subject: What Is a Sourdough Starter? [print this page] Check on your starter time from time, it should have a sour smell that resembles beer. Before you want to bake your sourdough bread put the starter in a jar, just make sure that it isn't air-tight, the wild yeast in the starter is a living organism and needs air to live. Store it in a cool and dark place; don't store it in warm places as heat can kill the yeast. Avoid using metallic containers as they can affect the taste of your bread later on.
