Systembolaget exists for one reason: To minimize alcohol-related problems by selling alcohol in a responsible way, without profit motive.
The first alcohol monopoly ever started in the mid 1800s in Sweden. It worked so well that the model was spread all over the country. In 1955, the local companies were merged to form a single, national Systembolaget company, a concept which still works.
Systembolaget has a nationwide retail network of 431 stores and approximately 500 agents serving smaller communities. The agents do not carry items in stock, but the entire product range can be ordered through them
