Il Passo works with Aglianico in Basilicata's Aglianico del Vulture zone, where volcanic soils shape the character of this southern Italian region. Aglianico is a dark-skinned variety with natural structure and aging potential, thriving in the cooler microclimates of the Vulture area. The winery's Alberi in Piano Aglianico del Vulture demonstrates the grape's mineral precision and tannin framework. Wine Advocate, Decanter, and Wine Spectator have assessed Il Passo's portfolio, reflecting the critical attention now directed toward Basilicata's volcanic terroirs and their distinctive expression of this ancient southern variety.
