"Primeur" and "nouveau"... wine or chemistry experiment?

With Beaujolais Nouveau 2010 lurking ominously around the corner, and after recently reading some blatantly one-sided pro-wine business propaganda telling everyone to go out and buy a new "primeur wine" (French websites / magazines Terre des Vins and Vitisphere, just to get myself threatened with legal action...); I thought it might be worth asking if anyone else has found some of these wines virtually undrinkable? Admittedly, some are nice enough, such as the 2010 Colombelle white I tried recently by Producteurs Plaimont in Gascony: in a mega aromatic boiled-sweet bubble-gummy estery zingy zesty crisp fruity kind of way (although, at €4 to €4.50 in France, not exactly a bargain). But most of these autumn "new wines" I've tasted over the years just taste like a winemaking / chemistry experiment and don't come together at all like, well, wine. Unless you left them for six months, so what's the point?! Well, great cash flow for the producer for a start... sold and banked before Christmas of the same year. OK, so maybe I'll buy one red and one rosé primeur/nouveau 2010 vintage to substantiate my rantings. Watch this space, if I can be bothered...
