Difference between graham and whole wheat flour?

Graham flour is a type of whole wheat flour made from hard wheat that has been coarsely ground, retaining the bran, germ, and endosperm, which gives it a slightly sweet, nutty flavor. Whole wheat flour, on the other hand, is milled from the entire wheat kernel but is typically ground more finely. While both flours contain the same nutritious components, graham flour is often used in specific recipes like graham crackers, while whole wheat flour is more versatile for general baking.
