Long Island is home to some of the best grape growing conditions in the world.

Thanks to its coastal location, ocean breezes help to moderate temperatures at any time of the year. Winter temperatures are significantly milder than most of the state of NY, the coldest month is January with average temperatures of 30°f to 35°f and the warmest month is July with average temperatures of 70°f to 80°f.

The first vine in Martha Clara Vineyards was planted in 1996 and currently the vineyard area is composed by 87 acres, divided in 14 different grape varieties.

At Martha Clara Vineyards, wine is mostly made in the vineyard.

A hard-working team of vineyard personnel results in high quality grapes, and therefore competitive wines. Grapes are not harvested until they are at their optimal ripeness in order to extract the best possible expression from them.

Most of our wines are made from a single varietal, allowing the consumer to compare and choose their favorite wines.
