My whole wheat sourdough
starter, that I've had for 1
year, has a new odor...I feed
it every weekly with fresh
home stone ground wheat flour.
I ferment it at about 90º. Two
feedings ago, I noticed a
change in it's odor. I also
notice a change in the way it
bubbles up in the refrigerator
between feedings...which is;
before, sometimes there would
be a darker liquid that formed
on the top of the bubbly
starter. NOW, I notice there
is a clearer liquid that forms
at the bottom of the bubbly
starter and the odor is a bit
offensive to me...smells bad
to me but the bubbles indicate
that's it's feeding happily.
Last week when I made
sourdough pancakes the kitchen
had a new odor afterwards
also. What's up with this? Help!

Thanks in advance,
