Mutton: Facts

Sheep farming experts generally agree that mutton refers to meat from sheep aged over two years (lamb meat is generally from animals that have been reared for five months).

Until this year, there were no industry-wide standards for meat sold as mutton. Guidelines drawn up by Mutton Renaissance aim to ensure that mutton is consistently of

the quality expected by chefs and homecooks. The standards specify that sheep must be over two years old and must have a forage-based diet (for example, grass, heather and root crops).

Sheep meeting the Mutton Renaissance standard should have a given amount of fat cover, and be matured (for example by

hanging) for at least two weeks. Mutton producers must be able to provide full traceability records, showing where an animal is reared, its breed and age at slaughter.

Although mutton can be available all year, the best meat is produced from October to March. This is because the sheep have access to nutritious summer and autumn grass and heather, and are able to put on fat before being slaughtered. Towards the end of the mutton season, animals are fed on root crops and silage to ensure they reach the

standards Mutton Renaissance requires.

Hebridean, Herdwick, Romney, Shetland, Southdown and Welsh Mountain are just some breeds of sheep with an historical

reputation for producing delicious mutton.
