Sinegal Estate Winery

What Sinegal Estate Winery does

Sinegal Estate Winery is a Napa Valley producer of ultra-premium wines operating from a 30-acre heritage estate at 2125 Inglewood Ave in St. Helena, California, at the base of the Mayacamas Range. Founded in 2013 by David Sinegal and family on a property whose vineyard dates to 1881 (formerly The Inglewood Estate), the winery produces red wines (Napa and Sonoma Cabernet Sauvignon, Pinot Noir, the 2023 Wildwood Vineyard 100-year-old Zinfandel), white wines (Sauvignon Blanc, Rosé of Grenache), and a lower-priced sub-brand called Details by Sinegal in boxed and canned formats. Production relies on a documented 1,403-step field-first micro-farming and fermenting process, science-forward grape quality testing, and 100% solar-powered off-grid operations backed by CCOF organic and Fish Friendly Farming certifications. The company is privately held under David James, LLC, with no external institutional investors identified.

The business model is a hybrid direct-to-consumer and wholesale operation. Revenue is generated through e-commerce wine sales on sinegalestate.com (shipping limited to authorized US states), a four-tier wine club (Silver Key, Gold Key, Platinum Key, Master Key) delivering 4 to 24 bottles three times per year at $508-$2,574 per shipment, reservation-only estate tastings priced at $150 per person (refunded with qualifying purchases), private event venue rentals at the estate, corporate gifting concierge services, and wholesale distribution through regional division managers (including Midwest coverage) and on-premise national accounts. Hotel partnerships with Hotel Yountville and Bardessono provide lodging discounts for visitors.

The company targets affluent luxury wine consumers and wine club members as primary segments, with secondary segments in corporate gifting clients and private event hosts. Marketing spans content/journal, email, SMS, Instagram, signature estate events (Harvest Party, Summer Pre-Funk, lakeside gatherings), external wine event participation (BottleRock, Artisans Wine & Food, Rodeo Uncorked), and earned media in outlets including Bloomberg, Wall Street Journal, Wine Spectator, and Condé Nast Traveler. Operations are run by a small team of 1-10 employees led by Vintner and General Manager David Sinegal, Director of Winemaking Nick Moraida, Director of Membership Gardinia Gardner, Director of Hospitality Doug, Midwest Wholesale Division Manager Ashlie, and Assistant Winemakers Alanna Robinson and Janey Chritton.
