Malting barley for beer, black grass and an agriculture adviser in Tristan da Cunha

A new seed variety is enabling farmers to grow malting barley for beer in places it has previously been too difficult to grow. One farmer shows us around her farm.
We hear about black grass, early British strawberries, and an update from the British Overseas Territory Tristan da Cunha's agriculture adviser.

Presented by Anna Hill and produced by Beatrice Fenton.
