context_page_description: The Tricastin is a natural and historic region in the southern Rhône valley of southeastern France comprising the southwestern portion of the Drôme department and the northwestern portion of Vaucluse and centered on the modern town of Saint-Paul-Trois-Châteaux.
  The region is the cradle of the ancient Tricastini tribe, whose capital was Augusta Tricastinorum under Augustus's reign, now Saint-Paul-Trois-Châteaux.
  The name Tricastini, which for a long time was interpreted as meaning "the land of the Three Castles" in reality derives its name from the Gallic tribe the 'Tricastini', which occupied the territory during the Roman period.
  Nowadays, the Tricastin region is known as the site of the Tricastin Nuclear Power Plant situated on the Donzère-Mondragon canal, a tributary of the Rhône, for its Rhône valley AOC wine grape Grignan-Les Adhemar, and for its natural and architectural endowment.
context_section_description: The Tricastin truffle is protected by AOC certification since 1978, it ranges over 68 communes in the Drôme and 15 communes in the Vaucluse. In order to meet the AOC designation, the Tricastin truffle requires sterilization during the first boil and only with T. melanosporum.
  In this region, as in others, truffle growers got together and formed professional associations such as the Drôme des Collines or the Syndicat général de la truffe noire du Tricastin with headquarters at the Maison de la Truffe et du Tricastin in Saint Paul Trois Châteaux.
