The Royal Society of South Africa and the Academy of Science of South Africa invite you to a public lecture by Dr John P. Moore (MRSSAf), Senior Researcher in Grapevine Biochemistry and Biotechnology, Institute for Wine Biotechnology, Department of Viticulture and Oenology, Stellenbosch University on ‘The Art and Science of Winemaking’.

‘Wine for joy. Wine for sorrow. Wine to remember. Wine to forget.’ – although extreme fermented beverages date to the Neolithic or knowledge of ancient winemaking is heavily influenced by Egyptian tomb art. The Egyptian New Kingdom portrays some of the most interesting depictions of grape growing and winemaking in the Near East. Grapevine domestication is believed to have occurred much earlier in the first city states of the Fertile Crescent of Mesopotamia and the northern mountain ranges. The ancient Mesopotamians and Egyptians faced the same challenges we face today in modern winemaking; effective irrigation, ripening, harvest maturity, cultivar selection, disease management, wine processing and temperature control, preservation, storage, ageing and consumption. This talk will meander from art to science (and back again!) through the limited knowledge we can glean from the ancient past; and fast forward to the modern scientific-industrial process that global winemaking and distribution is at present. The advance of scientific understanding and its applications in the winemaking process will be highlighted with reference to particular examples from research conducted at the Institute for Wine Biotechnology at Stellenbosch University. Most recently the first scientifically supported model for how enzymes unlock the nutritious, antioxidant-rich polyphenols and aroma compounds in grapes during crushing and fermentation to red wine will be discussed. 

Date:     Wednesday 22 November 2017
