I Vigneri produces wines from Terre Siciliane in Southern Italy, drawing on indigenous varieties that define the region's character. The winery focuses on white wines built from grapes native to Sicily: Carricante and Grecanico. Palmento Caselle, a Carricante, stands as the flagship expression, joined by Vigna di Milo Caselle, also Carricante, and Vinudilice, made from Grecanico. These wines have been assessed by Decanter, Wine Spectator, Wine Advocate, and Wine Enthusiast. Carricante and Grecanico are mineral-driven varieties with natural acidity, well-suited to Sicily's volcanic soils and Mediterranean climate. The wines reflect the precision and freshness characteristic of Southern Italian white wine production.
