Peugeot Clef du Vin

The device features a patented metal alloy that triggers an oxidation process when it comes into contact with wine. This interaction accelerates the chemical changes that occur naturally over time in a cellar, allowing you to taste the wine's potential maturity instantly.

No, the process is irreversible and cumulative. Once you have dipped the tool into the wine, the aging effect cannot be undone, so it is best to test in small increments.

Each second of contact with the wine represents approximately one year of cellar aging. We recommend starting with a very brief dip and tasting as you go to avoid over-aging the wine.

Yes, the Clef du Vin is compatible with sparkling wines, including Champagne. It will age the flavor profile without significantly impacting the effervescence of the wine.

It is designed to work with all varieties, including reds, whites, rosés, sparkling, and sweet wines. Because every wine reacts differently to oxidation, the results will vary depending on the specific bottle's structure and age.

The tool is very low maintenance. Simply rinse it with clean water after each use and dry it thoroughly before storing it in its case to ensure the alloy remains effective for future tastings.
