If you plan to visit Long Island vineyards, make sure to add Martha Clara’s Vineyard to your list.  Martha Clara’s Vineyard on the North Fork of Long Island was purchased by the Entenmann’s family in 1978 and was originally a potato farm.  In 1995, they caught the “grape bug” and planted 18 acres of vitis vinifera grapes and they haven’t looked back since.  Over the next four years, they expanded to over 100 acres of growing grapes and the vineyard is just lovely. 
In addition to growing grapes, Martha Clara’s Vineyard has a variety of activities that are just perfect for a romantic getaway to the wine country of Long Island.  Horse drawn carriage tours and wine tastings are available on an ongoing basis.  The August and September calendar of events are chock full and are as follows:
