Produced only in special vintages, Yarra Yerings Blanc de Blancs is a rare and (as you would expect) and utterly delicious wine. Made from estate-grown Chardonnay, it spends 7 years on lees, gaining depth and creaminess. The 2017 shows lemon zest, nougat and chalk, with pinpoint bubbles and length. Its a restrained, ageworthy and complex sparkling and a must try for lovers of this winery.
