The Finger Lakes AVA is an American Viticultural Area located in Upstate New York, south of Lake Ontario. The Finger Lakes encompass eleven glacial lakes, but the area around Canandaigua, Keuka, Seneca, and Cayuga Lakes contain the vast majority of vineyard plantings in the AVA. Cayuga and Seneca Lakes each have their own American Viticultural Areas completely contained within the Finger Lakes AVA (Cayuga Lake AVA and Seneca Lake AVA). The Finger Lakes AVA includes 11,000 acres (4,452 ha) of vineyards, making it New York State's largest wine growing region. The Finger Lakes AVA wine region is often compared to the Rhine wine growing region of Germany. Riesling, one of the most important commercial grape varietals grown in Germany, is also one of the most successful grape varieties grown in the Finger Lakes AVA. Viticulturists in the Finger Lakes region grow a wide variety of grapes besides Riesling, including other European Vitis vinifera grapes, native American grapes, as well as French-American hybrid varieties.
