California growers rip out 47,229 acres of wine grapes in one year

California wine grape growers removed 47,229 acres of vineyards between August 2025 and August 2026, according to the 2026 Wine Grape Mapping Project released last week by the California Association of Wine Grape Growers.

The removals follow nearly 40,000 acres pulled out the previous year. Combined, the two years of cuts leave the state with just over 439,000 standing vineyard acres. That is the sharpest contraction in recent memory for a sector once anchored by reliable export demand and a loyal domestic consumer base.

Why are growers pulling vines?

Two forces are squeezing the market at once: trade disruption and a generational shift in drinking habits.

Canadian provinces pulled U.S. wine from government-run liquor store shelves in March 2025, retaliating against American tariffs. The Wine Institute reports U.S. wine exports to Canada have collapsed from nearly $40 million a month to just over $5 million — a decline of almost 90%. To put that in perspective, the sector is losing roughly $35 million in export revenue every month, or more than $400 million on an annualized basis, from the Canadian channel alone. That business is not expected to return soon.

Domestic demand is softening in parallel. Silicon Valley Bank's annual wine industry report notes that baby boomers have passed peak consumption, while adults under 30 "drink less than any similarly aged group as far back as records go," choosing seltzers, beer and spirits instead.

What does the crop picture show?

Roughly half of this year's California wine grape crop went into harvest without a buyer contract, according to Jeff Bitter, president of Allied Grape Growers. In a typical year, 70-80% of the crop is grown under contract.

Uncontracted fruit leaves growers exposed to spot prices at harvest, and the widening gap from historical norms signals how deeply buyers have stepped back from long-term commitments. For growers deciding whether to replant, retrain or remove, the contracting numbers carry as much weight as the acreage totals.

How low can acreage go?

The industry is split on where the floor sits. Some growers warn that dropping below 425,000 acres risks a future shortage once demand recovers. Others argue the market will not stabilize until acreage falls under 400,000 — roughly 40,000 acres below today's level.

If the second camp is right, tens of thousands more acres could still come out before wine sales find a bottom. Analysts expect that bottom to arrive in 2027 or 2028.

The 439,000-acre figure gives both sides a common reference point. Growers weighing removal decisions in the coming season will be watching whether Canadian export volumes recover, whether under-30 consumption patterns shift, and how much of the 2027 crop secures contracts before harvest.
