See my earlier comments about the wines in this tasting from Australia's acknowledged King of Riesling.
Jeffrey Grosset Polish Hill Riesling 1992 17 Drink 2003-2006
Mid-gold. Very neat, low-key, fully mature nose, and still very vibrant on the palate. No desperate hurry to drink. Lots of mineral evolution. (12.50 per cent alcohol)
Jeffrey Grosset Polish Hill Riesling 1994 15.5 Drink now
No nose, except for a vague sherbet character. Minerals, and slightly hard and ferrous. Firm though. Pretty admirable for the age, despite relatively low acidity. (12.5 per cent)
Jeffrey Grosset Polish Hill Riesling 1995 16 Drink 2004-2007
Quite deep...
