I have been aging a few beers for several years, 2005 Darklord, 2007 Worldwide Stot, several years of BCS, a bunch of different barleywines (Bigfoot, Olde School, Old Foghorn, Old Horizontal, etc). My question is, how long is too long to leave it in the cellar (my cellar is a cabinet next to the foundation in the basement)? I've found BCS is great after 3 years, the Darklord was amazing at 6, a WWW was bad after 8 years. Is there an optimal age by style? Thanks all!
