Napa County's Board of Supervisors spent an August hearing weighing the near-term fixes its wine industry wants — looser signage rules, fewer zoning hearings, bigger micro-winery caps — while deferring the harder rewrite everyone kept circling back to: on land a 1968 voter measure set aside for farming, where does agriculture end and a commercial venue begin?

The 1990 Winery Definition Ordinance dictates what Napa's wineries may do — how much they produce, how many visitors they see, which experiences they can sell — on land protected by an agricultural preserve voters created in 1968. Facing an industry downturn, Napa's largest farm and wine groups have asked the county for nearly two dozen changes. The quick administrative fixes have broad support. The unsettled question is whether to reopen the ordinance itself, and that is a land-use fight, not a wine one.

The push became formal on April 10, when four organizations that don't always march together — Napa Valley Vintners, the Napa Valley Grapegrowers, the Napa County Farm Bureau and Winegrowers of Napa County — handed supervisors 23 joint recommendations. As the North Bay Business Journal reported (external source, opens in a new tab), the coalition sorted its asks into fast administrative tweaks and heavier policy tied to the county's coming General Plan update. Michelle Novi, an industry-relations director at Napa Valley Vintners, told the outlet the near-term items would leave the ordinance untouched. "It's not 1990 anymore," she said. The industry values agriculture's yearly contribution to the county at more than $11.7 billion.

The board took up the short list Aug. 11 in a session the Napa Valley Register described (external source, opens in a new tab) as resembling a "State of Wine Country" summit. On the table: dropping the "by appointment only" signage rule for wineries permitted after 1990, skipping some zoning-administrator hearings unless a neighbor objects, and enlarging the micro-winery category — potentially lifting the annual production cap from 5,000 to 10,000 gallons and doubling permitted daily car trips from 20 to 40. Some items are tiny; wineries might no longer need a permit to bolt in a bike rack. Supervisor Anne Cottrell backed simplification but wanted a trade: the more tangled the county's rules grow, she said, the harder compliance is to track — so she pressed wineries seeking changes to meter their wells in exchange.

The friction lives in the bigger question of rewriting the ordinance, which the board left for another day. Debra Dommen of Treasury Wine Estates told the board Napa has demonized the word "commercial," citing a winery yoga-and-tasting session the county shut down. Farmland here has never been a public park, she argued, but a business that has to earn its keep. "The ag lands have always been commercial," she said.

Board Chair Amber Manfree pulled the discussion back to the 1968 preserve, warning that if agriculture stops being the county's defining use, Napa has an identity problem. "If yoga is agriculture, I'm sure weddings are too," she said — weddings are barred at most wineries in the unincorporated county. Supervisor Joelle Gallagher agreed the county has to preserve the link between growing grapes and hosting guests, or risk blowing the preserve apart entirely.

Growers insisted that is exactly what they are protecting. Michelle Benvenuto, from the Winegrowers of Napa County, said the coalition isn't chasing agritourism — no hotels, no restaurants on winery parcels — only leeway to run existing wineries more practically with current protections intact. Robin Baggett of Alpha Omega Winery went further, questioning why the county caps the staffing and visitor numbers his fire marshal would otherwise allow.

Environmental and small-farm voices pushed the other way. Yvonne Baginski of the Napa County Wildlife Conservation Coalition countered that the valley is already a monoculture that has wiped out habitat for birds and mammals. Elise Nerlove of the Micro-Winery Guild, which fought for the county's 2022 micro-winery law, warned that raising its ceilings only rewards scale: "The message here is still 'Go big or go home.'"

For now, the incremental fixes look likely to advance by year's end while the ordinance stays closed. The county is also running an 18-month pilot for outdoor "estate tasting events" under state Assembly Bill 720, effective Jan. 1 and set to expire July 1, 2027 (external source, opens in a new tab) unless supervisors extend it — and the industry wants it widened to winery-owned vineyards. Each loosening is defensible alone. Napa's harder task is deciding, in aggregate, what still counts as farming on land it set aside decades ago to keep from becoming something else.
