What is Sourdough?

Sourdough is a traditional method of capturing wild yeast and lactic acid bacteria which exist in the environment, floating thorugh the air.  The yeast feeds on the simple sugars contained in flour and along with the bacteria create gas which levens bread (i.e. causes the bread to rise).  The sourdough starters available on our website are traditional sourdough cultures from around the world baring the yeast and bacteria from their respective geographic regions.
