This is a list of breweries in Scotland. Beer has been produced in Scotland for approximately 5,000 years. The Celtic tradition of using bittering herbs remained in Scotland longer than the rest of Europe. Most breweries developed in the central Lowlands, which also contained the main centres of population. Edinburgh and Alloa in particular became noted centres for the export of beer around the world. By the end of the twentieth century, small breweries had sprung up all over Scotland.
