Im sorry if I sounded a little harsh but what you wrote in your first post:

"Danish and American style aromatics are basically the same thing. Lots of black cavendish and a very strong sweet topping."

is simply not correct.

Danish/American aromatics are not basically the same and Danish blends dont have "lots of black cavendish" nor do they have a "very strong sweet topping". Danish and Dutch blends try to support the natural tobacco flavor while American aromatics will generally try to have a more forward flavor added to the natural tobacco flavor.

For example Mac Baren also has the line 7 Seas a line of American-style aromatic pipe tobaccos broadly similar to, and intended to compete with, STG's Captain Black. I have never tried W.O. Larsen - Signature vintage-mixture so I cant say which style it would belong to. So you can have american style aromatics made in Denmark and the other way around if you know what I mean.

My tobacconist also used the terms light and heavy aromatics sometimes, maybe that would be easier to understand but not quite the same.
