The flowers are dark pink, with very distinct reflexed petals, leaving the style and stamens fully exposed and pointing forward. They are pollinated by bees. The fruit is a berry that is larger than the leaves of the plant; it is initially light green, turning red when ripe.{{Cite web |last=Keith |first=Gabriel |title=Cranberries: A colorful and nutritious fruit |url=https://extension.sdstate.edu/cranberries-colorful-and-nutritious-fruit |access-date=20 October 2023 |publisher=South Dakota State University Extension |language=en-us}} It has an acidic taste which usually overwhelms its sweetness.

There are 4–5 species of cranberry, classified by subgenus:{{cite web|url=https://www.britannica.com/plant/cranberry|title=Encyclopaedia Britannica: Cranberry|date=23 October 2023 }}

Cranberries are related to bilberries, blueberries, and huckleberries, all in Vaccinium subgenus Vaccinium. These differ in having bell-shaped flowers, petals that are not reflexed, and woodier stems, forming taller shrubs.

American Revolutionary War veteran Henry Hall first cultivated cranberries in the Cape Cod town of Dennis around 1816. In the 1820s, Hall was shipping cranberries to New York City and Boston from which shipments were also sent to Europe. In 1843, Eli Howes planted his own crop of cranberries on Cape Cod, using the "Howes" variety. In 1847, Cyrus Cahoon planted a crop of "Early Black" variety near Pleasant Lake, Harwich, Massachusetts.File:Cranberry farm.jpg

Cranberries have had two major breeding events. The first occurred in the 1920s, with aims to create a crop that was more insect-resistant, specifically to blunt-nosed leafhopper (Limotettix vaccini), the vector of cranberry false blossom disease. This resulted in cultivars such as "Stevens" and "Franklin". As such, cultivars like "Howes" tend to be more susceptible to insects than "Stevens". However, with the introduction of many broad-spectrum pesticides in the 1940s and 1950s, breeders eventually stopped breeding for pest resistance. Instead, beginning in the 1980s, cranberries were bred for high-yielding varieties, leading to cultivars such as "Crimson Queen" and "Mullica Queen". Many of these varieties were spearheaded and bred by Dr. Nicholi Vorsa of Rutgers University.{{cite web |date=23 December 2024 |title=Rutgers Cranberries |url=https://research.rutgers.edu/agricultural-products/cranberries#varieties |access-date=23 December 2024 |publisher=Rutgers University Office of Research}} In more recent years, there have been heavier restrictions on pesticides due to environmental safety concerns, leading to a greater emphasis on high yield, high resistance varieties.

Historically, cranberry beds were constructed in wetlands. Today's cranberry beds are constructed in upland areas with a shallow water table. The topsoil is scraped off to form dykes around the bed perimeter. Clean sand is hauled in and spread to a depth of {{convert|10|to|20|cm|in|0|sp=us}}. The surface is laser leveled flat to provide even drainage. Beds are frequently drained with socked tile in addition to the perimeter ditch. In addition to making it possible to hold water, the dykes allow equipment to service the beds without driving on the vines. Irrigation equipment is installed in the bed to provide irrigation for vine growth and for spring and autumn frost protection.

A common misconception about cranberry production is that the beds remain flooded throughout the year.{{Cite news |last=Morales |first=Christina |date=17 November 2022 |title=How Jellied Cranberry Sauce Is Made |url=https://www.nytimes.com/2022/11/17/dining/canned-jellied-cranberry-sauce-thanksgiving.html |url-status=live |archive-url=https://web.archive.org/web/20240117053845/https://www.nytimes.com/2022/11/17/dining/canned-jellied-cranberry-sauce-thanksgiving.html |archive-date=17 January 2024 |access-date=24 June 2024 |work=The New York Times}}{{Cite news |last=Hutton |first=Rachel |date=16 November 2023 |title=There's only one cranberry farm in Minnesota, and it's run by a 21-year-old woman and her brother |url=https://www.startribune.com/cranberry-harvest-minnesota-wisconsin-ocean-spray-forster/600320148/ |access-date=24 June 2024 |work=Star Tribune}} During the growing season cranberry beds are not flooded, but are irrigated regularly to maintain soil moisture.

When ice forms on the beds, trucks can be driven onto the ice to spread a thin layer of sand to control pests and rejuvenate the vines. Sanding is done every three to five years.

Cranberry vines are propagated by moving vines from an established bed. The vines are spread on the surface of the sand of the new bed and pushed into the sand with a blunt disk. The vines are watered frequently during the first few weeks until roots form and new shoots grow. Beds are given frequent, light application of nitrogen fertilizer during the first year.{{cite web |author1=Carolyn J. DeMoranville |author2=Hilary A. Sandler |author3=Frank L.

File:Harvesting cranberries 2.jpg

Cranberries are harvested in the fall when the fruit takes on its distinctive deep red color, and most ideally after the first frost.{{Cite book|last=Angier|first=Bradford|url=https://archive.org/details/fieldguidetoedib00angi/page/66/mode/2up|title=Field Guide to Edible Wild Plants|publisher=Stackpole Books|year=1974|isbn=0-8117-0616-8|location=Harrisburg, PA|pages=66|oclc=799792|author-link=Bradford Angier}} This is usually in September through the first part of November. Berries that receive sun turn a deep red when fully ripe, while those that do not fully mature are a pale pink or white color. To harvest cranberries, the beds are flooded with {{convert|15|to|20|cm|in|sp=us|0}} of water above the vines. A harvester is driven through the beds to remove the fruit from the vines. For the past 50 years{{when|date=November 2023}}, water reel type harvesters have been used. Harvested cranberries float in the water and can be corralled into a corner of the bed and conveyed or pumped from the bed. From the farm, cranberries are taken to receiving stations where they are cleaned, sorted, and stored prior to packaging or processing. While cranberries are harvested when they take on their deep red color, they can also be harvested beforehand when they are still white, which is how white cranberry juice is made.{{Cite web|url=https://stonebridgefarmevents.com/wet-picking/|title=Wet Picking|website=Stone Bridge Farm|access-date=7 May 2019|archive-date=7 May 2019|archive-url=https://web.archive.org/web/20190507021146/https://stonebridgefarmevents.com/wet-picking/|url-status=dead}} Yields are lower on beds harvested early and the early flooding tends to damage vines, but not severely. Vines can also be trained through dry picking to help avoid damage in subsequent harvests.{{Cite web|url=http://www.umass.edu/cranberry/pubs/bmp_fruit.html|title=Fresh Fruit Production BMP: Publications UMass Cranberry Station|website=www.umass.edu|access-date=7 May 2019}}

Although most cranberries are wet-picked as described above, 5–10% of the US crop is still dry-picked. This entails higher labor costs and lower yield, but dry-picked berries are less bruised and can be sold as fresh fruit instead of having to be immediately frozen or processed. Originally performed with two-handed comb scoops, dry picking is today accomplished by motorized, walk-behind harvesters which must be small enough to traverse beds without damaging the vines.

Cranberries for fresh market are stored in shallow bins or boxes with perforated or slatted bottoms, which deter decay by allowing air to circulate. Because harvest occurs in late autumn, cranberries for fresh market are frequently stored in thick walled barns without mechanical refrigeration. Temperatures are regulated by opening and closing vents in the barn as needed. Cranberries destined for processing are usually frozen in bulk containers shortly after arriving at a receiving station.

{{main|List of Vaccinium diseases|label 1=List of Vaccinium diseases}}

Diseases of cranberry include:

• Cranberry fruit rot
• Cranberry root rot
• Cranberry false blossom disease, caused by a phytoplasma that is vectored by the blunt-nosed leafhopper (Limotettix vaccinii), and prevents the plant from creating fertile flowers and thus berries.

Probably due to the high phenolics and plant defenses, in addition to the harsh environments that cranberries are grown under (acid, sandy soils that get flooded every year), a majority of insect pests associated with cranberries are native to the cranberry's home range of North America. The top studied insect pests of cranberries include:

• Sparganothis sulfureana (Sparganothis fruitworm), a leafrolling moth
• Acrobasis vaccinii (cranberry fruitworm), a snout moth
• Rhopobota naevana (blackheaded fireworm), a leafrolling moth
• Choristoneura parallela (spotted fireworm), a leafrolling moth

All four of these top studied insect pests are direct pests, eating the berries.

Other well studied cranberry pests include:

• Limotettix vaccinii (blunt-nosed leafhopper), a leafhopper
• Lymantria dispar (spongy moth), an invasive moth
• Dasineura oxycoccana (cranberry tipworm), a gall-forming midge
• Chrysoteuchia topiarius (cranberry girdler), a snout moth
• Anthonomus musculus (cranberry weevil), a weevil
• Systena frontalis (red-headed flea beetle), a flea beetle
• Otiorhynchus sulcatus (black vine weevil), an invasive weevil
• Anomala orientalis (oriental beetle), an invasive scarab beetle

As more and more pesticides become banned due to environmental concern, there are increased resurgences of secondary pests.

In 2022, world production of cranberry was 582,924 tonnes, with the United States and Canada together accounting for 99% of the total.{{cite web|url=http://www.fao.org/faostat/en/#data/QC|title= Cranberry production in 2022, Crops/Regions/World list/Production Quantity/Year (pick lists)|year=2024|publisher=UN Food and Agriculture Organization, Corporate Statistical Database (FAOSTAT)|access-date=1 July 2024}} Wisconsin (59% of US production) and Quebec (60% of Canadian production) are two of the largest producers of cranberries in the two countries.{{cite web |author1=Ronda Payne |title=Crazy for cranberries in Canada |url=https://www.fruitandveggie.com/crazy-for-cranberries-in-canada-20713/ |publisher=Fruit & Vegetable, Annex Business Media |access-date=28 May 2022 |date=2 July 2019}} Cranberries are also a major commercial crop in Massachusetts, New Jersey, Oregon, and Washington,{{cite web |title=Cranberry cultivation |url=http://www.uscranberries.com/about-cranberries/cultivation/ |publisher=US Cranberries |access-date=18 October 2018 |date=2018}} as well as in the Canadian province of British Columbia (33% of Canadian production).

The anticoagulant effects of warfarin may be increased by consuming cranberry juice, resulting in adverse effects such as increased incidence of bleeding and bruising.{{cite journal |vauthors=Pham DQ, Pham AQ |date=March 2007 |title=Interaction potential between cranberry juice and warfarin |journal=Am J Health Syst Pharm |volume=64 |issue=5 |pages=490–4 |doi=10.2146/ajhp060370 |pmid=17322161}} Other safety concerns from consuming large quantities of cranberry juice or using cranberry supplements include potential for nausea, and increasing stomach inflammation, sugar intake or kidney stone formation.

Raw cranberries are 87% water, 12% carbohydrates, and contain negligible protein and fat (table). In a 100 gram reference amount, raw cranberries supply 46 calories and moderate levels of vitamin C, dietary fiber, and the essential dietary mineral manganese, each with more than 10% of its Daily Value. Other micronutrients have low content (table).

Dried cranberries are commonly processed with up to 10 times their natural sugar content.{{cite web |date=2018 |title=Cranberries, dried (survey) |url=https://fdc.nal.usda.gov/fdc-app.html#/food-details/1102630/nutrients |accessdate=25 April 2021 |publisher=FoodData Central, US Department of Agriculture |archive-date=3 April 2019 |archive-url=https://web.archive.org/web/20190403171801/https://fdc.nal.usda.gov/fdc-app.html#/food-details/1102630/nutrients |url-status=dead }} The drying process also eliminates vitamin C content.

In North America, the Narragansett people of the Algonquian nation in the regions of New England appeared to be using cranberries in pemmican for food and for dye. Calling the red berries, sasemineash, the Narragansett people may have introduced cranberries to colonists in Massachusetts. In 1550, James White Norwood made reference to Native Americans using cranberries, and it was the first reference to American cranberries up until this point.{{Cite journal |last1=Broussard |first1=Melissa |last2=Rao |first2=Sujaya |last3=Stephen |first3=William P. |last4=White |first4=Linda |date=June 2011 |title=Native Bees, Honeybees, and Pollination in Oregon Cranberries |journal=HortScience |volume=46 |issue=6 |pages=885–888 |doi=10.21273/hortsci.46.6.885 |issn=0018-5345 |doi-access=free}} In James Rosier's book The Land of Virginia there is an account of Europeans coming ashore and being met with Native Americans bearing bark cups full of cranberries. In Plymouth, Massachusetts, there is a 1633 account of the husband of Mary Ring auctioning her cranberry-dyed petticoat for 16 shillings. In 1643, Roger Williams's book A Key into the Language of America described cranberries, referring to them as "bearberries" because bears ate them. In 1648, preacher John Elliott was quoted in Thomas Shepard's book Clear Sunshine of the Gospel with an account of the difficulties the Pilgrims were having in using the Indians to harvest cranberries as they preferred to hunt and fish. In 1663, the Pilgrim cookbook appears with a recipe for cranberry sauce. In 1667, New Englanders sent to King Charles ten barrels of cranberries, three barrels of codfish and some Indian corn as a means of appeasement for his anger over their local coining of the pine tree shilling minted by John Hull.{{citation needed|date=March 2023}} In 1669, Captain Richard Cobb had a banquet in his house (to celebrate both his marriage to Mary Gorham and his election to the Convention of Assistance), serving wild turkey with sauce made from wild cranberries. In the 1672 book New England Rarities Discovered, author John Josselyn described cranberries, writing:

Sauce for the Pilgrims, cranberry or bearberry, is a small trayling{{sic}} plant that grows in salt marshes that are overgrown with moss. The berries are of a pale yellow color, afterwards red, as big as a cherry, some perfectly round, others oval, all of them hollow with sower{{sic|nolink=y}} astringent taste; they are ripe in August and September. They are excellent against the Scurvy. They are also good to allay the fervor of hoof diseases. The Indians and English use them mush, boyling{{sic|nolink=y}} them with sugar for sauce to eat with their meat; and it is a delicate sauce, especially with roasted mutton. Some make tarts with them as with gooseberries.

The Compleat Cook's Guide, published in 1683, made reference to cranberry juice. In 1703, cranberries were served at the Harvard University commencement dinner. In 1787, James Madison wrote Thomas Jefferson in France for background information on constitutional government to use at the Constitutional Convention. Jefferson sent back a number of books on the subject and in return asked for a gift of apples, pecans and cranberries. William Aiton, a Scottish botanist, included an entry for the cranberry in volume II of his 1789 work Hortus Kewensis. He notes that Vaccinium macrocarpon (American cranberry) was cultivated by James Gordon in 1760. In 1796, cranberries were served at the first celebration of the landing of the Pilgrims, and Amelia Simmons (an American orphan) wrote a book entitled American Cookery which contained a recipe for cranberry tarts.

Usually cranberries as fruit are cooked into a compote or jelly, known as cranberry sauce. Such preparations are traditionally served with roast turkey, as a staple of Thanksgiving (both in Canada and in the United States) as well as English dinners. The berry is also used in baking (muffins, scones, cakes and breads). In baking it is often combined with orange or orange zest. Less commonly, cranberries are used to add tartness to savory dishes such as soups and stews.

Fresh cranberries can be frozen at home, and will keep up to nine months; they can be used directly in recipes without thawing.{{cite web|url=http://researchguides.library.wisc.edu/content.php?pid=87646&sid=652165 |title=The American Cranberry-Basic Information on Cranberries |publisher=Library.wisc.edu |access-date=4 October 2010}}

There are several alcoholic cocktails, including the cosmopolitan, that include cranberry juice.

A 2023 Cochrane systematic review of 50 studies concluded there is evidence that consuming cranberry products (such as juice or capsules) is effective for reducing the risk of urinary tract infections (UTIs) in women with recurrent UTIs, in children, and in people susceptible to UTIs following clinical interventions; there was little evidence of effect in elderly people, those with urination disorders or pregnant women.{{Cite journal |last1=Williams |first1=Gabrielle |last2=Stothart |first2=Christopher I. |last3=Hahn |first3=Deirdre |last4=Stephens |first4=Jacqueline H. |last5=Craig |first5=Jonathan C. |last6=Hodson |first6=Elisabeth M. |display-authors=3|date=10 November 2023 |title=Cranberries for preventing urinary tract infections |journal=The Cochrane Database of Systematic Reviews |volume=2023 |issue=11 |pages=CD001321 |doi=10.1002/14651858.CD001321.pub7 |issn=1469-493X |pmc=10636779 |pmid=37947276}}

Cranberry sales in the United States have traditionally been associated with holidays of Thanksgiving and Christmas.

In the U.S., large-scale cranberry cultivation has been developed as opposed to other countries. American cranberry growers have a long history of cooperative marketing. As early as 1904, John Gaynor, a Wisconsin grower, and A.U. Chaney, a fruit broker from Des Moines, Iowa, organized Wisconsin growers into a cooperative called the Wisconsin Cranberry Sales Company to receive a uniform price from buyers. Growers in New Jersey and Massachusetts were also organized into cooperatives, creating the National Fruit Exchange that marketed fruit under the Eatmor brand. The success of cooperative marketing almost led to its failure. With consistent and high prices, area and production doubled between 1903 and 1917 and prices fell.

With surplus cranberries and changing American households some enterprising growers began canning cranberries that were below-grade for fresh market. Competition between canners was fierce because profits were thin. The Ocean Spray cooperative was established in 1930 through a merger of three primary processing companies: Ocean Spray Preserving company, Makepeace Preserving Co, and Cranberry Products Co. The new company was called Cranberry Canners, Inc. and used the Ocean Spray label on their products. Since the new company represented over 90% of the market, it would have been illegal under American antitrust laws had attorney John Quarles not found an exemption for agricultural cooperatives. {{as of|2006}}, about 65% of the North American industry belongs to the Ocean Spray cooperative.{{Cite book |url=https://www.umass.edu/resec/sites/default/files/19cranberryjan06_0.pdf |archive-url=https://web.archive.org/web/20150911024004/http://www.umass.edu/resec/sites/default/files/19cranberryjan06_0.pdf |archive-date=11 September 2015 |url-status=live |title=The Cranberry Industry and Ocean Spray Cooperative: Lessons in Cooperative Governance}}

In 1958, Morris April Brothers—who produced Eatmor brand cranberry sauce in Tuckahoe, New Jersey—brought an action against Ocean Spray for violation of the Sherman Antitrust Act and won $200,000 in real damages plus triple damages,{{Citation needed|date=October 2021}} just in time for the Great Cranberry Scare: on 9 November 1959, Secretary of the United States Department of Health, Education, and Welfare Arthur S. Flemming announced that some of the 1959 cranberry crop was tainted with traces of the herbicide aminotriazole. The market for cranberries collapsed and growers lost millions of dollars. However, the scare taught the industry that they could not be completely dependent on the holiday market for their products; they had to find year-round markets for their fruit. They also had to be exceedingly careful about their use of pesticides. After the aminotriazole scare, Ocean Spray reorganized and spent substantial sums on product development. New products such as cranberry-apple juice blends were introduced, followed by other juice blends.

Prices and production increased steadily during the 1980s and 1990s. Prices peaked at about $65.00 per barrel ({{convert|0.65|$/lb|$/kg|2 |disp=or}})—a cranberry barrel equals {{convert|100|lb|kg |sigfig=3 |disp=or|abbr=off}}—in 1996 then fell to $18.00 per barrel ({{convert|0.18|$/lb|$/kg|2|disp=or}}) in 2001. The cause for the precipitous drop was classic oversupply. Production had outpaced consumption leading to substantial inventory in freezers or as concentrate.{{citation needed|date=October 2021}}

Cranberry handlers (processors) include Ocean Spray, Cliffstar Corporation, Northland Cranberries Inc. (Sun Northland LLC), Clement Pappas & Co., and Decas Cranberry Products as well as a number of small handlers and processors.{{cite book |vauthors=Roper TR, Vorsa N |chapter=Cranberry: Botany and Horticulture |editor=Janick J |title=Horticultural Reviews |publisher=Wiley |location=New York |year=1997 |pages=215–6 |isbn=978-0-471-18907-7 |chapter-url=http://www.pubhort.org/hr/hr21/HR_21_07_00000000.pdf |archive-url=https://web.archive.org/web/20070614123603/http://www.pubhort.org/hr/hr21/HR_21_07_00000000.pdf |archive-date=14 June 2007 |url-status=live}}

The Cranberry Marketing Committee is an organization that was established in 1962 as a Federal Marketing Order to ensure a stable, orderly supply of good quality product.{{Cite web|title=About CMC » Cranberry Marketing Committee|url=https://www.uscranberries.com/about-cmc/|access-date=25 December 2021|website=Cranberry Marketing Committee|language=en-US|archive-date=25 December 2021|archive-url=https://web.archive.org/web/20211225150024/https://www.uscranberries.com/about-cmc/|url-status=dead}} The order has been renewed and modified slightly over the years. The market order has been invoked during six crop years: 1962 (12%), 1963 (5%), 1970 (10%), 1971 (12%), 2000 (15%), and 2001 (35%). Even though supply still exceeds demand, there is little will to invoke the Federal Marketing Order out of the realization that any pullback in supply by U.S. growers would easily be filled by Canadian production.

The Cranberry Marketing Committee, based in Wareham, Massachusetts, represents more than 1,100 cranberry growers and 60 cranberry handlers across Massachusetts, Rhode Island, Connecticut, New Jersey, Wisconsin, Michigan, Minnesota, Oregon, Washington and New York (Long Island). The authority for the actions taken by the Cranberry Marketing Committee is provided in Chapter IX, Title 7, Code of Federal Regulations which is called the Federal Cranberry Marketing Order. The Order is part of the Agricultural Marketing Agreement Act of 1937, identifying cranberries as a commodity good that can be regulated by Congress. The Federal Cranberry Marketing Order has been altered over the years to expand the Cranberry Marketing Committee's ability to develop projects in the United States and around the world. The Cranberry Marketing Committee currently runs promotional programs in the United States, China, India, Mexico, Pan-Europe, and South Korea.
