Sour Dough Starter Green?!

Sour Dough Starter Green?!


I decided to try Kevin Dunden's sour dough starter. The first day was fine, looked and smelled good. I used spring water and US bread flour.

This evening I see some green on the top of the starter and it doesn't smell very good. I'm wondering if it is mold?

Should I be concerned? Do I need to throw it out or can I remove the top layer and hope the green doesn't return?

Thanks for any advice.

I can't see green mold forming overnight. But maybe some green fibers from a towel crept in there. I would spoon it out and see if it comes back. If so, start over and be sure your container is very clean and gas no soap residue. 

Note, the hooch may be greenish gray. That is normal. Post a pic.

Hi David,

Thanks for your reply. I realized I should have snapped a picture. I went to do so this morning, but the mixture is bubbling nicely, smells really good and the traces of green (2 about 1 inch long each) are gone...into the bubbles I presume.

Hopefully it is just as you suggest.

:D Susan
