Giving your friends samples of interesting things you've found over the years is really fun. And sometimes it's a bit like having a nice suit that you put on for special occasions. My collection grew to the point I realized I could never drink it all, so I started giving it away, and now I only collect something new when I've emptied something else. It's fun to go back and try things. "Ooh, I haven't had the Absinthe in a while!"
