California Wine Regions for Vineyard Buyers: Beyond Napa and Sonoma
Vineyards for sale in California are spread across dozens of federally recognized wine regions, and outside Napa and Sonoma the main markets for Northern California buyers are Mendocino, Lake County, Solano’s Suisun Valley, the Livermore Valley, the Santa Cruz Mountains, Monterey, the Delta around Clarksburg and Lodi, and the Sierra Foothills. What a vineyard is worth in each depends largely on what its grapes sell for, and that varies widely: in 2025 Napa County grapes averaged $6,635.85 a ton, Sonoma and Marin $2,762.88, and the state as a whole $977.76.
This guide compares those regions for a buyer: the American Viticultural Areas (AVAs) in each, how much fruit each crush district produces, and what to check on the county and water side. Napa and Sonoma have their own detailed guides, linked below, and our vineyard and winery hub covers the North Coast market; this page is about the rest of Northern and Central California.
What an AVA tells you, and what it doesn’t
An AVA is a federal wine-labeling boundary defined in 27 CFR part 9. To put an AVA name on a label, at least 85% of the wine must come from grapes grown inside that AVA; a county name requires at least 75% from that county. An established name can add value to the fruit, which is why buyers start with the map.
An AVA isn’t a zoning district, though. A vineyard inside a well-known AVA is still governed by its county’s agricultural zoning, winery rules, grading and water regulations, and those differ more from county to county than the wine does. Grape prices are reported by crush district, which follows county lines, not AVA lines. Use all three: the AVA for the fruit’s reputation, the county for what you can build and operate, and the crush district for price benchmarks.
The 2026 market across California
The wine grape market is in a downturn, and that shapes every region below.
- Smaller crush, lower prices. California crushed 2,761,914 tons in 2025, down 6.1% from 2024, according to the final Grape Crush Report released April 30, 2026. Red wine grapes averaged $1,280.66 a ton and white wine grapes $706.10.
- Vineyards coming out. A mapping study for the California Association of Winegrape Growers found nearly 40,000 acres removed between October 2024 and August 2025, about 7% of the state’s winegrape acreage. Its 2026 update counted 47,229 acres removed between August 2025 and August 2026, leaving 439,115 standing acres.
- Land values under pressure. AgWest Farm Credit’s February 2026 land values report described declining values for premium Central Coast wine grape vineyards, citing weak wine demand.
For a buyer, that means more vineyards on the market and more room to negotiate, but also a bigger gap between a vineyard with a long-term grape contract and one selling fruit on the spot market. Price the income you can document, not the income a vineyard earned before 2023.

The North Coast beyond Napa and Sonoma
Mendocino County
Mendocino’s best-known vineyard area is the Anderson Valley, which federal rules place in the western part of the county, with a boundary that follows branches of the Navarro River and Greenwood Creek; it was recognized in 1983. The county also has inland AVAs, including Redwood Valley and Potter Valley, as well as Yorkville Highlands and Mendocino Ridge. Coastal and inland Mendocino are different markets with different permit rules, so start with our Mendocino County guide.
Lake County
Lake County’s vineyards center on Clear Lake. The Clear Lake AVA covers the southwestern part of the county, and the Red Hills Lake County AVA, on the lake’s southwestern shore between Lower Lake and Kelseyville, lies entirely inside it. The county’s other AVAs include High Valley, Big Valley District, Kelsey Bench, Upper Lake Valley, Long Valley, Guenoc Valley and Benmore Valley. Our Lake County vineyard and land guide covers zoning, water and fire there.
Solano County: Suisun Valley
The Suisun Valley AVA, recognized in 1982, runs from Cordelia northeast past Fairfield, and its northern edge follows the Napa County line. That proximity to Napa is the main draw for buyers; county rules are Solano’s, not Napa’s. Our Solano County guide covers the county side.
The Bay Area and Central Coast
Livermore Valley
The Livermore Valley AVA, recognized in 1982, covers parts of Alameda and Contra Costa counties. Outside the city, rural land in unincorporated Alameda County comes with its own voter-approved limits on development. Our Livermore Valley vineyard guide explains Measure D and the South Livermore Valley Area Plan.
Santa Cruz Mountains
The Santa Cruz Mountains AVA, one of the state’s older appellations (1981), spans parts of San Mateo, Santa Clara and Santa Cruz counties, and its boundary follows the 400-, 600- and 800-foot elevation contours in places. On mountain parcels like these, access roads, fire exposure and grading rules can matter as much as the vines.
Monterey County
Monterey is a large-volume district: 163,141 tons were crushed there and in San Benito County in 2025. The Santa Lucia Highlands AVA, recognized in 1992, has a boundary defined partly by elevation contours, and the boundary of the Arroyo Seco AVA (1983) begins where Jamesburg Road meets Arroyo Seco Road. Water use and groundwater plans are central to any Salinas Valley purchase; see our page on Monterey County water use and property plans.
The Delta, Lodi and the Sierra Foothills
Clarksburg
The Clarksburg AVA, recognized in 1984, is in the Sacramento River delta, with a boundary that follows the Sacramento River Deep Water Ship Channel, Miner and Cache sloughs and the Sacramento River. Delta vineyards raise questions upland ones don’t: levees, reclamation district assessments and flood risk. Our guide to Delta land and homes covers them.
Lodi
Lodi is the largest district on this list by volume: 532,409 tons were crushed in District 11 in 2025. The Lodi AVA, recognized in 1986, covers parts of Sacramento and San Joaquin counties. Lodi has also seen heavy vineyard removal; the 2025 mapping study reported nearly 8,000 acres removed in San Joaquin County alone. Diamond works in Sacramento County; for property on the San Joaquin side we can refer you to a local broker.
Sierra Foothills
The Sierra Foothills AVA, recognized in 1987, stretches across parts of Yuba, Nevada, Placer, El Dorado, Amador, Calaveras, Tuolumne and Mariposa counties. Inside it, the El Dorado AVA is bounded by forks of the American River, the Rubicon River and the South Fork of the Cosumnes River. On foothill parcels, fire exposure and well water are usually the first checks. See our El Dorado County guide.
What to check in any region
The questions that decide a vineyard’s value are the same everywhere, even though the answers come from different agencies.
- Water. Well yield and quality, surface water rights, frost-protection water, and whether the parcel sits over a groundwater basin with a sustainability plan. Our guide to vineyard water rights explains the legal side.
- County rules. Agricultural zoning, minimum parcel sizes, whether a home or a winery is allowed and what permits a tasting room needs. These differ sharply between counties in the same AVA.
- The vines. Age, rootstock, clone, spacing, virus status and remaining productive life.
- The income. Grape contracts, their term, price and buyer, and recent tonnage. In this market, a contract can matter more than the AVA.
- Fire, frost and smoke. Fire hazard zone, insurance availability, frost history and any smoke-taint claims.
- Contracts and land programs. Williamson Act contracts, conservation easements and leases that run with the land.
Our vineyard due diligence checklist turns that into a document list for escrow.
Pricing a vineyard outside Napa and Sonoma
Price per acre is a weak guide in these regions. A planted acre’s value depends on what its fruit earns, and district grape prices in 2025 ranged from Napa’s $6,635.85 a ton down to $333.73 in District 13 (Madera, Fresno and neighboring counties), so a vineyard’s income can differ many times over between regions. Many smaller vineyards also sell mainly for the house and the setting, which buyers value on a different basis from farming land.
Price each part separately: the home and improvements, the planted acres on their documented income, plantable land at its development cost and water, and unusable ground at its land value. Our guide to vineyard valuation walks through the approaches appraisers use.
Napa and Sonoma: where to read more
If you’re also considering the two best-known counties, our guide to the Napa Valley appellation covers all of its nested AVAs, and our guide to Sonoma’s wine appellations covers Sonoma County’s. Both explain the county rules that decide what a vineyard can become.
Questions people ask
Where are vineyards for sale in California outside Napa and Sonoma?
In Northern and Central California, the main vineyard regions are Mendocino, Lake County, Solano’s Suisun Valley, the Livermore Valley, the Santa Cruz Mountains, Monterey, the Delta around Clarksburg, Lodi and the Sierra Foothills, along with Paso Robles and Santa Barbara County farther south.
Which California wine region has the highest grape prices?
Napa County, by a wide margin. Its 2025 average was $6,635.85 a ton, followed by Sonoma and Marin at $2,762.88, according to the 2025 Final Grape Crush Report.
Is now a good time to buy a California vineyard?
We can’t predict prices, but the market currently favors buyers: the crush and grape prices fell in 2025, and tens of thousands of acres have been removed since 2024. That also means income is less certain, so documented grape contracts matter more than usual.
Does an AVA control what I can build on a vineyard?
No. An AVA is a wine-labeling boundary. Zoning, winery permits, grading and water rules come from the county and the state.
How much of a wine must come from an AVA to use its name?
At least 85% of the grapes must be grown inside the AVA. A county appellation requires at least 75% from that county.
Are small vineyards for sale in California a good way to start?
They can be, especially paired with a home, but most small vineyards don’t support themselves on grape sales alone. Budget for farming costs, check whether a grape buyer will take the fruit, and value the home and the vineyard separately.
Does Diamond handle vineyards in all of these regions?
Diamond’s service area includes Napa, Sonoma, Marin, Mendocino, Lake, Solano, Alameda, Contra Costa, Santa Clara, San Mateo, Santa Cruz, Monterey, Sacramento, Yolo, Placer, Nevada and El Dorado counties. For regions outside them, we can refer you to a broker there.
