White flour is generally made from soft wheat, while spelt is similar to farro and has an earthier taste.  Spelt flour contains less gluten than wheat flour, making it simpler to digest for persons with celiac disease or gluten sensitivity. The endosperm of the wheat kernel is used to make white flour. It is a type of flour that has been milled to remove the bran and the germ. This flour is usually bleached, which gives it a whiter color.  On the other hand, Spelled flour is made from an ancient grain that is related to wheat. It is high in protein and has a nutty flavor.
