Castillo de Aguarón is located in Cariñena, Aragón's historic wine region in northeastern Spain. The winery produces Garnacha, the dark-skinned grape that defines much of the region's character. Cariñena has long been known for robust, mineral-driven reds built on Garnacha's natural structure and depth. The region's continental climate and slate-rich soils shape wines of considerable weight and aging potential. Castillo de Aguarón's Garnacha has been assessed by Wine Advocate, reflecting the winery's standing among serious collectors and critics.
