Grape and Wine Industry

Napa is one of California’s smaller counties, with an area of 500,000 acres and only about 0.4% of California’s labor force and personal income. Yet it has earned a worldwide reputation for quality.

Fine wine and fine wine grapes are overwhelmingly the source of Napa’s prosperity and prominence. Napa’s unique terrain and climate and its high standards of viticulture and winemaking ensure premium pricing for its grapes and wine.

Napa produces only 4% of California’s wine by volume. But, as the largest producer of high-end wines in the state, Napa delivers almost 27% of the sales value of the state’s wine. With its premium grapes and top quality wines, Napa claims almost 21% of the total economic impact of wine in California.

  • The full economic impact of the wine and vineyard sector in Napa County totals $9.5 billion.
  • The wine and vineyard sector is easily Napa’s largest employer. Napa’s wine and vineyard sector directly, and indirectly through the services and products they consume or generate, provides nearly 40,000 jobs in Napa, nearly half of the county’s total employment.
  • These jobs generate wages of nearly $1.4 billion.
  • Sales revenues of Napa appellation wines exceed $2.3 billion. Wine made in the county with grapes from other regions adds many millions in revenue to that figure. (Source: Napa Valley Vintners, Economic Impact of Wine and Vineyards in Napa County, MKF Research, 2005)


The tourism industry is an extremely important part of what makes Napa County such a vibrant and economically progressive community. The average visitor to Napa County spends $197 per day with those staying over-night spending $233 per day. The visitors’ spending impacts almost every segment of the county’s economy in a significant way with almost one billion dollars in direct spending and $1.3 billion in total impact. Over 17,000 jobs are created which provide nearly half a billion dollars in income to residents. (Source: Napa County Economic Impact Study, March 2006)
