Washington State ranks second only to California in the production of Vitis vinifera L. grapes, for the production of premium table wines in the United States. From early plantings at Fort Vancouver in 1825 to an industry with over 68,000 acres, Washington State is making a name for itself. Currently, the economic impact to the state’s economy is ~ $8.6 billion dollars. There are over 750 wineries, and still more are being planned. Current acreage of wine grapes is over 43,000 acres and Washington State currently¬†produces approximately 12 million cases of wine per year.

Washington State also has a large Concord grape juice industry, made from the grape Vitis labruscana. Most of the production is destined for jams, jellies, and of course, grape juice. The acreage of Concord in Washington State is stable at ~25,000 acres. Washington State is the #1 producer of Concord grapes, followed by New York, Pennsylvania, Ohio, and Southwest Michigan.
