I pitched mine with Nottingham on Friday, since that was all the "spare" yeast I had, and I didnt really feel like driving 20 miles to the LHBS just for a yeast run. So far it has been slow to start. There is definitely some activity, the lid on the bucket kind swells after 2-3 hours, but there has not been any airlock activity. The airlock is floting, so I have a feeling that it is bubbling, just at a significantly slow rate. It hasnt been very long, so I am going to stick it out and see what happens. At what point should I consider repitching, or is there anything I can do to help it along? I am kind of thinking maybe make up a warm sugar/water solution, take a sample from the batch, and create a second "starter" assuming that the sample has enough viable yeast, of course. Good learning experience, I suppose.
