The information in this, and other sections, complements the material in Australian Winemaking. Australian Winemaking provides a broad overview of the basis for winemaking processes and outlines the techniques necessary for making sound wine, while ‘Microbiological analysis of grapes and wine: techniques and concepts’ provides the information for conducting many of the microbiological analyses required throughout the winemaking process.

Patrick Iland OAM
Dr Patrick Iland (BAppSc, MAgSc, PhD) has been involved in wine education for over 35 years. He is a former Senior Lecturer at The University of Adelaide, Australia. Patrick has taught and researched in the areas of wine chemistry, viticulture and sensory evaluation. His research focused on the effects of viticultural practices on grape and wine quality and wine sensory properties. He, along with colleagues, developed the ‘berry colour ’ measure — a measure widely used in the viticulture industry for determining the colour of black grapes. Although retired, he retains his connection with the University as a Visiting Research Fellow. He is a past winner of the Stephen Hickinbotham Memorial Trust Award (for his research on Pinot Noir grapes and wines) and the Stephen Cole the Elder Award for Excellence in Teaching awarded by The University of Adelaide. In 2007 he was awarded the Order of Australia (OAM) for his services to the Australian wine industry. Patrick has a strong interest in and commitment to education. He and his wife Judith conduct a publishing business specialising in educational wine books.
