The Rib Roast is cut from the Rib section, which comprises ribs six through twelve of the animal. They are a cornerstone of weddings, family gatherings, and carving stations across the country. And while all Rib Roasts are colloquially referred to as "Prime Rib," not all are USDA rated Prime. We, of course, make sure that each and every Rib Roast we sell is USDA rated Prime. This Rib Roast is wet aged for 25 days with the bone left in, for a rich, delicious flavor profile.
