Title: Hops
Content:  Hops production is concentrated in moist temperate climates, with much of the world's production occurring near the 48th parallel north. Hop plants prefer the same soils as potatoes and the leading potato-growing states in the United States are also major hops-producing areas; however, not all potato-growing areas can produce good hops naturally: soils in the Maritime Provinces of Canada, for example, lack the boron that hops prefer. Historically, hops were not grown in Ireland, but were imported from England. In 1752 more than 500 tons of English hops were imported through Dublin alone. Important production centres today are the Hallertau in Germany, the Žatec (Saaz) in the Czech Republic, the Yakima (Washington) and Willamette (Oregon) valleys, and western Canyon County, Idaho (including the communities of Parma, Wilder, Greenleaf, and Notus). The principal production centres in the UK are in Kent (which produces Kent Goldings hops), Herefordshire, and Worcestershire. Essentially all of the harvested hops are used in beer making.

Content:  The United States of America is the world's largest producer of hops, the flowers of female Humulus lupulus plants. The primary use of hops grown in the United States is in brewing. In 2019, the U.S. accounted for 40% of world hop production and 39% of world hop acreage.
Title: Hop production in the United States
Content:  Dutch and English settlers of the New England colonies began importing hops for brewing and medicinal use as early as the 17th century. The Massachusetts Company began commercially growing hops for colonial brewing in 1629. European hop rhizomes were later brought to the west coast by Wilson G. Flint in 1850 during the California Gold Rush period. Commercial hop production in California began in 1854 in order to satisfy a growing demand for beer given the large influx of immigrant miners and farmers that were settling in the state. As the hop industry expanded on the west coast, hop production on the east coast began to centralize in New York during the 1880s. However, it diminished at the hands of several waves of disease and reduced demand for hops as a result of prohibition. Furthermore, hop growth nationwide faced a steep decline with Prohibition, shrinking large growing regions into small pockets along the west coast, primarily in the Pacific Northwest. Following the devastating effects of two world wars in Europe, American hop growers of the Pacific Northwest would reemerge as a main competitor in the world hop market.
Title: Hops
Content:   Although hops are grown in most of the continental United States and Canada, cultivation of hops for commercial production requires a particular environment. As hops are a climbing plant, they are trained to grow up trellises made from strings or wires that support the plants and allow them significantly greater growth with the same sunlight profile. In this way, energy that would have been required to build structural cells is also freed for crop growth. The hop plant's reproduction method is that male and female flowers develop on separate plants, although occasionally a fertile individual will develop which contains both male and female flowers. Because pollinated seeds

Content:  Washington is the largest hop producing state in the country. Hops were first introduced to the Yakima Valley in the late nineteenth century, where farmers soon recognized their ability to flourish in the high desert climate.
Title: Hop production in the United States
Content:  Hop farms in the Pacific Northwest region comprise approximately 96% of total United States hop acreage. One acre of hops consists of 889 plants, each of which can produce upwards of two pounds of cones. Hop acreage is categorized by alpha, aroma, and dual purpose type and further divided by varietals. Since 2011, aroma varietal acreage has increased at a rapid rate, likely due to the popularization of American IPA beer styles and an increased demand for new aroma profiles in beer. Optimal climate, availability of water, and proper soil type combine to make the Yakima Valley and other Northwestern regions ideal locations for growing hop bines. Hops require large amounts of sunlight in order to grow effectively and thus grow best within the 30th and 50th parallels. Many hop farms have been family owned and operated for several generations.

Content:  were first grown in the southeast of England (Kent), when they were introduced as an agricultural crop by Dutch farmers. Consequently many words used in the hop industry derive from the Dutch language. Hops were then grown as far north as Aberdeen, near breweries for convenience of infrastructure. According to Thomas Tusser's 1557 Five Hundred Points of Good Husbandry: "'The hop for his profit I thus do exalt, It strengtheneth drink and it flavoureth malt; And being well-brewed long kept it will last, And drawing abide, if ye draw not too fast.'" In England there were many complaints over the quality of imported hops, the sacks of

Content:  The United States exports hops worldwide. The largest importers of U.S. hops include Belgium, Canada, the United Kingdom, Germany, and Brazil.
Title: Humulus japonicus
Content:  The Japanese hop can adapt well to new environments. Its range and distribution in North America prove that it can thrive in a wide range of environments, from the southern regions of the U.S. to the far reaches of northern Canada. It can grow and cover any area quickly. Thousands of hop plants can grow in one acre, and they can blanket a majority of the local vegetation. The vines grow rapidly during the summer, climbing up and over everything in their path, and can form dense mats several feet deep, blocking light to whatever plants are underneath.
