Here's my armchair guess at recreating the blend.
The component list according to tobacco reviews:
- St James perique
- Samson oriental
- Air cured dark burley
- Flue cured gold leaf VA
Most reviewers including
@jiminks are saying the burley is actually dark fired burley/kentucky rather than air cured burley. That would certainly change the flavor profile if true but would account for the intense pepper level (aside from the perique). Flue cured gold leaf is a bit vague, but flue cured blonde VA would probably be in the ball park.
As far as figuring out the ratios you'll need to do some dissection of the blend itself. Maybe pour out a half ounce on a table and start separating the ribbons by leaf type. That should give you an approximate ratio of each component.
The exact style of perique might be tricky. Standard St James might be all you need; however given the various types of perique that D&R have sold in the past there might be some variation there (Belmont, Grand Point, Paulina, S Vacherie)
I doubt there's any topping on the blend but likely some casing on the VA (sugar, maybe citrus). Any air cured burley would also have casing, but if it's truely dark fired then it wouldn't.
