2020 vintage – 99% Sauvignon Blanc, 1% blend Viognier/Verdejo/Sémillon from grapes grown in top vineyards throughout Napa Valley, including our own estate ranches in Carneros, Suscol Springs, Rutherford, and Calistoga. The Sauvignon Blanc grapes are harvestd during the cool nighttime hours to fully capture their pure flavors and vibrant acidity. They are pressed as whole clusters under anaerobic – or oxygen-free – conditions. This maximizes varietal intensity while minimizing the extraction of astringency from the skins. 90% of the juice is fermented in stainless steel tanks, 6% in concrete eggs to soften acidity, and 4% in neutral French oak barrels. Following fermentation, the wine aged five months in neutral French oak barrels, with a small amount aging in concrete. Aging: 94% aged for 5 months in neutral French ok; 6% in concrete egg.
