John Considine has had a lifetime of association with viticulture and for most of his professional life has been associated with viticulture. He has served on national R&D boards and on state authorities. His particular interest in wine grew from a large collaborative research project on the interface between viticulture and the composition and quality of Chardonnay for wine in the Margaret River Region of Western Australia. This text grew out of a course he developed for undergraduate and mature-age postgraduate students.Elizabeth Frankish is a food safety consultant with extensive experience in diagnostic microbiology and risk management for the food industry, including the horticulture, seafood, dairy, and meat sectors.
