I am speaking for me...my experience; and, yes...I am aware that there are exceptions. I am aware that someone may say that a beer that I've found to be over the hill "was the best bottle of beer he/she ever had!" I get it. This is my opinion based on my experience. I did not intentionally "age" several of the small bottles that I tasted this afternoon. I have a deep cellar and I finally took 48 small bottles out to taste - bottles that I've just not gotten around to or simply were never opened as we opened larger bottles or rarer bottles at beer tastings. So, today I'm going through about 48 small bottles from about 2009 to 2011 and of all different styles and breweries. The only constant is that they are all small bottles - 12 oz. Basic conclusion: I have ruined a lot of beer! My mistake; my error; my bad. Almost all of these bottles, from the strong ales, to the wild ales, to the fruit ales to the barleywines, porters and stouts - all of them - have NOT improved. Almost all of them, candidly, are just over the hill and not "what they were." (And, note: All of these were in a 56 degree cellar for the past year to 3 years/4 years. They were stored at optimum condition, other than being in a refrigerator/cooler which, in my opinion and based on how they tasted, likely would not have helped most of them.) My conclusion, for myself, is that I'm going to try to keep a lower number of bottles in my cellar. My conclusion is also that I am not going to store/age small bottles at all! Large bottles, like wine, tend to oxidize and age slower (and I'm probably ruining a lot of those too). However, the smaller bottles, to a bottle, have just not stood up to any meaningful age whatsoever. Just about everything over a year old has not improved and does not taste as good as when fresh. Just my opinion; just my experience. I'm sure that I'll end up keeping small bottles for a while unintentionally just because I (like most of us) buy/obtain a lot of beer and I can't drink or taste it all. However, I'm going to strive to age only those bottles that I'm sure can take it or that I really want to watch change. I hope at least some of you benefit from my experience and mistake. Hey, if nothing else I'm re-cycling all the glass!
