What is the difference between hulled and pearled barley?
Hulled barley loses the tough inedible hull but keeps most bran; pearled barley is polished further and is not classified as a whole grain.

The short answer
Hulled or hull-less barley generally retains the bran, germ and endosperm that define a whole grain. Pearling removes some or all of the bran, shortens cooking time and changes texture and fiber context. Both still contain gluten, and product-specific nutrition should come from the label or a matching food-composition record.
