Peugeot Clef du Vin Metal Wine Ageing

A patented French‑made wine accessory designed to help you quickly assess a wine’s keepability and ageing potential. Simply dip the metal disk into a glass of wine — each second of contact mimics about one year of bottle ageing — allowing you to taste how the wine might develop over time or enjoy a young wine sooner. Effective on all types of wine (red, white, rosé, sparkling, sweet), this elegant stainless‑steel tool blends oenological insight with classic Peugeot craftsmanship.
