Wagyu Sirloin – MB9

About the product

Wagyu is known worldwide as one of the most exclusive types of beef available. Its unique flavour, exceptional tenderness and rich marbling make Wagyu a meat experience beyond the ordinary. This sirloin steak comes from Stone Axe Wagyu in Australia, an award-winning producer specialising in 100% Full Blood Japanese Black Wagyu.

The cattle originate from the classic Japanese Tajima bloodline, the genetic line behind the famous Kobe beef from Hyōgo Prefecture in Japan. Stone Axe imported these genetics to Australia and has since carefully preserved a completely pure Japanese bloodline without crossbreeding with other breeds. The result is beef that comes very close to the quality found in Japan.

MB9 – what does the grading mean?

In Australia, Wagyu is graded according to the AUS-MEAT Marble Score (MB), which measures the amount of intramuscular fat – the fine marbling that makes Wagyu so unique.

MB0–3: low marbling
MB4–6: good marbling
MB7–9+: extreme marbling

This sirloin steak is graded MB9, which represents very high marbling.

For comparison, MB9 roughly corresponds to Japanese A4 to lower A5 on the Japanese BMS scale (Beef Marbling Score), which ranges up to 12. Japanese A5 (BMS 10–12) is often extremely heavily marbled and therefore typically served in very small portions.

In our opinion, MB9 offers the perfect balance – high enough marbling to deliver Wagyu’s iconic melt-in-the-mouth texture and deep umami flavour, while still maintaining a clear meat structure that makes the steak excellent as a classic sirloin.

Farming and animal welfare

Stone Axe operates its own farms in the highlands of New South Wales and Victoria, often at elevations above 1,000 metres. The cool mountain environment provides ideal conditions for raising Wagyu cattle.

The animals are raised in a low-stress environment with plenty of space, fresh air, clean water and natural grazing. The farming follows strict animal welfare principles with a focus on calm handling and sustainable production methods. The beef is also free from artificial growth hormones.

The slow growth and carefully controlled feeding programme give the beef its characteristic fine marbling, deep flavour and exceptional tenderness.

Taste and experience

The dense marbling allows the fat to melt at low temperatures when the meat is cooked. The result is an incredibly juicy sirloin steak with a buttery texture, rich umami flavour and subtle sweetness.

For many meat lovers, Wagyu represents the ultimate steak experience – and this MB9 Full Blood Wagyu from Stone Axe is a perfect example of why.

The meat has never been frozen and is delivered chilled directly to your home in a well-insulated refrigerated box.
