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.
By contrast, fortified wines such as port or sherry can last several weeks or more; the higher the alcohol content, the longer the life of the wine. Wine lifespan varies depending on the acidity of the wine; a high-acidity wine such as a Riesling or Sauvignon Blanc will survive a little longer than a lower-acidity wine such as a Pinot Grigio.
