Sous Vide Standing Rib Of Beef- The Perfect Christmas Centerpiece

Bite of Prime Rib

Is your Holiday centerpiece a Standing Rib Roast or a Prime Rib?

Meat labeling can be a culinary quagmire even for the most knowledgeable cook. You have myriad of ways to cut beef with differing cuts associated with different countries that find their way into cookbooks, magazines, and groceries not to mention regional variations right here in our own country. That’s just for cutting, and then there are some labeling programs for beef are governed by the USDA Agricultural Marketing Service under a user-fee system for ‘voluntary’ claims. Others are governed by the USDA Food Safety and Inspection Service as mandatory requirements based on food safety considerations. In some rare cases, the claims are even governed by the FDA - whew!

Today, let’s focus on a Standing Rib Roast or what many of you understand as Prime Rib. “Standing" means that because the bones are included in the roast, the roast can stand by itself. A rib roast with the bones removed is commonly referred to as a rolled rib roast.

Back in the day, Prime Rib used to refer to a “prime grade” standing rib roast, but these days all rib roasts (and some rib steaks) are called “prime rib” regardless of the USDA grade it received. So please keep in mind although the actual cut is called the PRIME Rib, it will come in the same grade levels as other cuts, namely Prime, Choice, Select, among others.

Speaking of grades, the U.S. Prime Grade is the highest grade of beef with the most fat marbling. This meat is very tender and only accounts for about 2.9% of all graded beef. U.S. Prime is usually reserved for high end dining establishments or high end groceries. Because this beef has such a high level of fat marbling, Chances are you won’t find true Prime Grade Meat in your local grocery but if you do, be prepared, it ain’t cheap!

Keep in mind though, that the USDA meat grading system is optional (and can be expensive) so not all meat is graded and it’s up to the producer to decide. Take grass-fed beef a very popular tasty style usually isn’t graded for the sole fact that grass fed beef is very, very lean and consequently wouldn’t get a “high” rating due to the nature of the beef so chances are you won’t find any sort of USDA grading but it doesn’t mean it’s not good or high quality beef.
