What dry-aging actually does to a steak
14 August 2026 · By Anna Rieder · Ageing, Beef
Forty-five days in a cold room is not about tenderness. It is about water, enzymes, and a crust you throw away.
People assume dry-aging is a tenderising trick. It is partly that - enzymes in the muscle keep working after slaughter and slowly break down connective tissue - but the bigger change is water.
A rib primal loses somewhere between 15% and 25% of its weight over 45 days. That is water leaving the muscle and taking nothing with it. Everything that made the meat taste like beef is still there, now concentrated into less mass. That is why an aged steak tastes more like itself.
The second thing that happens is the crust. The outer centimetre dries into something like leather, dark and hard, and it protects the meat underneath. It also grows a specific film of moulds and yeasts that push the flavour towards nuts, blue cheese and butter. We trim all of that away before it reaches you. It is the price of admission, and the reason aged beef costs what it does.
How long is right? Twenty-eight days gives you cleaner beef flavour and a firmer bite. Forty-five is our house standard: nutty, deep, still recognisably beef. Sixty and beyond gets divisive - wonderful if you love it, overwhelming if you do not. Ask us for a sample slice before you commit to a whole rib.
One practical note: aged steak needs less time in the pan than fresh. There is less water to boil off, so it browns faster and overcooks faster. Pull it earlier than instinct tells you.
