O'Leary Walker Wines was established in 2000 by winemakers David O'Leary and Nick Walker. With over twenty five years experience and established reputations making premium wine with the big companies, these two long time friends decided to take control of their own destiny and craft small batches of wine from some of the best vineyard sites in South Australia. With a great leap of faith they are now doing exactly what they set out to. In just ten years O'Leary Walker Wines has become a critic success with James Halliday, one of Australia's most influential critics awarding the winery a coveted 5 star rating.The wines are regionally distinct with fruit sourced from other premium grape growing districts in South Australia including the Adelaide Hills, Clare Valley and McLaren Vale. Their theory is to draw on the grape varieties that excel in these different climates. O'Leary Walker celebrated its tenth year in 2010 with an established reputation for producing award winning regional wines at affordable prices.
