Unless you a real foodie or just have lots of money seeking out actual Kobe vs a more available / affordable Japanese A5 ( A5 being a Japanese grading scale similar but different than our select/choice/prime. It has more to do with color appearance texture then marbling.) Japanese meat should have a “A” score ranging from A1-A5, A5 being the best. And a Marble score (BMS) from 1-12, the highest usually being called 12+. So in theory a A5 BMS 12+ would be the best of the best. Most Americans Would not like a 12+ BMS ( as a few noted in this thread that they prefer more traditional American beef) a BMS 5-6 would be about the lv of usda prime, I’d suggest a BMS of 7-8 if trying wagyu as it gives you that “ wagyu experience “ without over doing it.
Japanese wagyu ( including Kobe) is very different then America wagyu and Australian Wagyu. This has to do with genetics, how long they are on “feed” and the feed it’s self. America beef is raised on grass, allowed to graze till anywhere from 1-3 months before they are slaughtered. American beef is fed a rich corn diet to fatten them up. Japanese beef is fed from birth to slaughter and usually is about 12-18 months older then America beef at time of slaughter. There diet as you may guess is more rice based then corn. Kobe ( and some other japaneade wagyu) are fed the left over sour mash from sake distilleries or misu producers . This “ mash” is rice that has been fermented The special bacteria known as koji. Koji is a whole other subject but it’s safe to say it’s one of the most probiotic thing out there. Anyway the “mash” does have some residual alcohol in it by nature Thus the story’s of Kobe being raised on beer. As for massaging , it is true that waguy is pampered more so then most beef, each head being a significant investment to the ranch. America produces / slaughters more beef in a week then the country of Japan does in a year. It’s “ massaging” is done with heavy wood rollers that helps to improve the marbling.
