Cornell's viticulture extension programs draw on the resources of research programs in viticulture, grape breeding, plant pathology, entomology, and applied economics and management to deliver research-based information supporting profitability and growth of vineyards and wineries across New York State.
One statewide and four regional viticulture extension programs develop educational programs and communicate with the industry through electronic and print newsletters, conferences, field meetings, and applied research projects in commercial vineyards.
The Finger Lakes Grape Program, based at Cornell Cooperative Extension of Yates County, in Penn Yan, New York, covers a five-county area in the Finger Lakes, encompassing 9,000 acres of over 30 varieties of grapes and over 100 wineries.
The Lake Erie Regional Grape Program is a joint extension program of Cornell and Penn State University. Based at the new Cornell Lake Erie Research and Extension Laboratory in Portland, NY, the program covers three western New York counties and Erie County in Pennsylvania.
