The wine law provisions applicable to all member states of the European Union are documented in EU regulations. The most important ones in terms of wine law are 1601/1991, 834/2007 (see also 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 that also concern wine law issues at least in part. For the layman, this is almost confusing, because amended regulations are promulgated by a separate regulation (with a new number). There is (unfortunately) no comprehensive body of EU law where you can find everything for a particular topic in one place. In addition, there are many country-specific laws and exceptions.
There is a vast number of sources on the web where one can acquire knowledge about wine. But none has the scope, timeliness and accuracy of the information in the encyclopaedia at wein.plus. I use it regularly and rely on it.Sigi Hiss
