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.
