I think the most important and traditional prodeucer, the mirror for the rest, is only one: FRANCE
The rest of the world has many good things also, and it's funny who countries specialises in varieties:
Australia: They changed Syrah for Shiraz
Argentina: Very strong in Malbec
Chile: Cabernet Souvignon and of course Carmenere, the only country that produced it.
As for the new markets, Australia is still the leader. but we have to look after South America. Chile is the far leader of the region, but Argentina is becoming more and more important.
Anyway, for tradition, good wines and branding,
Chile wins in South America,
France in Europe,
California in North America,
South Africa in Africa and
Australia in Asia/Oceania.
Of course my vote goes for Chile, great producer for all varieties, Red and White.
