I was just looking at the new Beer Connoisseur magazine and noticed this in the cellaring article. I'd never heard of the humidity in the bottle or the cork causing off tastes being the reason you shouldn't lay down corked beers . Do people agree with this? Or is this meaning for more short term aging? "Research actually indicates that corked beers usually do best when stored upright. The humidity in the airspace of the bottle generally works well in keeping the cork moist and tight for many years, and long-term contact of beer with the cork may sometimes lead to off-flavors. The majority of corked beers come with a layer of yeast sediment in the bottom of the bottle, so keeping the bottle upright ensures that the sediment remains at the based – making pouring the beer without disturbing the yeast layer a bit easier. Perhaps storing a few bottles of a corked beer upright and comparing these to ones stored for an equal amount of time might constitute a worthy experiment. In any case, beers with bottle caps should always be stored in vertical position."
