I started smoking a pipe a couple of months ago. I went to a shop near where I live and bought a relatively cheap pipe and a Mac Baren Scottish Blend. I really enjoyed the tobacco and when I had smoked throught it, I bought a new one. This pack tasted good for a while, but now it tastes really sour and isn't very enjoyable. I suspected it might have been the pipe, but I tried smoking it from a brand new one and it tasted all the same. Is it my fault, or does tobacco quality vary like that?
