Ping Roy Basan at alt.bread.recipes or rec.food.sourdough on this. About a
year ago he was discussing this and the causes and I just don't remember
what it was about. I think it had something to do with low ash content in
flour that was used for sourdough, but I'm really not sure. I don't think
it's a case of going bad as in making you sick, but rather a degradation of
the dough.
