Yolo County Vineyards for Sale: Every AVA Explained

Five federal AVAs include Yolo County land: Clarksburg, Merritt Island, Dunnigan Hills, Capay Valley and Winters Highlands. Clarksburg crosses into Sacramento and Solano counties, while Winters Highlands crosses into Solano. Delta vineyard blocks and western hill properties have different drainage, access, water and land-use considerations.

For a purchase or sale, separate the vineyard’s production economics from the residence, other land, equipment and operating approvals. This guide connects the federal wine geography to the records that matter for Yolo County property; it does not represent current listing availability or a guarantee of development permission.

Every Yolo County AVA: federal boundaries and scope

Source: TTB’s current established-AVA directory and 27 CFR Part 9. County lists are an orientation aid. Use the regulation’s boundary description and approved maps to locate the planted block. Total AVA area is not planted acreage, a parcel-size rule or available property inventory.

Clarksburg and Merritt Island: the Delta

Clarksburg is river country. The soils mix silt, clay, sand and loam with low to moderate organic matter and poor drainage, so growers rely on ditches, canals and sometimes tile drains, and often choose rootstocks that tolerate wet ground.

Merritt Island is a separate appellation within Clarksburg and lies in Yolo County. A property can qualify for a nested appellation without being subject to the same county administration as another Clarksburg holding. Document drainage, levee obligations, irrigation and the planted block’s location independently.

Clarksburg property is usually flat, irrigated and large, often a vineyard block within a bigger farm that also grows row crops or orchards, with a farmhouse and shop near the levee road. The questions that decide value are drainage, levee and flood history, the water source and the grape contract. The area also sits in the Delta’s Primary Zone, which brings an extra layer of land use review (see the zoning section below).

Dunnigan Hills: warm hills with good air drainage

The main soils are well-drained gravelly loams on terraces and well-drained clays and silty clay loams over sandstone.

Buyers find large planted ranches, often with a mix of vineyard, grazing and grain land, and some sites suited to a production winery. Ask how the vineyard is irrigated, how deep the wells are and where the fruit has been sold.

Capay Valley: the long valley along Cache Creek

The Capay Valley runs along Cache Creek in the northwest corner of the county, in hill country that borders Lake, Colusa and Napa Counties. The federal rule describes hot, dry summers, a long growing season and some moderating air from the Delta and the Bay. Soils range from silty clay loams on alluvial fans to loams over sandstone on the slopes, with pockets of creek rock and volcanic ash.

Property here is usually a diversified farm or rural home with orchards, row crops or grazing and a few acres of vines. Fire exposure and road access matter more than in the Delta, and the water source can range from creek rights to a well.

Winters Highlands: the newest Yolo appellation

TTB’s rule describes gentle to steep slopes on alluvial fans and terraces, mostly fine clay or loamy soils that drain well or moderately well, wide day-to-night temperature swings and a long frost-free season.

Winters Highlands is shared with Solano County and is not nested in North Coast or another established AVA. For a mixed orchard and vineyard offering, separate the production records and water needs of each crop. The federal name does not establish current inventory, a price premium or permission for a winery.

What the 2025 crush report shows for Yolo grapes

The Final 2025 Grape Crush Report was released April 30, 2026. The following figures use Table 2 wine-grape tonnage and Table 6’s TOTAL WINE weighted average grower returns per ton on a delivered basis for purchased grapes. They are not AVA-specific prices or vineyard land values.

This county is split among crush districts. District 9 uses the report’s Interstate 80/U.S. 50 boundary for Yolo and U.S. 50 for Sacramento; Districts 11 and 17 further separate southern Sacramento at Interstate 5. Match the property to the report’s district definitions before selecting a comparison. Adding district tonnage would include fruit from other counties and would not produce a county total.

For valuation, begin with the vineyard’s actual fruit contracts: price formula, buyer, duration, assignability, quality specifications and rejection terms. Compare documented yield and collected receipts with farming and capital costs. A district average is context; it does not show a particular block’s saleable crop or net income. See vineyard valuation for the property analysis.

Zoning and farmland rules

Yolo’s official zoning page links the adopted agricultural regulations and confirms that its linked searchable code has the same text as the county’s PDFs. Use that current code for A-N and A-X parcel-creation rules, winery uses and special agricultural activities. Section 8-2.404 applies agricultural mitigation to conversion to predominantly non-agricultural use; it is not a fee automatically triggered by every vineyard planting. Its base ratios distinguish prime and non-prime farmland, with defined adjustments and exceptions. Do not reduce the priority-area adjustments to a simple city-sphere rule. Check the exact project footprint, land classification and current standards before valuing a winery or event expansion as feasible. See the responsible county’s current guidance and source record.

Local land-use permission, California ABC licensing and TTB wine-premises approval are separate requirements. A Type 02 winegrower license authorizes wine production and sales within its privileges; it does not approve a residence, tasting room, event program, water system or wastewater arrangement under local law.

For land under a Williamson Act or Farmland Security Zone contract, obtain the recorded contract, preserve rules and any nonrenewal notice. The restrictions bind later purchasers. Enrollment does not guarantee a particular tax saving, and a sale does not automatically terminate the contract. Conservation easements must be reviewed independently.

Water: the Yolo Subbasin, surface water and drainage

On Delta land near Clarksburg and Merritt Island, water delivery, drainage and levee dependence should be assessed together. In the Dunnigan Hills, Capay Valley and Winters area, identify the actual source and its seasonal performance rather than inferring it from the AVA. Use DWR’s basin map and current local agency rules for the parcel; Yolo’s county boundary, crush districts and groundwater basins do not coincide. Obtain diversion or service documents, pumping and quality records, storage information and any shared-system agreements. Review whether a proposed winery changes domestic, process-water or wastewater requirements.

Sources: official water-agency guidance, DWR basin prioritization and maps and the SGMA Portal for current plans, alternatives and agency records. Our vineyard water-rights guide explains the records to assemble. A groundwater-plan approval is not a transferable water right or a property-specific supply guarantee.

Fire, flood and other hazards

Use the State Fire Marshal’s current Fire Hazard Severity Zone maps for the actual parcel and confirm local adoption where applicable. State Responsibility Area maps took effect in April 2024; the state released its Local Responsibility Area recommendations in 2025. Hazard classification describes the mapped hazard, not a guarantee of property-specific loss or insurance terms.

Delta locations need flood and drainage analysis; western hill properties require particular attention to access and vegetation. Neither setting is free of other hazards. Obtain an insurance quote, inspect access and water storage, and review defensible-space and improvement conditions before removing contingencies. For a producing vineyard, obtain smoke-exposure, fruit-testing and buyer-rejection records separately from the property’s burn history.

Due diligence checklist for Yolo vineyard land

1. Map each planted block against the current CFR boundary and establish the actual county or city land-use jurisdiction.
2. Obtain current zoning, overlays, the legal parcel record and the approvals for the specific existing and proposed uses.
3. Read recorded agricultural contracts, conservation easements, access and utility agreements; identify obligations that continue after sale.
4. Separate planted, bearing, harvested and usable expansion acreage; obtain block maps, planting years, varieties, rootstocks and condition records.
5. Read fruit contracts, collected receipts, yield history, rejection terms and operating costs; distinguish land value from an operating business.
6. Verify the water source, rights or service agreement, current agency requirements, seasonal capacity, quality, storage and any drainage obligations.
7. Review building and wastewater approvals, physical access, parcel hazards and an insurance quote before relying on expansion potential.

Questions people ask

What AVAs are in Yolo County?

Five: Clarksburg, Merritt Island, Dunnigan Hills, Capay Valley and Winters Highlands. Clarksburg is shared with Sacramento and Solano Counties, Winters Highlands with Solano County, and Merritt Island lies inside Clarksburg.

What is the newest AVA in Yolo County?

Winters Highlands, which took effect on September 28, 2023. It covers about 7,296 acres in Yolo and Solano Counties near Winters and is not inside any other appellation.

Is Clarksburg in Yolo or Sacramento County?

Both, and Solano County as well. The appellation boundary crosses the counties; the actual parcel location determines local land-use jurisdiction and should be checked separately from the wine name.

What does the state report show for Clarksburg-area grape prices?

Clarksburg-area land is commonly compared with District 17, which also includes other land. Table 6 of the final 2025 report shows a district wine-grape weighted average grower return of $594.26 per ton for purchased grapes. It is not an exact Clarksburg AVA or vineyard contract price.

How much tonnage did District 17 report?

Table 2 of the final 2025 report records 159,816.5 tons of wine grapes in District 17. It combines southern Yolo with the Sacramento area south of U.S. 50 and west of Interstate 5; it is not Yolo-only.

What minimum parcel rules apply to a Yolo vineyard?

Apply the current agricultural zone’s parcel-creation standards to the proposed split, crop use and irrigation. Minimums for creating new parcels do not automatically establish the legal status or divisibility of an existing holding.

Does planting a vineyard automatically trigger farmland mitigation?

Section 8-2.404 concerns conversion to predominantly non-agricultural use, with defined base ratios, adjustments and exceptions. Evaluate the actual project; a winery, visitor use or other development is different from planting or replanting vines.

How does the Williamson Act affect a Yolo vineyard purchase?

Obtain the recorded contract, current county preserve rules and any nonrenewal notice. Restrictions bind later purchasers. A historic county-wide enrollment percentage does not establish the contract status or tax benefit for a particular parcel.

How should Yolo groundwater requirements be checked?

Use DWR’s basin map and the current local groundwater agency record for the parcel. Then verify the actual source, seasonal performance, rights or service terms, and any pumping or reporting requirements.

Where is Dunnigan Hills AVA?

It is in Yolo County, with its federal boundary in 27 CFR 9.145. Compare the actual terrain, irrigation source, soil and block configuration rather than assuming an appellation description establishes uniform farming conditions.

What hazards matter for Yolo vineyard property?

Delta parcels require flood, levee and drainage analysis; western hill properties need particular attention to fire exposure and access. Check the actual parcel and crop smoke history rather than treating either region as free of other risks.
