Coonawarra GI
Australia’s reference Cabernet Sauvignon GI. The terra rossa (red clay over limestone) soil produces distinctively minty-eucalyptus Cabernets.
About Coonawarra
Coonawarra GI is Australia’s most editorially significant Cabernet Sauvignon region — a narrow strip of terra rossa (red clay over limestone) soil near the Victoria border, southeast of Adelaide. The terroir is genuinely distinctive: the red-soil-over-limestone combination produces Cabernet Sauvignon with a unique minty-eucalyptus character (often called “gum leaf” in Australian wine writing) that distinguishes Coonawarra Cabernet from any other Australian zone. The cool maritime climate produces wines with relatively elegant tannin structure compared to Barossa or McLaren Vale Shiraz — less power, more finesse. Foundational producers include Wynns Coonawarra Estate (the historic reference producer, owned by Treasury Wine Estates), Penfolds Bin 707 Cabernet (sourced partly from Coonawarra), Lindemans St George, Katnook Estate, and the smaller Penley Estate, Balnaves, and Bowen Estate. The Coonawarra boundary dispute (in the early 2000s, smaller producers fought to exclude marginal land at the edges) created the formal GI boundaries.

Editorial notes
Coonawarra Cabernet ages 12-20 years from serious producers. The minty-eucalyptus character is the most distinctive Coonawarra terroir signal; some critics consider it a defect and some consider it the region’s signature.
