I'm going to recommend my everyday favorite, Dunhill Early Morming Pipe. It's available in bulk, affordable and very tasty. You'll see opinions that are all over the map on this and others but I'd say ignore them, form your own. I recommend this blend because it is easy to enjoy if smoked properly and by that I mean slow. Once your pipe is lit and going good, just sip. This advice applies to ALL pipe tobacco btw. There's just a hint of Latakia present and some say there really isn't any but I can get just a hint.
This blend will allow you to learn how to get to know a pipe tobacco because of it's very subtle complexity, there's a lot going on with it if you take your time and really get to know it.
From here your possibilities are endless, I smoke a plethora of different blends weekly but I start each day with my beloved EMP.
Enjoy!
