After you become familiar with making sourdough bread, you can use our same recipe and replace some of the Heritage White Flour or Heritage Bread Blend Flour with Heritage Whole Wheat Flour to make whole wheat sourdough bread. When you blend your Heritage Whole Wheat Flour with the Heritage White Flour, you will get the rise of the White Flour and the flavor and nutrition of the Whole Wheat. Try starting with 20% Whole Wheat and 80% White. You can then slowly adjust your percentage each time you make a loaf until you reach your desired loaf.
