California growers removed 47,229 vineyard acres in a year, underscoring severe stress in the state's wine market

California wine grape growers removed 47,229 acres of vineyards from August 2025 through August, a steep cut that shows how much pressure has built across the state’s wine market.

The decline was reported in the 2026 Wine Grape Mapping Project from the California Association of Wine Grape Growers. The group said the state now has just over 439,000 acres of standing vineyard land after nearly 40,000 acres were also removed in the prior 12-month period.

The reduction comes as growers face weaker sales at home and a sharp loss of business in Canada, one of the most important export markets for U.S. wine. In March 2025, Canadian provinces pulled U.S. wine from government-run liquor store shelves in response to American tariffs. The Wine Institute has said U.S. wine exports to Canada fell from nearly $40 million a month to a little more than $5 million, a drop of almost 90%. The industry does not expect that business to recover soon.

Demand in the domestic market has also softened. Silicon Valley Bank’s annual wine industry report said baby boomers have moved past their peak years of wine consumption. The report also said adults under 30 drink less than any similarly aged group in the modern record and are more likely to choose hard seltzers, beer and spirits.

That shift has left a large share of California’s crop without committed buyers. Jeff Bitter, president of Allied Grape Growers, said about half of this year’s California wine grape crop went into harvest without a purchase contract. In a more typical year, he said, 70% to 80% of the crop would be under contract before harvest.

The acreage pullout is a direct response to that imbalance. Vineyard owners who cannot secure contracts or profitable grape prices often remove vines to cut losses and to avoid producing fruit that may not have a market. The back-to-back reductions also suggest that many growers do not see a quick rebound in wine sales.

The industry is divided on how much more acreage may need to come out. Some growers argue that the state should not fall below 425,000 vineyard acres because a later recovery in demand could create a supply shortage. Others believe the market will not stabilize until total acreage drops below 400,000, which would mean tens of thousands of additional acres could still be removed.

Some in the industry expect wine sales to find a bottom in 2027 or 2028, but that timeline remains uncertain. For wineries and the broader beverage business, the current adjustment may have effects beyond farming. If enough vineyards are removed, grape availability, pricing and future production capacity could tighten later, especially if consumer demand improves or export markets reopen faster than expected.

For now, the market signal in California is still negative. Growers are cutting vines after two years of large removals, export sales to Canada remain deeply reduced, and a much larger share of the crop is reaching harvest without a buyer already in place.
