My dad bought a restaurant a couple of years ago and there were a few bottles of beer sitting in his cooler from the previous owner. One is a Breckenridge Christmas ale from 1996 in a 1l fliptop bottle. It's hand numbered. Another is an amber ale from Coors Field from 1995 in the same type of bottle. There are also two bottles of belgium dobble in corked champagne bottles. I'm pretty positive that the amber will be horrible. The Christmas ale might be bad, too. The dobbles intrigue me. They don't have dates on them so they might still be good. Do old, unopened beer bottles have any collectability? Are they even safe to try? I'm leary but I'm also intrigued. So what would you do?
