Can I save a starter that has begun to smell odd?
I have had a starter that i have been happily maintaining for the last six months or so that I keep fed with half whole wheat and half rye flour and at 100% hydration. I left it a little longer than usual between feedings this last time and I feel like it has developed an odd smell; musty or bitter. Any idea what may have happened? Can I restore my starter to former glory? It's also expanding faster than usual which makes me suspect that it has been taken over by something unsavoury, so to speak.
