Vineyards & Wineries for Sale in Sonoma County
By Matthew Martinez, Founder, CEO & Managing Broker, Diamond Real Estate Group. California DRE #01869679.
Sonoma County has about 60,000 acres of wine grapes across 19 American Viticultural Areas, and vineyard property here ranges from homes with a few rows of vines to working ranches and bonded wineries. Grape prices fell in 2025 and growers pulled thousands of acres, which has given buyers more room to negotiate.
The fundamentals haven’t changed: the AVA, water, vine health, contracts and county permits decide what a vineyard is worth. This guide covers the types of vineyard property for sale in Sonoma County, the current market, the rules that apply here and how to think about a vineyard as an investment.
Types of vineyard property in Sonoma County
| Type | What you get | What drives value |
|---|---|---|
| Home next to vineyards | Views without farming | The home, location, and what could change next door |
| Home with a hobby vineyard | A few acres of vines for home wine or a small grape sale | The home first; vines are a lifestyle feature |
| Small commercial vineyard with a residence | Grapes sold under contract, often with a manager | AVA, vine health, contracts, water, the house |
| Vineyard ranch or estate winery | Larger plantings, outbuildings, sometimes a bonded winery | Production, permits, brand, buildings |
| Plantable land | Bare or replant-ready acreage | Soil, slope, water, permits, time to first crop |
Our guide to buying a small hobby vineyard covers the first two in detail.
The market as of 2026
- Grape prices: Sonoma and Marin grapes (crush district 3) averaged $2,762.88 a ton in 2025, down 6% from 2024, on 186,846 tons crushed (2025 Final Grape Crush Report; Fresh Fruit Portal).
- Uncontracted fruit: Turrentine Brokerage reported Sonoma Chardonnay averaging about $2,370 a ton across the district while spot-market prices were closer to $800 (Wine Industry Advisor). A contract matters.
- Crop value: the county’s 2024 winegrape crop was worth $626.6 million, down 12.6%, on 211,512 tons (Sonoma County).
- Vineyard removals: a study for the state winegrape growers’ association counted about 2,700 bearing acres pulled in Sonoma County between October 2024 and August 2025 (Sonoma Index-Tribune).
For buyers, that means more negotiating room and more scrutiny of income. For sellers, documented contracts, yields and vine health matter more than ever. For the Napa side of the comparison, see vineyards and wineries for sale in Napa County.
Where the vineyards are
Sonoma County Winegrowers lists vineyard acreage by AVA, including Alexander Valley (about 15,000 acres), the Russian River Valley (13,896), Dry Creek Valley (8,055), Carneros (6,481), Sonoma Valley (5,565), Moon Mountain District (1,500) and Sonoma Mountain (667) (Sonoma County Winegrowers). The newest, the West Sonoma Coast AVA, was established in 2022 (Federal Register).
The AVA matters if you’ll sell grapes or wine: to put an AVA name on a label, at least 85% of the wine must come from grapes grown in that AVA (TTB). Since 2014, wines labeled with an AVA wholly inside Sonoma County must also show “Sonoma County” on the label (AB 1798). For town-level guides, see Healdsburg, Glen Ellen and Kenwood.
Rules that apply in Sonoma County
Planting and replanting
New plantings and replants need approval under the county’s vineyard and orchard site development ordinance (VESCO, County Code chapter 36) before work begins. Applications filed after September 15 may not be issued that year, and a lighter Low Impact Replant Registration exists for replants without deep ripping (Sonoma County). Our vineyard development guide explains the steps.
Water
The state approved groundwater sustainability plans for the Santa Rosa Plain, Petaluma Valley and Sonoma Valley basins in January 2023 (California Natural Resources Agency). Along the Russian River, frost-protection water diversions are regulated under 23 CCR 862, adopted in 2011 and upheld in court in 2014 (Downey Brand). Ask for well logs, pump tests and any water-right filings.
Taxes and land contracts
- Grapevines are exempt from property tax until three years after the season they’re planted (R&T Code 211).
- Williamson Act contracts bind later buyers and tax land on its farm use; canceling one costs a fee of 12.5% of current market value (Department of Conservation). Vacation rentals aren’t allowed on contracted land in the unincorporated county (Permit Sonoma).
Wineries and foreign buyers
Making wine for sale requires federal and state licenses; a California winegrower license (Type 02) requires winemaking facilities, though federal rules allow alternating proprietorships at another winery (California ABC). Foreign persons who acquire an interest in U.S. farmland must file a USDA report within 90 days (USDA FSA).
Is a Sonoma vineyard a good investment?
Treat the real estate and the farm as two separate things. The house and land may hold value even when grape prices are weak, and the vines may perform while the house needs work. Yield isn’t profit: grape revenue has to cover labor, management, water, equipment, insurance, taxes and a reserve for replanting. Many owners accept a modest or negative farm return because the vineyard supports a home, a brand or a family project. That’s a sound choice when it’s modeled honestly, not sold as passive income.
Before you buy, verify the seller’s figures: actual grape contracts and prices, five years of yields, farming costs and capital needs. Our vineyard due diligence checklist and vineyard valuation guide show what to ask for, and the vineyard management guide explains how farming arrangements work.
Selling a Sonoma vineyard
Buyers will ask for contracts, yields, block maps, vine age and rootstock, water records and permits. Having them ready shortens escrow and supports the price. Our guide to selling a vineyard or winery covers preparation, and the vineyards and wineries guide covers both counties.

Questions people ask
How much does a vineyard cost in Sonoma County?
It varies too much for a single figure: AVA, planted acres, vine age, water, buildings and the house all matter. We price each property from recent comparable sales and its income.
Can I live on a vineyard property and rent it out?
Possibly, but not on Williamson Act land in the unincorporated county, and not in some zones. Check the parcel’s zoning and contracts first.
Do I need a vineyard manager?
Beyond an acre or two, most owners hire one for at least the equipment-heavy work.
