Long Island AVA: The Long Island AVA is an American Viticultural Area encompassing Nassau and Suffolk counties of New York, including the smaller offshore islands in those counties.  The AVA was established in 2001, over 15 years after two smaller AVAs were created at the eastern end of Long Island.  The Long Island AVA designation was promoted as a benefit for some wineries located just outside the two smaller AVAs and for wineries that wanted to create wines that use blends from vineyards in different parts of the island.  It was also developed and promoted as a consumer protection of the Long Island name; AVAs require that a minimum of 85% of the fruit used in the designated wine is grown within the borders of the region.  The "Long Island" AVA was authored by veteran Long Island winemaker Richard Olsen-Harbich who also authored the "The Hamptons, Long Island" and "North Fork of Long Island" AVAs in the mid-1980s.
