...in Japan - forced fed with beer - cattle who are massaged - you will be amazed.
They are raised and bred specifically for their even marbling. The best way to enjoy is with a larger cut of meat.
Good Wagyu needs no knife. In Japan the lineage of the animals is meticulously recorded and the rating for this beef is monitored by the gov't.
There are some herds outside of Japan, but I would be suspicious about the effort being placed in the animals to get the type of results the Japanese have been achieving for decades.
For those who have been eating it as burger I would challenge the value in that. Wagyu beef is all about the marbling. Grinding everything up and forming a flattened ball defeats that purpose.
You will never see that product in Japan. Also it allows the processor to add the cheeks, lips, toes and anuses into the product for maximum profit from an animal. Yech!
Comparing it to Bison, which I like, is not a fair comparison. Bison is reared for its lean, but lack of "wild" taste. Wagyu is not lean.
Typically Bison is ground because it is so lean many processors add a bit of fat, often pork, to cheat and make it juicier.
If you eat Bison tenderloin you have to keep things on the rare to medium rare side or you will end up with a baseball for a meal.
On the value of Wagyu, that's just personal. Where one will devalue a consumer offering I often see the same person overvaluing something that doesn't make sense to me.
Sort of like NFL football players in a draft.
I would avoid the Kobe beef burger though. Is contrary to the point of the exercise.
