Managing Wine Quality, Second Edition, Volume II: Oenology and Wine Quality brings together authoritative contributions from experts across the world's winemaking regions who cover yeasts, fermentation, enzymes, and stabilization, amongst other topics. A new chapter covers, in detail, extraction technologies and wine quality. Other sections cover the management of wine sensory quality, with new chapters covering the management of fortified wines, of Botrytized wines, and of wines produced from dried grapes. In addition, an updated section on insect taints in wine has been widened to cover all insects.
With a focus on recent studies, advanced methods, and a look to future technologies, this fully updated edition is an essential reference for anyone involved in viticulture and oenology who wants to explore new methods, understand different approaches, and refine existing practices.

Prof. Reynolds has had a long and distinguished career in Oenology. His career has included a position as Research Scientist for Agriculture Canada in British Columbia and, since 1997, a faculty position at Brock University. He is well known for his research into canopy management, the impacts of site and soil on flavour, irrigation and water relations, geomatics and the use of GPS/GIS and remote sensing for studying terroir. He is the author of over a hundred published articles and has been the editor of two award-winning titles on wine science.
