i've read on here quite a bit about people culturing yeast out of a bottle of coopers sparkling ale. and why not, its free when you buy the beer, and its a pretty darn good beer. last night i had one of their 2002 extra strong vintage ale, and i was pretty impressed by it. would there be any drawbavcks to using a yeast thats been bottled for two years? is there a "deadline" on how old a bottle would have viable yeast?
