One of Australia's iconic Rieslings, the 2017 Polish Hill Riesling looks to be another terrific success. Youthful notes of petrichor and crushed stones surround a core of lemon and lime on the nose, while the medium-bodied palate is an impenetrably tight skein of wiry citrus flavors. Now and again, a glimpse of green apple or underripe peach pokes out, just to be reeled in and put in place by lime tendrils, which form almost endless curls on the finish.
