does brandy,in a unopen bottle age well

The theory that an unopened bottle of whiskey or
brandy will improve with age is false. Spirits aged in a barrel
will change considerably over the years, however, the bottle
of spirit that has been saved for a special occasion will look,
taste and smell exactly the same as the day it was bottled.

Unlike many alcohols, brandy does not age in the bottle. Legally it
must age in barrels prior to bottling. Great care is taken with the
aging process with respect to what types of barrels may be used and
how long it must be aged. Only certain types of French oak may be used
for the barrels: Limousin, Allier, Troncais and Nevers. Cognac
producers pride themselves on the craftsmanship of their barrels, and
many retain their own craftsmen to ensure that their barrels are free
from any synthetic materials, such as nails or glue, which interfere
with the aging process and, ultimately, the flavor.
