I have a started that is about 5 years old. I use the Nancy sliverton starter. I do everything by weight so when my scale broke I did not make any bread. The starter had been doremant in the refrigerator for several months waiting for the new scale. I have now been feeding it again for two days, three times a day. The smell is just not the same. It is more strongly sweet. Not the mellow yeasty sour smell. Has it turned? Can I save it? I will be so sad if I have to start over! thanks for any help you can give.
