You'll see "dry-aged" or "matured for 28 days" on steaks in good butchers and restaurants. Here's what it actually means, and why it makes such a difference to the beef on your plate.

What is dry-ageing?

After slaughter, beef is hung, uncovered, in a chilled room with controlled temperature, humidity and airflow, typically for three to five weeks, and sometimes much longer. Two things happen while it hangs:

  1. It becomes more tender. The beef's own natural enzymes slowly break down the muscle fibres.
  2. The flavour concentrates. Moisture evaporates from the meat, so what's left tastes beefier, with rich, nutty, savoury notes that develop over time.

Dry-aged vs wet-aged

Most supermarket beef is wet-aged: sealed in vacuum packs, where it tenderises a little in its own juices but never loses moisture. It's quicker and cheaper, and it keeps all its weight. But it doesn't develop the same depth of flavour.

Dry-ageing is slower and needs space, skill and patience, which is why you'll most often find it at a butcher.

How long is long enough?

  • Around 21 days: a noticeable difference. More tender, with a fuller flavour.
  • Around 28–35 days: the sweet spot for many people. Rich, deeply beefy, and very tender.
  • 45 days and beyond: stronger, funkier flavours. Delicious, but more of an acquired taste.

Why does it cost more?

  • Weight loss. The beef loses a significant amount of moisture as it hangs, so there's less meat to sell from the same joint.
  • Trimming. The outside dries into a hard crust that has to be trimmed away before it's cut into steaks.
  • Time and space. It ties up chiller space and stock for weeks.

You pay for less water and more flavour.

Which cuts are dry-aged?

Dry-ageing works best on the big, prime cuts with a good covering of fat: the rib (ribeye, côte de boeuf), sirloin and rump. Fillet is rarely aged for long, as it's already tender and has little fat to protect it.

How to cook dry-aged steak

Simply. With so much flavour, it needs little more than salt, a very hot pan and a good rest. Dry-aged beef has less moisture, so it browns faster: keep an eye on it. Our guide to cooking the perfect steak has the timings.

Is it worth it?

For a special steak or a celebration roast like a rib of beef at Christmas, we think so. Taste dry-aged and standard beef side by side and the difference is clear.
