I recently had a eruption from the FV. I had a blow off tube into a 1g carboy 1/2 full of a solution of Star SAN. Once the fermentation calmed down I removed the tube and bottle to clean out and reinstall. I did notice a large amount of what appeared to be yeast in the bottom of the container. This did get me thinking. Assuming this is the same as top cropping, if I using sterilised water in the bottle rather than Star SAN, could I reuse this yeast I’ve collected?
