Douglas and Mary Day

Proprietors



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.
