Frothy white at bottom of starter
I recently received a whole wheat starter from a friend and have been searching everywhere for help on maintaining it. I last fed it Monday evening, used part of it to bake a decent whole wheat bread on Tuesday leaving the rest out, and just popped it in the fridge today (Wednesday). What I'm worried about is after the bubbling died down a little it split into two layers. The top layer is the normal wheat color w/ a lot of bubbles. At the bottom however is a frothy white mixture the texture of whipped cream and the entire thing reeks of alcohol. Is the white mixture something that should be there or is it possibly something that could make my family sick? I'm extremely new at this so for all I know it could be yeast.
