In January 1973, Louisa Thomas Hargrave and Alex Hargrave bought a potato farm in Cutchogue. Four years later, they released the first wine from Hargrave Vineyard.

In the decades since, more than 40 wineries and vineyards have opened on the East End of Long Island. Pindar, Lenz, Bedell, Paumanok, Palmer and Castello di Borghese, the successor to Hargrave, are among the North Fork veterans still producing wines.

And there has been a boomlet in newcomers since the millennium. Many are the family-run, boutique variety. Vineyards grow grapes, wineries make wine. Here's a taste.
