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.
France- The legal drinking and purchase age is 16 for beer and wine and 18 for spirits. Anyone under the age of 16 can drink alcohol as long as the child is with the parent/guardian. Italy- It is legal for 14-18 year olds to drink if the alcohol is provided by a parent or legal guardian.
