Percy Dougherty, PhD in Geology and Physical Geography with a specialty in limestone landforms, has taught wine classes at NCC since 2008. While researching caves, he noticed many great wines grow on limestone. His research shifted to the impact of the environment on wine or what the French call terroir. As Professor Emeritus at Kutztown University, he retired from full time teaching, but he is still active in presenting papers and workshops for the Association of American Geographers. He is the founder and first President of the Wine Specialty Group of the Association of American Geographers and recently published a book entitled The Geography of Wine: Regions, Terroir and Techniques. He is a Graduate Wine Judge in the American Wine Society and serves as President of the Lehigh Valley Chapter.
