I don't have a lot, and what I've got is open. I buy to drink, and looking at a bottle on the shelf that I can't taste would drive me crazy. I'm halfway through my Hirsch 16 gold foil (I've never tried the wax, and at this point figure I never will) and almost done with my pappy 20. They're the best bourbons in my cabinet and I'm worried about what I'm to do when they're gone.
That said, after opening my bottle of Anchor Hotaling's I bought two more bottles and packed them away for my kids. It's not bourbon, but I enjoyed it and saw them as limited enough to have novelty appeal when they're old enough to care.
On a budget it's hard enough to get enough for sipping. Collecting at this point in my life is impossible. I enjoy reading about people's finds though.
