Frog's Leap Winery

Frog's Leap was founded in 1981 by John Williams and Larry Turley on a property that had previously been used as a frog farm, providing the winery its name and enduring sense of humor. Williams came to the project with firsthand experience at Stag's Leap Wine Cellars, where he had helped bottle the celebrated 1973 Cabernet Sauvignon that triumphed at the 1976 Paris Tasting, and later worked at Spring Mountain. The first vintage produced just 450 cases of Sauvignon Blanc and 350 cases of Zinfandel from leased land. In 1994, the winery relocated to its current home, the Red Barn estate in Rutherford, a property centered on a building originally constructed in 1884 as the Adamson Winery. That same decade, Williams had already set the winery apart by earning CCOF organic certification for its vineyards in 1989, making Frog's Leap the first certified organic vineyard in Napa Valley.

• Founded 1981 on a former frog farm; first wines were 450 cases Sauvignon Blanc and 350 cases Zinfandel
• John Williams previously worked at Stag's Leap Wine Cellars and helped bottle the 1973 Cabernet that won the 1976 Paris Tasting
• Winery moved to the historic 1884 Red Barn site in Rutherford in 1994
• CCOF vineyard certification achieved 1989, making it the first certified organic vineyard in Napa Valley

Larry Turley departed the partnership in 1993 to found Turley Wine Cellars, leaving John Williams as sole owner. Williams has remained actively involved in winemaking through 2024 and 2025, with the winery now transitioning toward the next generation. Rory Williams, born in 1984 and John's son, joined the operation in 2012 and was appointed Vice President of Viticulture and Enology and Director of Winemaking in 2021. His first independently led wine, the Flycatcher California red blend, was released in May 2024. Tori Williams serves as Managing Director overseeing farm operations and sustainability initiatives, while Pablo Polanco works as production winemaker. The family describes their approach as multigenerational, with Rory openly discussing climate resilience and long-term vineyard stewardship in public forums.

• Larry Turley exited in 1993; John Williams has been sole owner since then
• Rory Williams (VP of Viticulture and Enology since 2021) launched the Flycatcher red blend in 2024 as his first wine
• Tori Williams serves as Managing Director with a focus on farm operations and sustainability
• Pablo Polanco serves as production winemaker alongside the Williams family team

Frog's Leap farms approximately 200 acres in total, including owned and long-term leased or contracted vineyards spread across Rutherford, St. Helena, and Carneros. The Rutherford estate covers 40 acres around the Red Barn and has supplied the estate Cabernet Sauvignon since the 2000 vintage. Rossi Ranch, a 52-acre block on the Rutherford Bench acquired in 2007, was placed under a conservation easement in 2011 and is the source of the Williams Rossi reserve Cabernet, first released in 2020. A Zinfandel vineyard in St. Helena and sourced Chardonnay from Truchard Vineyard in Carneros round out the main holdings. All estate vineyards are dry-farmed without artificial irrigation, a practice the winery argues produces more stress-resilient vines with deeper root systems.

• Rutherford estate: 40 acres around the Red Barn, source of the estate Cabernet Sauvignon since 2000
• Rossi Ranch: 52 acres on the Rutherford Bench, acquired 2007, conservation easement placed 2011
• Chardonnay sourced from Truchard Vineyard in Carneros for the Shale and Stone bottling
• All estate vineyards are 100% dry-farmed with no artificial irrigation

Frog's Leap operates under CCOF certified organic principles across its vineyards and winery, with full winery certification achieved in 2002 and biodynamic-influenced practices layered on top. Fermentations rely on natural yeasts, sulfur additions are kept minimal, and oak is used for elevage rather than as a source of flavor. The dry-farming philosophy is central to the house style: Williams has long argued that irrigation-dependent vines produce fruit with less character and that deep-rooted, drought-adapted plants make more honest wine. The winery achieved LEED certification for its hospitality building, holds Napa Green certification, and in 2025 added both IWCA Silver Certification from the International Wineries for Climate Action and TRUE Zero Waste Silver Certification. Even the branded Ribbit corks reflect the winery's view that wine should be welcoming rather than intimidating.

• CCOF certified organic winery since 2002; vineyard certification dates to 1989
• Natural yeast fermentations and minimal sulfur dioxide; oak used for structure rather than flavor
• Napa Green certified, IWCA Silver Certified (2025), and TRUE Zero Waste Silver Certified (2025)
• LEED-certified hospitality building on the Rutherford estate

Frog's Leap occupies a distinctive position in Napa Valley as the region's longest-standing certified organic producer and a consistent advocate for dry farming at a time when both practices were marginal rather than mainstream. The winery demonstrated early that organic viticulture and commercial scale were compatible, producing 50,000 to 65,000 cases per year without abandoning its principles. Its Sauvignon Blanc has appeared in every single vintage since 1981, offering a counter-narrative to the idea that Napa is only about Cabernet. The ongoing generational transfer from John to Rory Williams keeps the founding philosophy intact while adding fresh thinking on climate adaptation and low-intervention farming. For students of American wine, Frog's Leap is a case study in how a small-production idea can scale without losing its identity.

• First CCOF-certified organic vineyard in Napa Valley (1989); full winery certification 2002
• Sauvignon Blanc produced every single vintage since the winery's founding in 1981
• Production of 50,000 to 65,000 cases demonstrates organic farming at commercial Napa scale
• Conservation easement on Rossi Ranch (2011) reflects long-term commitment to land stewardship over short-term development value
