Zulu women making beer at Gudu's kraal, on the Tugela River. Umqombothi is a traditional beer made in the Transkei, from maize (corn), maize malt, sorghum malt, yeast and water. The term kraal primarily refers to the type of dispersed homestead characteristic of the Nguni-speaking peoples of southern Africa. The Tugela River is the largest river in KwaZulu-Natal Province, South Africa. In 1846 George French Angas (English explorer and painter) went to South Africa, where he spent two years in Natal and the Cape, working on a series of drawings and watercolors which were published in 1849 as The Kafirs Illustrated.
