The 2015 Riesling Bin 51 has a restrained, youthful, citrus-laced nose offering suggestions of lemon peel and lime leaves with a waft of chalk dust. Dry, elegant and tight-knit, there is a very appealing zestiness to the palate though it is a little austere and closed at this youthful stage. Give it 2-3 years to open out and then drink it over the next decade.
