"An incredible steak, well worth paying the extra for" — Ryan, G
A Cut Above the Rest
Our porterhouse steaks come from native British cattle raised on small, independent farms we know and trust. The 100 day ageing takes it to the very top of the range. Try our 32 Day Grass Fed Porterhouse for the benchmark, or the 100 Day Dry-Aged Ribeye for the same ageing in a different cut.

Frequently Asked Questions
What is a porterhouse steak?
A porterhouse is a large bone-in steak combining two cuts — the sirloin on one side of the T-shaped bone, and the fillet on the other. One of the most generous steaks you can buy.
What does 100 day dry-ageing do to a porterhouse?
Over 100 days, moisture evaporates concentrating the flavour dramatically, while enzymes break down the muscle fibres for exceptional tenderness. A completely different eating experience to a standard steak.
How do I cook a 100 day dry-aged porterhouse steak?
Bring to room temperature for 45 minutes. Season with sea salt. Sear in a very hot pan or over direct flame — 3-4 minutes per side for medium-rare. Rest for at least 8 minutes before carving off the bone and slicing against the grain.
Where does the beef come from?
From native grass-fed British cattle raised on small, independent UK farms committed to regenerative farming. Selected for marbling and flavour, not fast growth.
