They like to call Australia "Oz," and for me, it's a fitting title because traveling its wine regions is like following the yellow brick road. Here, we'll visit three regions and profile three awesome wineries. First, we tour the Hunter Valley, Australia's first wine area, and one of its first wineries, Lindemans. Next, it's down to South Australia's Barossa Valley for the wines of Penfolds. Makers of Australia's most famous wine, Grange, Penfolds' portfolio is broader, and better, than ever. Last, but certainly not least, is the Coonawarra and Wynns. Known for classic Cabernet Sauvignons and Shiraz, winemaker sue Hodder had quite the deft touch with Chardonnay as well. We'll taste all three and end the day with an Aussie-style barbie right in the historic Wynns' cellars.
