What Does MBS, BMS or MS Mean in Beef Grading?

MBS (Marbling Beef Score), BMS (Beef Marbling Score) and MS (Marbling Score) are grading terms used mainly in Australian and international beef grading systems to measure the amount of intramuscular fat (marbling) in beef.

These scores help consumers understand the eating quality of beef before purchase — especially in premium steak categories like Wagyu and grain-fed beef.

What is MBS vs MS?

• MBS (Marbling Beef Score): Commonly used in Australian beef grading systems (MSA)
• MS (Marbling Score): General term used across multiple grading systems

In practice, both refer to the same concept: the level of intramuscular fat in beef.
