California’s wine industry is experiencing one of its most significant market corrections in decades, as falling consumption, excess inventory, rising borrowing costs and trade tensions put increasing pressure on wineries across the state.
From premium estates in Napa Valley and Sonoma to large-scale producers in the Central Valley, businesses are seeking bankruptcy protection, selling assets or shutting down operations as the downturn deepens.
The financial strain has become increasingly visible. In August and September 2025, Napa Valley’s Signorello Estate and Sonoma’s Gundlach Bundschu filed for Chapter 11 bankruptcy protection. In late September, McManis Family, a major Central Valley producer, put its main winery and approximately 3,500 acres on the market.
These developments add to a growing list of restructurings, closures and distressed property sales, highlighting the scale of the adjustment facing America’s largest wine-producing state.
Falling Consumption Exposes Years of Oversupply
At the heart of the crisis is a widening gap between wine production and consumer demand. According to Impact Databank, U.S. wine sales fell below 300 million cases in 2025, down from a peak of 344 million cases in 2021.
The pandemic temporarily boosted wine sales, encouraging many producers to expand inventories, vineyard plantings, hospitality facilities and production capacity. However, the increase in demand proved temporary, while the industry's investments continued to shape its cost structure.
Rob McMillan, a wine industry analyst at First Citizens Bank, has repeatedly warned about slowing consumption and the risk of oversupply. In his assessment, the pandemic-era sales increase obscured longer-term changes in demand, leading some businesses to continue expanding when a more cautious approach was warranted.
Several factors are now contributing to weaker sales. Younger consumers have different drinking habits from previous generations, health concerns are influencing alcohol consumption, and competition from other beverages has intensified. At the same time, higher living and travel costs have made consumers more selective about discretionary purchases, including premium wine and winery visits.
Jeff Bundschu, chief executive of Gundlach Bundschu, has argued that many producers built their businesses around demand levels, pricing and consumer behavior that no longer reflect current market conditions.
The result is an industry carrying excess capacity at a time when selling wine has become more difficult.
From Unsold Grapes to Financial Distress
The downturn initially hit grape growers, particularly in California’s value-oriented wine regions.
By 2023, wineries were reducing production and canceling established grape-purchasing contracts, with particularly strong effects in Lodi and the Central Valley. As wineries bought fewer grapes, growers faced falling demand and pressure on grape prices.
By 2024, the correction had spread into premium coastal regions, where vineyard removals began to accelerate.
Jeff Bitter, president of Allied Grape Growers, estimated that approximately 25% of California’s wine grape vines had been uprooted by the time of his assessment. Land IQ, a vineyard consulting firm, reported that approximately 38,000 acres were removed between October 2024 and August 2025 alone.
These removals reflect an effort to bring production capacity closer to actual market demand. However, reducing vineyard acreage does not immediately eliminate the surplus already held in tanks, barrels and bottled inventory.
Bulk wine brokers Turrentine and Ciatti reportedly continued to hold unsold 2022 and 2023 vintages, illustrating how the effects of earlier production decisions are continuing to weigh on the market.
Excess supply puts downward pressure on prices, makes inventory harder to sell and reduces the cash available to service debt. For wineries with significant fixed costs, this combination can quickly become a balance-sheet problem.
Rising Borrowing Costs Intensify the Pressure
Financial conditions have made the industry’s adjustment more difficult. Many wineries expanded through borrowing, financing vineyard acquisitions, hospitality projects, production facilities and inventory with debt.
As loans mature, businesses must refinance in a less favorable lending environment. Lenders have tightened credit to the wine sector, while distressed borrowers may face higher interest rates and more restrictive terms.
Peter Ekman, chief executive of Spring Mountain Vineyard and a restructuring specialist, has warned that these conditions could lead to additional bankruptcy filings and asset sales through at least 2028.
The pressure is particularly acute for wineries that have substantial inventories but insufficient sales to generate the cash flow needed to meet their obligations.
Owners approaching retirement are also reconsidering whether to invest additional capital in businesses facing an uncertain recovery. Some have opted to close rather than assume further debt or continue operating at a loss.
Recent developments across California illustrate the range of outcomes, from formal bankruptcy proceedings to the closure of long-established wineries and the sale of production assets.
Established Wineries Seek Restructuring or Exit
Several prominent businesses have been affected by the downturn.
Signorello Estate’s difficulties date partly to the 2017 Atlas Fire, which destroyed its winery on Napa Valley’s Silverado Trail. Owner Ray Signorello rebuilt the property, including a new cave winery, and reopened in 2024. However, the reopening coincided with a deteriorating wine market.
An August 27, 2025, bankruptcy filing listed debts between $10 million and $50 million. Court proceedings indicated that the winery and related assets could face auction unless the owners and major creditors reached an agreement.
Gundlach Bundschu, a family winery operating on the same Sonoma property since 1858, faced a different set of challenges. The company acquired the 60-acre Valley of the Moon property in late 2020 and introduced the Abbot’s Passage brand to appeal to younger consumers.
The expansion was financed partly through debt, but the anticipated growth did not materialize. Over the subsequent 18 months, the winery cut operating costs, ended vineyard contracts and reduced its workforce by approximately 50%.
Chief executive Jeff Bundschu said the company identified three potential investors or buyers, but lenders rejected the proposals. Gundlach Bundschu filed for Chapter 11 protection on September 23, 2025, seeking to continue operations during restructuring and preserve jobs.
The filing listed debts between $10 million and $50 million, with published estimates placing the total closer to $37 million. The family expects to remain involved in the business, potentially with a minority ownership stake following restructuring.
Other businesses have also been affected. Adelaida Cellars in Paso Robles filed for Chapter 11 and continued restructuring, while Robledo Family Winery in Sonoma Valley sought bankruptcy protection. Judd’s Hill in Napa Valley announced plans to cease winery operations after nearly five decades.
Calistoga Vintner Services, a custom-crush operation serving wine producers, was also scheduled for a foreclosure auction on October 16, 2025.
The cases demonstrate that the downturn is not confined to a single business model or price segment. Both established premium estates and larger production-oriented wineries are facing difficult decisions about debt, ownership and future operations.
McManis Family Puts Major Assets on the Market
McManis Family illustrates how the crisis is affecting larger producers that depend on high-volume sales and export markets.
Before the recent trade tensions and Canadian restrictions, approximately 40% of the company’s exports went to Canada. That business has since fallen to a fraction of its former level, according to the supplied industry account.
The loss of export demand has coincided with weaker U.S. demand for lower-priced California wine, putting additional pressure on a business model built around volume.
In late September 2025, the company offered its main production facility, including 122 acres, for approximately $22.5 million. Ten vineyards and the McManis brand were being marketed separately.
The proposed sales reflect an attempt to respond to a market in which both domestic demand and export opportunities have weakened. They also highlight the vulnerability of producers that depend on a combination of affordable pricing, large production volumes and access to major retail markets.
Trade Tensions Add to the Industry’s Difficulties
Domestic oversupply is not the only challenge facing California wine producers. Trade tensions have added costs and restricted access to important markets.
Tariffs have increased expenses for imported production inputs, including fertilizer and oak barrels. At the same time, most Canadian provinces stopped carrying U.S. wines amid the Canada-U.S. trade dispute.
According to the Wine Institute, U.S. wine exports to Canada fell 78% in 2025, reducing export value by $357 million.
For California producers already dealing with excess inventory, the loss of a major export destination has compounded the difficulty of finding buyers for existing stocks.
The Canadian restrictions have been particularly consequential for businesses that built substantial portions of their export strategies around the market. McManis Family’s experience demonstrates how a sudden change in trade conditions can expose the risks of relying heavily on a limited number of destinations.
Together, tariffs, weaker domestic consumption and reduced export access have narrowed the commercial options available to many wineries.
Vineyard Removals Could Eventually Tighten Supply
Despite the current difficulties, some industry observers believe the contraction could eventually rebalance the market.
McMillan has argued that the rise in bankruptcies and foreclosures represents part of a necessary correction, allowing weaker balance sheets and excess capacity to be removed from the industry.
Ekman is also anticipating a possible shift in supply conditions. After the 2020 Glass Fire damaged Spring Mountain Vineyard, he and his partners invested nearly $200 million in the property, and the estate is nearing completion of a major replanting program.
Ekman believes the scale of vineyard removals across California could eventually move the state from surplus toward a shortage of grapes in 2027 and 2028, particularly if demand stabilizes before replacement vineyards return to production.
That outcome remains uncertain. Vineyard removal can reduce future supply, but the speed of any recovery will depend on consumer demand, inventory levels, new planting decisions and the pace at which wineries rebuild financial stability.
The current surplus also means that reductions in grape production may take time to translate into higher prices for wine already in storage.
Consumers May Find Premium California Wines at Lower Prices
For consumers, the downturn could create opportunities to purchase wines from established California appellations at prices that were difficult to imagine during the industry's expansion years.
As producers work through excess grapes, bulk wine and bottled inventory, discounts may become more common in regions such as Sonoma Coast, Russian River Valley and Oakville.
However, lower prices will not necessarily be universal. The impact will depend on individual wineries' financial positions, distribution arrangements, inventory levels and willingness to reduce prices.
For importers, distributors and retailers, the changing market may create opportunities to source California wines more competitively. At the same time, buyers will need to assess the financial stability of suppliers and the continuity of production, especially when dealing with businesses undergoing restructuring or asset sales.
A Structural Reset for California Wine
California’s wine industry is facing more than a temporary sales slowdown. The combination of changing consumer habits, years of excess production, expensive financing and trade disruption is forcing businesses to reassess their scale, investments and market strategies.
Bankruptcies, winery closures and vineyard removals are painful consequences of that adjustment, affecting owners, employees, growers and local communities. Yet they may also help bring production capacity into closer alignment with demand over time.
The central uncertainty is how long the process will take. Even if vineyard removals eventually reduce the surplus, wineries must first work through existing inventories and navigate a more competitive market with less favorable financing conditions.
For now, California’s wine sector remains under pressure. The coming years will determine whether the current wave of restructuring produces a more sustainable balance between supply and demand—or whether weak consumption and financial strain continue to drive further consolidation across the state.
