Brown rice isn't milled as much as white, so it retains the bran and germ. That makes brown rice more fiber-rich, nutritious, and chewy. Unfortunately, it doesn't perform as well as white rice in many recipes. Long grains of brown rice aren't as fluffy and tender, and short grains aren't as sticky. Brown rice also takes about twice as long to cook and has a much shorter shelf life (because of the oil in the germ). Keep it in a cool, dark place for not more than three months. Refrigeration can extend shelf life.
