M4-5 Wagyu
Learn About the Australian Wagyu Grading System
In Australia, wagyu beef is graded from M0 to M9+ which relates to the degree of marbling the meat contains. Marbling refers to the tiny specs of fat interspersed throughout the lean sections of meat. Generally speaking, the more marbling a cut contains, the higher quality it is considered to be.
In Australia, a pro grader measures the quality and gives it a score from 0 - 9+ so you know exactly how much marbling your cut will contain.
