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.
If the wine is kept at in an average household room, the temperature will cause the wine to mature quickly and the varying temperature will cause it to age even faster. The ideal temperature for wine is typically between 39 and 65 degrees, white or red. A fair temperature to keep both would be right around 55 degrees. If you chill your white wine too much, you won't be able to completely taste all the wine since its flavors will be hidden by the chill.
