The Dutch East Indies colonial sugar industry originated in Tegal and the nearby city of Pekalongan, approximately to the east. Tegal Regency remained a major sugar production center until the mid-20th century. The city served as a port for exporting sugar produced on the nearby plantations. Tegal is famous for its warung, commonly called "warteg" or warung tegal. It is also known for its tea products, such as teh botol Sosro, Tong Tji tea, 2 Tang tea, Gopek tea and other brands.
