This book is a scientific analysis of the soil and climatic factors affecting wine grape production, and thus, ultimately, wine itself. It provides a reasoned basis for the term 'terroir', and critically examines the science of climate change and how it could affect viticulture and winemaking. Dr John Gladstones is an internationally recognised authority on climate and viticulture, and among other achievements was instrumental in the establishment of the Margaret River wine district in Western Australia.
