Hills to the west and east of the Stags Leap District allow the passage of special breezes from the bay into the interior of the region, making this small but renowned AVA slightly cooler at night than other area in the valley. The subtle climate variation and the appellation’s famously unique soils of old river sediments and heavy loamy clay, help provide for the low vigor vines and robust yet elegantly balanced wines of this District’s famed three square miles.
