Wagyu beef refers to beef produced from 4 distinct cattle breeds found only in Japan. These cattle are fed a rich carbohydrate diet that allows them to put on dense intermuscular fat. Grading of Japanese Wagyu beef is strictly done by the Japanese Meat Grading Association. A5 is the highest grade and yields a rich taste and velvety texture that will linger on the pallet, truly an experience not matched by any other beef.
