Castrucci Vineyard: 
Perched on a hillside of fractured rock, and shrouded with morning fog and afternoon sea breezes, the Castrucci vineyard is like no other vineyard I've experienced.  At the southeastern mouth of the valley, it looks over the San Pablo Bay straight at the Golden Gate and the Pacific Ocean.  The rocky soil and western exposure drives ripening, but the cool climate maintains freshness and acidity. This results in wines with a lot of depth and character, but zesty mineral freshness.

Dead Fred Vineyard:
The Dead Fred Vineyard is in Coombsville, a volcanic valley east of the City of Napa, and just north of the Castrucci Vineyard.  Though not as cool climate as The Castrucci Vineyard, Coombsville is considered one of the coolest locations in the Napa Valley for Cabernet Sauvignon, and it performs best on soils with rock and plenty of sun.  The Dead Fred Vineyard is a perfect Coombsville location. Located on a knoll of rock and weathered volcanic ash, the vines pick up plenty of sun and heat, while maintaining vibrancy and balance.
