organic grape starter

Jerry Hughes

Last summer I made to starters from organic grapes. I read about this in a book by Nancy silvermann.

the first was made from Spanish grapes:
 about twp cups of ( unwashed grapes, stems and all)
a cup or two of water ( not tap, no chlorine)
and high gluten white bread flour ( I use King Arthur)
put in a blender un till all grape stuff is thouroughly intergrated.
It takes about 2 weeks of feeding 50% water and 50% flour to get the starter active- but oh! my what a flavour

My question is: recently one of my starters has developed a MOLD - I take it that I have been invaded with a sourdough virus- should I throw this out? start over or scrape off the mold? any ideas

I would start over again. A good sourdough culture is resilliant to foreign bacteria or molds unless it is left unattended for more than several months. Start the sourdough with a chease-cloth and once it is established, keep it in a sealed container in the refridge.  Good luck, Adam

We used grapes and strawberries to obtain our cultures for mold in microbiology, because a variety of molds are so prevalent on the skins. Are you still adding any grapes to your culture? If so, I would discontinue that because you are just reinforcing the mold in your culture. Otherwise I am with Boris, you should be able to keep your culture. Just scrape it off, use a clean jar, put some of your culture in the jar and refresh it. Boris that rye mold is pretty interesting...wonder what species it is? Terri

since finding mold- I have since scraped off the mold, replenish with flour and water every time I use. almost daily now. The breads are great- i guess I need to get the camera out- I am looking at doing some rye breads- tothis point mostly French type breads and some whole wheats. Jerry
