Celler Vall Llach is a boutique winery based in the village of Porrera, in the prestigious DOQ Priorat region, known for its strong focus on terroir and small-scale, high-quality wine production. It was founded in the 1990s as a joint project of Catalan musician and writer Lluís Llach and winemaker Enric Costa, with the idea that winemaking could contribute to the revitalization of the local community.
