Steak Wagyu Beef in Fourties Kemang

The wagyu steak comes from good quality beef at all.

 so this is story from wagyu beef. 

 Japan High grade sliced Matsusaka wagyu beef (rib section meat) Because of Japan's rugged terrain and isolated areas, different breeding and feeding techniques were used such as massaging or adding beer or sake to their feeding regimen.[citation needed] It is suggested that this was done to aid in digestion and induce hunger during humid seasons, but it appears to have no effect on the meat's flavor. Massaging may have been introduced to prevent muscle cramping on small farms in Japan where the animals did not have sufficient room to use their muscles.

[2] There are four breeds of wagyu: Japanese Black (黒毛和種 Kuroge washu ?), Japanese Brown (赤毛和種 Akage Washu ?), Japanese Polled (無角和種 Mukaku Washu ?), and Japanese Shorthorn (日本短角和種 Nihon Tankaku Washu ?).

[3][4] Japanese Black makes up 90% of all fattened cattle in Japan.

[5] Strains of Japanese Black include Tottori, Tajima, Shimane and Okayama.

[6] Japanese Brown, also known as Japanese Red,

[5] is the other main breed;

[6] strains include Kochi and Kumamoto. Japanese Shorthorn makes up less than one percent of all cattle in Japan.

[7] Australia The Australian Wagyu Association is the largest breed association outside Japan.

[8] Both fullblood and wagyu-cross cattle are farmed in Australia for domestic and overseas markets, including Taiwan, China, Hong Kong, Singapore, Indonesia, the U.K., France, Germany, Denmark and the U.S.A.

[9] Australian wagyu cattle are grain fed for the last 300–500 days of production. 

Wagyu bred in Western Australia's Margaret River region often have red wine added to their feed as well. United States In the United States, Japanese Wagyu cattle were bred with Angus cattle. This crossbreed has been named American Style Kobe Beef.[10] Designed to mimic the diet that Japanese cattle were receiving, Wagyu cattle in the United States are fed a mixture of corn, alfalfa, barley and wheat straw. In Colorado Wagyu beef is being marketed by a ranch near Basalt, Colorado, and by a ranch near Rush, Colorado. Wagyu were first competitively exhibited at the National Western Stock Show in 2012.[11]
