This paper describes the history of disasters that have generated widespread losses among the vineyards of established regions of wine production. Recent events in the United States, Europe, and South Africa have highlighted the temporary and long-term implications of meteorological events and conditions that produced late-spring freezes, regional wildfires, hail, and floods. Hail, floods, and freeze events can set back or destroy grapevine growth for a season. Wildfires can not only incinerate not only a single crop, but can destroy vines themselves. Smoke from fires, even distant from the vineyards can taint grapes and render them useless. An archival database is developed to characterize, assess, and distinguish the events that have disrupted and diminished regional wine production in Europe, North and South America, South Africa, New Zealand, and Australia for single or multiple seasons. The evaluation reveals the trends in disasters and the implications of changing regional climates and underscores the tensions created by attempts to heighten grape quality.by vineyard encroachment in risky settings.
