PipesMagazine.com: Now, tell us about Perique as far as being used in blending and in smoking, because I’ve heard that you don’t normally smoke Perique by itself. I’ve heard that it’s used more like a condiment for using with other tobaccos and blending. Is that correct?
Ryan: That’s right. Perique is used as a blending ingredient, like Latakia. It’s got a lot of character, a lot of richness, and it adds a lot to a blend, but too much can dominate to an extent that you don’t want that in there, just like with the Latakia. Some folks want straight Perique, but it’s not something the average person’s going to want, so it’s usually used in a blend, most commonly with Virginia. It’s a natural blend with Virginia. They compliment one another well. It makes the Virginia more smokable, cuts back on some of that cottony dryness you get in the back of your throat from Virginia, and it’s so much flavor. The flavors that you get out of the Perique are unbelievable. I mean, you’ve got that fermentation sort of fruity component, you’ve got an olive component, you got like a fine nut component, you got layer and layer of flavor from Perique. And we have both types. The one that most folks get is the blend, which is called Acadian Perique, and then the Straight St. James, which doesn’t sell as much, and we have that also.
PipesMagazine.com: The Straight St. James, that’s the 100%?
Ryan: That’s 100% St. James. What the guys discovered in the first half of the last century was that if you have a bad season, you lose 100% of the Perique and there’s none for anybody. And then the manufacturers phase it out.
So yes Acadian is St James perique it has just been cut with green river burley its not 100% st james.
Seems to me like blended malt whiskey vs single malt whiskey but thats just my take on it.
