Penfolds Reserve Bin A has evolved into a recognizable single region style of its own, a distinctive and contemporary expression of Adelaide Hills Chardonnay. Grapes are all hand picked into small bins and whole bunch pressed. Juices are incrementally filled, directly from the press, into an extravagantly high proportion of new French oak barriques and treated to a natural wild yeast vinification. Every individual barrique creates its own unique 225 litre ferment. Enhanced mouth feel and luxurious complexities are achieved by fermenting on grape solids. All barrels complete full natural malolactic, followed by nine months maturation before bottling without filtration. Alcohol 13.0%
