Rocca del Principe operates in Campania, the southern Italian region where volcanic soils and Mediterranean climate shape distinctive wines. The winery focuses on indigenous varieties: Aglianico, the region's signature dark grape known for structure and aging potential, and Fiano, a white of mineral precision and complexity. Mater Domini Taurasi, an Aglianico expression, represents the winery's work with this noble varietal. Tognano Fiano di Avellino Riserva showcases the depth possible in the region's premier white designation. A second Aglianico offering, Aglianico Irpinia, rounds the portfolio. These wines have been assessed by Wine Enthusiast, Decanter, Wine Advocate, and Wine Spectator.
