Margaret River Sav Blanc is often as good as (if not better than) the NZ offering.

Particularly the Plantagenet Omrah lable. Mind you, in the absence of food I can't take more than one glass of this variety - it's just too much.

Massively over-rated would have to include:

- Penfolds Grange
- Penfolds RWT

Barossa Shiraz in general, really.
