just opened a 1968 bottle of jim beam in a china bottle...bought at an antique store for 22.00.i dont really care for beam...but the color and aroma are alot different than a new bottle.really dark caramel color...nice consistancy,and a charcoal type taste.this was a sealed bottle i had to force the top off.so if it is in a completely dark environment...yes...it does get better with age...depending on light.
