The Rib Roast is cut from the Rib section, which comprises ribs six through twelve of the animal. This popular cut is 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. We dry age our Rib Roasts for 40 days, and remove the bones, so you can easily cook up this flavorful and tender cut.
