Hey guys... My sourdough starter crapped out! It is deader than a door knob. Not sure what happened to it, fed it , made some bread, fed it again a few days later, and now no sign of life. Tried for a week, everything I can think of... So it got a proper burial tonight. Sad part is, it was so well established, and full of flavor, to get a new one back to that level will take months/years. Crappy... Any thoughts why it may have failed. And any tips for making a new one?
