I have a love/hate relationship with Sauvignon Blanc (and blends) from France. On average I really enjoy the grape, but to get the intensity and complexity I generally prefer out of French wines it almost always feels like you have to start out at $40/bottle (if not more) to get to a quality point that other locales can provide for half the price.
This is not exclusive to Sauvignon Blanc. In all honesty, it is simply France knowing how to get the most for their wines abroad. But that being said, it seems especially true with all the Sauvignon Blancs we've tried.
The Sauvignon Blanc and Semillon blend from Chateau Picque Caillou from Pessac-Leognan was not much different. While this one was much more complex for its price point than we originally expected, we also weren't quite sure about the sell price in the USA.
