The Spanish wine region in Catalonia famous for powerful Garnacha-based red wines is Priorat.
Priorat is a Denominació d'Origen Qualificada (DOQ) in Tarragona province, in southwestern Catalonia. Its vineyards grow on steep terraces and hillsides, where the distinctive black slate and quartz soil, called llicorella, drains water and encourages very low yields. Garnacha, known as Garnatxa in Catalan, is one of the region’s traditional red grapes, commonly blended with Cariñena and sometimes Cabernet Sauvignon, Merlot, or Syrah.
Priorat wines gained international attention during a quality revival in the 1990s. Winemakers including Álvaro Palacios helped demonstrate the potential of old, low-yielding vineyards, with L’Ermita becoming an especially influential example. Priorat became one of only two Spanish wine regions with the highest DOCa/DOQ classification, alongside Rioja.
A common mix-up is Montsant, the neighboring appellation that surrounds much of Priorat and can produce similarly intense reds. The comarca is called Priorat, while the wine designation is DOQ Priorat; the Castilian form Priorato also exists.
