California wine grape glut pressures growers

Many California wine grape growers are harvesting this season without buyers lined up for significant portions of their crop, reflecting a broad decline in demand for wine. Industry estimates indicate that roughly half of the state’s wine grape crop entered the harvest season without contracts, a sharp contrast with a typical year when about 70–80% of grapes are usually sold under contract before picking begins.

The unusual volume of uncontracted fruit underscores a mismatch between grape supply and current market needs. With fewer secure outlets at harvest, growers face tougher decisions on whether to harvest at uncertain prices, sell at a loss, or leave grapes unpicked.

Third-generation grower Bill Berryhill illustrates the pressure on producers. He reported having no buyers for grapes grown on 200 of his 500 acres, meaning that nearly half of his vineyard land currently lacks a market. In response, he plans to remove 50 acres of vines once the harvest season is over.

Berryhill’s situation reflects a broader pattern of vineyard adjustments as growers reassess how much land they can devote to wine grapes in a weaker demand environment. For some, pulling vines has become a necessary step to cut exposure to unprofitable acreage.

With oversupply and softer wine sales weighing on returns, some growers are selling vineyard land or replanting with other crops. Higher-demand alternatives such as almonds, walnuts, pistachios and olives are being considered or adopted in place of wine grapes.

This transition signals a gradual rebalancing of agricultural use in affected regions. By switching to crops with stronger or more stable demand, growers aim to improve the economics of their operations after several challenging seasons for wine grapes.

For grapes that remain unsold at harvest, options are constrained and often financially unfavorable. Some uncontracted fruit is sold at a loss to buyers that produce concentrated grape syrup, providing at least some revenue but below the returns of traditional wine sales.

In other cases, growers are leaving grapes on the vine or discarding them outright when no viable buyer can be found. These outcomes highlight the financial strain created when production costs are incurred but market demand fails to absorb the crop.

Industry sources point to weaker overall demand for wine as a key driver of the current oversupply of grapes. Reduced exports have added to the pressure, including the impact of tariffs that have curtailed shipments of U.S. wine to Canada.

These trade and demand headwinds are contributing to a challenging environment for California’s wine grape sector. Until supply better aligns with consumption and export trends, growers are likely to continue facing difficult choices about harvesting, pricing and land use.
