"Some of Tuscany's greatest treasures aren't found in vineyards or castles. They're hidden beneath the forest floor, waiting for the nose of a remarkable dog to uncover them." Most visitors arrive in Tuscany dreaming about wine. I certainly did. Brunello. Chianti Classico. Vernaccia. Vino Nobile. I thought I understood Tuscany because I had spent my days wandering vineyards and tasting incredible wines.
