Grapes native to Long Island

[wondersofwine]

Foodie has experience with vineyards in New York--Finger Lakes area I think. He may respond to your query. Meantime, I have to question the use of "indigenous." I thought that meant native to the area and Pinot Noir and Sauvignon Blanc grapes may be grown in New York but they aren't "native" American varieties. Clones used in America probably came from Europe.
