Rothnh,
I don't want to keep beating this horse, but....
It is virtually NEVER the case that a pipe blend containing perique contains 100 percent perique from St. James parish. There is virtually no perique on the market right now for pipe smokers that is all from St. James or that is all "real" perique. No perique fitting that definition has been produced in quantity for pipe companies in several decades, and the thread you linked to actually contains a post from Kevin explaining this.
Virtually ALL of the perique used today by blenders comes in the form of perique blends (sometimes called "Acadian"). These Acadian blends contain a small portion of "authentic" perique mixed with some green river burley that's been processed in the same way. Unless you've actually been to St James Parish and bought some from one of the several farmers who produce it, then it is very very unlikely that you have ever smoked "real" perique. And it's pretty much a certainty that you (nor I, no anyone on this forum under the age of 50 or 60) has ever smoked a tobacco blend containing anything other than "Acadian" perique.
In fact, I have a hard time (as you can probably tell from my liberal use of scare quotes) describing the perique available now as anything other than the "real" thing. It's all most of us have ever smoked, it's what industry professionals mean when they use the word "perique," and it most certainly does contain some percentage of "real" perique.
Sorry to differ with you on this issue - I'm not wishing to be rude or argumentative, but I've seen this debate play out on numerous boards over the past few years and it concerns me that some newbie smokers might end up wasting time, energy or stress trying to track down some nonexistent "real" perique. Also, I'd hate to think of them missing out on some great blends because they don't want to waste their time on a "fake" or imitation product when, in fact, they are going to be unable to find any blends whatsoever that contain only "real" perique.
On that note, I'm going to crawl off my soapbox and fire up a bowl of Kajun Kake LOL.
Peaceable puffin',
Doc Thoss
