Hand-selected grapes from our prestigious Amador vineyards comprise the Terra d’Oro Amador County Zinfandel, the winery’s flagship wine. With 93% of the grapes sourced from our own estate vineyards, shallow topsoils, granite hardpan, hot summer days and cool summer nights make a remarkable home for the winemaker’s favorite varietal. Head-trained and spur-pruned, the Terra d’Oro vineyards receive optimal sunlight and deliver a controlled crop.
