Why Choose Our PURE WAGYU Sirloin SB 10?
Choose PURE WAGYU Sirloin SB 10 for its unparalleled marble score of 10, offering a buttery and tender experience.
Begin by slicing the primal into your preferred thickness, thicker steaks for searing, thinner cuts for hibachi or sukiyaki-style cooking. Season minimally with sea salt and sear briefly over very high heat. The marbling renders almost instantly, producing a steak of unmatched richness and tenderness.
Pan Sear: Use high heat to quickly render the marbled fat, achieving a crispy crust while maintaining tenderness. Rest for five minutes before serving.
Grill: Medium heat ensures even cooking, allowing the fat to render slowly. Flip once for uniform grill marks and rest for enhanced juiciness.
BBQ: Low and slow on indirect heat tenderizes the cut, while smoky flavors infuse the sirloin. Finish with a high-heat sear for a caramelized exterior.
Oven: Preheat to 180°C and roast gently to preserve marbling integrity. Pair with a quick sear before resting to taste and texture.
This Wagyu sirloin pairs exceptionally well with our condiments such as truffle butters or house-made chimichurri, enhancing its richness and depth of flavour.
Our PURE WAGYU Sirloin SB 10 is carefully packaged to ensure prime condition upon delivery.
The Pure Wagyu Sirloin SB 10 is the ultimate luxury beef experience, a true masterpiece of marbling, reserved for the most discerning palates and the most special occasions.
Striploin, also known as Sirloin, New York Strip, or Porterhouse (when bone-in), is a premium cut prized for its bold flavour and balanced tenderness. It comes from the short loin of the cow and features a fine grain with a satisfying bite. It's a favourite among chefs and home cooks alike for its generous marbling and robust, beefy taste.
All of our beef is from our parent company Stanbroke Beef. This is important as the quality of the beef and ultimately your eating experience is determined by the care that has been shown to the animal during each stage of the production process. Any undue stress the animal experiences at any stage of its life is detrimental to the beef it will produce.
As Stanbroke owns and operates each stage of the production process, strict best practices are followed to ensure the animals always receive the highest of care and that’s why at Peter Augustus we can guarantee the quality of our product each and every time.
The SB Score measures intramuscular fat (the white flecks in the meat). Higher scores mean more marbling, which results in superior tenderness, juiciness, and a richer, buttery flavour.
Vacuum sealing removes air from the packaging, slowing oxidation and bacterial growth to extend freshness and shelf life. When stored correctly at 0–4°C, you can expect the following guide:
For longer storage, keep products frozen at -18°C, where vacuum sealed meat can last 1 to 3 years depending on the cut and consistency of temperature.
Once opened, the shelf life reverts to that of standard fresh products, so we recommend consuming promptly.
For longer delivery routes, some items may arrive partially or fully frozen to ensure they remain within safe temperatures during transit.
Our beef is vacuum sealed to lock in freshness and extend shelf life by removing oxygen. This can cause the meat to appear darker or slightly purplish due to natural myoglobin, which is completely normal.
Once opened, simply let your steak rest out of the packaging for 10 to 20 minutes. As it’s exposed to air, it will “bloom” back to its natural rich red colour. Rest assured, your beef is fresh and perfectly safe to enjoy.
Yes. If the “Use By” date is within range your meat is fresh. Any colour variation from vacuum sealing is normal and will return to its natural red once opened and allowed to bloom.
