Kobe is always Wagyu, but not all Wagyu is Kobe! From humble work animals… to the high stakes of the Japanese economy.

Even among the most devoted meat lovers, some believe that the celebrated Wagyu and Kobe meats come from two ancient, purebred, indigenous beef cattle breeds of Japan. However, meat was not always part of the Japanese diet. If we looked back at the history of livestock farming in this country, we would discover that the first cattle—because of their sturdy build and natural endurance—were brought from China to Japan sometime between the 5th and 3rd centuries BC to meet farmers’ need for work animals, beasts of burden for plowing and transporting ore or timber. Since Buddhism prohibited its followers from eating beef at the time, the Japanese, who did not even customarily consume dairy products, continued for centuries to use these animals exclusively for agricultural work. 

The history of Wagyu, then, begins sometime in the late 19th century, when Emperor Meiji the Great regained power. From then on, Japan began to develop, transforming from an inward-looking feudal state into an industrializing superpower. With the restoration of imperial rule, a period of reform (Westernization) began, and Japanese customs and eating habits changed. The ban on eating meat was lifted, and beef took its place in Japanese cuisine. After 1868, as many Japanese became familiar with European and North American customs and everyday practices, eating beef became fashionable in the major cities. Encouraging this consumption can be seen as part of the new regime’s efforts to reshape the Japanese physique in a way that would make it more appealing to Westerners, thereby facilitating Japan’s entry into the ranks of countries where the average height was greater than in Japan. To promote this goal, the government supported beef production and consumption. In 1871, it abolished the monopoly on meat production held by hereditary groups, and in 1872 it made public both the emperor’s position and the essay “On Eating Meat” by thinker Fukuzawa Yukichi, as well as related discussions among intellectuals, promoting literary depictions of new ways of life. Thus, although Wagyu beef was developed and raised in Japan, its incorporation into Japanese cuisine is in fact clear evidence of Western influence on Japanese customs, and marks a significant turning point in Japanese history. 

In the 1880s, the Japanese decided to import animals from European cattle breeds and crossbreed them with Japanese cattle. This transformed the old working breeds into beef breeds. Several cattle breeds emerged from this process, and they continue to dominate the Japanese beef trade today. However, only four of these breeds are truly Wagyu:

Japanese Black | The Japanese Black breed, whose meat is prized for its intense marbling. Since 90% of Wagyu cattle belong to the Japanese Black breed, when people say “Wagyu,” they usually mean Japanese Black cattle. 
Japanese Brown | The Japanese Brown breed, a leaner, healthier cattle breed known for the mild flavor of its meat. 
Japanese Shorthorn | Japanese Shorthorn. Although also lean, Japanese Shorthorn beef is rich in inosinic and glutamic acids, two valuable acids that give it a more savory flavor. 
Japanese Polled | Japanese Polled: Like Brown and Shorthorn, Japanese Polled beef is lean and is renowned for its more pleasant texture and rich, meaty flavor.

In the beginning, there was a black cow
Everything you need to know about Wagyu beef and especially Kobe beef  
“Wagyu” refers to any cattle raised in Japan or … in the Japanese style. In a loose translation, Wagyu means “Japanese cattle” (“Wa” means Japanese or Japanese-style, and “gyu” means cow or cattle in general). Simply put, “Wagyu” means “Japanese cow.” For Wagyu beef to be classified as Kobe, it must come from a very special member of the Wagyu breed, called Tajima-Gyu, raised under strict protocols in Hyogo Prefecture.  Since Wagyu beef was often transported from Kobe to Yokohama – the commercial port in the Tokyo metropolitan area – it began to be highly prized by the foreigners living there. Its admirers are also credited with the slogan: “What other, Kobe beef!” 

But what makes Wagyu stand out from other types of cattle? And what makes Kobe beef so special that it often commands some of the highest prices per kilogram on the market? 
Farmers who raise Wagyu cattle do so with exceptional care. They feed them milk until they are 3 months old. After three months, the calves are fed a mixture of grass, rice straw and grains (corn, soybeans and wheat). Kobe cattle are fed the same diet as all other Wagyu, but each farm varies the feed it gives its cattle slightly. In addition to corn or cornmeal, which is essential, they add oats, wheat, barley, soybeans, as well as sugarcane silage or cacao nibs (fragments of the seeds inside the cacao fruit). Most animals also eat straw and hay, as they would in their natural habitats. It is worth noting that in recent years two farmers, one in Japan and one in the Netherlands, have adopted a different diet enriched with a tasty, digestible and safe paste made from pure olive pulp, derived from roasted olive mill “waste.” 

It is sometimes said that farmers massage their cattle to reduce muscle tension caused by cramped spaces.
There are many myths about raising Wagyu. It is said that they live in spa-like conditions, are given “gourmet” feed, are massaged with beer, and listen to classical music to help them relax. Although none of these myths has been debunked, that does not mean they are the norm. Producers follow very strict rearing guidelines, and some have indeed developed special methods that allow Wagyu to live at an unhurried, relaxed pace. They may listen to music, but it is not essential. What is certain is that the calm, unhurried life of these cattle helps increase their intramuscular fat (marbling) and contributes to its unique distribution, which makes Wagyu beef so delicious and sought-after. Its “veining” - the fine white streaks of fat that melt as the meat cooks - help it stay tender, juicy, and therefore flavorful. And because its fat’s melting point is lower than the average human body temperature, it melts pleasantly in the mouth. 

Part of its appeal is its aroma, a unique, sweet coconut scent. A relatively recent study in the Journal of Agricultural & Food Chemistry identified sixteen compounds that give it this distinctive aroma, ten of which are directly associated with the meat. The strongest evidence, however, comes from compounds derived from fatty acids. The excess fat, its distribution, and the different composition of its fatty acids are due, on the one hand, to a genetic trait of this particular cattle breed and to its diet, which allows intramuscular fat to make up 30 - 40 % of the muscle’s volume, and, on the other hand, to the fact that the calves continue to be raised until they are 30 months old.  

Marbling: What sets Wagyu apart
The result of these breeding methods, combined with longer fattening periods, is what gives Wagyu beef its superior flavor. Marbling gives Wagyu better flavor. Its fat melts at a lower temperature than that of any other cattle breed, resulting in a rich, buttery taste not found in meat from other breeds. This fat is unsaturated and rich in omega-3 and omega-6 fatty acids, which means marbling makes it not only tastier, but healthier too. Despite the breed’s genetically increased predisposition to developing intramuscular fat, Wagyu also produces a high proportion of unsaturated fats, such as omega-3 fatty acids, which balance out the corresponding proportion of omega-6 fatty acids and therefore help reduce bad cholesterol and fight heart disease. 

Quality grading of Wagyu beef 
Another very important factor that determines Wagyu quality is its grade. In some specialist butcher shops or on the menus of high-end steakhouses, you’ll often see an A5 rating. This is the grade assigned to it by members of the Japan Meat Grading Association. The grades, marked with letters from A to C, refer to the yield of saleable meat from each cow. A is the highest yield grade and C the lowest. Each letter is followed by a number (from 1-5), which indicates the quality grade: 5 is excellent, 4 good, 3 average, 2 below average, and 1 poor.  
The assessment is based on four criteria:  
1. The marbling (the distribution of intramuscular fat in the meat) 
2. The color of the meat, in relation to its brightness 
3. The firmness and texture of the meat  
4. The color, in relation to the shine and quality of the fat  

As for the «Sashi» grades (i.e., marbling in Japanese), there is also a further assessment, the Beef Marble Score (BMS), on a scale of 1-12. 
According to the BMS, exceptional intramuscular fat is rated 8-12, good is rated 5-7, medium 3-4, the next lower grade 2, and the minimum 1. So A5 is top-quality Japanese Wagyu, and therefore the most expensive. The best score an A5 could receive is A5-12, which is extremely rare. Understanding the logic of this grading system helps you buy or order at a restaurant the meat you want to pay for. 
All these facts help explain, in a way, why in countries such as the United States the cost of the finest Wagyu steaks easily exceeds $300.  
After all, a live Wagyu cow can cost as much as $30,000. In 2002, a Wagyu cow sold in Japan for about $400,000. It was a record, and remains the highest price ever paid for such a cow. 

And Wagyu burgers?  
Is it really worth ordering a Wagyu burger? I’d say probably not. All the appeal of Wagyu beef lies in its distinctive texture, excellent marbling, and tenderness. So, while grinding the meat into mince and turning it into patties or burgers will make it tender, the difference in taste compared with any other (regular) burger will be slight to imperceptible.
