On January 16, 1919 the Constitution of the United States of America was amended for the eighteenth time, this time turning the country upside down and in a frenzy by banning the sale of intoxicating liquors. Years of the Temperance Movement, pressure from the Anti-Saloon League and political pressure finally had caught up to distilleries. Although it did not ban the consumption of alcohol itself, it did regulate who could produce it and sell it during these years. The passing of the amendment shuttered distilleries overnight, many closing their doors for good and many brands lost to Prohibition. Even though it would eventually be overturned on December 5, 1933, over a decade of no sales for some producers were too much of a financial burden on them that they were forever lost to history. However, there were some licenses granted by the government to six distilleries that allowed them to continue to produce during these years to help supply the medicinal market. The below distilleries were allowed to produce during Prohibition and ultimately helped many of the brands in their portfolio survive the hardest years for distilleries to be able to be around today.
