Our Story

Established in 2000 by winemakers David O'Leary and Nick Walker, O'Leary Walker Wines crafts exceptional small batch, vegan-friendly wine for you to enjoy today and for years to come.

With over 35 years of experience and established reputations making wine with some of Australia's most prestigious companies, long-time friends David and Nick decided to take control of their own destiny and produce small batches of carefully handcrafted 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 do.

2010 saw the opening of O'Leary Walker Winery and Cellar Door at Leasingham in the Clare Valley, South Australia, with a sister Cellar Door opening in 2015 at the historic Johnston Brewery site in Oakbank, Adelaide Hills. Each venue allows O’Leary Walker to showcase our regionally distinct wines, from our signature Watervale Riesling to cool climate Pinot noir. We look to celebrate the best of South Australia's grape-growing regions, making the conscious decision to draw on fruit varieties that excel in these varied viticultural climates.

O'Leary Walker Wines celebrates its 20th year in 2020, with an established reputation for producing award-winning regional wines which combine uncompromising quality with personality - and we can't wait for what the future holds.
