The North Fork of Long Island AVA is an American Viticultural Area located in eastern Suffolk County, New York.
The North Fork of Long Island is home to over 40 wineries and 3,000 acres (1,200 ha) of planted vineyards.
The local climate is heavily influenced by the presence of Long Island Sound, Peconic Bay, and the Atlantic Ocean.
The maritime influences of these bodies of water help to moderate temperature fluctuations and extend the growing season up to a month longer than other regions in New York.
The largest contiguous planting of Pinot Blanc in the United States is on the North Fork of Long Island AVA at Suhru & Lieb Vineyards on Oregon Road in Cutchogue, New York.
