Context paragraphs:
Bigelow Tavern Historic District: The Bigelow Tavern Historic District is a historic district at 60, 64 and 65 Worcester Street in West Boylston, Massachusetts.  It consists of a cluster of three buildings: Bigelow Tavern, the White/Gibbs Store, and Temple's Distillery.  The buildings have a history of common ownership, and the area was locally important from the late 18th century into the late 19th century.  The district was added to the National Register of Historic Places in 1992.

Prussian education system: The Prussian education system refers to the system of education established in Prussia as a result of educational reforms in the late 18th and early 19th century, which has had widespread influence since.  It is predominantly used as an American political slogan in educational reform debates, since it was adopted by all American K–12 public schools and major universities as early as the late 18th century, and is often used as a derogatory term for education in the service of nation-building, teaching children and young adults blind obedience to authority, and reinforcing class and race prejudice.  The actual Prussian education system was introduced as a basic concept in the late 18th century and was significantly enhanced after Prussia's defeat in the early stages of the Napoleonic Wars.  The Prussian educational reforms inspired other countries and remains important as a biopower in the Foucaultian sense for nation-building.  Compulsory education on the Prussian example was soon mirrored in Scandinavia, and United States started to adopt the Prussian example.  Early American adopters include Daniel Coit Gilman, who set up The General Education Board, later renamed The Rockefeller Foundation, and first president of Johns Hopkins, John Dewey at the University of Chicago, James McKeen Cattell at The University of Pennsylvania and Columbia University, Henry Philip Tappan at The University of Michigan, James Earl Russell at the New York College for the Training of Teachers, and many more.  France and the UK failed to introduce similar systems until the 1880s.

Belle Isle Castle: Belle Isle Castle is a historic Irish landmark situated on Belle Island.  The estate stretches over 470-acres across Lisbellaw, County Fermanagh, Northern Ireland.  Built solely as a house in the early 17th century, Belle Isle Castle is now expanded and fully refurbished and serves as a popular tourist attraction, hotel and wedding venue.  It also contains on site cookery school.  Dating back to the early 17th century, the estate has been inhabited, owned and expanded by generations of nobles including Ralph Gore, 1st Earl of Ross.  The estate has welcomed the public since 1760 when it began hosting events.  In 1991, the castle was fully refurbished to open its doors to more visitors.  The castle contains a gallery, an overlook tower, a courtyard, and a grand banquet hall.  It also offers different residences throughout its coach houses and cottages, all of which include unique, different style bedrooms for its guests.  The estate encompasses English and Irish furnishings, a grand open fireplace, works by Russian, Irish and English painters, and floor-to-ceiling windows that overlook the garden, which has been manifesting since the 18th century.

Whiskey Rebellion: The Whiskey Rebellion (also known as the Whiskey Insurrection) was a tax protest in the United States beginning in 1791 during the presidency of George Washington.  The so-called "whiskey tax" was the first tax imposed on a domestic product by the newly formed federal government.  It became law in 1791, and was intended to generate revenue for the war debt incurred during the Revolutionary War.  The tax applied to all distilled spirits, but American whiskey was by far the country's most popular distilled beverage in the 18th century, so the excise became widely known as a "whiskey tax".  Farmers of the western frontier were accustomed to distilling their surplus rye, barley, wheat, corn, or fermented grain mixtures into whiskey.  These farmers resisted the tax.  In these regions, whiskey often served as a medium of exchange.  Many of the resisters were war veterans who believed that they were fighting for the principles of the American Revolution, in particular against taxation without local representation, while the federal government maintained that the taxes were the legal expression of Congressional taxation powers.

Welsh whisky: Welsh whisky (Welsh: "wisgi Cymreig" ) is a whisky made in Wales.  Whisky has been distilled in Wales since the Middle Ages, but production died out in the late 19th century.  In the 1990s attempts were made to revive the practice, resulting in the establishment of Wales's first distillery in over one hundred years.  Today Welsh whisky is represented by Penderyn.

Ephraim Davis House: The Ephraim Davis House is a historic First Period house on Merrimack Road, north of the junction with Amesbury Line Road in Haverhill, Massachusetts.  It is now an outbuilding of a farm, functioning as a garage and storage space.  The first part of the 2.5 story house was built in 1705 by Ephraim Davis, who married in that year.  This consisted of a central chimney and rooms to its right; rooms to the left of the chimney, and a leanto section in the back, were added later in the 18th century.  The house remained in the hands of Davis descendants into the late 19th century.  The house has been unoccupied since 1929, and has seen a variety of farm-related uses since then.  Its surviving First Period elements of note are its oak timber frame and central chimney, although it is possible the chimney is a later 18th century rebuilding.

Sion Hill (United States Virgin Islands): Sion Hill is a ruined sugar plantation and rum distillery on the island of Saint Croix, U.S. Virgin Islands.  Established in the 18th century, the estate passed through several owners while it was in operation.  The great house, the main residence on the plantation, is a one-story Classical Revival limestone building completed in 1765.  The factory and grinding mill, the two primary buildings used for sugar production, were also made of limestone; the distillery is located within the factory building.  The property also includes a cookhouse and a stable.

Bourbon whiskey: Bourbon whiskey is a type of American whiskey, a barrel-aged distilled spirit made primarily from corn.  The name is derived from the French Bourbon dynasty, although it is unclear precisely what inspired the whiskey's name (contenders include Bourbon County in Kentucky and Bourbon Street in New Orleans).  Bourbon has been distilled since the 18th century.  The use of the term "bourbon" for the whiskey has been traced to the 1820s, and the term began to be used consistently in Kentucky in the 1870s.  While bourbon may be made anywhere in the United States, it is strongly associated with the American South, and with Kentucky in particular.  As of 2014, the distillers' wholesale market revenue for bourbon sold within the U.S. is about $2.7 billion, and bourbon makes up about two-thirds of the $1.6 billion of U.S. exports of distilled spirits.

Watershed Distillery: Watershed Distillery is a microdistillery in Columbus, Ohio founded in 2010 by business partners Greg Lehman and Dave Rigo.  The distillery was the second distillery opened in Central Ohio after prohibition, and Watershed brought to market the first legally distilled bourbon whiskey in Central Ohio post-prohibition in 2012.  The distillery offers tours to the public and will also be the first distillery in Ohio to open a restaurant on-site in February 2017, following the passage of Ohio House Bill 351 in 2016.  The distillery offers six spirits, Vodka, two types of American style Gin, Bourbon, Nocino and a bottled Old Fashioned cocktail.

Rượu Phú Lộc: Rượu Phú Lộc is a spirit distilled from sticky rice fermented with a traditional strain of yeast.  Traditionally most of the villagers were engaged in the production of rice spirit, and pig breeding.  The residue of the distillation process was fed to the pigs and this often created the primary income of the villagers.  According to village historians distillation was introduced to the villagers by a Chinese woman probably around the 18th century.
