I smoke plenty of Perique heavy blends. I'm currently going through a tin of The Beast, love Telegraph Hill and Haunted Bookshop, Exclusive....Acadian Perique.
At first I thought it was only the Perique. But at only 25% Perique, there is more to my dislike than that. I have smoked their granulated Perique straight and Green River Perique.....there is some way the tobaccos in Bayou Morning react to me. Very odd chemical reaction I'd suppose. Same as some pipers get tongue bite, and others don't.
I don't feel tongue bite, infact MacBaren VA#1 is one of my all time favorites. It's probably the #1 tongue scorcher in the tobacco world.
