Estate Grown. Hanna's 252 acres of estate vineyards are located in three of Sonoma's finest Appellations. These exceptional vineyards allow us to craft wines of consistently high quality year after year. At Hanna we incorporate a hands-on family approach to every aspect of our winemaking process, using superior quality fruit grown at our Sonoma County estate vineyards. The Russian River Valley's cool climate allows slow ripening and gives this wine its lively fruit aromas, crisp flavors and broad finish.
