Trufar's precious black winter truffles are harvested by José Manuel and Eduardo with their gifted truffle dogs Lia and Iris. The truffles are found across 10 hectares of holm and Portuguese oak trees in the Teruel countryside, a region responsible for around 70 per cent of the world’s production of winter black truffles. Their little farm is set at 1250 metres above sea level, with trees planted between 2013 and 2016. For every harvest, the family selects spores from the best specimens. These are then used to inoculate the trees for the next season. Their little farm is set at 1250 metres above sea level, with trees planted between 2013 and 2016.
