I've got a few bottles of (non-BA) BORIS, and my gut feeling is to drink 'em up sooner than later. I really liked the one I tried, but it doesn't seem to have any serious harsh flavors that might need to mellow. Seemed to me like a great, sweet, nicely balanced beer as is. BUT: I'm new to this cellaring game, so I was curious to hear what experience / opinions folks have. Cheers! PS I've got a couple DORIS as well, though I haven't tried that one yet.
