Old and new world viticulture share a lot in common and knowledge and practices flow easily between them.  Often the best wines are a result of a blended approach of modern technology and traditional methods.  While the Mid-Atlantic climate may be more European, there is little doubt that progressive viticulture ideas and practices developed in arid areas such as California may be intelligently adapted to our conditions.  I believe that most viticulture best practices are the same around the world but it is the small portion of local knowledge and experience that makes any particular vineyard capable of producing high quality grapes.  That information for your vineyard may reside in one of these articles.  Better yet, travel and experience the world of viticulture yourself.
