A I Perold (1880-1941) was South Africa's first Professor of Viticulture and Oenology. He dedicated himself to improving the quality of grapes for wine, brandy and the table. He studied wine and brandy production in Europe, imported more than 60 varieties to the Cape and bred new ones. Perold said this book "is intended to serve both the student and the practical grape-grower. There are in it technical passages that will appeal more to the student, e.g. the chapters dealing with the biology of the vine, its external and internal morphology, the theory of grafting. My remarks on the practice of viticulture, such as those dealing with the propagation, manuring and pruning of the vine, the production of table grapes for export, will, it is hoped, assist the practical grape-grower as well as the student."
