You guys are right. Scotch may not mature over time in a unopened glass bottle but it does mellow, which is very nice IMO. Pretty sure its the same with burbon. Oh, and you could try one of two things with that partially opened bottle of scotch. Keep pouring the remainder into smaller bottles or put glass marbles into the bottle to raise the fluid level. The whole point is to keep the amount of air in the bottle to a minimum.
