One of my favorite foods is San Francisco Sourdough bread. Boudin bakery lays claim to the original sourdough bread and still has the mother dough cultivated from a goldminer’s sourdough starter. 

More history on San Francisco sourdough bread.

I have read that the flavor of this sourdough bread has to do with the bacteria that develops as part of the fermentation process and wild yeast in the air that helps create the sourdough starter.  All I know is San Francisco does have some of the best bread and I have not found bread here is Southern California that is as good. I have looked at the ingredients on some bread sold in stores and some just have flavoring and not the sourdough culture.
