Vineyard Sources

We source our grapes from several vineyards within the Paso Robles AVA and produce our wine at Cass Vineyard. We are inspired by the focus on their low yield, premium quality fruit as well as the impeccable care of their vineyards. Together, we share a love of the environment and promote sustainability of nature’s resources.


Cass Vineyard

Appelation: Geneseo District AVA
Named 2015 Winery of the Year from the Central Coast Wine Competition

Cass Vineyard is located in the rolling, oak-studded hills between Paso Robles and Creston on California’s beautiful Central Coast. Due east of the “Templeton Gap”, Cass Vineyard receives the evening’s cooling breezes that the west side of Paso Robles is noted for. The vineyard is an ideal distance from the coast to generate the heat needed to optimally ripen the premium Rhône varieties grown on the 145-acre rolling hill estate.

A unique feature of Cass Vineyard is that all of the Rhône grapes grown at the vineyard are ENTAV certified. ENTAV (Establissement National Technique pour l’Amelioration de la Viticulture) is the national agency of France responsible for the quality of wine grape varieties. Over 90% of all French Vineyards are started with ENTAV certified plants and where only recently available in California. Consequently, these are among the very first first wines made from ENTAV grapes grown here. 

Cass Vineyard is also a certified sustainably farmed vineyard through SIP Certification. While many consumers are dedicated to looking for wines labeled as “green wine” or “organic wine,” SIP Certification is a unique combination beyond those two labels. Imagine a wine that builds community between vineyards, workers and the land. 

Fruit Sourced: All red varietals, Viognier, Marsanne & Roussanne.


Alta Colina Vineyard

Appelation: Templeton Gap AVA

Owned and farmed by the Tillman Family, Alta Colina is a unique, high-elevation site in the Templeton Gap that spans from 1600 - 1780 feet above sea level. Planted mostly to a suite of Rhone varietals, the site is composed of predominantly calcareous and loam-based soils that are high in drainage, encouraging vine vigor. The property is farmed with minimal inference, typically seeing only 4 passes each vintage for shoot thinning, canopy adjustments and fertilization. Its proximity to the Pacific Ocean sees cool morning and afternoon fog on the property, that helps facilitate a long growing season, ideal for the ripening of fruit.

Fruit Sourced: Grenache Blanc


Castoro Cellars

Appelation: Paso Robles AVA

Castoro Cellars sources grapes almost exclusively from their Estate Grown, sustainably farmed vineyards. Nearly all of their fruit comes from within the Paso Robles AVA. They select their grape sources carefully, matching vineyard location with the grape variety that thrives in that particular setting and employing vineyard techniques that produce the desired characteristics of each varietal. All Castoro’s estate grown vineyards employ sustainable viticulture practices. They have over 350 acres of "Certified Organic" estate grown vineyards (with additional acres pending), by the California Certified Organic Farmers (CCOF) in compliance with USDA standards. Their vineyards are also SIP Certified.

Fruit Sourced: Chardonnay
