A patented metal alloy, the Clef du Vin is a calibrated instrument that reveals a wine's aging potential.

It works effectively on all types of wines: whites, sparkling, rose, reds and naturally sweet wines.

Each second the alloy disk is in contact with the wine will mimic one year's aging: the effect is cumulative and irreversible.

Perfect for wine collectors, oenophiles and those who just enjoy wine.
