California growers ripped out 47,229 vineyard acres in one year

California wine grape growers pulled out 47,229 acres of vineyards between August 2025 and August 2026, the 2026 Wine Grape Mapping Project reported last week. That's the second consecutive year of massive removals. Nearly 40,000 acres came out the year before.

The survey, released by the California Association of Wine Grape Growers, puts the state's remaining vineyard base at just over 439,000 acres. Two years ago, that figure stood closer to 525,000. The pace of removals hasn't slowed.

What's driving the pull-outs?

Two forces are squeezing margins at once: collapsed export demand and a shrinking domestic customer base.

On the trade side, 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 fallen from nearly $40 million a month to just over $5 million — a drop of almost 90%. Nobody in the trade expects that business back soon.

Domestically, Silicon Valley Bank's annual wine industry report points to demographics. Baby boomers, long the industry's consumption backbone, have passed their peak drinking years. Adults under 30, the report finds, "drink less than any similarly aged group as far back as records go" — they're reaching for seltzers, beer and spirits instead.

What does this change for growers' contracts?

Plenty. Jeff Bitter, president of Allied Grape Growers, said about half of this year's California wine grape crop went into harvest without a buyer contract. In a typical year, 70-80% of the crop moves under contract. Grapes without a home translate directly into farm-gate revenue risk — and into the bulldozers working through the state's vineyard rows.

How low can acreage go?

The industry can't agree on the floor. Some growers warn that dropping below 425,000 standing acres risks a future supply shortage — removing too much capacity now could leave the state short when demand recovers. Others argue the market won't stabilize until acreage falls under 400,000.

Read that second number carefully. It implies tens of thousands of additional acres could still come out of the ground before wine sales find a bottom, which most in the trade don't expect before 2027 or 2028.

What happens next

Watch two indicators. The 2027 mapping project will show whether removals continued at the 40,000-acre pace or slowed as the state approaches the disputed 400,000-425,000 acre threshold. And Canadian shelf space — the $35 million in lost monthly export revenue — will tell growers whether the demand side has stopped shrinking. Until one of those moves, the pull-outs aren't done.
