Which perique blends are biting you? It could be it is not the perique in them, but the red virginia content. I have a body chemistry issue that does not allow me to smoke blends high in the reds as it is like acid to my tongue. I do smoke 5 Vaper blends that do not do this to me. They are the following.
Escudo
Dunhill Deluxe Navy Rolls
Solani 633
Samuel Gawith St James Flake
Dan tobaccco Treasures of Limerick
Vaper blends from Rattrays, McClellend, GL Pease,Former, Hearth and Home, C&D, Peter Stokkebeye have high red content so I have given up trying to smoke them.
