Mastroberardino produces wines from Campania in Southern Italy, focusing on Aglianico—the region's signature dark grape. The winery's portfolio centers on expressions of this variety, from structured reserve bottlings to younger releases. Taurasi Riserva Cento Trenta and Taurasi Riserva Radici Antonio represent the upper tier, both Aglianico-based reserves that have been assessed by Wine Advocate, Wine Enthusiast, Wine Spectator, Falstaff, and Decanter. Stilema, also Aglianico, rounds out the core range. Aglianico from Campania is known for its depth, tannin structure, and ability to age, yielding wines with dark fruit, mineral tension, and earthy undertones. The winery's work with this varietal reflects the volcanic soils and continental climate that define the region's character.
