I really loved this at a recent German 2009 QmP Riesling tasting: bright pale gold yellow; minerals, delicate white flowers on the nose. Sweet (but not cloying), ripe limes, sweet & sour pickled thai green mangoes on the palate. Excellent acidity and length. Rounded off the whole thing with good mouthfeel too.
