“Oregon white truffles have this beautiful earthy, garlicky, blue cheese thing going on,” says Will Craigie, owner of Prestige Wine Tours, who leads the forages with his dog, Maeva. She’s a Lagotto Romagnolo, an Italian breed renowned for its truffle-hunting abilities; her training began when she was a newborn.

For an additional fee, foragers can end their one- to two-hour hunt with a meal and wine tasting at one of two local vineyards, Silas Wines or Bryn Mawr Vineyards.
