Errazuriz operates in the Aconcagua Valley, a region defined by its continental climate and mineral-rich soils that shape wines of precision and depth. The winery's Las Pizarras range demonstrates the valley's capacity for cool-climate expression across three distinct varietals. The Chardonnay balances richness with acidity, the Pinot Noir captures the elegance characteristic of the region's cooler microclimates, and the Syrah expresses the darker fruit and structural complexity the valley supports. These wines have been assessed by Decanter, Wine Advocate, Wine Enthusiast, Wine Spectator, and Falstaff, reflecting their standing within the broader conversation around Chilean viticulture. The Aconcagua Valley's elevation and proximity to the Andes create conditions that favor both white and red varieties, allowing Errazuriz to work across a range of expressions rooted in terroir.
