De Muller produces wines from Tarragona, in southern Catalunya, where Mediterranean warmth and coastal influences shape the character of the region's vineyards. The winery's portfolio centers on both classic varietals and regional expressions. Les Pusses Merlot - Syrah blends Merlot with Syrah to create a wine of structure and depth, while a Chardonnay offers the variety's signature balance of richness and acidity. T7 Set De Negre Tarragona rounds out the range as a regional red wine. These wines have been assessed by major critics including Wine Spectator, Wine Enthusiast, Wine Advocate, Falstaff, and Decanter, reflecting the winery's standing within the broader wine conversation. Tarragona's warm climate and established winemaking tradition provide the foundation for De Muller's approach to both international varieties and locally rooted styles.
