The stuff you'll be served next might come from China, courtesy of Moet-Hennessy.
Seriously, I don't think it cane be much worse than some of the stuff (Chateau Ste. Michelle) that's served on some airlines. Drank some Chinese wines when KL had a promo a few years back and it was o.k., compared to cheap stuff from other parts of the world.
That said, I've never been impressed with Domaine Chandon stuff from California and Australia (Yarra Valley, Victoria). Haven't tried the Argentinean stuff and didn't even know they made the stuff in Brazil!
