Jackson Family Wines has achieved Regenerative Organic Certified status across its Napa Valley estate vineyards, the company announced in September 2026. The certification covers approximately 663 acres, making the company the largest ROC grower in Napa Valley and roughly doubling the valley's total certified regenerative organic vineyard acreage.
The recognition applies to the vineyards rather than the winery or finished wines, spanning growing areas including Oakville, Rutherford, and Howell Mountain. Fruit from the certified vineyards feeds some of the company's most prominent labels, including Cardinale, Mt. Brave, and Freemark Abbey.
The certification caps a multi-year conversion. The same vineyards earned organic certification in autumn 2023 through California Certified Organic Farmers, after the company implemented cover cropping, no-till management, compost and biochar applications, sheep grazing, and integrated pest management including owl boxes and beneficial insects. The formal ROC process began in 2024, and the company has set a goal of farming all of its vineyards regeneratively by 2030.
For shoppers, the certification applies to the vineyards rather than the bottle, so it will not appear as a wine label claim. But it gives the valley's largest family-owned wine company a verifiable credential at a moment when regenerative language faces growing scrutiny from consumers and the trade.
The announcement lands as regenerative claims face growing scrutiny from consumers and the trade, and a certification at this scale gives the valley's largest family-owned wine company a verifiable credential. With harvest underway across Napa Valley, the 2026 vintage will be among the first to include ROC-certified fruit from these estates.
