Casa Gran del Siurana sits in Priorat, the steep-terraced region of southern Catalunya known for dense, mineral-driven reds. The winery works primarily with Cariñena, Garnacha, and Syrah—varieties that thrive in Priorat's schist soils and produce wines of structure and depth. Gran Cruor Selecció Caranyena, a single-varietal Cariñena, leads the portfolio and has drawn attention from Decanter, Wine Enthusiast, Wine Advocate, and Wine Spectator. The Priorat Cruor blends Cariñena, Garnacha, and Syrah into a more complex expression of the terroir, while Gran Cruor balances Syrah and Garnacha. These wines reflect the region's character: concentrated fruit, high acidity, and the distinctive slate minerality that defines Priorat's identity.
