Just 7 miles from the San Pablo Bay, the plantings of Cabernet Sauvignon by father-daughter team Dick and Allison Steltzner date back to 1976. 

The vineyard’s sandstone palisades and proximity to the Bay provide an ideal location for late ripening varietals such as Cabernet Sauvignon and Petit Verdot. Currently farmed meticulously by Jim Barbour, these vines are the unknown “Martini” clone, a fascinating clone of Cabernet Sauvignon that Dick Steltzner pulled from Louis Martini’s original estate that may only exist in this one location. With roots settled in volcanic sandstone, this mystery clone, in conjunction with the site’s terroir of heat reflective sandstone, and the Bay’s moderating influence allow us to create a wine of intrigue; balancing structure, and length.

Winemaker's Notes | In the glass, vibrant aromas of blueberry, tea leaf, and sandalwood greet you. On the palate, layers of tension turn into graceful depth. A subtle crème de cassis concludes the finish, allowing a reverence for sense of place.

Notes from the Growing Season | A dry, warm Winter preceded a cool Spring with heavier than average rainfall. Mild Spring conditions led to a late bud break, indicating the potential for a long growing season. Cooler than average, and stable conditions pushed into Summer with flowering beginning in late May and early June throughout the valley.

Protected by a consistently mild Summer, vines were not overstressed, allowing for fruit to mature delicately for optimum color and tannin development. On schedule for the season, veraison began in late July and early August.

Harvest began several days prior to the 2018 vintage with our Platt Vineyard Chardonnay mid-September. Our Cabernet Sauvignon harvest began in late September, and finally concluded in late October.

The typically hot, windy Fall season held to more temperate weather, accenting the long growing season, protecting fruit dehydration and sunburn. The excellent potential seen during the 2019 growing season was translated in the quality of wine of put to barrel. We look forward to sharing this vintage with the release of our 2019 single vineyard wines in Spring 2022.
