The Finger Lakes AVA is an American Viticultural Area located in Upstate New York, south of Lake Ontario. It was established in 1982 and encompasses the eleven Finger 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. The Finger Lakes AVA includes 11,000 acres (4,452 ha) of vineyards and is the largest wine-producing region in New York State.

The Seneca Lake AVA is an American Viticultural Area around Seneca Lake in Upstate New York. The wine appellation is entirely contained within the larger Finger Lakes AVA, and includes portions of Ontario, Schuyler, Seneca, and Yates counties. Seneca Lake is a glacial lake about 35 miles (56 km) long and up to 600 feet (180 m) deep. The lake does not freeze in winter, and acts as a giant heat storage unit for the vineyards surrounding the lake, extending the growing season. The most commercially important grape variety in the region is Riesling, although a wide variety of Vitis vinifera and French hybrid grapes are grown.
