Wine Aging Tool
Available at: Amazon.com
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 ageing: the effect is cumulative and irreversible. Perfect for wine collectors, oenophiles and those who just enjoy wine. 2 year warranty from the date of purchase.
