Dirupi produces Nebbiolo-based wines from Valtellina Superiore, the alpine region of Lombardia in northern Italy. The winery's portfolio centers on this demanding varietal, which thrives in the steep, sun-exposed vineyards of the Valtellina valley. The Gess Grumello Valtellina Superiore, the flagship expression, has been rated by Wine Advocate, Wine Spectator, and Wine Enthusiast. The core range includes the Valtellina Superiore and Vigna Riserva Valtellina Superiore, both Nebbiolo-based offerings that reflect the precision and structure characteristic of the region's high-altitude terroir. Valtellina's continental climate and granite-rich soils produce wines of mineral intensity and aging potential, qualities evident across Dirupi's lineup.
