Valley, Sonoma Valley and Lake County. Alexander Valley fruit provides a core of citrus and juicy tropical fruit flavors. The high elevation volcanic soils of Lake County contribute pretty floral notes and the Sonoma Valley grapes boast distinct mineral nuances. To capture the varietal’s aromatic qualities, the wine is fermented and finished in stainless steel. Dramatic style, vibrant packaging and fruit-forward, smooth wines are the signatures of Francis Coppola Diamond Collection. Our Sauvignon Blanc delivers a beautiful perfume of tangerine, pink grapefruit, and honeysuckle, followed by juicy flavors of tropical fruit, zesty citrus, and a hint of minerals.
