I've been exploring many different tobaccos lately, and I've noticed that all of them taste as if they've been tainted with soy sauce (or something similar; it's a salty/metallic taste at the back/center of the tongue). It also lingers when I'm not smoking. I initially thought the taste was common to a blend I was trying, until I noticed the taste in everything I tried.
Is this indicative of tongue burn? Might this clear up even with more gentle, slower smoking?
