It is presumed that the reason why the method of brewing soju is developed in Andong is closely related with the entry into Korean Peninsula of Won dynasty of China. In the 13th century, Won dynasty entered Korean Peninsula to construct the outpost in Jeju and the logistics bases in Andong and Gaeseong to attack Japan. Soju was very essential item for the military of Won dynasty so that soju was produced in the logistics bases. The tradition is inherited, and Andong is famous for Soju.
