Well, that's like saying champagne only truly comes from a small area in France. Maybe C&D only uses pure Poche, but I'm skeptical.
That was an interesting article. What caught my eye was the varieties of leaf used in the varieties of perique-processed products including Virginia and dark fired burley. Recently Watch City Cigar offered a blend of tobacco containing oriental leaf processed as traditional perique.
Anyway, the style, feedstock or mixture of periques used by C&D in the early 2000s (even if it originated in Louisiana) was of a more peppery, rather than fruity variety. I tolerate and enjoy the fruity and not the peppery.
I found another article on periques: A Closer Look at Perique | Smokingpipes.com
