About Chalk Hill

A growing region tucked into the eastern edge of the Russian River Valley, Chalk Hill is small yet mighty. Far enough from the coast to ripen the hearty Bordeaux grape varieties of Cabernet Sauvignon, Merlot, Cabernet Franc, Malbec and Petit Verdot, Calluna is located in the path of the cold Petaluma Gap to keep the vineyard moderated from temperature extremes.

Calluna’s location on Chalk Hill gets the necessary warmth but is positioned with the important elevation needed to avoid temperature extremes and take advantage of those cooling Pacific Ocean breezes. The vineyard cools down sooner in the afternoon because of the elevation but most importantly has warmer nights than many areas because the cool air runs to the bottoms of the hills.

All of those factors: microclimate, elevation & soil structure work together to create a unique growing region that differentiates it from the surrounding Russian River Valley, Alexander Valley, Dry Creek Valley and Knights Valley.

Soils at Calluna: Clay-Loam underlain with fractured shale and sandstone.
