Well, this may explain why aromatics are much more likely to result in tongue bite...
First, some people are simply much more sensitive to the additives, chemistry in aromatics. It's a chemistry thing - not much you can do about that. I've been enjoying pipes for quite a while and simply cannot smoke aromatics. Second, Aros are notoriously difficult to dry, having good bit of propylene glycol. That stuff simply will not dry well.
Now, you may try some of the lightly topped quality pipe tobaccos. Those are not soaked in PG and have little to moderate amount of casing or topping for the flavoring.
Personally, I stick to English, Scottish, Orientals,Virginias and Va-Pers. No flavored pipe tobaccos for me.
With most of these, Virginias excluded, the likelihood of getting any bite is small.
Best of luck.
