More about the 2015 THE GRADE WINFIELD VINEYARD CALISTOGA CABERNET SAUVIGNON: The Grade’s 2015 Winfield Vineyard Cabernet Sauvignon is a wine that suspends time—a vivid reflection of Thomas Rivers Brown at the peak of his craft, delivering precision and soul in every glass. From the first sip, it awakens something profound. Concentrated yet refined, powerful yet balanced, it weaves tension and elegance with masterful finesse. The Winfield Vineyard, a 32-acre gem nestled along the historic Old Toll Road north of Calistoga, is where geography and geology unite. This elevated site, parsed into seven distinct parcels, thrives on dramatic diurnal shifts—warm, sun-drenched afternoons giving way to cool nighttime breezes. These conditions coax the fruit to ripen slowly, infusing each cluster with depth and character. In 2015, Thomas Rivers Brown chose three exceptional blocks to shape this singular wine. Now, with nearly a decade in the bottle, it has softened its youthful edges stepped fully into its grandeur. The tannins have smoothed to silk, the flavors have grown richer, and what emerges is a wine of striking grace and presence—a quiet celebration of Calistoga’s strength and Brown’s enduring brilliance.
