Douglas and Mary Day


Hanzell Douglas Mary Day Sonoma

When Ambassador Zellerbach died in 1963, Hana Zellerbach sold the bottled and barreled wine inventories, much of it to Heitz Cellars; the 1961 and 1962 vintages of Heitz Chardonnay and Pinot Noir are indeed Hanzell-grown and produced. In 1965, Hana Zellerbach sold the estate to Douglas and Mary Day, who would expand Hanzell Vineyards modestly under their 10-year proprietorship. Mary Day, also a member of the La Confrérie des Chevaliers du Tastevin of Burgundy, hired Bob Sessions as Winemaker, and oversaw the installation of four and a half acres of new vineyards.
