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
