Better known for its red wines, Penfolds has turned out a lovely Bin 51 Riesling in 2007. An alluring nose of orange sherbet and petrol leads into a medium-weight wine that manages to be both broad and mouthcoating and yet long and racy on the finish. May not be a long-lived Riesling by Aussie standards, but it should still drink well over the next 7-10 years.
