1. Literally, to put and store inside a bottle, as a liquid. I've started bottling away some of my own homemade beer, since it's actually cheaper than buying it from a store. A lot of people began bottling water away during the Y2K panic.

2. To hold onto something inside and keep it from being expressed or released openly, especially thoughts or emotions. If you bottle your anger away, it will only grow worse, and soon, you won't be able to contain it. Please talk to me, don't bottle away your emotions like that!
