It's fairly full in the mouth, with drying tannins on the finish; the flavor's very hard to describe, so all I'll say is that (surprise) it's no wonder that this grape seldom is vinified and bottled all by itself. It's not that it's unpleasant; it's just that it feels somehow incomplete on its won. There's kind of medicinal, almost horehound fruitiness, but other than that? I have to admit that I don't get it.

After I wrote this post, I spent a few hours with this wine... and grew to appreciate it much more. It may not be the most forgiving or enjoyable wine, but at least it seemed to be very much of itself. I suspect that the winemaker did a very good job indeed at allowing the grape to express itself; the naturalness and honesty of the wine was very impressive.
I gotta say, your writeup makes this wine sound really interesting, as much for its difference as anything else. Especially the velour couch bit. I love wines that sneak up on you over the course of an evening.
There aren't many wineries in Australia doing a straight Petit Verdot. Pirramirra in the McLaren Vale is a notable exception. Must try some more.
