I am just going to touch on this subject today but do plan on coming back to it in the future. I have recently started opening up my beer cellar, which consists mostly of barley wines and imperial stouts. So far, in the past year or so, I have tried about 40 vintage beers. The only one I have found a noticeable flaw in was an 09 Stone Old Guardian in February 2012. This was in no way Stone’s fault and likely due to poor storage (which could be a variety of things, the beer may have had a rough trip back from Florida, the closet was certainly not at the ideal temperature and from what I have heard, sometimes this stuff just happens). Either way, the beer tasted a lot like cardboard which would make sense as the beer was fairly light in color and probably developed a significant amount of aldehyde. Fortunately, everything other vintage beer I have tried turned out much as I suspected. I noticed a particularly large difference between years in Lagunitas products such as Old Gnarlywine. These aged barley wines were good but in every case including a side by side of Firestone Walker’s Abacus and Sucaba, I preferred the fresh version. Perhaps, I am just not a huge fan of the sherry like flavors that tend to develop with them. With that said, I have had some phenomenal aged imperial stouts such as Bell’s Expedition Stout that blew me away after sitting a few years. I have also had some extremely pleasant experiences with aged sour browns such a four year old New Belgium La Folie. Ultimately, I am leaning towards drinking beers fresh, but vintage beers can be a nice treat. I have also heard that Brauerei Schloss Eggenberg’s Samichlaus has legendary aging capabilities. Here is a slightly more in depth look at some of the basic chemical processes that tend to go with aging of beer http://www.professorbeer.com/articles/oxidative_staling_beer.html
Now that you know what to expect, experiment and enjoy! Please add any thoughts and I do plan on returning to this subject as I learn more!
