Puerto Viejo is situated in Curicó Valley, the southern reach of Chile's Central Valley. The region's cool-climate conditions and mineral-rich soils shape wines of clarity and precision. The winery's Reserve Sauvignon Blanc demonstrates the potential of the valley's terroir—a wine that has drawn attention from major critics including Wine Advocate, Wine Enthusiast, Wine Spectator, and Falstaff. Sauvignon Blanc thrives in Curicó's conditions, developing the aromatic intensity and crisp acidity the variety is prized for. Puerto Viejo's focus on this varietal reflects both regional strength and a commitment to expression through a single, well-defined wine.
