Wine

Board’s

Vision

2015A Strategic Direction for the Virginia Wine Industry

Virginia’s Viticultural GIS will support the Industry as it seeks to:

• Improve the quality and uniqueness of Virginia wines by allowing for increased specificity

of site selection

• Enhance the image and reputation of Virginia wines and the Virginia wine industry through

value‐added regional branding

• Increase and ex and the market share of Vir inia wine sold in state national and international markets through the increased visibility provided by this user‐friendly online

GIS

• Improve the profitability of vineyard and wine businesses in Virginia by providing vineyard

‐

• Maintain (enhance) Virginia's rural character and beauty through the expansion of Virginia's

wine industry by providing an educational tool to remove perceived barriers to the

establishment of new vineyards
