A cladogram is a stylized diagram that looks like a series of Y's or forks in a road. At each branch, or Y junction, novel characters of evolutionary origin are used to separate off one group from the rest. Cladograms can be constructed for any group of organisms.
I checked with the bubbly brain on staff, Bruce Sanderson (who reviews Champagne for Wine Spectator), and he says, Champagne can age well. High acidity and carbon dioxide act as preservatives as it ages in the bottle prior to disgorgement. After disgorgement, Champagne will develop like a still wine. If the quality is high (i.e., an excellent vintage-dated bubbly) and it is well stored, Champagne is capable of long aging.
Sounds like this is the non-vintage, yellow label so baed on this assumption, it is a Champagne that is not produced to age...it is meant to be consumed upon release, enjoying the youthful fruit qualities of the wine. That being said a year or two shouldn't hurt it provided storage conditions are good. Vintage Champagne are created to age and will become more complex through the aging process. In regards to the non-vintage you don't need to save it for a special occasion....Champagne is actually one of the most flexible food wines!
