The Ambre is actually a bargain for what is in the bottle
This once again brings up the whole notion of QPR, Glenn. I agree with you: the Ferrand Ambre
is a bargain, considering what you're getting. And I think the Ferrand folks clearly understand the strategy of using the Ambre as a "gateway" for the rest of their superb cognac line, and price it accordingly.
When you consider that a VS grade cognac need have only 2 years of barrel aging, a VSOP only 4, and a Napoleon or XO only 6 (which highest grade will change, by the way, in 2011, but not that remarkably), and that the Ambre is a minimum 10 year old blend, the price for Ambre is remarkably good.
"Standard Cognac", a blend from all over with limited aging, versus Ferrand, all Grande Champagne Cognac with 10 years aging? No contest, in terms of taste and overall quality, I'd say. And for perhaps a few additional bucks per bottle, as you say, a true bargain. Thus an exemplar of QPR.
As to the remainder of the line, and older Cognacs in general: I can understand that it is difficult for many people to ever convince themselves to try those higher designations, simply because they are of necessity very expensive. And when investment in a single bottle is that high, for most people it's a stretch. So, absent a bar/restaurant that offers a glass at a slightly less painful single-serving price for the experience of tasting (and usually, the revelation that follows), most people simply don't have the luxury of exposure to the older Cognacs. Shame too. As you say, they are remarkable.
