What the 2025 Grape Crush Report Can Tell a Vineyard Buyer—and What It Cannot
By Matthew Martinez, Founder, CEO & Managing Broker, Diamond Real Estate Group. California DRE #01869679.
The 2025 California Grape Crush Report gives vineyard buyers useful evidence about the market for grapes. It does not give them a price list for vineyards. Moving from one to the other requires several additional steps, and skipping those steps can make a Wine Country acquisition look more financially certain than it is.
The report is most useful when its unit, geography, crop year and scope stay attached to the number. That discipline turns a headline into a sensible question about the actual vineyard being considered.
Read the published number on its own terms
The final 2025 report from CDFA and USDA NASS, published April 30, 2026, reports weighted average grower returns per ton on a delivered basis for purchased grapes. Its District 4 is Napa County. District 3 combines Sonoma and Marin counties.
The reported district averages are $6,635.85 per ton for Napa and $2,762.88 for Sonoma–Marin. These are historical grape-price observations within the report’s scope. They are not dollars per acre, vineyard sale prices, profit margins or quotations for the next harvest.
Why the district average is not your vineyard’s contract
A district average combines transactions with different varieties and commercial circumstances. A buyer needs to understand the property’s actual crop and agreements. Which blocks are producing? What varieties are planted? What quantity was accepted, under what agreement and in which season?
A historical district figure can help frame those questions. It should not silently replace a current contract price or establish that a buyer exists for future fruit. A vineyard can share a district with well-known producers without receiving the same terms.
The missing bridge is revenue per producing acre
Even a well-supported dollars-per-ton assumption needs a separate quantity assumption. Consider this arithmetic example, which is illustrative and is not a forecast for Napa or Sonoma: 4 tons per producing acre at $3,000 per ton produces $12,000 of gross grape revenue per producing acre. At 2 tons, the same price produces $6,000.
Neither result is net income. Neither states the value of the land. The example shows why copying a fruit-price average into a purchase model cannot answer the yield, expense or valuation questions.
| Measure | What it describes | What it leaves unresolved |
|---|---|---|
| Dollars per ton | A price for a quantity of grapes | Yield, expenses and land value |
| Tons per producing acre | Crop quantity relative to producing area | Price, saleability and cost |
| Gross crop receipts | Revenue before the relevant expenses | Operating profit and capital needs |
| Vineyard sale price | Consideration for a particular asset package | How its components compare with another property |
Expenses need a property-specific explanation
Labor, management, irrigation, materials, equipment, insurance and capital work affect the economics. Replanting and a major system replacement should not disappear because the current season’s routine operating expense looks manageable.
UC Davis cost and return studies provide regional production-budget context. The program distinguishes current studies from archived work. Use the relevant study’s assumptions as a comparison point, then reconcile them with the property’s records and current professional estimates. A regional study is not evidence of what the seller actually spent.
A residence and a working vineyard can support different value arguments
An estate with a desirable home and a small planted area may be bought partly for residential utility. A larger agricultural acquisition may depend more heavily on the operating plan. Neither should be priced by multiplying one crop statistic across the gross parcel.
Separate the residence, planted and producing blocks, other usable land, water infrastructure and additional improvements. Then explain how the relevant sales and income evidence support the combined conclusion. Our vineyard valuation guide develops those broader approaches.
The strongest use of the report is as a question generator
When an asking price is supported with a district grape average, ask to see the next step: the vineyard’s documented production, actual sales arrangements, operating expenses and capital requirements. If those inputs are unavailable, the financial conclusion remains provisional.
