There is definitely good wine and not so good wine, if you define "good" as something you like.
I could believe that there is a tenuous link between price and quality, but that's not the same as saying there is no good wine.

Did that to a couple of headstrong wine people, they were unable to tell their favorite (chardonnay for one and shiraz for another) from a bunch of AUD7 bottles.
Not sure if we could have told it from a $40 bottle, but it certainly stood head and shoulders above the $20 bottles we typically buy.
