For thirteen years, it was illegal to make or sell wine in the United States. Prohibition should have been the death of American wine — and it very nearly was. Yet through a handful of ingenious loopholes, from altar wine to “grape bricks,” the vine survived the dry years, even as the industry around it collapsed1.
Quick facts
- Prohibition banned wine in the U.S. from 1920 to 1933.
- Of more than 2,500 wineries, fewer than 100 survived.
- Sacramental and medicinal wine stayed legal — a lifeline for some.
- Home winemakers and “grape bricks” kept the vineyards alive.
The dry years begin
When national Prohibition took effect in January 1920 under the Eighteenth Amendment and the Volstead Act, America’s young wine industry was gutted almost overnight. Before Prohibition there were well over two thousand commercial wineries; by the time it ended, fewer than a hundred were still standing1. Cellars fell silent, and there would be no compensation for the ruin.

The sacred loophole
The law left doors ajar. Wine for religious sacraments remained legal, and a fortunate few wineries stayed alive by making altar wine for churches — California’s Beaulieu Vineyard styled itself “The House of Altar Wines,” shipping its barrels marked “FLOUR.” Demand for sacramental wine soared — California grape production for it reportedly rose seven-fold2. Wine could also be prescribed as medicine and sold, quite legally, through pharmacies.
The wine brick



The strangest loophole of all concerned the home. The Volstead Act let each household make up to 200 gallons a year of “non-intoxicating” fruit juice — widely read as a licence to make wine at home. Demand for grapes exploded, prices soared, and California’s vineyards nearly doubled in acreage during the 1920s3. Enterprising firms sold blocks of concentrated grape juice — “wine bricks” and the famous Vine-Glo — complete with a tongue-in-cheek “warning” that was really a recipe: do not dissolve this in water, add yeast and leave it 21 days in a dark place, or it will ferment into wine4.
The grape that Prohibition made
This home-winemaking boom reshaped the vineyards for the worse. To survive the long rail journey to home winemakers in Chicago and New York, grapes had to be thick-skinned, so growers tore out fine, thin-skinned varieties like Cabernet in favour of tough, deeply coloured shippers — above all Alicante Bouschet5. The result was a paradox: more grapes than ever, but wine of ever-poorer quality, and a catastrophic loss of the knowledge and vines that make fine wine.
Repeal, and the long hangover
Repeal came at last on 5 December 1933, but it was no happy ending. The Great Depression was at its worst, the finest vineyards had been grubbed up, and skilled winemakers had scattered6. American wine emerged from Prohibition alive but crippled, and it would take decades — not until the 1960s and ’70s — before the country’s wine truly recovered. The vine had survived the dry years; the art of fine wine had to be rebuilt almost from scratch.
