This is an Aussie classic--big, bold and gregarious. Shiraz/Cab really holds no similarity to either Shiraz or Cabernet. It is a genre of its own, in the tradition of Penfold's Bin 389 and Koonunga Hill Claret. Strident Europhiles are bound to be horrified by the style (or lack of it). But if you can free yourself of your biases, you'll find a lot to like.
Talk about color--this wine is virtually opaque. Aromas are also full of big tannins but not big enough to shoulder away the ripe fruit. As in Bin 389, the Shiraz/Cab comes across with unique smells and flavors of dark chocolate, ripe berries, currants and leather. Malbec, not part of the traditional blend, adds a nice touch to the finish--sweet cherries and blue plums, lush and velvety.
This wine was brought to my house by a dinner guest; I believe it sells for $12 to $15. At the low end of that price, I'm a buyer.
