Peugeot wine key

The Peugeot Wine Key is a revolutionary measuring tool that allows you to instantly assess the aging capacity and potential of a wine, whatever its type.

The result of 10 years of research and patented, this unique accessory works simply: pour yourself a glass of wine, taste it and memorize your impressions. Then, dip the Clef du Vin tablet in the wine and taste again. Each second of contact with the wine is equivalent to one year of aging. If, after several immersions, the wine retains or improves its qualities, this indicates that it has aging potential. On the other hand, if the wine loses its qualities after only one or two seconds, it has no aging potential. You can repeat the experiment second by second until you perceive signs of decline, which will allow you to determine its aging capacity.

La Clef du Vin is also ideal for enjoying a wine that is still too young, without having to wait.
