Top Sirloin Center Cut F1 Wagyu MB6-7

$8.99/lb

Sourced from Jack’s Creek, this Top Sirloin Center Cut — known as a Rostbiff — is cut from Wagyu cattle crossed with Black Angus, bred and grown across the prime grazing country of New England, New South Wales, and Victoria’s Riviera region, raised free-range in a natural, clean environment.

Grain-fed for 400+ days with no added hormones on a specially designed diet, this F1 Wagyu develops rich, even marbling (Marble Score 6–7). The Rostbiff is derived from the D Rump by fully removing the surrounding connective tissue and smaller muscles, leaving only the clean gluteus muscle group — a lean yet flavorful center-cut roast.

  • F1 Wagyu-Angus cross, Marble Score 6–7
  • Boneless center-cut Top Sirloin (Rostbiff)
  • Grain-fed 400+ days, no added hormones
  • Processed under strict Australian Quarantine and BRC Global Quality Assurance standards

A lean, richly marbled roast — excellent for searing whole or slicing into center-cut steaks.
