The Clef du Vin website doesn’t tell what metals are in their product. They say only, “What does the alloy contain? The answer forms the basis of four international patents.” However, I have found a number of websites that recommend using copper or silver to correct wines that are “reduced” and have sulfur-derived off-smells (e.g., burnt rubber; see http://www.wineloverspage.com/wineadvisor1/tswa060120.phtml). Tom Ciocco ... talks about reduced wines (http://terroir.winelibrary.com/2007/02/12/reduction-augment-your-understanding/), but he doesn’t mention copper or silver.

The unique and exceptional Clef du Vin™ is essentially a measuring instrument that will immediately tell you if your wines are suitable for laying down, and ... revealing their ageing potential. In a controlled way, it will gradually modify the organoleptic qualities of the wine (taste, smell, flavours and bouquet). The Clef du Vin has been carefully calibrated so that one second of contact in a glass of 10 cl. (or a bottle of 75 cl. using the corresponding key) will display the potential lay down time of one year. Effective on all types of wine (red, rosé, white, dry, mellow, sweet, fortified or sparkling), the Clef du Vin is in fact an informative measuring instrument.

Clef du Vin lets you assess the precise ageability of any wine. When dipped into wine, a patented metal alloy located on the tip of Clef du Vin replicates the key aspects of the natural aging process. The wine's life will quickly mature along the natural aging curve towards total oxidation. Discover in seconds where your perfect taste is. Harsh, young vintages will become softer and more subtle. Effective only on wines with aging potential. Now you’ll know the ideal moment to enjoy every wine at its peak.

Similarly, the advantages for professional people are considerable: - The Clef du Vin will provide the oenologist with information about the oxidation-reduction of his/ her wine. Having a better understanding of this complexe process is invaluable when making decisions during the production and maturation processes. - The Clef du Vin is an aid to sales on a large scale. - The Clef du Vin optimises the selection and purchasing processes. - It’s ludic approach increases the pleasure of drinking... increasing the sales of wines at a restaurant for instance.
