San Francisco Sourdough Culture: King Arthur Bread Flour vs Milled Whole Wheat
I got some of the San Francisco sourdough culture from http://www.sourdo.com/. I decided to make two different starters -- one that was fed nothing but King Arthur Bread Flour, the other fed nothing but home-milled hard red and hard white wheat. Both produced extremely active cultures within 4 days of 12-hour feedings. I used the basic sourdough bread recipe from BBA, using KA Bread Flour for one, and an 85% extraction sifting of hard red wheat (13%) for the second.
