(BusinessWeek) - Hardys became Britain’s best-selling Australian wine brand by selling for as little as £3.40 ($5) a bottle despite the 37 percent surge in its home country’s currency since 2009. To do that and still earn a profit, the winemaker turned to plastic bags. No, not those bag-in-a-box jobs found at your local Sam’s Club (WMT) or Costco (COST). We’re talking 24,000-liter plastic bags, each able to carry the equivalent of 32,000 bottles of vino. Accolade Wines, the maker of Hardys, pared shipping costs that can amount to as much as $3 a case by ditching glass bottles and shipping its fruit of the vine in giant plastic bladders. After the 10,000-mile journey, the wine is bottled at a plant next to a scrap merchant a two-hour drive from London.
