You might have guessed that traveling around the world to most of the wine regions requires a lot of planning and research! In order to pull together all our databases and articles, I research on-location by interviewing producers from the very vineyard. However I also do extensive research on with wine production information / statistics before traveling. In the hope that this might help with some of your own wine adventuring (or studying for your WSET Diploma or MW), here is a list of some of the resources I have found most useful so far: 
Global Resources
The International Organisation of Vine and Wine: useful statistics on global wine production
