Help a bourbon beginner out. I have roughly 15 bottles open of various shelves. Now every bottle doesnt amaze me first pour, some are amazing from the seal cracking, but ALL bottles even those that are just boring at first seem to become intruiging and better every pour over the next month. Maybe Im just experiencing developing my nosing and tastes but it seems like a few weeks after cracking the seal the bourbon opens up. Several recent bottles I paid attention and saw tiny bubbles rising after breaking the seal that continue after corking for awhile, so inform me of the bottling process and why they get better. I know it happens just not why.
