The origin of San Francisco sourdough goes back to the Californian gold Rush of 1849. Some of the french immigrants who came seeking their fortune started to make bread.

With their long experience working with sourdoughs in France, but under the influence of local airborne micro organisms, they made a sponge dough whic became the San Francisco Sourdough bread.

It is a white bread characterized by a  pronounced sourness so much so that the dominant strain of lactobacillus in sourdough started was named Lactobacillus Sanfraciscensis
