Not really! I only had it as 8-10% or so blend partner in Montes "Purple Angel", a mostly Carmenere wine.
It's funny that "Petit" Syrah and Petit Verdot are actually among the boldest, most tannic and alcoholic wines.... :)http://winefolly.com/tutorial/the-spectrum-of-boldness-in-red-wines-chart/
It's a difficult grape to grow and like some others very susceptible to phylloxera, this is why it's gone down in popularity. I know no single French single varietal wine, it's always blended there.
I have quite some Australian wines here, but no Petit Verdot. Maybe after California an exploration of tannic wines, though I wonder how the Petit Verdot tastes. Isn't it overly tannic?!
