Alcoholic beverages in Oregon [SEP] Introduction
Portland hosts North America's largest beerfest, and Oregon has produced a number of national and international award winning beers. In 1844, the Oregon territories voted to prohibit alcoholic beverages. This was repealed in 1845, but prohibition was reinstated in 1915, four years before the national alcohol prohibition. When national prohibition was repealed in 1933, the Oregon Liquor Control Commission (OLCC) was created. Unlike states that allow liquor sales in grocery stores, liquor in Oregon is sold only in OLCC run liquor stores and establishments that have liquor licenses, and the OLCC has strict guidelines and training to ensure that all licensed venues understand how to safely sell and serve alcoholic beverages.
