Which and why?
What brand, year? 
DIV
Casillero del Diablo, Cabernet Sauvignon, Chile, Any year
Don Melchor, Cabernet Sauvignon, Chile, Any year
First one is not expensive (like us$10 @ supermarket) and it's really a great wine, i dont know why is it so cheap when it could be easily sold at us$50, it's great while you are doing a real bbq
Second one is really really great, expensive though (us$100+) but oh damn, its one of those wines you will never forget. I think this one can be found in USA and EUROPE.
We have many in Chile, i'll recommend me you some more if you want, when i return to my country
