Kodiak is correct, thats probably the best way for properly aging, with an occasional opening of the bottle to let it breathe. For smaller quantities though - stick it in your pocket all day, the heat and motion works wonders. Setting the bottle on top of a cable box works too. I've found low consistent heat works the fastest with the least effort. Just aging alone doesn't do much, I have unopened bottles six months old that are still the same color as when they arrived, after a week of heat and agitation, they turn practically black.
