full_context: Document 1: Tzfat cheese: Tzfat cheese () is a semi-hard cheese produced in Israel originally from sheep's milk. It was first produced by the HaMeiri dairy in Safed ("Tzfat" in Hebrew) in 1840 and is still produced there by descendants of the original cheese makers.
Document 2: Alcohol laws of Wisconsin: The drinking age in Wisconsin is 21.

Document 3: National Minimum Drinking Age Act: The National Minimum Drinking Age Act of 1984 (23 U.S.C. § 158) was passed by the United States Congress on July 17, 1984. It was a controversial bill that punished every state that allowed persons below 21 years to purchase and publicly possess alcoholic beverages by reducing its annual federal highway apportionment by 10 percent. The law was later amended, lowering the penalty to 8 percent from fiscal year 2012 and beyond.
Document 4: Coon cheese: Coon cheese is named after its American creator, Edward William Coon (1871 -- 1934) of Philadelphia, who patented a method, subsequently known as the Cooning process, for fast maturation of cheese via high temperature and humidity. Former manufacturer Kraft, and later Dairy Farmers and National Foods, have vigorously defended the trademark.
Document 5: Hodag Country Festival: The Hodag Country Festival, founded in 1978, is an outdoor music festival held each summer in Rhinelander, in Oneida County, Wisconsin, United States. The 2020 festival is scheduled for July 9th thru the 12th, 2020. When the first festival was held August 4–6, 1978, it featured Freddy Fender and Jana Jae and had an attendance of about 500. It is named for the folkloric Hodag, first reported to exist in 1893 in Rhinelander.
Document 6: Colby cheese: In 1885, Joseph F. Steinwand developed a new type of cheese at his father's cheese factory near Colby, Wisconsin. The cheese was named after the village, which had been founded three years earlier. While Colby cheese is still widely available, it is no longer produced in Colby. A festival commemorating the cheese is held every year in mid-July where all local food booths offer free Colby cheese. On August 12, 2015, the original cheese factory was torn down leaving only the foundations of the building.
Document 7: Alcohol laws of New York: In response to the National Minimum Drinking Age Act in 1984, which reduced by up to 10% the federal highway funding of any state which did not have a minimum purchasing age of 21, the New York Legislature raised the drinking age from 19 to 21, effective December 1, 1985. (The drinking age had been 18 for many years before the first raise in 1984, to 19.) Persons under 21 are prohibited from purchasing alcohol or possessing alcohol with the intent to consume, unless the alcohol was given to that person by their parent or legal guardian. There is no law prohibiting where people under 21 may possess or consume alcohol that was given to them by their parents. Persons under 21 are prohibited from having a blood alcohol level of 0.02% or higher while driving.
Document 8: Cathare: Cathare is a goat's milk cheese from the Languedoc-Roussillon region of France. The cheese comes in flat discs whose face is covered in charcoal powder with the Occitan cross inscribed. Under the rind, Cathare is pure white with a soft, creamy texture. Its goat-milk flavor intensifies as it ages, and reaches its prime after two to three weeks, which makes it typically unavailable in the United States, due to the Food and Drug Administration's stance that raw milk soft cheeses can pose as a health risk. The sale of raw milk cheese aged under 60 days is illegal in the United States.
Document 9: Somerset: Towns such as Castle Cary and Frome grew around the medieval weaving industry. Street developed as a centre for the production of woollen slippers and, later, boots and shoes, with C. & J. Clark establishing its headquarters in the town. C&J Clark's shoes are no longer manufactured there as the work was transferred to lower-wage areas, such as China and Asia. Instead, in 1993, redundant factory buildings were converted to form Clarks Village, the first purpose-built factory outlet in the UK. C&J Clark also had shoe factories, at one time at Bridgwater, Minehead, Westfield and Weston super Mare to provide employment outside the main summer tourist season, but those satellite sites were closed in the late 1980s, before the main site at Street. Dr. Martens shoes were also made in Somerset, by the Northampton-based R. Griggs Group, using redundant skilled shoemakers from C&J Clark; that work has also been transferred to Asia.
Document 10: Kobasicijada: Kobasicijada is an international sausage festival organized annually in the village of Turija, near Srbobran, Serbia. 32 festivals had been held as of February, 2017; it is one of the biggest and most popular village festivals in Serbia. The festival is attended by tens of thousands of people every year.
Document 11: Stillwater Mill: In September 2009, Breakwater Preservation Conservancy was given a donation of some 26 acres of property in Smithfield which included the remaining buildings of the Stillwater Worsted Mills. This was a very exciting acquisition for us as it is not only one of the most scenic locations in Rhode Island but it is also historically unique in that the whole concept of the mill community started on this very spot. During our investigation of T. Levy in 1909 and that the social innovations started there were far ahead of their time, are the creation of the Levy family. This and many other ideas originating at this mill can be argued to have been pivotal events leading towards success in both the first and second world war.
Document 12: Alcohol laws of Wisconsin: The 1983 Wisconsin Act 74, effective July 1, 1984, created a drinking age of 19. Meeting in special session at the call of the governor, the legislature enacted 1985 Wisconsin Act 337, which raised the drinking age to 21 and brought the state into compliance with the NMDA (National Minimum Drinking Age) on September 1, 1986.
Document 13: U.S. history of alcohol minimum purchase age by state: From 1976 to 1983, several states voluntarily raised their purchase ages to 19 (or, less commonly, 20 or 21), in part to combat drunk driving fatalities. In 1984, Congress passed the National Minimum Drinking Age Act, which required states to raise their ages for purchase and public possession to 21 by October 1986 or lose 10% of their federal highway funds. By mid-1988, all 50 states and the District of Columbia had raised their purchase ages to 21 (but not Puerto Rico, Guam, or the Virgin Islands, see Additional Notes below). South Dakota and Wyoming were the final two states to comply with the age 21 mandate. The current drinking age of 21 remains a point of contention among many Americans, because of it being higher than the age of majority (18 in most states) and higher than the drinking ages of most other countries. The National Minimum Drinking Age Act is also seen as a congressional sidestep of the tenth amendment. Although debates have not been highly publicized, a few states have proposed legislation to lower their drinking age, while Guam has raised its drinking age to 21 in July 2010.
Document 14: Alcohol laws of Wisconsin: The drinking age in Wisconsin is 21. Those under the legal drinking age may be served, possess, or consume alcohol if they are with a parent, legal guardian, or spouse who is of legal drinking age. Those age 18 - 20 may also be served, possess or consume alcohol if they are with a parent, legal guardian, or spouse who is of legal drinking age. Those age 18 to 20 may also possess (but not consume) alcohol as part of their employment.
Document 15: Alcohol laws of New York: In response to the National Minimum Drinking Age Act in 1984, which reduced by up to 10% the federal highway funding of any state which did not have a minimum purchasing age of 21, the New York Legislature raised the drinking age from 19 to 21, effective December 1, 1985. (The drinking age had been 18 for many years before the first raise on December 4th, 1982, to 19.) Persons under 21 are prohibited from purchasing alcohol or possessing alcohol with the intent to consume, unless the alcohol was given to that person by their parent or legal guardian. There is no law prohibiting where people under 21 may possess or consume alcohol that was given to them by their parents. Persons under 21 are prohibited from having a blood alcohol level of 0.02% or higher while driving.
