California’s wine market is heading into the 2026 harvest with signs of another small crop, an earlier-than-usual growing season and continued financial strain across the industry, according to the June California Report released Thursday by Ciatti Company, a major wine broker based in Novato.
The report said vineyard development across the state remains well ahead of a normal timetable, raising the prospect of an early harvest and forcing growers, wineries and bulk wine buyers to make decisions sooner than usual. That shift comes as many growers with uncontracted vineyards are weighing whether to stop farming those blocks for the rest of the season, a move that could reduce grape availability later this year for buyers hoping to wait before making purchases.
Ciatti said the market response has been cautious and uneven. Buyers of grapes and bulk wine are still operating in a weak sales environment, with excess inventory hanging over much of the business. At the same time, suppliers are being warned that holding out for better offers may carry more risk than in past years because demand has not recovered in a broad or stable way.
The report described weather conditions in April and May as mostly normal in temperature, but less steady in rainfall. Precipitation was above average in April and below average in May, before parts of California’s Coast received heavy rain late in the month. Those conditions have led to reports of shatter and mildew in some vineyards. Mildew is a particular concern this season because some vineyards have already been mothballed, limiting management and disease control.
That combination of weather pressure and reduced farming activity is adding to uncertainty about crop size. Ciatti said buyers looking for current-vintage wines should keep in mind that the 2025 harvest was limited and that the 2026 crop is also likely to come in light. If that happens, the state could face a market with too much older inventory but tighter supplies of certain fresh wines and desirable grape lots.
The report points to a contradiction now shaping California wine. On one side, inventories remain large enough that many wineries are still struggling to clear tanks and warehouses. On the other, some growers may choose not to carry uncommitted fruit through harvest because farming costs remain high and contract opportunities remain uncertain. That means supply may not be available where and when buyers expect it, especially for specific varieties or regions.
Ciatti urged grape growers to tell brokers what fruit they have available so supply can be matched with buyers earlier in the season. It also encouraged prospective buyers to register their needs now rather than wait until harvest approaches. The message reflects a market where timing matters more than usual: an early crop can compress negotiations, logistics and winery intake schedules into a shorter window.
The broader backdrop remains weak consumer demand for wine in the United States. Ciatti cited the recently published BMO Wine Market Report 2026, which said that in less than a decade the amount of wine entering the U.S. market from California has fallen by nearly 25%. The same report cited a WineBusiness Analytics survey conducted earlier this year showing that only 25% of U.S. wineries were not carrying excess inventory. In other words, 75% were holding more wine than they wanted.
Those figures help explain why many operators are under pressure even as another smaller harvest appears possible. Lower sales volumes have reduced cash coming into wineries and growers at a time when borrowing costs and operating expenses remain elevated. Ciatti said credit and cash flow problems are acute across California wine and are likely to continue until case-good sales show sustained improvement.
There are some limited signs of relief. The report said some bottled wine programs have posted better sales performance, and SipSource data showed pockets of improvement in U.S. wholesaler depletions. But Ciatti made clear that these gains have not yet added up to full market stabilization. Bulk inventory remains substantial, and suppliers who reject current bids may find fewer options later if demand does not strengthen.
That pressure is already reshaping vineyard decisions across California. Growers are continuing to remove acreage or place vineyards into temporary rest because returns no longer justify full farming costs on every acre. Ciatti said reductions in vineyard area and in the number of operators will continue unless bottled wine sales recover enough to restore confidence throughout the supply chain.
For growers, the decision is practical as much as strategic. Farming an uncontracted vineyard through summer requires spending on labor, irrigation, pest control and disease management without any guarantee that fruit will sell at a profitable price. In a normal year, some producers might take that risk in hopes of finding a buyer closer to harvest. This year, with development running ahead of schedule and demand still fragile, more may decide not to do so.
For wineries and négociants that rely on spot-market fruit or bulk purchases, that creates a different kind of risk. Even though overall inventories remain high, specific categories may tighten quickly if growers pull back from farming or if disease pressure reduces yields in vulnerable sites. Buyers who need grapes for existing brands or short-term production gaps may have less flexibility than headline inventory numbers suggest.
Ciatti’s June report did not present the early harvest as a sign of market recovery. Instead, it framed it as another stress point for an industry already dealing with falling consumption, oversupply in some segments and shrinking margins almost everywhere. The company’s advice to both sides of the market was direct: communicate earlier, assess options realistically and avoid assuming that time will improve bargaining power.
That tone reflects how sharply California’s wine economy has changed from its expansion years. A smaller crop once tended to support prices by tightening supply. Now it arrives in a market where many wineries already have too much unsold wine while many growers still cannot count on profitable contracts. The result is a fragmented landscape where shortages and surpluses can exist at the same time depending on variety, appellation, quality tier and packaging plan.
As summer begins, much will depend on weather through veraison and ripening, on whether mildew remains contained, and on how many growers decide it no longer makes sense to carry uncontracted fruit toward harvest. For now, brokers say one thing is clear: California’s 2026 vintage may arrive early, but the industry’s larger problems are not moving toward a quick resolution.
