All of these products are from Wagyu cattle, whose genetics famously produce the heavily marbled meat found in Kobe, Japan, and range from 4 - 6 on the marbling scores used by Japan and Australia. Japan, where Kobe Beef first found fame, has now forbidden all exports of Kobe Beef as it has been declared a National Treasure. The science of rearing Wagyu Cattle in Kobe is taken extremely seriously and there are many stories to be heard about both the fantastic eating quality and the immense cost of Kobe Beef when eaten in Japan!!
The non-Welsh wagyu they supply is pretty great and totally different to any other steak I've seen in the UK, better than the £40 one Australasia sold me (£60 now!).
I will be eating Kobe beef in Kobe in June, cost be damned (also spider crab (takaashigani) sushi in Suruga Bay, Shizuoka prefecture).
