I confess, last weekend I did pick up a bottle each of Chs. Loudenne, Lanessan, and Coufran, each at $20 or less, to see if there was anything interesting there. Back in the old days when I covered Bordeaux, I thought all three made decent or better wines. Will report on them when I've tasted. One of the reasons why I haven't bought any claret in many years is that I want an inexpensive wine (i.e., ~$20) that tastes like claret. I couldn't tell without tasting whether a wine was going to be faithful to my idea of what a claret should be or if it was going to be (to use a neutral term) new style, and the young clerks in the stores didn't understand what I was talking about because they'd never experienced traditional claret.
Another of the reasons why I lost interest in Bordeaux is that it became all about Merlot and I find Cabernet Sauvignon more interesting. Even in the Mdoc, the percentages of Merlot have greatly increased for most estates. (Now, I wonder who could be responsible for that?) Strangely, the only person I know who has made an issue of that change is Neal Rosenthal.
I think Larry dates my post on traditional estates as too recent, it was probably more like 5-8 years ago that I did it; I've lost complete touch with Bordeaux since then (2001 was my last trip to Bordeaux and I've done a few trade tastings since then, but I think 2004 was the last vintage for that).
