Question: Which Ketel One liquor is the only liquor that can use its name, according to European Union regulations?

 The Nolet Distillery also makes Ketel One Citroen, Ketel One Oranje, and Ketel 1 Jenever. 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)). <SEP> 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.  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".  Traditional jenever is still very popular in the Netherlands, Belgium and nearby French and German regions. <SEP> 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. <SEP> 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".
