It's bottle-conditioned, and when I saw it at my beer store, I thought this would be the perfect chance to try harvesting yeast for the first time. I have successfully made starters in the past. But my starter isn't doing much. It seems pretty dead. There was definitely some "stuff" in the bottom of the bottle, but I'm getting virtually no activity. I wonder if the 100 days of conditioning time, plus a transoceanic voyage, plus who knows how long sitting, might have killed it?
