The global wine market is undergoing a profound transformation, after years of stable behavior that, however, heralded the perfect storm unleashed in recent years. For a careful observer, the seeds of change have been there for many years, as the contributions collected in this volume demonstrate. The authors present the evolution of supply, demand, and trade in international wine markets for each of the main wine-producing countries — the United States, Australia, Spain, France, and Italy — and analyze the causes of this change and potential economic intervention policies.
