The dry-ageing process

Dry-ageing is an age-old process for naturally tenderising beef, which also gives the meat a richer flavour. The meat is hung on the bone in a refrigerated cooler, at a specific temperature and humidity. The process comprises two stages. To begin with moisture evaporates from the muscle, creating a more concentrated, beefy taste; up to 20 per cent of the original weight of the loin (back of the animal) may be lost during dry-ageing.

Secondly, the natural enzymes in the muscles begin to break down fibrous connective tissue, which tenderises the meat. By maturing our Aberdeen Angus beef through the dry-ageing method, we are able to offer beef that is consistently tender and rich in flavour. Only the finest cuts - from the loin and rump - are matured through the dry-ageing process, ensuring that we can provide the very best beef to our customers.
