Optimal conditions to store wine and preserve it in your cellar

Wine storage conditions: conservation and aging

Once you have purchased your wine bottles, a minimum of rigour is required to ensure their preservation. The essential parameters are listed below to define the ideal framework for wine storage and long-term conservation.

• The first is the temperature at which your wine is stored: it must remain constant and cool, between 10 and 14 °C. Thermal shocks damage wine preservation; the alternation of cold and warmth causes the cork to lose elasticity, reducing its effectiveness and allowing oxygen to enter, which will oxidize your wine.
• Secondly, each wine bottle must be stored lying down (not upright) so the cork remains in permanent contact with the wine and does not dry out. Never move or turn bottles in your storage area, as vibrations accelerate wine deterioration and oxidation.
• The third requirement is humidity (hygrometry): it must remain between 70 and 80 per cent. This moisture level is essential for the cork—it allows your wine bottle to breathe and prevents cork drying. If humidity falls below 70 per cent, oxidation risk increases; if it exceeds 85 per cent, mould growth and musty odours develop and transfer to your wine through the cork.

When ambient humidity is too high, labels deteriorate and musty odours develop—odours that transfer to your wine through the cork. The final requirement is the absence of light: ultraviolet radiation accelerates oxidation and hastens wine evolution. In summary: maintain constant temperature, stable humidity, protect wine from light, and store bottles lying down without movement. Follow these storage conditions and your wine will reach peak drinking quality.

How to store wine in optimal conditions: wine cellars and preservation solutions

If you lack a naturally dark, cool cellar with constant temperature, wine storage solutions exist. A dedicated wine cellar furniture meets all optimal conditions for bottle storage and long-term wine preservation. These systems, sized for your collection, are easily installed in kitchens, laundry rooms, or spare spaces. Whether you store a small collection or large bottles, a wine cellar is the ideal tool for serious enthusiasts.

Preserving open wine bottles: champagne, white, and red wine solutions

Open wine preservation depends on the wine type. Preservation strategies differ for still white, rosé, and red wines—and champagne requires its own specialized approach.

• White and rosé wines preserve best when stored at cool temperatures; 14–15 °C is ideal for maintaining aromas and taste.
• Red wine preservation is more complex. Depending on winemaking and grape variety, keeping red wine open beyond a few days requires specialized preservation systems.

Vacuum stoppers work by extracting air, but the process removes an unpredictable amount of oxygen—and crucially, removes tannins and aromas along with it, damaging the wine. Professional wine preservation uses inert gas cartridges (Argon and CO2), the same principle employed during winemaking: gases displace oxygen without removing aromatic compounds, protecting wine from oxidation. Unlike vacuum systems, inert gas preserves both flavour and aroma. Maintaining constant temperature remains essential during open-bottle preservation.

How long can open wine last? Storage duration with inert gas preservation

With inert gas preservation systems, an open bottle of red wine can be preserved for up to two weeks without altering aromas or taste. This is how professionals serving wine at tastings or winery visits preserve wine quality across multiple days of service. The Wikeeps system extends this preservation principle: place the Wikeeps stopper on your open wine bottles during tastings to protect wine from oxidation and enjoy them for several days without quality loss.
