Australia’s most expensive wine — a recently released Shiraz with a perfect score from an influential wine publication — costs a hefty 700 Australian dollars to 800 Australian dollars (US$700 to US$800) a bottle. But nobody seems deterred by it. All 400 cases of the wine, called the Laird, have sold. The 2005 vintage of the Laird is made by Torbreck, a boutique winery in the Barossa Valley region of South Australia, Australia’s most famous wine district. Since its release in September, it has won rave reviews from around the world, including a perfect score of 100 from the U.S. publication ”Wine Advocate.”
