If you are looking for top Australian riesling then the Clare and Eden valleys would be your first port of call, maybe followed by the Great Southern in Western Australia and Tasmania. Coonawarra would be a fair way down the list, but Wynns Coonawarra Estate has always produced a fine riesling and this is a very impressive offering from passionate young couple Steven and Emma Raidis, who are making some very good Coonawarra wines at reasonable prices. This is fresh and zesty, floral on the nose with stone fruit and citrus on the palate, varietal, and very food friendly, Chill it, pair with some pan-fried flathead fillets, and you will have a veritable feast on your hands. $20. www.raidis.com.au.
