Irish whiskey
Ireland once dominated the world's market for whiskey, producing 90% of the world's whiskey at the start of the 20th century. However, as a consequence of bootleggers during the prohibition in the United States (who sold poor-quality whiskey bearing Irish-sounding names thus eroding the pre-prohibition popularity for Irish brands) and tariffs on Irish whiskey across the British Empire during the Anglo-Irish Trade War of the 1930s, sales of Irish whiskey worldwide fell to a mere 2% by the mid-20th century. In 1953, an Irish government survey, found that 50% of whiskey drinkers in the United States had never heard of Irish whiskey.
