Sourdough Culture Contamination Concern
« on: February 22, 2012, 08:56:13 AM »
I received the dormant Italian starters from Sourdo.com 36 hours ago...  I have attached two pics below of the starters after 24 and 36 hours...  The do not look or smell as I would have imagined...

> the first pic is of the starters after 24 hours of proofing in a box @ 90 degrees

> the second pic is of the starters after the exchange of 1/2 the starter with 50:50 fresh flour and water and another 12 hours at 70 degrees

i saw very vigorous action after only a few hours in the proofing box, which I didn't think was normal... And I'm concerned about all this hooch...

Any advice would be greatly appreciated!!!

Thanks,

Dan

Dan;
Most bacterial starters take a bit more than just a few hours before they show any real leavening power, but possibly the starter that you got is not a bacterial starter, but rather a yeast (wild yeast) starter? What does the manufacturer say about how long it should take before you begin to see the development of leavening gas?

These are the Ischia and Camadoli starters from Ed Wood at Sourdo.com

He states in his instructions that the activity should be limited in the first 24 hours...

It seems bacterial contamination is common with these starters.  They cause the early funky activity.  Lots of discussions on how to deal with it and what causes it. Just do a bit more reading for all the detail.  I had the same problem and it was discussed here:

The general consensus seems to be to just keep with the program (wasting and feeding), though I went ahead and washed mine.  Washing is discussed in the information you received with the starters.  Eventually, the "good bugs" will win the day.  Don't give up.
