Prohibition Party
The Prohibition Party's proudest moment came in 1919, with the passage of the 18th Amendment to the United States Constitution, which outlawed the production, sale, transportation, import and export of alcohol. The era during which alcohol was illegal in the United States is known as "Prohibition".
Napa County wine
As the turn of the twentieth century approached, a series of setbacks commenced that devastated the Napa County wine industry for decades. A phylloxera outbreak decimated the wine grape crop, and this was followed by Prohibition in 1918, which made the production and transportation of alcohol illegal in the United States. In 1933, when Prohibition was repealed, the United States was in the midst of the Great Depression, and as a result the Napa County wine industry did not fully recover until 1960’s.
