San Francisco starter
Ok, I do hope this hasn't already been asked, but I expect it might...
However, the question is this. If you have a starter, could be from SF, could be from Timbucktu, at what point after refreshment does it no longer have the right to be called, 'SF sourdough' or 'Timbucktu sourdough' starter?
If I keep adding a floour and water from anohter place on the planet, does that corrupt the original?
