Confusing things in wine is common. There’s an old story about André Simon—I think it’s been attributed to other famous wine connoisseurs also—that he was once asked: when did you last confuse Burgundy and Bordeaux? He thought for a bit, scratched his head, and said, “Well, not since lunch, anyway.” But surely everyone can tell the difference between Cabernet Sauvignon and Cabernet Franc? Well maybe not.

I bumped into a curious situation when I was researching Cabernet Sauvignon on the right bank of Bordeaux for my book Claret & Cabs. There’s really not very much at noted châteaux because it’s so difficult to ripen. Merlot of course is the predominant variety, and if there’s Cabernet, it’s usually Cabernet Franc. On the graves of St. Emilion, Château Figeac is the standout example, with 33% each of Cabernet Sauvignon, Cabernet Franc, and Merlot, and there are also a couple of other châteaux with significant amounts. The area of the plateau where these châteaux are located extends into Pomerol, so I took a look there, and discovered to my surprise that Château Petit Village was reported to have 17% Cabernet Sauvignon. I had not realized anyone in Pomerol had that much.

Then I discovered that in 2010 the reported proportion of Cabernet Sauvignon at Petit Village had dropped to 7%. Ahah, I thought, they must have discovered that it doesn’t work well enough, and pulled it out, it would be interesting to discuss this. So I made an appointment to visit the château. When word of the visit reached AXA (who own Château Petit Village), it was cancelled. “We do have some Cabernet Sauvignon on the estate, however not much (less than 7%), and our main concern there is Merlot, the main grape variety on the estate. We do not feel that speaking about Cabernet Sauvignon here is relevant to the style and personality of the wines from Petit Village,” said Marie-Louise Schÿler of AXA.

This seemed a bit over-sensitive, but I then discovered that in fact there had never been that much Cabernet Sauvignon anyway. A review of current wines mentioned that a plot of old vines that had survived the frost of 1956, and which had been thought for fifty years to be Cabernet Sauvignon, had been discovered really to be Cabernet Franc. My efforts to discuss this with René Matignon from Château Pichon Baron (also owned by AXA), to whom the report about the discovery was attributed, were rebuffed. “I prefer you address your requests to Marie-Louise Schÿler,” he responded.

So I cannot report any details about the character of this Cabernet Franc, but I do think that a plot of Cabernet Franc that could masquerade as Cabernet Sauvignon for over half a century might have something rather interesting to contribute to the future of the right bank, especially given the difficulties created by the warming climate trend. Perhaps AXA will relent and allow me to taste some barrel samples in the future.
