O'Leary Walker is the culmination of two like minded winemakers. David O'Leary worked for Heemskerk and Chateau Reynella, he was group red winemaker for Hardy's and later at Mildara Blass. He held senior winemaking roles at Quelltaller where he launched Annies Lane. Nick Walker took up residence at Krondorf for sixteen years and was also at Yellowglen and Yarra Ridge. Cabernet grapes are destemmed but not crushed, into two and four tonnes fermenters. Natural yeasts are added as the ferments are hand plunged and pumped over to control temperature and flavour. Upon completion, batches are macerated, pressed and run into small French oak hogsheads for two years maturation.
