I selected 20-40. I almost always drink imperial stouts and the majority of them are bottled. That said, it is getting closer. My avatar picture is part of what I had available (all imperial stouts) for my annual Beer Gathering three years ago and the vast majority is bottles. A quick survey of the distinct stouts I have collected for the next one shows 38 bottles to 21 cans, definitely a tightening ratio. Maybe a good thing? I have never had a complaint about Ten FIDY. All of that said, it has no impact on my decision.
