Steen,
I found this on another web site... Maybe it will help.
"In the truest sense some tobaccos are considered "aromatics" in their natural state, both Latakia and Perique, fall into this category. But as normally used aromatic refers to any blend which has had its aroma enhanced. The expensive way is by relying solely or primarily on the mixture of tobaccos to achieve this end, the easy way is take a tobacco and add other ingredients to get the end you want. These other ingredients can be as simple as honey or whiskey, to a whole slew of artificial flavourings.
The amount of non-tobacco ingredients is set by law and usage, according to Milton Sherman in "All About Tobacco" :
"It is estimated that less than half of one percent of the weight of any given brand manufactured in the United Kingdom is composed of flavorings, as contrasted with some brands manufactured in the United States in which casing sauces constitute as much as 25% of the gross weight of the tobacco product, or in the ease of Dutch tobaccos, as high as 35 %."
His book was written before the Germans entered the marketplace in a big way, so i have no idea what limits they have on their product.
But you will note that the Brits are never going to produce anything like some of the confectionary products of other countries.
What really matters is what you like. I still rotate some aromatics through my pipes, and tend to them in social situations, simply because non-smokers seem to find the much less offensive."
