In 2002, Valeria and Agustin Huneeus' dream of the Quintessential Wine Estate, one vineyard that produces one singular estate wine, was realized with the opening of the winery at Quintessa. Walker Warner Architects of San Francisco designed the winery to reflect Agustin and Valeria Huneeus' desire for an inconspicuous structure that would blend into the contours of the property. The graceful crescent-shaped design was carefully considered for its environmental sensitivity and fits snugly into an eastern-facing hillside, disrupting little in the way of the aesthetics or natural beauty of the property. A facade of indigenous stone and natural landscaping of native plants and oak trees creates a subtle presence amidst the diverse terrain.
Quintessa is truly a "winemaker's winery. The design facilitates a gravity-flow process and a state-of-the-art winery specifically tailored with fermenters and tanks sized to match the diverse blocks in the Quintessa vineyard. Additionally, the winery at Quintessa is outfitted with the latest in winemaking technology. French oak and stainless steel fermenters stand tall along the winery's front wall, providing the winemaking team with a choice of characteristics adding complexity and subtlety to the blend. Two Vaslin-Bucher JLB automated basket presses, designed for Quintessa to retain the benefits of gentle basket pressing while incorporating new efficiency and precision, are ideally situated at the center of the tank room to receive the grape must following fermentation and maceration. At the heart of the winery and overlooking the tanks and presses below, sits the glass-enclosed blending room and adjoining modern lab where the winemaking progress is painstakingly monitored daily.
Behind the press hall lies the main entrance to Quintessa's caves structure, 1,200 linear feet, and 17,000 square feet of caves and tunnels carved into the volcanic ash hillside directly behind the winery. Here the wine is left to age in French oak barrels in the caves' ideal cellarage conditions for three years from vintage before its release. Quintessa's caves can be entered through one of four porticos from the winery and have a capacity to store up to 3000 barrels.
