Why we dry-age our beef for 28 days
Every ribeye we serve has spent four weeks hanging in a glass room at 2 degrees. Here is what happens in there, and why we think it is worth it.

What dry ageing is
Dry ageing means hanging large cuts of beef, uncovered, in a cold room with moving air and controlled humidity. Over weeks, two things happen. Moisture leaves the outside of the meat, concentrating the flavour. And natural enzymes inside the muscle slowly break down the fibres, making it more tender.
Our room
The glass cabinet you see as you walk in holds up to 600 kg of beef. It runs at 2 degrees and 80 percent humidity, with a fan moving the air gently around every rib. A salt block wall helps keep the air clean and dry.
Power is the hard part in Port Harcourt. The room sits on its own inverter circuit, backed by two generators, and Sule checks the temperature log every morning and evening.
Why 28 days
We tested 14, 21, 28, 35 and 45 days with our regular guests. At 14 days the difference is small. At 28 the ribeye turns rich and slightly nutty, still clearly beef. Beyond 35 the flavour gets funky, close to blue cheese. Some guests love that, so we keep a few ribs back for 45 day special orders.
Why it costs more
A rib loses about 12 percent of its weight in water over 28 days, and we trim away the dark, dry outer crust before cutting steaks. In total we lose nearly a quarter of what we bought. That, and four weeks of power and space, is built into the price.
How to taste the difference
Order a ribeye medium rare and a fillet side by side for the table. The fillet is aged only 21 days and is mild. The ribeye shows what time does. Or book our grill class, where Sule brings out a 14 day and a 45 day steak to compare.
