The US is greatly behind the rest of the world for wine packaging. Here a "better" wine has to have a cork, and few wineries dare to go against this. Elsewhere lots of wine is package in plastic (either box or bottle) and even in paper bottles (like orange juice), so quite a bit past a screw top. I've seen wines costing USD 20 per liter packaged like this, and it works well. But it would never sell in the US.
