The Hamptons, Long Island AVA is an American Viticultural Area located entirely within eastern Suffolk County, New York, and includes the entire South Fork of Long Island and the townships of Southampton and East Hampton. Authored by winemaker Richard Olsen-Harbich in 1984, it was the first AVA to be approved for Long Island. The region covers an east-west oriented peninsula approximately 54 miles (87 km) long and between 0.5 miles (0.8 km) and 10.0 miles (16.1 km) wide.
