International Forum on Climate Prediction, Agriculture and Development
California produces 90% of all wine within the U.S. and dominates the $33 billion/year domestic retail wine industry. Since the 1950s, wine grape growers in California have seen dramatic increases in premium wine quality, grape yield, and crop value. Advances in viticultural practices (irrigation, nutrition, pest/disease control, trellising etc.) and experience in wine making have certainly contributed to the success (Jackson and Lombard 1993). In spite of such advances, wine growers generally believe climate plays a significant role in determining the quantity and quality of a given vintage.
