Mas Igneus operates in Priorat, the steep-terraced region of southern Catalunya known for powerful, mineral-driven wines from old vines. The winery's portfolio centers on Carignan and Garnacha—varieties that thrive in Priorat's slate-rich soils and demanding terrain. Coster de Carignan, a single-varietal expression, demonstrates the depth Carignan achieves in this appellation. Costers de Mas Igneus blends Garnacha and Cariñena, capturing the region's characteristic structure and earth-forward character. La Capelleta, a white wine from Grenache Blanc, offers a counterpoint to the region's red-wine reputation. The winery's wines have been assessed by Wine Advocate, Wine Spectator, and Wine Enthusiast.
