They don't box any of their premium wines -- which is a shame. And they only sell their premium wines on the internet (disavow all knowledge of the box wines on the web site). I guess there is still stigma to the box, even in the enlightened markets. This is slowly changing. In NZ I came across a screw-top wine selling for USD 40 per bottle (putting it into the top 0.0001% price range for NZ wines, which are excellent but cheap). In the US it is hard to find any screw-top wines (in bottles, just no cork), and the few that exist are punished in the marketplace.
