The total production of Yattarna is just 500-1000 cases, one-tenth that of Grange. A warm, low-cropping, intense and less than outstanding year in the Adelaide Hills shifted the focus of sourcing to the Coal and Derwent Valleys of Tasmania, which account for 90% of the blend. The result is a powerful Yattarna, a vintage of heightened presence, concentration and acid structure, yielding a chardonnay of grand cru proportions, enveloping 62% new French oak, toned with scintillating, crystalline acidity. Grapefruit and white peach and fig abound, underlined by a lemon zest acid line and supported by creamy French oak. Heightened texture, concentration and acid presence rise in unison, to compelling effect, lingering on a very long finish. 15 October 2015 release.
