Clef du Vin

The Clef du Vin is an alloy made up of many different metals, which have been prepared and produced using a special technique. Using a Clef du Vin, or "wine key", helps simulate the passage of time on a bottle of a wine. Dipped in a glass of wine one second for every year of aging desired, the metal alloy speeds the oxidation process changing the wine's taste, in effect mimicking the effect of cellaring. Wine collectors will also use the Clef du Vin to predict how well a bottle may age helping them decide which wines are worth keeping and when their ideal drinking age will be. Winemakers are even using the special alloy to assist them in making decisions throughout the fermentation process.
