NZHerald.com provides great coverage for WineSkin in April 2009:
Taking fine New Zealand wine overseas, to share with family or friends, is a bit fraught these days. The security rules on liquids mean you can no longer carry a couple of bottles in your hand luggage (unless you buy it in duty free where it’s usually expensive and the choice limited). But pack it in your check-in luggage and you travel in fear of arriving to find your clothes stained a tasteful red colour.
Happily, there is an alternative in the form of the US-invented Wineskin.
