Apparently it is 30% Semois, and 70% 'blonde' lead. Vincent Manil has apparently been working on the blend for a decade or so. It is named after his son...
What makes Semois interesting to me is the provenance of the leaf. Since they won't tell us anything about the "blonde" component other than it adds a grassy note :roll: I'm not too interested.
I like both versions of Tobac-Manil Semois (thick cut and medium), so it's likely I'd like this as well. It sounds like some variant of Virginia, which should go well with the burley variant.
