✨ The Premium Upgrade You’ve Been Waiting For
Step up from great to extraordinary. The Cape Grim MB4 Porterhouse Striploin takes everything customers love about our original Cape Grim Striploin—and turns the dial up. More marbling. More flavour. More tenderness. Still 100 percent grass-fed, hormone-free and antibiotic-free, but now with an MSA-certified MB4 marble score for a richer, juicier, more luxurious eating experience.
If the original was impressive, this one is unforgettable. It’s the cut for serious steak lovers and chefs who demand both purity and performance—Tasmanian provenance meets elevated marbling perfection.
🌿 Pure Tasmanian Provenance, Elevated
Cape Grim’s farms sit at the edge of the world—Tasmania’s north-west coast—where the air is recognised by the CSIRO as among the cleanest on Earth. This pristine environment, combined with patient, traditional farming, produces beef with unmatched character.
Unlike grain-fed programs, these cattle roam open pastures all year round, feeding naturally on lush grasses. No added hormones. No antibiotics. No chemical interference. The result is clean, ethical beef—but with the MB4 version, you gain an extra layer of tenderness and depth thanks to the higher natural marbling developed through genetics, care and time.
🔍 Why MB4 Matters—The Upgrade Difference
Marbling Score 4 introduces the perfect midpoint between lean and luxurious. You’ll notice slightly richer intramuscular fat streaks that melt beautifully during cooking, basting the meat from within and giving a silky, buttery mouthfeel.
Compared to our standard grass-fed Cape Grim Striploin, the MB4 upgrade offers:
✅ More tenderness—natural marbling softens the fibres and enhances juiciness
✅ Deeper flavour—subtle buttery tones layered over clean pasture freshness
✅ Richer texture—refined grain and a satin-like finish on every slice
✅ Longer finish—a lingering taste of pure Tasmanian beef excellence
