This Japanese Wagyu loin A5/A5+ and BMS 10-12 comes in a small piece of approximately 500 g. It offers an alternative to the large whole loins when you want to prepare a very marbled meat tasting. Graduation comes from the producer's trade name and should be kept distinct from A4 or Australian-origin cuts.
In front of the A5 loins that are sold for several kilos, this 500 g piece facilitates a more contained tasting. The A5/A5+ and BMS 10-12 identification comes from the product's trade sheet and should be checked with the weight.
