"he BEST wine producing countries focus on terroir, and name their wines for the region, not the grapes."
there's a greater difference between coonawarra cabernet sauvignon and a coonawarra merlot than a coonawarra merlot and a hunter valley merlot
hell every year tastes different!
the amount of variation within the terroir is also immense
i like wine made with cabernet sauvignon grapes picked in the right place at the right time aged >10 years more than any other sorts of wine, whether they come from south australia, bordeaux or california
but that's just me...
