Buying Beef: The Science Of Beef Grades And Labels, And Busting The Kobe Beef Myth
"Know fat? Know flavor. No fat? No flavor." Anonymous chef
Vitamin beef. Flesh of bovine. Is there anything more luxurious and decadent than a prime grade dry aged ribeye grilled over high heat? Cattle are butchered and can be broken down into into many different cuts. The most popular use of beef is for steaks, roasts, and ground meat, but everything from the tongue to stomach to testicles are served. Even the bones are used for stews and soups.
Beef comes from both steers (boys) and heifers (girls), and the best comes from mature, but not old animals. Young animals, calves, are used for veal. Older, tougher animals are best used for ground beef.
There are some very helpful terms used to describe beef and many appear on labels. It pays to know them when you shop.
Marbling. Starting in 1926 the United States Department of Agriculture (USDA) began grading beef. Today inspectors grade primarily on the age of the animal and the amount of fat mixed in with the muscle as measured between the 12th and 13th rib. This fat is called marbling because it resembles the striations in marble: Thin, weblike filigrees. The more marbling, the more flavor and juiciness, but marbling has little tenderness impact. Marbling can contribute a lot to the quality of a steak because fat is where the flavor's at.
But marbling is costly. According to the AmazingRibs.com beef scientist, Dr. Antonio Mata, "Marbling is the most expensive fat the animal generates. Like humans, cattle first deposit fat in the gut. Secondly they deposit subcutaneous/surface fat. Then they deposit fat between muscles, intermuscular fat. And lastly they deposit intramuscular fat, a.k.a. marbling. Therefore marbling is a highly inefficient, slow, expensive process." And we pay for it. Highly marbled meat also shrinks more when cooked as the fat drips off. And we pay for that too.
USDA Utility, Cutter, Canner Beef. These are the lowest grades of beef and used primarily by processors for soups, canned chili, sloppy Joe's, etc. You will not likely see them in a grocery.
USDA Standard or Commercial Beef. Practically devoid of marbling. If it does not have a grade on the label it is probably standard or commercial. These grades are fine for stewed or ground meat, but they are a bad choice for the grill.
USDA Select Beef. Slight marbling. Most restaurant brisket is this grade. If you know what you are doing you can make this stuff tender. Otherwise, get a higher grade. About 2 to 4% fat.
USDA Choice Beef. Noticeable marbling, but not a lot. This is a good choice for backyard cooks. About half of all beef is marked USDA Choice. There are actually three numbered sublevels of USDA Choice. Certified Angus Beef (CAB) is limited to only the top two levels. Reliable sources tell me that Walmart "Choice Premium" is USDA Choice. The word "premium" is all about marketing and not to be confused with USDA Prime. About 4 to 10% fat.
USDA Prime Beef. Significant "starry night" marbling. Often from younger cattle. Prime is definitely better tasting and more tender than Choice. Only about 3% of the beef is prime and it is usually reserved for the restaurant trade. About 10 to 13% fat.
Black Angus. Black Angus cattle are considered by many to be an especially flavorful breed. Alas, it is almost impossible to know if what you are buying really is Angus.
Certified Angus Beefª. The Certified Angus Beefª (CAB) brand is a trademarked brand designed to market quality beef. To wear the CAB logo, the carcass is supposed to pass 10 quality control standards and CAB must be either USDA Prime or one of the two upper sublevels of USDA Choice. Most of it is USDA Choice. CAB costs a bit more because the American Angus Association charges a fee to "certify" the steers and higher markups take place on down the line.
Interestingly, CAB does not actually certify that the beef labeled Certified Angus Beef is from the highly regarded Angus breed. Their major control is that the steer must have a black hide, which is a genetic indicator that there are Angus genes in the steer, but not a guarantee.
Busting the Kobe Beef myth
Kobe Beef. Kobe Beef comes from Tajima-gyu cattle, a special breed that is genetically disposed to have high marbling. It was first popularized in the city of Kobe in Japan. It is highly regarded by connoisseurs for its flavor, tenderness, and most of all, the richness that comes from a high percentage of marbling whose chemistry makes it melt in your mouth, like butter.
Kobe cattle are fed mash left over from making sake and beer during the final fattening stages. A few may be massaged by loving owners, but it is not a normal part of their cultivation. Interestingly, some American cattle (and hogs) are fed spend mash from beer and whiskey production.
They have their own grading system. Some of it is graded A1-A5 with A5 having the most marbling. Some of it is graded with a marbling score called BMS. USDA prime is 4 to 5 BMS (10 to 13% fat). Kobe and a few other types of special Japanese beef can go up to 12 BMS (up to 40% fat) because of their genetics, feed, and handling.
There are no Tajima-gyu known to be living outside Kobe, and until late 2012 real Kobe beef was not allowed into the US. Until then, everything labeled Kobe was falsely labeled. Fake. Fraudulent. Phoney. Bogus. Disgraceful. It was probably American Wagyu at best.
Some analogies: Champagne is a region in France. A "Champagne" from California is similar, could even be better, but it is not real Champagne and it is usually not even made from the same grapes. Idaho potatoes come only from Idaho, not France or Japan. Could you imagine the lawsuits if they grew potatoes in Japan and called them Idaho potatoes? Parmigiano-Reggiano is the real parmesan and it comes only from the area around Parma and Reggia in Italy, never from a green toilet paper tube. Maine lobster looks and tastes different than Florida lobster. Florida lobsters have no claws. Can you imagine ordering Maine lobster and not getting claws? In these cases, there is more to it than just a name. Real Kobe is truly different than any other meat in the world. Just look at the price.
If you know a restaurant that advertised Kobe beef prior to mid 2012, then they are likely selling mislabeled fish, too. Beware.
Wagyu Beef. Wagyu cattle have Japanese blood lines and are now raised in the US and other countries. Their genetic heritage can be any of a number of Japanese cattle. American Wagyu does not have to adhere to the standards as Kobe beef, and many of the Wagyu are cross bred with local breeds to make them better adapted to the local climates and diseases. Wagyu and Angus crosses are frequent, and they make mighty fine meat. Wagyu is usually extremely marbled, usually 4 to 10 BMS, more than USDA Prime, but not as much as Kobe, and the flavor and texture is distinctive. It is also about twice the price. One can only wonder how long before the cross breeding and lack of enforceable standards dilute the quality.
If you want to try some amazing real Wagyu, I have links to top suppliers on our artisan foods page. That's a cross section of a Snake River Farms wagyu flat iron steak above. The meat is simply incomparable, shot through with thin whisps of buttery marbling. Go for the ribeye or striploin. Do not die without having tasted great Wagyu.
That said, I do not recommend buying Wagyu hamburger which is essentially pre chewed meat, and which might have non-Wagyu fat in the blend.
But if you're after the big bux in a barbecue or steak competition, beware, the guy next to you is using a Wagyu brisket.
After cattle are slaughtered chemical changes called rigor mortis makes the meat tough within the first 12 hours. The carcass must be chilled rapidly but not frozen, and it takes a couple of days for the muscles to relax enough to be sold. This usually happens in shipment. After that it can be further aged, or ripened, to increase tenderness. Enzymes and oxygen begin to work on the meat during the aging process, but too much age can spoil the meat, especially if bacteria, yeasts, or molds attack the meat. There is a big difference between aged meat and old meat. In addition, aging does not enhance all cuts, and it is not necessary for ground beef. Pork and most poultry do not age well at all because their fats get rancid more rapidly than those of beef.
Fresh. This seemingly desirable term means the meat has not been aged at all, so, unlike fruit, it is actually not a sign of highest quality.
Wet Aged Beef. Most meat is shipped from slaughter houses as large wholesale cuts packed in plastic vacuum bags in boxes. If kept this way at 34 to 38°F for about 30 days, enzymes tenderize the meat, but the flavor is not as enhanced as it is in dry aging. If you buy vacuum packed beef that has not been aged, keeping it in the fridge for 2 to 3 weeks may tenderize it a bit.
Dry Aged Beef. Dry aging beef is an expensive process for tenderizing beef and concentrating its flavor. Dry aged beef is noticeably different tasting than fresh beef because the chemistry of the fat changes drastically. Some describe it as earthy, nutty, gamey, leathery, or even mushroomy. Some people are addicted, some just plain don't like it.
Large hunks meat, usually the best cuts such as the rib primal (section), are held in a sanitary room at 34 to 38°F and 70-80% humidity, with brisk airflow for 30-75 days. Dry aging is sometimes called controlled rotting because the exterior of the muscle gets dark purple and mold sometimes grows on the outside of the meat.
In the picture above we see bone-in rib primals in the aging locker of David Burke's Primehouse in Chicago. They range from, left to right, 7 days, 20 days, 30 days, and 60 days.
During aging natural enzymes break down connective tissue and tenderize the meat while moisture evaporates shrinking the meat up to 20% (fresh beef is about 70% water). The outside crust is trimmed off before they are sliced into steaks and cooked, so another 15% is lost, although some of the trimmings are used in Primehouse's incredible hamburgers. Aged steaks there sell for a bit less than $1 per day.
It is rare to find dry aged beef in grocery stores because most of them buy their meat in vacuum packed plastic bags. Some specialty butchers and high end restaurants offer dry aged beef. Because precise temp and humidity control are crucial, you should not try dry aging at home.
Grass Fed Beef. Until the 1950s, most US beef was grass fed right up to slaughter by being allowed to graze on open ranges. As the US population grew and demand for cheap beef grew, corn feeding of beef became the norm. Now there is a trend back to grass feeding because many believe it is better for the animals, for people who eat them, and the environment. Some people think grass-fed beef taste better than grain fed, but more think corn fed tastes best. There is a difference in taste. Grass fed beef can have a mineral quality. It can be very distinctive and have more personality than corn fed and many people, especially old timers raised on grass fed love it. Alas, many people aren't charmed by its personality.
Grain or Corn Fed Beef. For most of their lives, and especially just before slaughtering, most cattle in the US are fed corn. These cattle have slightly more fat and many people prefer the taste. Cattle love corn, but they do not easily digest it. The process is popular because the animals can be kept in tight pens in feed lots and do not have to graze over open land, and because the meat can be tender, juicy, and sweet.
Grass or Corn Finished. Before slaughtering some cattle are brought to feed-lots where they are gorged and fattened. Sometimes grass-fed cattle are corn finished, so consumers who are concerned about corn feeding might also inquire if their grass fed cattle have been corn finished. It's getting complicated out there...
Organic Beef. USDA rules passed in 2002 state that certified organic beef must be produced according to strict rules that must be verified with an elaborate paper trail on every animal including its breed, feed, and medical history. To be certified organic it must eat only organic grasses and grains, have unrestricted outdoor access, must never be given antibiotics or hormones, and must be treated humanely. Organic beef is more expensive.
Natural Beef. Natural beef must not be given antibiotics or hormones, but they can be grown, fed and handled in the same way as other common cattle. Some physicians and scientists think giving cattle antibiotics could be encouraging the appearance of antibiotic resistant microorganisms in humans.
Kosher Beef and Halal Beef. These cattle are grown and slaughtered according to Jewish law (kosher) or Moslem law (Halal). Their requirements are similar. Both require that the animal be slaughtered by slitting the animal's neck veins and drained of practically all blood. Some experts believe this method is painful and inhumane.
Where beef is heading
There is a rapidly growing vital movement to grass fed beef, sustainable beef, varietal beef, and even estate grown artisan beef. I think this movement will really catch on in the next decade as quality conscious and environmentally conscious consumers look for top quality, new flavors, and try to avoid factory farmed beef. The movement reminds me very much of what happened to the wine industry in the 1960s (yes, I'm that old).
Beef farming husbandry has been the subject of a great deal of controversy in recent years. The subject is much too large to cover here, and is discussed thoroughly in such books as Michael Pollan's brilliant book, the Omnivore's Dilemma, but here's a summary:
Beginning with the Nixon administration, under Agriculture Secretary Earl Butz, US farm policy shifted billions of dollars to encourage and subsidize cheap corn. Corn is a miracle plant. Corn derived products can be found in about half the foods in your grocery store. It is also a great way to make farm animals grow large and fat quickly. With government help, research has significantly increased corn yield per acre. Meanwhile, the number of buyers for corn has decreased, with the vast majority being purchased by Cargill and Monsanto. This has limited the market and put the squeeze on corn farmers while, at the same time, driving down the cost of corn. This makes many food products cheaper, from soft drinks to beef, not only in the US, but around the world. It has had the unpleasant side effect of pricing home-grown foods out of the market in many Third World nations, especially Africa, depressing the local economies, and transferring profit to US agribusiness multinational giants.
As corn prices dropped, another farming revolution was taking place. The family farm began disappearing. After WWII, in the late 1940s, about 20% of the population was involved in farming. That number is down to about 2%. That's because new technologies emerged and mass production concepts were adapted from the manufacturing industries. Among them were the use of steroids and hormones to speed animal growth. One of the most notable techniques to emerge was the appearance of concentrated animal feeding operations (CAFOs).
Most cattle are birthed and raised on farmer owned ranches where they are well cared for and get a mixed diet of hay and grains. But when they are close to slaughter, they are sold to CAFOs where they are switched to a diet of corn mixed with supplements, among them antibiotics to combat diseases that can be problematic in such tight quarters. Corn has the added benefit of making beef taste better because it can encourage better marbling. On the other hand, it can create digestive problems in cattle, which are ruminants, and genetically better suited to digesting cellulose, like grass. Corn's high carbohydrate concentration can make them susceptible to digestive problems and the jam packed quarters cattle are kept in on CAFOs.
Many physicians are concerned that widespread use of antibiotics in farm animals, not just cattle, is allowing antibiotic resistant bacteria to generate, and they may jump to humans. Others are concerned that, despite research to the contrary, antibiotic, steroid, and hormone residues remain in the meat.
As a result, consumers and farmers have found common ground and are spearheading a movement to a new way of growing beef. As an example, a ranch might select a bull whose bloodlines and offspring have proven to be high quality, much like race horses are bought at auction. They grow their cattle on a mix of grass and grain, allowing them to graze. This means more land is needed, and animal growth is slower, so costs are higher. They then slaughter, butcher, and market directly to consumers from the ranch, via the internet, via catalog, at farmers' markets, and in specialty stores. At a higher price.
There are a number of luminaries and visionaries in the movement, among them Carrie Oliver who has created the Artisan Beef Institute, where she disseminates info about artisan beef producers and sponsors tastings. You can even buy a tasting of beef from different artisans for sharing with friends and the carnivore's answer to a wine tasting. She says that many things influence the flavor of a steak, including the steer's diet, the treatment of the cattle, the time of year, and even the vintage. She predicts that steaklovers will start asking for their favorite breeds, areas of origin, ranchers, and even butchers.
I think she is right. I predict big things for this movement.
