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 purchase of beer and wine, you need to be at least 16 years old, and for purchasing harder liquor with more alcohol content, one should be more than 18 years of age. In Italy also, as well as in other parts of the continent, rules are almost similar.
