European Union wine regulations are common legislation related to wine existing within the European Union (EU), the member states of which account for almost two-thirds of the world's wine production.
 These regulations form a part of the Common Agricultural Policy (CAP) of EU, and regulate such things as the maximum vineyard surface allowed to individual EU member states, allowed winemaking practices and principles for wine classification and labelling.
 The wine regulations exist to regulate total production in order to combat overproduction of wine and to provide an underpinning to Protected designations of origin (PDOs), among other things.
 In a sense, the wine regulations therefore try to protect both the producer and the consumer.
European Union wine growing zones are used in the common European Union wine regulations to regulate certain aspects of winemaking.
 The zones differ in terms of climate and examples of what is regulated by wine growing zone are required grape maturity at harvest and allowed levels of chaptalisation.
 There are 21 wine producing countries in the European Union, with 14 of them having significant levels of production.
 In the 2004-2005 vintage, total European Union wine production was around 184 million hectoliters (4.8 billion gallons) which accounted for nearly 70% of total worldwide production.
 Of that total, nearly 55% was classified as table wine with 4% used in the production of grape-based distilled spirits such as Armagnac and Cognac.
Ketel (Dutch for: "Pot still") One is a liquor brand of the Nolet Distillery in Schiedam, the Netherlands.
 Ketel One Vodka is distilled from 100% wheat in copper pot stills, filtered over loose charcoal, and rests in tile lined tanks until ready.
 Ketel One Vodka is named after the original copper pot still, "Distilleerketel #1."
 The alcohol content of this spirit is 40% (80 proof (US), 70 degrees proof (international)).
 The Nolet Distillery also makes Ketel One Citroen, Ketel One Oranje, and Ketel 1 Jenever.
Jenever (] , ), also known as genièvre, genever, peket, or in the English-speaking world as Dutch gin or Hollands (archaic: Holland gin or Geneva gin), is the juniper-flavored national and traditional liquor of the Netherlands and Belgium, from which gin evolved.
 Traditional jenever is still very popular in the Netherlands, Belgium and nearby French and German regions.
 The European Union regulations specify that only liquor made in these two countries, two northern French departments and two German federal states can use the name "jenever/genever/genièvre".
European Union patent law is a subset of European patent law.
 It also serves as the superset of the patent laws of the individual member states of the European Union (EU).
 The most recent (proposed) addition to the range of measures currently in place is the Directive on criminal measures aimed at ensuring the enforcement of intellectual property rights.
 The most recent directive relating specifically to patents is Directive on the patentability of biotechnological inventions.
 Patents are probably the least harmonised area of intellectual property laws of the European Union insofar as harmonisation through EU Directives and Regulations is concerned.
 However, patentability criteria have been substantially harmonized by the European Patent Convention.
This List of DOP Italian cheeses includes all the Italian cheeses which have Denominazione di Origine Protetta ("Protected Designation of Origin"), or DOP, status under European Union regulations.
 All of the existing "DO" cheeses were registered by the EU as "DOP" cheeses during the course of 1996.
A defeat device is any motor vehicle hardware, software, or design that interferes with or disables emissions controls under real world driving conditions, even if the vehicle passes formal emissions testing.
 The term appears in the US Clean Air Act and European Union regulations, to describe anything that prevents an emissions control system from working, and applies as well to power plants or other air pollution sources, as to automobiles.

 The Finnish government-owned railways are regulated by specific laws.

European Union law is a system of rules operating within the member states of the European Union.
 Since the founding of the Coal and Steel Community after World War II, the EU has developed the aim to "promote peace, its values and the well-being of its peoples".
 The EU has political institutions, social and economic policies, which transcend nation-states for the purpose of cooperation and human development.
 According to its Court of Justice the EU represents "a new legal order of international law".
<ref name="Case 26/62">"Van Gend en Loos v Nederlandse Administratie der Belastingen" (1963) Case 26/62</ref> The EU's legal foundations are the Treaty on European Union and the Treaty on the Functioning of the European Union, unanimously agreed by the governments of 28 member states.
 New members may join, if they agree to play by the rules of the organisation, and old members may leave according to their "own constitutional requirements".
 People are entitled to participate through the Parliament, and their national governments in shaping the legislation the EU makes.
 The Commission has the initiative for legislation, the Council of the European Union represents member state governments, the Parliament is elected by European citizens, while the Court of Justice is meant to uphold the rule of law and human rights.
 As the Court of Justice has said, the EU is "not merely an economic union" but is intended to "ensure social progress and seek the constant improvement of the living and working conditions of their peoples".
European corporate law is a part of European Union law, which concerns the formation, operation and insolvency of corporations in the European Union.
 There is no substantive European company law as such, although a host of minimum standards are applicable to companies throughout the European Union.
 All member states continue to operate separate companies acts, which are amended from time to time to comply with EU Directives and Regulations.
 There is, however, also the option of businesses to incorporate as a "Societas Europaea" (SE), which allows a company to operate across all member states.
