It was easy way back when, Jancis Robinson commented while she was studying for her master of wine, because there so were few wine-producing countries and wine-producing regions. Today, it is almost impossible to keep up.
Even those residents in Portugal's bourgeoning Douro region say they don't always know what's happening, such is the pace of change.
Places such as Italy's northerly Alto Adige and the volcanic island of Sicily are traditional regions but are arriving gloriously and belatedly on the world scene.
Bruno Prats, former owner of Cos d'Estournel, was the first to plant grapes in Chile's Malleco region, which is south even of another 'new' region, Bio Bio, pushing the frontiers of wine production still further.
Les Vins de Vienne were the first to rediscover a part of the Rh?ne known as Seyssuel (Chapoutier and others have subsequently planted there, too), which will probably become France's newest Appellation d'Origine Contr?lee within the next few years.
The British are storming ahead with their sparklings from the south of England, taking advantage of climate change to become a respectable producer, while southern Germany is finding the quality of its pinot noirs (Spatburgunder) soaring for the same reason.
It is probably fair to say that the point where price-quality ratio is at its most favourable is when we buy from up-and-coming, offbeat regions, often selecting their 'unique' grape - malbec from Argentina would be a good example.
