Since 1981, the Bundschu family has crafted a limited bottling of the vintage's most elegant and expressive vines with the designation Vintage Reserve. Winemaker Keith Emerson selects individual barrels to blend a wine that showcases the distinctive character of Cabernet-family grapes grown on the southwest slopes of the Mayacamas Mountain Range. Our 150+ year old estate vineyard lies eight miles north of San Pablo Bay on steep, shallow soils of volcanic ash and tufa, exposed to pervasive maritime breezes, long daylight hours and extreme diurnal temperature shifts. Top blocks are farmed specifically for Vintage Reserve that yield 2.5 tons/acre. Lots sourced from other high elevation sites in Sonoma Valley add weight to the midpalate and a juicy component to the well-structured Cabernet Sauvignon from our cooler climate estate vineyard.
