Our final stop was a newly-planted truffle plantation (complete with helipad) established by Baron de la Truffe founder Serge Desazars de Montghaillard, who has been cultivating black truffles since 1996. With around 40 hectares of organically-grown trees, he harvests black Périgord truffle using dogs and has recently launched his own book featuring recipes using the prized culinary ingredient. The region is a major truffle producer and holds a series of markets in the truffle season (November to January).
