Bovines have been a part of human life for thousands of years. The ancestors of cattle and bison, named aurochs, can be seen on paintings of cave walls in Europe. We have used bovines for centuries to pull plows, for their hides, for milk and cheese, and their flesh for food.
It is a safe bet that it didn’t take early humans long to determine that different muscles in the carcass had different characteristics. Some were tender, some tough, some juicy, some fatty, some rich in flavor, some bland.
Nowadays most steers and heifers live on farms eating grass and hay until they are about 15 months of age. Then they are sold to huge feed lots where they stay for about four months and are fed grain, mostly a type of high calorie corn flake, and vitamins and medicines, often including antibiotics, for about four months. According to the Amazingibs.com beef scientist, Dr. Antonio Mata, “Bovines are like humans. When they consume a lot of calories they accumulate fat. First belly fat, then subcutaneous fat, then fat between the muscles, and finally intramuscular fat, which is marbling. The process is very inefficient but produces huge quantities of tasty beef at relatively low cost.”
On the other hand, the process has come under a great deal of criticism for a number of issues including arguments that the method is inhumane; that the antibiotics are not killing all the bacteria and the ones that survive are antibiotic resistant, and that means that humans can no longer rely on antibiotics when they get sick; that corn subsidies are making beef artificially cheap; that these large Concentrated Animal Feeding Operations (CAFOs) create a massive environmental hazard with unmanageable quantities of waste chief among them.
More and more cattle are being finished on farms on grass rather than grain, where the manure fertilizes the grass they eventually eat. The resulting meat is more expensive, often chewier, and tastes different, with a mineral character that I remember from my youth, before CAFOs.
Some disdain the taste, some love it. Mata says “grasses vary greatly. Alfalfa hay for example, can produce beef with plenty of marbling and superb flavor. Some of the best beef I’ve tasted has been fed primarily alfalfa. On the other hand, winter grasses produce beef with limited amount of marbling and depending on the grass, sometimes there is a fish-like flavor. Just like beef cuts, not all grasses are created equal, and most produce marginal tasting beef.”
I love the taste of both grass finished and corn finished meats. For more on the subject, read my article on beef grades. I hope to discuss these political and economic issues in depth in the future. Suffice it to say that I have read extensively on the subject, and I agree that corn subsidies, CAFOs, and antibiotic overuse are serious issues and there may be viable alternatives, but the impact of these other systems will certainly mean more expensive beef. Many of us can afford pricier beef, but many, especially those who depend on cheap ground beef, would face hardship or a major lifestyle change.
Beef primals & the cuts they contain
For centuries, animals were slaughtered and broken down by the town butcher and by restaurants close to where they were grown, and there was no label consistency from one butcher to the next. In 1865, immediately after the Civil War, the Union Stockyards in Chicago became a central distribution point for shipping live animals. In 1880 Gustavus Swift, a large meat processor, introduced a rail car that was well insulated, cooled by ice, and designed so that the shifting weight of hanging sides and quarters would not derail the car. The cold meat could stay fresh for days and be distributed to remote locations, like Miami, where they would be broken down by local butchers and restaurants. But the cuts and labels were still inconsistent.
This changed in War World II when the government standardized on “primal cuts” and corresponding nomenclature. There were seven primals: Chuck, rib, loin, round, short plate, shank and brisket, and flank. Some of these primal were further segmented into sub-primals: The loin is comprised of the short loin and the sirloin sub-primals.
In the 1960s a major change was pioneered by Iowa Beef Processors, called “boxed beef”. They removed many bones and a significant amount of fat at the slaughterhouse, then placed the cuts in sterile shrink wrapped plastic bags without oxygen, and packed them in boxes of the same cut. Without oxygen and chilled or frozen, the meat was safe from microbial spoilage and oxidation. Pork and other meat packers followed shortly.
Butchers long ago began excavating the carcass and named the cuts of meat, muscles, and groups of muscles they discovered. The jargon is confusing. There are more than 50 common cuts in the US, and some go by multiple names. Some have been confused for so long that nobody can say for sure what a Delmonico or London broil really are. To add to the confusion, the cuts and names are different around the world, even in English speaking countries. Today the North American Meat Processors book, The NAMP Meat Buyer’s Guide has become the standard by which butchers cut their meats so a chuck roll is the same coast to coast (see sidebar). It is the definitive argument ender.
In April 2013 The Beef Checkoff Program, the National Pork Board, and the United States Department of Agriculture (USDA) agreed to new labeling standards in an attempt to “make things easier on the consumer”. In many cases it has made things more confusing. Click here to see a pdf of all the new beef names and the old ones side by side. The old names are in the right column. I have highlighted some of the more interesting changes. New names are included below.
In general the cuts that come off the primals can be classified as (1) roasts, which are large thick muscle groups that can feed at least four people, (2) steaks, individual servings that are flat and perfect for grilling, (3) stew meat, chunks cut from odd shaped pieces, and (4) ground meat or hamburger, from scraps.
Meat scientists like the AmazingRibs.com consultant Dr. Antonio Mata have been busy digging around in the bovine carcass for decades in search of muscles and groups of muscles that deliver pleasure and profit. In 2012 Mata created and trademarked the Las Vegas Strip Steak (TM), shown here, from a muscle buried deep in the shoulder. It has a complex steely flavor, plenty of juice, and starts thin but plumps when grilled.
In the past few years he and his peers have created these newcomers, among others: Flat Iron, Petite Tender, Rib Cap, Denver Steak, Ranch Steak, Merlot Cut, Sierra Cut, Santa Fe Cut, Tucson Cut, San Antonio Cut, Round Petite Tender, Braison, Western Griller, Western Tip, and the Flat Triangle. Restaurants are seeking a leg up on the competition by featuring these new cuts.
In the past decade bison has taken off. The meat is similar to beef in flavor, but the muscles tend to have less intramuscular marbling, making them big and bold in flavor and lower in calories. I have tasted and enjoyed a number of cuts from High Plains Bison. I have also tasted other bison that had gamey flavors. Fascinating, but different from grocery store beef.
Below are the most important beef cuts in the US, from a popularity and quality standpoint, and further down is a gallery of photos. The bold names are called “primal cuts” and I have added important subcuts in italics. I will be updating it with the new info shortly.

Tenderness or flavor?
When shopping for meat, the muscles that have the most marbling, the most flecks of fat mixed in with the muscle fibers, are the most flavorful. Often the most tender, the muscles that don’t work a lot, are the most tender. For example, the tenderloin is the most tender cut, and among the most expensive, but it is not the most tasty because it is very lean. Often the harder working muscles are more flavorful, but they are tougher. You can combat the chewiness by proper cooking, usually by reverse sear.
Rib primal or ribeye (about 10% of the meat)
Here’s where the best meat on the steer is found. And the most expensive. The main muscle is the loin muscle, or the longissimus dorsi which runs from between the 2nd and 3rd rib from within the chuck (shoulder) all the way through the sirloin to the hip bone. It is the longest muscle on the animal. There is one on either side of the spine.
The rib primal begins between the 5th and 6th rib and ends between the 12th and 13th rib. Well marbled ribeye steaks are the first choice of connoisseurs, prime rib roast is the ultimate feast for friends and family, and the little known rib cap, the spinalis dorsi, is the best muscle on the animal. These cuts have a perfect balance of muscle and intramuscular fat to produce optimal flavor and juiciness.
Beef ribs come in two sections, the curved back ribs from near the spine, and the straighter, meatier short ribs, from the side, which start here and continue into the short plate and even into the chuck.

- Ribeye steak
- Cowboy ribeye steak
- Eye of ribeye steak
- Rib cap steak
- Back ribs
- Short ribs
Loin (Short Loin & Sirloin 17%)
Here’s a section that can challenge the rib primal for primacy when cooked properly. Again, the main muscle is the longissimus dorsi muscle. The longissimus has many popular names in the loin section: Strip steak, New York strip, Kansas City strip, shell steak, loin, and strip loin.
The other main muscle in this primal is the tenderloin, or psoas major. This is the muscle from which filet mignon and chateaubriand is cut.
Strip is marbled and mouth coating, tenderloin has little fat and is the most tender muscle on the steer. Delightfully, the two come together in T-bone and porterhouse steaks.
The T-bone and porterhouse are similar looking steaks with the two muscles separated by a T-shaped section of backbone. One side of the T has a large section of loin and the other has a small section of tenderloin. The difference between the porterhouse and T-bone is the size of tenderloin. Because the tenderloin tapers like a baseball bat and the T-bone is further to the front of the animal, the tenderloin portion is smaller than on the porterhouse, a minimum of 1/2″ wide at the T. The tenderloin on the porterhouse must be a minimum of 1 1/4″ wide, but they can be up to 3″ wide as you move to the rear.
Sometimes tenderloin/filets are left on the T-shaped bone, sometimes they are removed. Ditto for the loin. Interestingly, porterhouse is getting hard to find because the animals are getting so big that a 1″ steak can weigh a whopping 25 ounces.
Tri-tip is the poor man’s tenderloin, and strip loin roasts can be just as good as prime ribs.

The hind legs put in a lot of work pushing around 1000 pounds or so of beast and thus produce ornery cuts. There are some roasts that must be slow cooked and cut thin, plenty of stew meat, abundant hamburger, and a few steaks that beg for reverse searing: Start low and slow, and sear just before serving.

The sturdy shoulder shoulders a great deal of weight and is a tangled mass of muscles, sinew, and fat. Many impressive roasts and steaks come from the chuck, fine stew meat, not to mention most of the best burgers. At the rear of the chuck, where it connects to the rib primal there are about two steaks called chuck eyes that are practically the same as the vaunted ribeye, only a lot cheaper.

This boneless mass from the chest contains two major muscles, including the pectorals, a thick fat cap, and it is tough as nails unless cooked low and slow. That’s why it is braised in every Jewish household, or smoke roasted in every Texas barbecue joint. And on St. Patrick’s Day cured brisket, corned beef, is simmered with cabbage. Take a slab of corned beef, give it the right rub, smoke it, and you may have the most sublime taste on the steer: pastrami.
- Whole packer brisket
- Brisket flat

Short Plate (6%)
Rife with marbling and layers of fat, this is the meat on top of the rib bones on the side, tough but rich. If cooked gently for a long time, as in a braise of wine and spices, or in air filled with smoke, it turns into the ultimate comfort food. Chefs are discovering that there are some fancy burgers in there.
- Skirt steak
- Hanger steak
- Short plate
- Short ribs
Fore Shank (4%)
A gnarly and knotty knot of twisted muscles and tendons, this is meat best for long slow braises and for soups.
- Shank cross cut
Rich in beefy flavor, with a quick searing char, this flap of flavor is a poor man’s ribeye. But beware, it has long fibers that must be cut across the grain and thin to give up its goodness.
- Flank steak
Offal & Other Cuts
Italians call these meats the “quinto quarto” the fifth quarter. Not popular in the US, they are very common in other countries.
- Ox tail
Meat scientists measure tenderness by using devices that measure the amount of force needed to shear the muscle. Here are the top ten “tender” and “tough” cuts in shear force from the National Beef Tenderness Survey. Shear force is shown as pounds of force to shear one-half-inch cores, removed parallel to the muscle fibers, of cooked muscle from steaks and roasts. Source: Morgan et al (1991).

Cowboy ribeye, a.k.a.tomohawk ribeye
Two of the most desirable steaks, and the largest, and the most expensive, are the T-Bone and porterhouse. Both contain a T-shaped bone with a section of strip (a.k.a. loin, a.k.a. longissimus dorsi) on one side and filet (a.k.a. tenderloin, a.k.a. psoas major) on the other. The main difference between them is the size of the filet. The T-bone comes mostly from the short loin and the filet must be a minimimum of 1/2″ wide below the backbone (bottom of the T). The porterhouse is from the sirloin, and the filet must be at least 1 1/4″ wide below the backbone. It can sometimes be as wide as 3″.
Two loin primals with two porterhouses facing us. At the bottom are the filets, on the top are the strips. If they were joined, they would be called a saddle of beef.
