Australia\u2019s reputation may ride on Shiraz\u2019s back, but the trophy case for Cabernet Sauvignon is just as packed. It\u2019s one of the country\u2019s most planted varieties, grown from some of the world\u2019s oldest producing vines. This powerful, ageworthy grape thrives in maritime-influenced, dry, moderate climates and it seems to soak up Australia\u2019s various unique terroirs.\r\n\r\nWhile it\u2019s made throughout the country, three regions fly the Cab flag highest.\r\n\r\nThe red terra rossa soils of Coonawarra, on the southeast edge of South Australia\u2019s border, between Adelaide and Melbourne, produce some of the country\u2019s richest Cabs, with sturdy tannins, plush dark berry fruit, mint and dried herbs.\r\n\r\nOfferings from Margaret River, in Western Australia, straddle a line between elegance and power. Their ultrafine tannins and complex, savory aromas evoke the nearby Indian Ocean and towering gum trees.\r\n\r\nAround 30 miles northeast of Melbourne, the relatively cool climes of the Yarra Valley produce Australia\u2019s most delicate Cabs. These offer medium body, with fresh fruit-and-floral expressions that are balanced by chalky tannins.\r\n\r\nAustralian Cabernet may be blended, sometimes with Shiraz or with other Bordeaux varieties like Merlot, Malbec and Petit Verdot.\r\n\r\nTry Cab by itself or blended, from all across Oz, ideally with a plate of protein at hand.\r\nAustralian Cabernet Sauvignons to look for\u00a0\r\nCh\u00e2teau Tanunda 2016 Matthews Road Cabernet Sauvignon (Barossa); $18, 92 points.
