During the XIXth century and uptil the 30s, vintages were an important part of the cognac trade.  It is still possible to find old vintages coming from the House of Prunier in certain auction sales.In 1986 we decided to renew with this tradition and as we had cognacs which had been aged in cellars controlled by the Excise Authorities, we were able to prove the age of these cognacs.So 20 year old is a revival from the past respecting the old traditions.  Aged in damp cellars we let the cognac reduce naturally their alcoholic strength.  When you leave nature to do its work you are always rewarded.
