The Altair Wagyu Porterhouse Striploin MB5+ is a premium Australian Wagyu primal that brings together refined marbling, natural tenderness, and the unmistakable clarity of grass-fed flavour.
Built on the Altair Wagyu philosophy of Genetics, Grass, and Time, this cut offers a Wagyu experience that is rich yet balanced, indulgent without heaviness.
Finished entirely on pasture, this striploin delivers the silkiness expected of Wagyu while retaining the clean, expressive beef character prized by chefs and discerning home cooks.
Provenance and Production
Altair Wagyu cattle are raised across some of Australia’s most respected grazing regions, including Tasmania, Gippsland in Victoria, and the Limestone Coast of South Australia. These regions provide fertile soils, reliable rainfall, and temperate conditions that support consistent, year-round pasture growth.
Unlike conventional Wagyu programs, Altair cattle are 100% grass-fed and grass-finished, never entering feedlots and never receiving grain supplementation. Extended growth periods allow intramuscular fat to develop naturally, producing fine, even marbling while preserving the freshness and depth associated with pasture-raised beef.
Cut Description and Characteristics
The Porterhouse Striploin is taken from the hindquarter along the spine, a section known for combining tenderness with bold beef flavour.
With an MB5+ marble score, this cut offers generous intramuscular fat, enhancing juiciness without overpowering the meat's natural character.
Key characteristics include:
-
Fine, evenly distributed marbling that melts smoothly during cooking.
-
Firm yet tender texture ideal for slicing or whole-muscle roasting.
-
Clean, pasture-driven flavour unique to grass-fed Wagyu.
-
Exceptional versatility across grilling, roasting, and precision cooking.
Often portioned into sirloin or New York strip steaks, this primal performs equally well as individual steaks or as a centrepiece roast.
Flavour and Eating Experience
Altair Wagyu Porterhouse Striploin MB5+ delivers a distinctive eating experience that sets it apart from grain-finished Wagyu. The marbling provides buttery softness and moisture, while the lean muscle contributes a bright, beef-forward flavour with subtle earthy undertones.
The result is a cut that feels luxurious yet restrained, allowing seasoning, smoke, or simple preparation to shine without masking the quality of the meat.
Best Cooking Methods
This striploin rewards precision, patience, and respect for the cut:
-
Grilling or Pan-Searing: Slice into thick porterhouse steaks and cook over high heat to form a caramelised crust while maintaining a juicy, medium-rare centre.
-
Reverse Sear: Slow-cook at a low temperature, then finish with a hot sear for even doneness and maximum moisture retention.
-
Whole Striploin Roast: Roast gently to allow the marbling to render slowly, producing a tender, flavour-rich centre ideal for carving.
-
Sous Vide: Precision cook for consistent results, finishing with a quick sear to build colour and texture.
