Clef Du Vin Pocket Model Professional Collection

Designed by a French winemaker, the Clef du Vin is a revolutionary new tool to help you assess the ageing potential of your wine.
Immersing the Clef in a sample of wine for just one second simulates the effect of 1 year’s ageing, 2 seconds for 2 years and so on. So now you can judge whether a wine is worth laying down and, if it is, when it is likely to reach its peak. It also makes young wines drink better now – plus it’s fun to use and try on any wine.
The Clef is totally inert. It does not contaminate the wine in any way. It is simply a catalyst to promote the normal ageing process that takes place naturally.

Comes in a mock leather box with full instructions.
