harmful to wine. UV rays can alter both color and aroma. The ideal storage is a dark space, or at least one with dim LED lighting and no direct exposure.

Vibrations and odors

Even low-level vibrations from fridges or appliances can gradually disturb the wine. Avoid storing bottles near strong smells or chemicals: cork is porous and can absorb unwanted scents.
