(Decanter) - The end of the state-controlled sale of spirits in Washington State took place at the end of May, and has many retailers worried about the impact on wine sales. When Prohibition ended in 1933 a handful of state governments elected to control alcoholic beverage sales, but consumers have been gradually trying to change the system. Washington State allows privately-owned wine shops but controls the sale of spirits. Now, after the Supreme Court voted to uphold I-1183, the ground-breaking legislation allowing private sales of spirits in stores of more than 10,000 square feet (930 square metres), the alcohol retail landscape will look very different.
