Coonawarra's reputation rests on a single, narrow strip of terra rossa — red soil over limestone — barely more than a kilometre wide in places, running through South Australia's cool Limestone Coast region. That soil, combined with a maritime-moderated climate, has made it Australia's most celebrated source of Cabernet Sauvignon, producing wines with the region's signature mint and eucalyptus lift alongside blackcurrant fruit.

Key grapes: Cabernet Sauvignon, Shiraz, Merlot
