Collefrisio produces wines from Abruzzo, the rugged region of Central Italy where Montepulciano thrives on challenging terrain. The winery's portfolio centers on this dark, structured grape—the backbone of the region—alongside Passerina, the crisp white varietal native to the area. Eo Frisio Montepulciano d'Abruzzo and Uno Montepulciano d'Abruzzo represent the winery's interpretation of the region's signature red, while Passerina Terre di Chieti captures the mineral, aromatic character of the local white. Wine Enthusiast and Wine Spectator have rated these wines, reflecting their technical merit and regional authenticity. Collefrisio's focus remains on the grapes and terroir that define Abruzzo's winemaking identity.
