Why King River Wagyu Reigns Supreme

What makes this brisket stand out from the rest? Here are the top reasons it reigns supreme in the world of slow-cooked perfection:

  • Premium Victorian Grazing: King River offers fertile soil, clean water, and wide-open pastures. These ideal conditions produce calm, healthy cattle with superior meat texture.
  • Purebred Wagyu Genetics: Unlike many crossbred alternatives, this is 100 percent purebred Wagyu. The genetics are true to Japanese lineage and deliver exceptional consistency and depth of flavour.
  • Long-Term Grain Finish: A 400-day minimum grain-fed program means controlled nutrition that enhances marbling and delivers beef that is rich, balanced, and tender throughout.
  • Deckle-Off Precision: By removing the deckle, this brisket has a more uniform thickness and shape. That means better smoke absorption, easier trimming, and flawless plating.
  • Ethical and Responsible Farming: Farmers at King River are committed to sustainable practices and high animal welfare standards, ensuring that every cut supports quality and care.

The 8–9+ Marbling Experience

Marbling is not just about fat content. It is the difference between a chewy brisket and one that melts in your mouth. MB 8–9+ brings you the kind of beef that makes people stop mid-bite and say “wow.”

  • Fat Where It Matters: With marbling woven throughout the muscle fibres, every slice is naturally basted from the inside as it cooks.
  • Juicy, Tender Texture: That fine fat melts low and slow, giving you meat that is moist, tender, and buttery soft from edge to edge.
  • Unmatched Depth of Flavour: MB 8–9+ brisket delivers bold umami flavour with a rich, lingering finish. It is satisfying without being overpowering.
  • Built-In Forgiveness: The marbling gives you more room for error. Even if you are not a seasoned pro, this brisket helps you get closer to competition-level results.
  • Satisfyingly Consistent: With a high and predictable marbling score, you get consistent performance every time you cook it.

Best Ways to Cook It Right

There are a few tried-and-true ways to bring this brisket to life. Here are our favourites:

1. Smoking

Preheat your smoker to 120°C. Apply a generous dry rub, then cook fat-side down until the bark is set, typically around 6 to 8 hours. Wrap in butcher paper, continue until the internal temperature hits 93°C, then rest for at least an hour. Expect dark bark, jelly-soft fat, and slices that fall apart without falling to mush.

2. Sous Vide

Set your sous vide bath to 65°C. Vacuum seal the brisket and cook for 36 hours. Once done, sear it in a cast-iron pan or use a torch for a caramelised outer layer. This method produces ultra-moist beef with precise doneness.

3. Oven Roasting

Season and marinate overnight. Roast at 140°C in a covered tray for 6 to 8 hours. Remove the cover during the final 30 minutes for a crisp finish. Serve with your favourite sides for a complete feast.

Pair with: Creamy mash, grilled corn, chimichurri or baked mac and cheese.
 Drink with: Malbec, Shiraz, or a dark stout.
