the SINGLE
VINEYARD SERIES

From the renowned vineyards like Gap’s Crown Vineyard within the Sonoma Coast to Keefer Ranch in Russian River Valley, we have come to understand each distinct set of soils, slopes, aspects, and microclimates of our Single Vineyard Grower Series designates. These limited production wines showcase Pinot Noir and Chardonnay in a truly special way, allowing the character of each site, and their unique sense of place to shine.

FEATURED RELEASED WINES

A Testament to Precision and Craft

4-Barrel

4-Barrel Pinot Noir is the purest reflection of our winemaking philosophy—an uncompromising pursuit of balance, complexity, and depth. Made as a thank-you to our members, this wine is the most limited in our portfolio, yet demands the greatest attention to detail.

Each year, we taste through our most compelling barrels, selecting just four that capture something truly exceptional. Unbound by vineyard or appellation, 4-Barrel allows us to craft a singular expression of Pinot Noir—one that embodies purity, intensity, and elegance.


Fermented in a mix of concrete and oak with carefully managed whole-cluster inclusion, then aged to achieve its signature refinement, this wine exudes remarkable aromatics, layered intensity, and a long, resonant finish. With fewer than 100 cases produced annually, securing an allocation is no small feat—our members typically wait over a decade for guaranteed access.


A rare and enduring tribute to our dedication to Pinot Noir, 4-Barrel remains one of the most sought-after wines in our collection.
