For thirteen years a constitutional ban dismantled American winemaking. What kept the craft alive was a sacramental exemption, a handful of stubborn wineries — and a block of dried grapes.

December 5 — known to American wine lovers as Repeal Day — deserves a toast. On that date in 1933, the Twenty-first Amendment was ratified, ending the Eighteenth Amendment, which for nearly fourteen years had banned the manufacture, sale, and transportation of alcoholic beverages.[1] Notably, the ban never outlawed simply owning or drinking alcohol — only making, moving, and selling it.[2]
No corner of American drink was reshaped more violently than wine. Beer and spirits found a shadow economy in speakeasies and bootlegging; wine, a slower craft tied to vineyards and aging, very nearly lost its culture altogether.
Prohibition didn’t just close wineries — it severed the knowledge, vines, and habits that a wine culture is built on.
How Prohibition Took Hold
Congress proposed the Eighteenth Amendment in December 1917, and it was the states that ratified it — the thirty-sixth and decisive state approving on January 16, 1919. National Prohibition took effect one year later, on January 17, 1920.[2]
The amendment set the principle; a second law supplied the teeth. The National Prohibition Act of 1919 — universally known as the Volstead Act — was the enforcement statute. It defined an “intoxicating” beverage as anything above 0.5% alcohol by volume and laid out the penalties for breaking the law.[3]
The law carved out alcohol for industrial and research use, for physician-prescribed medicinal purposes, and for sacramental wine used in religious worship. Those exemptions became lifelines for a small number of wineries.[4]
The Wineries That Survived
The old claim that almost no American winery predates 1933 is a myth. A licensed minority stayed open throughout Prohibition by producing sacramental and medicinal wine. In California, Beaulieu Vineyard, Beringer, Buena Vista, and Concannon all continued; in New York’s Hudson Valley, Brotherhood Winery — founded in 1839 and billed as America’s oldest continuously operating winery — never stopped.[5] Many others, however, tore out their best wine grapes and replanted to crops they could legally sell.
The Grape-Brick Loophole
The strangest twist is that Prohibition briefly made grape farming boom. The Volstead Act allowed a household to produce up to 200 gallons a year of “non-intoxicating cider and fruit juices” for personal use — a clause widely read as permission to make wine at home.[6] Demand for fresh grapes surged, and California growers shipped them east by the rail-car. Producers even sold compressed blocks of dried grape concentrate — “wine bricks” or grape bricks — packaged with a winking “warning” not to dissolve the brick in water and let it ferment, lest it turn into wine.[6]
The loophole kept grapes in the ground, but it favored tough, sweet shipping varieties over fine wine grapes — quietly eroding vineyard quality for a generation.
Why Spirits Ruled the Speakeasy
Prohibition reshaped what Americans drank, not just whether they drank. Bootleggers favored spirits for an almost mathematical reason: a bottle of 40%-alcohol whiskey carries far more “product” than the same bottle of 12% wine or 5% beer — more potency in less space, cheaper to hide and haul. It’s a pattern sometimes called the “iron law of prohibition”: ban a drink, and the trade shifts to its most concentrated form.[8]
Beer
~5%
Wine
~12%
Spirits
~40%
A given bottle of spirits carries roughly eight times the alcohol of the same bottle of beer — far more efficient to smuggle. Typical figures; source: U.S. National Institute on Alcohol Abuse and Alcoholism, “What Is a Standard Drink?”
That logic had a long tail. When repeal came in 1933, beer and spirits — quick to brew and distill — were back on shelves within months, while wine, bound to vineyards, fermentation, and aging, recovered slowly. Many growers had replanted to hardy, high-yield shipping grapes, and the country settled into decades of inexpensive “jug wine” before fine American wine re-emerged.[9]
Repeal, and a Long Road Back
On December 5, 1933, Utah became the thirty-sixth state to ratify the Twenty-first Amendment, repealing Prohibition outright.[1] But recovery was slow. Vineyards had been replanted to inferior grapes, expertise had scattered, and serious American fine wine would not regain international standing until the 1960s and ’70s — a comeback symbolically sealed at the 1976 Judgment of Paris.[7] Prohibition is just one chapter in the long history of wine, and its shadow even shaped the slow rise of Oregon’s own wine industry — the story we love bringing to life on our Willamette Valley wine tours.
Frequently asked questions

When did Prohibition end?
On December 5, 1933 – known to wine lovers as Repeal Day – when the Twenty-first Amendment was ratified, overturning the Eighteenth Amendment after nearly fourteen years of national Prohibition.
