Established in 2001 by David O'Leary and Nick Walker, their philosophy is pretty simple, source the best grapes from the best vineyard sites and craft great wine. O'Leary Walker is based at Leasingham in the Clare Valley, South Australia, but they don't limit themselves to producing just Clare Valley wines. O'Leary Walker also source fruit from other premium grape growing districts in South Australia including the Adelaide Hills, Barossa Valley, Coonawarra and McLaren Vale. The theory behind this is to draw on the grape varieties that excel in these quite different viticultural climates. OLeary Walker»
