Peugeot Clef du Vin Wine Ageing Tool

A unique tool that ages wine one year after one second of contact, rapidly softening tannins and acids so a wine's natural flavours and aromas are more pronounced. 

---DETAILS---

Peugeot’s Clef du Vin is a wine ageing tool that helps you decide, in an instant, the ageing potential of a bottle of wine. This patented tool, the result of a decade of research, is completely unique—one second of contact with the wine will age it one year, due to contact with an alloy that instantly reduces the oxygen content. This softens the tannins and acids to reveal a bottle of wine's most authentic flavours. To use it, pour a glass of wine, taste it, and dip the Clef du Vin in the glass for a second, then taste the wine again. If, after several contacts, the wine still keeps its qualities, or improves, you will be certain the wine has very good ageing potential and is worth keeping. If a wine is too young, this tool also allows you to enjoy it without having to wait for it to age. But the Clef du Vin is not just for experts and collectors. Novices can use it to refine their understanding by pouring two glasses of the same wine, side by side, and using the clef in one of the glasses to taste the precise differences.
