Castello di Amorosa vineyards are in the heart of the Diamond Mountain District, a nested American Viticultural Area (AVA) within the Napa Valley. Located east of highway 29 and just 3 miles south of the city of Calistoga, our 30 acres of vineyards surrounding the Castello are planted to Cabernet Sauvignon, Merlot, Sangiovese and Primitivo.
Wine grapes, particularly Cabernet Sauvignon, are the true diamonds of this remarkable AVA. Covering 5,000 rocky acres in the Mayacamas Range on the northeast side of Napa Valley, this region has just over 500 acres under vine. Due to the up-valley location and the high elevation of vineyards, the fog that influences the valley floor is not a factor here. Our vineyards possess unique, porous volcanic soils. With vineyards high above the fog and facing west, Castello di Amorosa’s wine grapes receive an extended exposure to the sun assuring their full ripeness at harvest. Castello di Amorosa’s Cabernet Sauvignon wines and the Cabernets of this AVA are described as rich and powerful with chewy textures and diamond-hard tannins.
