Hulled Barley (sometimes called Dehulled Barley)
Hulled barley is covered barley that has been minimally processed to remove only the tough inedible outer hull. It's challenging to remove the hull carefully so that some of the bran is not lost – but that's what must be done for covered barley to be considered whole grain. (see Pearl Barley, below)
Hulless Barley
This type of barley has an outer hull that's so loosely attached to the kernel that it generally falls off during harvesting. This cuts down on processing and ensures that all of the bran and germ are retained.
