The tropical fruit flavor of guava and papaya are derived from Silver Oak Oakville and Calistoga estate vineyards, while fresh, crisp minerality is a classic Sonoma County expression of the grape. In the cellar, the Estate keeps each Sauvignon Blanc vineyard lot separate and use a variety of fermentation vessels-from stainless steel barrels to concrete eggs and neutral oak-to add depth and richness to the wine. When these unique lots are blended together, the result is a complex and nuanced Sauvignon Blanc that delights the palate.
