Glad to see that you are finding your way through the considerable ammount of available tobaccos out there. I'm sure that you are getting to know a few blends very well. It is also very important to establish what you don't like, be it a genre or brand of tobacco. I am unable to tolerate Burley in any quantity as it is somewhat caustic to my mouth. I have learnt to avoid it as it can seriously spoil my enjoyment of this hobby. Its a shame as I like the taste but it doesn't like me. Good luck on your journey and enjoy what you like, not just what others recommend.
There certainly is an overwhelming amount of options to choose from in the pipe tobacco world, but I think I'm starting to get a good handle on what I like and don't like. My most enjoyed blends tend to be drier tobacco-forward aromatics like Cornell & Diehl and Mac Baren's aromatic offerings, but I still enjoy VaPers, VaBurs, and English blends now and then too.
As far as what I don't like goes, I just don't seem to have the right taste buds for non-aromatic Burley forward blends like Haunted Bookshop or Old Joe Krantz; they just taste like the way a barnyard smells to me.
The only tobaccos I've found that really don't work with my mouth chemistry are bright Virginias, which is a shame because I do enjoy the that bright grassy flavor, but they bite me like the devil everytime I smoke them. I've found that I can reduce the bite a fair bit my smoking them extra slowly in a long stemmed churchwarden or choosing a blend that has Burley or Cavendish mixed in with the bright Virginias to tone them down a little, but I'll still have a slightly sore tongue everytime after smoking them.
Thankfully there still hundreds of other blends to choose from that aren't bright Virginia focused, though I still need to get brave and plunk down the money for tins of Mac Baren HH Pure Virginia and Capstan Blue at some point just for the sake of trying them. I am making it a point to try all the really iconic blends in the hobby, so I'll have to give a couple pure Virginia flakes a go eventually.
