Ageing potential of champagne: champagne is one of the greatest
wines for ageing (vins de garde). Certain champagnes can age and improve for 20
years and more, on condition that they are aged on laths, to settle the
inactive yeasts (bottle fermentation yeasts), before disgorgement. Therefore,
the producer decides the ageing duration of the champagne. The producer will decide to disgorge and then sell his champagne when
he believes it has reached optimum maturity.
