The Clef du Vin allows the user to replicate the key elements of the wine oxidation and aging process at an accelerated rate of approximately one year per second of use. Simply place the tip of the Clef du Vin into a wine glass (included Standard or Pocket Models) or wine bottle (included bottle Model) for intervals of 1-2 seconds each. The wine will quickly mature through the natural aging curve and approach total oxidation. Experience the perfect taste in seconds! Effective only in wines with agingin potential, the Clef du Vin can allow the taste of harsh, young vintages to become softer and more subtle.
