General Information

Perched on a rocky outpost high above the city of Napa, Heron Lake catches the cool breeze coming off San Pablo bay as it rises up into the Vaca Mountains. The vines are planted in extremely shallow volcanic soils, where formations of quartz, granite and feldspar frequently rise to within just a few inches of the surface. The intersection of this coastal climate and rugged soil profile creates wines that express a daring combination of freshness, acidity, depth and texture, along with the vineyard’s signature chunky “white quartz” minerality.


Heron Lake is farmed organically under the watchful eye of David Mahaffey who has managed the site since it was first planted in 1980. David was the first person to hire me in the wine business and has been a friend and mentor ever since.
