St Amant Winery

What St Amant Winery does

St. Amant Winery is a privately held, family-owned winery founded in 1981 by Tim Spencer in Amador County, California, and now operating from the Lodi Wine and Business Complex in Lodi. The winery's defining proposition is its pioneering role in planting and crafting wines from Portuguese and Spanish (Iberian) grape varieties — including Bastardo/Trousseau, Touriga Nacional, Touriga Franca, Tinta Cao, Souzão, Tempranillo, and Verdelho — alongside California heritage varieties such as Old Vine Zinfandel, Barbera, Petite Sirah, and Alicante Bouschet. Production is small-lot and minimal-intervention, with twenty-plus wines released annually, many in very limited quantities. The winery draws fruit from its own 43-acre Spencer Ranch in Amador County (15 blocks of 9 varieties) and from long-standing partnerships with Mohr-Fry Ranches (Marian's Vineyard, planted 1901), Leventini Vineyard, Shinn Farms, and Lloyd Martel Vineyard.

The commercial model is direct-to-consumer across three channels: an e-commerce store shipping to 43 U.S. states, a tasting room at 1 Winemaster Way in Lodi (Thursday–Monday, 11AM–4PM), and two wine clubs. The St. Amant Wine Club operates a customizable subscription with three annual releases (February, May, October) at 4-, 6-, and 12-bottle tiers (~$100/~$150/~$300 per release), with a 20% discount and free shipping on case orders. The Bastardo Society is an exclusive port-focused club with two shipments per year (April and December) at $150 per release, featuring three small-lot port wines each. Pricing uses credit card (Visa/MasterCard) only, with no minimum purchase; shipping is handled via Federal Express Ground.

The customer base is segmented across discerning wine enthusiasts seeking heritage and old-vine wines, port and fortified wine lovers, and explorers of obscure Iberian varieties. The winery has built reputational equity through three "Best Red Wine of Show" honors at the California State Fair in ten years (2016, 2018, 2025), 2025 Vineyard of the Year for Marian's Vineyard, a VinePair Best Value Red Blend award, and a 2026 "Leader of the Year" recognition for winemaker Stuart Spencer. Certifications include LODI RULES for Sustainable Winegrowing (since 2005/2012). The business has no external institutional investors, no parent company, and operates with a small core team led by Stuart Spencer (winemaker), Nathan Haberkern (General Manager), Will Delgado (Cellar Hand), with co-founder Barbara St. Amant Spencer still active in the tasting room at 83 years old.
