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.
For wines above thirty dollars, a majority of these too should be consumed within five years. Only wines that are considered âpremiumâ truly benefit from aging and, at that point, there are all sorts of specific rules (depending on the type of wine you want to age) that dictate how long you should age it and when the wine will be absolutely perfect.
