Which state accounts for about 90% of US wine production?

• A. Oregon
• B. New York
• C. Washington
• D. California

Answer: (D)

California dominates US wine production because its large scale of vineyards, favorable and varied climates, and well-developed winemaking infrastructure support high-volume grape growing and winemaking. The state's extensive grape acreage, especially in regions like the Central Valley and the maritime-influenced coastal areas, combined with reliable irrigation and established industry practices, enables production to reach a level far beyond other states. This is why California accounts for about 90% of US wine production. Oregon and New York produce notable wines, but in far smaller volumes, and Washington, while a major producer, remains well behind California in total output.
