The evolution of Penfolds Yattarna Chardonnay is the result of Australia's most comprehensive white wine development program. Inspired by the aspirations of the late free-thinking Max Schubert, Penfolds embarked on a project to create a flagship white wine. Starting in 1992 and spanning six vintages, John Duval and his winemaking team carefully developed more than one hundred trial wines. These were narrowed down to eight finished blends. The wines were painstakingly refined and assessed in order to reach a style and standard Penfolds felt would represent their best possible endeavor in winemaking. The appropriately named result of that project is Yattarna, which is Aboriginal for 'little by little' or 'gradually'.
