Wagyu Marbling & Grading Guide
Marbling is the fat within the muscle that gives Wagyu its distinctive appearance. For wholesale buyers, understanding the grading label helps you compare options for a butcher counter, specialty market, or restaurant menu.
How the grading systems differ
| Origin / system | What the label means | What to check |
|---|---|---|
| Japanese Wagyu | Yield grades A–C and quality grades 1–5 combine in labels such as A5. A and 5 are the highest in their respective categories. | The letter describes yield; the number describes meat quality, including marbling, color, and texture. |
| Australian Wagyu | AUS-MEAT marbling scores are commonly presented as 0–9+, describing the amount of visible intramuscular fat. | Confirm the grading system used. AUS-MEAT and Meat Standards Australia (MSA) scores are different. |
| USDA beef grades | Prime, Choice, and Select are quality grades that consider marbling and maturity. | Confirm the USDA grade separately from the product's Wagyu breed or genetics description. |
These systems measure different things. Treat comparison graphics as a general reference, not an exact conversion between Japanese grades, Australian scores, and USDA grades.
