FAQ
Is this real Japanese A5?
Yes. It is graded A5 by the Japan Meat Grading Association, and every animal is traceable by a 10 digit ID.
What does BMS mean?
Beef Marbling Standard, Japan's 1 to 12 marbling scale. A5 beef scores 8 to 12, and a higher number means more marbling.
How much per person?
3 to 4 oz, or about 2 oz as one course in a bigger meal.
Is A5 the same as Kobe?
No. A5 is a grade. Kobe is a brand from Hyogo Prefecture. Some Kobe is A5, and most A5 is not Kobe.
What is the best way to cook it?
Small pieces seared hot and fast in cast iron. See How to cook above.
