Knappstein 2006 Riesling (Clare Valley) – The prevailing “wisdom” that Australia = goop is relentlessly questioned by Clare Valley rieslings, which (if anything) bite, slash, and rend far more than their Germanic brethren. To the extent that they have acid balance issues, it’s almost always too much (or too aggressive), rather than too little, acidity. Here, too, the acid is almost lurid in its intensity, and while there’s a pretty solid layer of greenish-yellow fruit and apple skin pressing down upon it, this really is all about the vibrant spike of sharpness driving right through the wine’s center.
