K1 Wines

Under the custodianship of 5th and 6th generation descendants of Thomas Hardy, K1 Wines continues the family legacy of pushing the boundaries of Australian viticulture through innovation, a commitment to sustainability, and a love of the Australian terroir.
After joining his family’s wine business Thomas Hardy & Son in 1975, Geoff completed his diploma in wine production two years later in 1977.

In 1980, Geoff and fellow viticulturist Ian Leask purchased a vineyard in McLaren Vale. A few years later, Geoff found the perfect location for producing cool climate grapes in the Adelaide Hills. He planted the vineyard in 1987 and named it K1 since this unique site was the first commercial planting of vines in the Kuitpo region in the southern Adelaide Hills. Since then, Geoff has been involved in the planting of more than 3,000 hectares of vines and has consulted to more than 200 different vineyards in Australia, France and Italy.

In 2004, Geoff launched the Hand Crafted by Geoff Hardy and GMH ranges of wine, and then acquired the remaining share of Pertaringa in 2011. Since then, Pertaringa has been taken over by Geoff’s eldest daughter Bec Hardy and is now run entirely separately from K1.
