The Hamptons, Long Island is an American Viticultural Area (AVA) located entirely within eastern Suffolk County, New York, and includes the entire South Fork of Long Island and the townships of Southampton and East Hampton including Gardiners Island. It was established as the nation's 77th, the state's fourth and the island’s initial wine appellation on May 16, 1985 by the Bureau of Alcohol, Tobacco and Firearms (ATF), Treasury after reviewing the petition, authored by winemaker Richard Olsen-Harbich, and submitted by Mr. Lyle Greenfield, owner of the Bridgehampton Winery of Bridgehampton, for the land area of the South Fork of Eastern Long Island known as "The Hamptons, Long Island."
The appellation extends on Long Island’s east–west oriented peninsula approximately long and between and wide. The Hamptons AVA encompasses of land that is bounded on the south and east by the Atlantic Ocean. To the north is Peconic Bay which separates the North Fork peninsula from The Hamptons. To the west lies the remainder of Long Island where the two forks border each other. At the outset, there was of vinifera grapes cultivated and one bonded winery within the viticultural area. However, as of 2025, there are three wineries and vineyards in The Hamptons. The local climate is heavily influenced by the nearby Atlantic Ocean and Peconic Bay where the region is generally cooler and more prone to fog than the northern North Fork of Long Island viticultural area. The soil is generally silt and loam.
History The first English settlers arrived around 1640 to the area now known as The Hamptons. The first town to be established in this area was Southampton which was so named for Henry Wriothesly who was the Earl of Southampton, England. The towns of East Hampton, Bridgehampton, Westhampton and Hampton Bays were established by the late eighteenth century. This area thereafter became known as "The Hamptons," obviously due to the common ending of the major town names and a desire to preserve the area's English heritage. Today this name is commonly used to describe the locality. This is evident by the many publications, businesses and landmark descriptions which use the name "The Hamptons" to distinguish this region from the rest of Long Island, New York. For more than 300 years, The Hamptons have been a productive agricultural growing region. Wine grapes had been introduced to Eastern Long Island as early as the 18th Century. Records indicate that vineyards were flourishing in Southampton during Colonial times. Most of the grapes planted in The Hamptons region prior to the 20th Century were cultivated in relatively small vineyards; the grapes and wine which resulted from them were used principally for private consumption. Many of the local Indians, however, may have actually tended vineyards several hundred years earlier. However, in 1979, the tradition of grape-growing in The Hamptons region once again came into focus with the installation of two vinifera grape plantings. It was in this year that Lyle Greenfield of Bridgehampton and Ken Conrad of Sag Harbor each planted their own vineyard of vinifera wine grapes in Bridgehampton and Water Mill, respectively. The Bridgehampton Winery, with presses in The Hamptons viticultural area,, released two wines for sale in 1983 (Chardonnay and Riesling). At the outset, there was of grapes growing in the viticultural area of which are located near the Atlantic Ocean at Sagaponack in the Town of Southampton. All of the grapes are vinifera grapes and almost all of them are now producing a crop. According to the petitioner The Hamptons region had potential for vineyard expansion. Current growers were making more land available to them for potential vineyard expansion. In addition, there are still hundreds of acres of prime farmland in The Hamptons region that are available for the planting of grapes in the future All of the grapes are vinifera grapes and almost all of them are now producing a crop.

Terroir Topography and Climate Although The Hamptons and the North Fork are relatively close together, there are many climatic differences which exist between them. These differences are due to the unique topography of the eastern end of Long Island and the relation of the two forks to the Atlantic Ocean. Most of the climatic data for the eastern end of Long Island is recorded mainly from three weather stations: The Cornell Experimental Station in northern Riverhead (located on the North Fork), the Greenport weather station (located on the North Fork), and the Bridgehampton weather station in The Hamptons (located on the South Fork). The Cornell Station at Riverhead has been recording weather data since the 1950's, while the Bridgehampton Station has been operating for almost half a century. There are definite climatic differences which exist between the two forks. The winter months are colder on the North Fork. There the colder temperatures average colder than The Hamptons. The reason is that the North Fork is further away from the Atlantic Ocean and hence does not receive the warmed southwest ocean winds that The Hamptons receive. In the winter, the prevailing winds from the southwest are warmed by the Atlantic Ocean. The ocean in the winter has a buffering effect due to its accumulation of heat from the summer and fall months. This wind will therefore buffer the temperature of The Hamptons as it passes over them, however, by the time the wind passes over the colder Peconic Bay and reaches the North Fork, it has lost much of its warmth and hence does little to buffer the temperatures of the North Fork.
By the time spring arrives on Long Island, the ocean has cooled somewhat from the low winter temperatures. Breezes coming from the south at this time of year will therefore become cooled by the ocean, and as they pass over the warming land, a fog will often be produced. This fog will often become trapped on The Hamptons due to the many hills and rolling areas which exist there. Therefore, in the springtime, the North Fork will usually have more sunshine earlier and also have a higher average temperature. This is evident by the fact that the strawberries, sweet corn and potatoes grown on the North Fork begin to grow and ripen earlier than those same crops grown in The Hamptons.
During the summer months the southern breezes coming off the cool ocean will continue to keep average temperatures of The Hamptons lower. As the winds pass over The Hamptons, they travel over the Peconic Bay, which is a smaller body of water and hence warmer. The winds absorb much of the warmth from the bay and therefore cause the average temperatures on the North Fork to be higher than The Hamptons during the summer months. During the summer, the North Fork receives a greater number of thunder and lightning storms. These storms usually arrive from the west, and are pushed over towards the North Fork by the prevailing southeast winds. During the fall, The Hamptons can also expect cooler temperatures than the North Fork, especially during the night. Otherwise, both forks have the benefit of enjoying a fall season consisting of a lot of sunshine and normal amounts of precipitation.
The ocean effect, which alters the climates of both the North and South Fork is considerably reduced west of Riverhead, where the island widens. It is this reason along with the increased blending of soil series, which would keep either fork from being considered part of a larger Long Island appellation. Although the amount of sunshine and rainfall can have an effect on the length of the growing season, the single most important factor is the number of days between the spring and fall frosts. In data taken from the Riverhead Station on the North Fork and from the Bridgehampton Station in The Hamptons (South Fork), there are definite differences in the frost dates for both forks. During the 6-year period from 1978-1983 the number of days between frosts, or the length of the growing season averaged 195 days on the North Fork and 182 days in The Hamptons. During those years there were anywhere from 1 to over 3 weeks less time for the growing season in The Hamptons as compared to the North Fork.
When this data is further examined, it is seen that this difference occurs mostly between the dates of the last spring frost. The average last frost in The Hamptons is usually around April 23rd, while that on the North Fork occurs around the beginning of April. This spring difference is much greater than the difference between the first fall frosts, which usually occur during the end of October to the beginning of November on both forks. This supports the fact that the growing season gets off to a slower start in The Hamptons. The use of heat summation of "Growing Degree Days" is also another standard for determining climatic differences in grape-growing areas. Heat-summation is a standard developed by the University of California at Davis, and it is the measurement of the mean monthly temperatures of a single area, above 500 F. The average number of degree days for the North Fork (at Riverhead) and The Hamptons (at Bridgehampton) are as follows: Riverhead (1941-1970) - 2,932 Bridgehampton (1941-1970) - 2,531
