Tudernum produces wines from Umbria, a region in central Italy known for structured reds and distinctive indigenous varieties. The winery works primarily with Sagrantino, a grape native to the Montefalco area that yields dense, tannic wines built for aging, alongside Merlot. Fidenzio Montefalco Sagrantino and Montefalco Sagrantino represent the winery's focus on this regional signature varietal, while Todi Merlot demonstrates work with the international classic. These wines have been assessed by Wine Enthusiast, Wine Advocate, and Wine Spectator.
