FAQ
What does 'Australian Marble Score 9' mean?
It's a grading system (AUS-MEAT) that rates marbling from 0 to 9+. A score of 9 indicates 'very high' marbling, with an extensive, fine web of intramuscular fat throughout the muscle.
How should I cook this premium steak?
Due to its high fat content, it cooks quickly. Use high, dry heat: sear in a very hot cast-iron skillet or on a grill for a deep crust. Cook to medium-rare or medium to keep it tender and juicy, as overcooking can cause the fat to render out excessively.
Is this the same as Japanese Wagyu?
Not exactly. Australian Wagyu is typically a crossbreed (e.g., Japanese Wagyu genetics with Australian cattle), raised in Australia. It follows similar feeding practices to develop marbling but may have a slightly different flavor profile and grading scale than the strict Japanese system.
