2020 Grosset, Polish Hill Riesling, Clare Valley, Australia

Riesling's twin peaks are its intense perfume and its piercing crisp acidity which it manages to retain even at high ripeness levels.

If ever there was a list of Australian terroirs, Clare Valley would be near the top. Its location an hour north of Adelaide, its latitude and heat degree days (over the growing season) suggest a very hot clime suited to reds, yet white wines prevail. Taut, lime-sherbet Rieslings with fine minerality and ageing capacity are the region's most famous product, followed by Shiraz and Cabernet Sauvignon.

Jeffrey Grosset, an oenology graduate, gained extensive experience with major Australian wine companies like Lindemans before establishing his winery 21 years ago in Auburn, Clare Valley.
