Vineyards & Wineries for Sale in Napa County

Napa County vineyard land is scarce, tightly regulated and the most valuable in California: Napa grapes averaged $6,635.85 a ton in 2025, more than twice Sonoma’s average, and the county has protected its farmland since creating the nation’s first agricultural preserve in 1968.

That makes value highly specific to each property. AVA, planted versus plantable acres, vine health, water, permits and contracts can separate two similar-sized parcels by millions of dollars. This guide explains what drives Napa vineyard value, the county rules buyers and sellers need to know, and what the 2025 numbers mean for the market.

The market in numbers

• Grape prices: Napa County (crush district 4) averaged $6,635.85 a ton for all varieties in 2025, down 5%, on 144,807 tons (2025 Final Grape Crush Report; Fresh Fruit Portal).
• Crop value and acreage: the county’s 2025 crop report valued winegrapes at about $968.7 million, roughly 99% of all agricultural production, and producing vineyard fell to 42,937 acres from 45,967 (Napa Valley Register; Napa County).
• Land values: a study of Napa County Assessor appraisals from 2017 to 2021 found average appraised values of about $632,598 an acre for vineyard parcels of 1 to 10 acres, $190,645 for 10 to 40 acres and $145,683 for 40 to 100 acres. These are appraisals, not sale prices, but they show how much small parcels with homes skew per-acre figures (Wine Business Journal). An agricultural lender told Farm Progress in 2025 that prime Napa vineyards can sell for over $500,000 an acre (Farm Progress).

Lower prices and fewer producing acres point to a market where buyers have more leverage than they did a few years ago, especially on vineyards without strong contracts or a top AVA.

What drives Napa vineyard value

AVA and site

The Napa Valley AVA, recognized in 1981 as the first on the West Coast, contains a series of nested AVAs (Napa Valley Vintners). The newest, Crystal Springs of Napa Valley, covers about 4,000 acres and took effect in November 2024 (TTB). Wines from a nested AVA must also carry “Napa Valley” on the label. Within each AVA, elevation, slope, soil, drainage and exposure decide which varieties do best and what wineries will pay. Our town guides for Oakville, Rutherford, St. Helena and Calistoga cover the local setting, and our Napa Valley appellation guide explains the AVAs.

Planted vs plantable acres

Planted acres earn income now. Plantable acres are worth less until they’re permitted and planted, and in Napa that’s a real hurdle (see the rules below). Be wary of listings that count plantable land as if it were vineyard.

Vines and improvements

Vine age, rootstock, clone, spacing, trellis, irrigation and disease history all affect yield, quality and how soon a block needs replanting. Our vineyard due diligence checklist lists what to inspect.

Contracts, brand and income

Long-term grape contracts with established wineries, a recognized vineyard designation, or an existing winery and brand can add significant value. Buyers should verify every contract’s term, price, assignability and termination clauses. Our vineyard valuation guide explains how income, land and improvements are weighed.

Napa County rules buyers need to know

• Agricultural Preserve: created by Ordinance 274 on April 9, 1968, and described as the first in the United States (Napa County Grand Jury).
• Winery Definition Ordinance (1990): new or expanded wineries must source at least 75% of their grapes from Napa County, and new wineries need a parcel of at least 10 acres (Napa County Grand Jury).
• Conservation Regulations (County Code chapter 18.108): earth disturbance on slopes over 5% needs an agricultural erosion control plan; work on slopes of 30% to 50% or within stream and wetland setbacks needs a use permit exception; in the Agricultural Watershed district, owners must keep 70% of the tree canopy that existed on June 16, 2016, in mapped forest and oak woodland, with oak removal offset at least 2 to 1 (Napa County).
• Groundwater: the state approved the groundwater sustainability plan for the Napa Valley Subbasin in January 2023 (California Natural Resources Agency).
• Taxes: new vines are exempt from property tax until three years after planting (R&T Code 211), and Williamson Act contracts bind later buyers, with a cancellation fee of 12.5% of market value (Department of Conservation).

Together these rules make new vineyard development slow and expensive, which supports the value of existing, permitted vineyards. Our vineyard development guide covers planting and replanting.

For buyers

1. Decide what you’re buying: a home with vines, an income vineyard, a winery site or a brand. Each needs different due diligence and financing.
2. Verify the income: contracts, five years of yields and prices, and actual farming costs.
3. Check permits and water: erosion control plans, use permits, well logs and the groundwater plan.
4. Budget for replanting if the vines are older or diseased.
5. Plan the farming: most owners hire a manager. See our vineyard management guide.

More detail is in our guide to buying a vineyard.

For sellers

Buyers will price in anything they can’t verify. Organize contracts, block maps, yields, vine records, permits, water data and any winery approvals before you list. Decide whether to market broadly or approach a short list of likely buyers, and time the sale around the farming calendar so buyers can see the vines in leaf and the crop. Our guide to selling a vineyard or winery walks through it.

Napa vs Sonoma vineyards

Napa’s grape prices and land values are far higher, and its rules on new plantings and wineries are stricter. Sonoma County has more AVAs, more acres and a wider range of price points. Compare the two in our guide to vineyards and wineries for sale in Sonoma County, or start with the vineyards and wineries guide for both counties. For the county as a whole, see our Napa County guide, and when you’re ready, contact us.

Questions people ask

How much does an acre of Napa vineyard cost?

There’s no single figure. Appraisal data show small parcels averaging over $600,000 an acre, largely because of the homes on them, while larger vineyards average far less per acre. Prime sites can exceed $500,000 an acre on their own.

Can I build a winery on my Napa vineyard?

Only with a use permit, on a parcel of at least 10 acres, and with at least 75% Napa County fruit, among other conditions.

Can I plant more vines on a hillside?

Possibly, but slopes over 5% need an erosion control plan, steeper slopes need an exception, and canopy-retention rules apply in the Agricultural Watershed district.
