Obviously one can harvest yeast from the fermenter, but has anyone ever harvested the yeast out of a beer bottle? I see no reason why it can't be done. Sure there is not as many yeasties in a bottle vs a carboy or the like, but with a little love they should be able to multiply to large enough quantities for the desired purpose.
It seems easier to me than washing your yeast. Thoughts?
