I was reading in the latest BYO that a guy was using tweezers to dispense 2-3 granules if dried yeast into bottles for beer that had been aged for longer periods of time, as the yeast has a tendency to no longer be viable after long aging. I’ve also read of people using either re-hydrated yeast or liquid, such as Wyeast of WLP and using a medicine dropper or pipette and administering 1 drop of liquid in the bottle.
Has anyone used either of these methods? I’m aging an imperial stout in secondary, and was thinking about doing this.
Any suggestions?
Thanks
