The Peugeot Wine Ageing Tool is a measuring device that can tell you instantly the keepability and ageing potential of a wine, of any type. The Peugeot Wine ageing Tool is the fruit of 10 years of research and has been patented. Pour yourself a glass of wine, taste it and remember your feelings. Dip the Wine ageing Tool disk in the wine and taste again. Every second of contact with the wine corresponds to a year of ageing. If, after several contacts, the wine still keeps its qualities, or if indeed it improves, it has very good ageing potential and is worth keeping. If the wine loses its precious qualities after just one or two seconds of contact, it has no keepability potential. You can repeat this operation, second after second, until there are clear signs of decline in the wine. This allows you to determine the ageing potential and to decide whether to keep the wine. The Wine ageing Tool can also allow you to enjoy a wine that is too young, without having to wait.
