Provisions valid for all member states are documented in EU regulations. The currently most important ones in terms of wine law are 1601/1991, 834/2007 (see also under EU Organic Regulation), 1234/2007, 479/2008, 555/2008, 436/2009, 605/2009, 606/2009, 1169/2011 and 1308/2013. In addition, there are about 20 other directives and regulations, which also at least partially concern wine law issues. For the layman this is almost confusing, as amended regulations are announced by a separate ordinance (with a new number). There is (unfortunately) no comprehensive body of EU legislation where you can find everything in one place for a specific topic. In addition, there are still many country-specific laws and exception regulations.
The standard work in Germany is the "Weinrecht" (Walhalla-Verlag, Wilhelm Schevardo and Josef Koy), which in the edition published in December 2019 comprises 4,570 pages plus CD-ROM. It offers the wine law of the EU, the Federal Republic of Germany and the Federal States. A further work is the online platform "Weinrecht" (Wine Law) published by the German Wine Institute(DWI) (digital successor to the "Weinrecht Kommentar" by Prof. Dr. Hans-Jörg Koch). The standard work in Austria is the "Wine Law" (Manz-Verlag, Hannes Mraz and Hans Valentin), which comprises 816 pages in the 5th edition published in 2018. It offers a comprehensive presentation of the entire wine law including all regulations and EU provisions. Furthermore, there is also the electronic database RIS (legal information system), which contains, among other things, wine law issues.
On the website of the European Commission there is the database "E-Bacchus". This database contains all the geographical indications(PGI) and designations of origin(PDO) of the member states (all wine-growing regions such as Chablis, Moselle or Wachau), the geographical indications and designations of origin protected within the EU by non-EU Member States on the basis of bilateral trade agreements on wine between the EU and non-EU Member States (e.g. trade agreements with the USA), as well as the traditional terms protected in the EU (e.g. Liebfrauenmilch or Gemischter Satz).
Almost all EU member states have applied for exceptions to many wine laws. The reasons for this are, apart from traditional customs, mainly climatic peculiarities. These are listed in the individual wine growing countries. Further information on wine law can be found primarily under Wine Law, where a list of other relevant keywords on the subject is included at the end.
