“White” flour is usually made by refining (whole) “red” wheat. The process strips away the germ and the reddish–colored bran—as well as most of the grain’s minerals and fiber. If you prefer the taste and look of “refined” flour, good news: many brands now offer loaves made from a milder–tasting white whole–wheat flour. Look for products labeled “white whole–wheat” or check the ingredients list.
