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.
The bad news is that age worthy wine isnât particularly common. In fact most wine (Iâd even speculate as much as 99% of wine, see trends in wine) is meant to be drank young. Only a tiny fraction of wine is actually designed to stand up to and improve with aging. 99% of all wine should not be cellared. For the most part wineries take the guess work out of aging by handling it during production. This gives you a ready-to-drink product that doesnât require any additional time in the cellar.
