B.R.V., Stag's Leap's estate vineyard bordering the Napa River in the Oak Knoll District, contributes more than 40% of the fruit to this blend. In these fertile soils, they control vigour through proper crop loading, trellising, and canopy management to coax out the fruity and floral characteristics of the varietal while limiting its more aggressive herb and grass elements to delicate top notes. B.R.V. is planted in part with Sauvignon Musque, a clonal variant originally from Bordeaux, prized for its intense floral and tropical fruit flavours. It accounts for over a quarter of the blend. Then, they balance the round fruit flavours of B.R.V. with the more structured mineral and citrus character of the grapes from Terrence Wilson’s Rancho Chimiles Vineyard in Wooden Valley. They continue to build complexity with the addition of Semillon, known for its honey, fig, and melon character. The winemaking team preserves the wine’s sleek varietal character by tank fermenting half of the grapes, while sur lies aging (leaving the wine in contact with the spent yeast) in third- and fourth-fill French oak and regular battonage (stirring the lees) smooth out any edges and give the wine an appealing texture.
