Weyerbacher Brewing Company: Weyerbacher Brewing Company is a brewery in Easton, Pennsylvania, United States, founded in 1995 by Dan and Sue Weirback.  The brewery is well known for its "huge taste" beers.  Most of their brews are high in alcohol, with QUAD clocking in at 11.8% alcohol by volume, and a one-off 10th anniversary ale called Decadence brewed to 13% alcohol by volume.  Hops Infusion is one of the bitterest examples of the IPA style.  Weyerbacher is also a pioneer of aging beer in wooden barrels previously used for aging bourbon.  This process was used to transform Old Heathen imperial stout into Heresy, Blithering Idiot barley wine into Insanity, Merry Monks Belgian tripel into Prophecy, and QUAD Belgian quadrupel into Blasphemy.  These four styles are all very high-alcohol brews with complex flavor profiles; the barrel-aging lends additional oak and whiskey flavors.  The results have been widely praised by fans of huge beers, though persons accustomed to more mainstream beer may find them an acquired taste.

Office of the Director of Corporate Enforcement: The Office of the Director of Corporate Enforcement (ODCE) in Ireland was set up by the Irish Government on November 28, 2001 as a consequence of the proceedings and the conclusions of various review groups, courts, tribunals of inquiry and parliamentary committees in recent years.  These have revealed evidence that provisions in Irish company law and other legislation have been regularly breached and that some entities and individuals have not been called to account.  The result is that various parties, e.g., the State, other businesses and consumers, have borne the cost of this misbehaviour and the associated business risks.  Following a fundamental review, the Irish Government determined "inter-alia" that there were insufficient resources and legal instruments available to the State to supervise and enforce adherence to the requirements of company law and that it was necessary to correct these deficiencies in the public interest.

Beer in the Caribbean: The beers of the Caribbean are unique to each island in the region, although many are variants of the same style.  Each island generally brews its own unique pale lager, the occasional stout, and often a non-alcoholic malta beverage.  Contract-brewing of international beers is also common, with Heineken Pilsener and Guinness Foreign Extra Stout being the most popular.

Low-alcohol beer: Low-alcohol beer (also called light beer, non-alcoholic beer, small beer, small ale, or near-beer) is beer with low alcohol content or no alcohol, which aims to reproduce the taste of beer without the inebriating effects of standard alcoholic brews.  Most low-alcohol beers are lagers, but there are some low-alcohol ales.

Guinness Foreign Extra Stout: Guinness Foreign Extra Stout (FES) is a stout produced by the Guinness Brewery, an Irish brewing company owned by Diageo, a drinks multinational.  First brewed by Guinness in 1801, FES was designed for export, and is more heavily hopped than Guinness Draught and Extra Stout, and typically has a higher alcohol content (at around 7.5% ABV), which gives it a more bitter taste.  The extra hops were intended as a natural preservative for the long journeys the beer would take by ship.
