Cape Grim: Pure Tasmanian Provenance
Cape Grim cattle are raised in Tasmania’s far north-west, a region known for its clean air and pasture-driven farming systems. Cattle roam open pastures year-round, feeding naturally without grain supplementation.
No added hormones. No antibiotics. No chemical interference. The beef is produced through traditional farming practices and graded under the MSA system to ensure consistency and quality.
This environment and approach produce beef with clean flavour, reliable performance, and strong ethical credentials.
Why MB4 Marbling Makes the Difference
Marbling Score 4 represents a refined balance between lean structure and indulgent richness. Fine intramuscular fat melts during cooking, basting the meat from within and improving juiciness, tenderness, and mouthfeel.
Compared to the standard Cape Grim Striploin, the MB4 version offers greater softness, deeper flavour development, and a more lingering finish. The result is a steak that feels more luxurious while retaining the clean pasture character Cape Grim is known for.
About the Cut: Porterhouse Striploin
The porterhouse striploin is prized for its consistent shape, even thickness, and reliable cooking performance. Cut from the short loin, it delivers strong beef flavour with a refined grain structure.
In the MB4 grade, this cut gains added tenderness and a smoother texture, making it ideal for high-heat cooking, controlled roasting, or precision sous vide preparation.
Best Ways to Cook It Right
This cut performs best when cooked with restraint and care, allowing the marbling to do the work.
Bring the meat to room temperature before cooking. Season simply with salt and cracked pepper to highlight the natural flavour.
Sear over high heat for two to three minutes per side, then finish gently to an internal temperature of 52°C for medium-rare. Rest for around 10 minutes before slicing across the grain to maximise tenderness and presentation.
Flavour Profile: Clean, Rich, and Balanced
The Cape Grim MB4 Porterhouse delivers a clean pasture aroma paired with a subtle buttery richness from its increased marbling.
The texture is juicy and refined, with fine fat streaks melting smoothly through the meat. Each slice offers balance, clarity, and depth without heaviness, reflecting both its Tasmanian origin and elevated marbling score.
