Conceived as a white wine development program, the Bin 51 Riesling soon became one of Penfolds' star performers. Eden Valley is an obvious choice of region for Riesling due to the higher altitude and cool climate. The wine offers delicate aromas of fresh cut apples and pears with a twist of lemon and minerality towards the end. A great deal of fruits and acidity makes for an interesting white wine with propensity to age gracefully if carefully cellared.
