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.
Agreed, a properly stored corked bottle of wine will last for several years. Some varieties are best within the first few years, they tend to be the cheaper wines. There aren't many wines that benefit from aging for more than 5 years. Among those that can age that long are the very tannic wines, like Cabernet Sauvignon.
