I was wondering if anybody can help me, as ive mentioned above i have a 100 % rye flour starter @ 100% hydration, which has been going for about a week. It has started doubling in about 6 hours, but constantly smells like acetone, even when a few hours in. Im in the uk, and its not really to hot here at the moment, so im pretty sure its not fermenting to quickly due to temp. Sorry in advance for grammar/ and or spelling mistakes in advance. just wanted to get this post out there ! Thankyou, craig.
