SRS..my rule is, it don't get on the shelf unless I drink it myself. I once made a half-hearted attempt to apply a rating system, but it would have been mostly to decide what to buy again, and too many disappear for it to make much difference.
   The very sight of the bottle often reminds me, and I now have a general idea of what is available. (and I can't afford to RE-try everything, anyway, as the collection is now 30 years old) I add a few new items every year...mostly of stuff that very thoughtful folks bring me from England, Wales, Canada, ...and occasional items from local breweries.

also-- I drink 'em at a far slower pace than I used to! I got some wonderful stuff for Xmas, and am still working on those!
