Consider the moisture level of the tobacco. I'm also a beginner, and several kind people here pointed me toward drying tobacco or considering other blends that might work well with my pipe. Packing and tamping were definitely techniques that needed refining, lighter tamping that only just touches the ash, and packing for consistent airflow all the way through pipe and bowl.
But about the blends: my first tobacco was Captain Black (white package). The standard American aromatic with plenty of casing and shelf-life-extending preservatives ("goop", as it is often called on these forums). The result I was getting is that in my rather short pipe, it would either burn hot, giving me that spice-like tongue bite, or it would go out. I ended up puffing hard enough to keep it lit, which would make it hot, and create a cycle of negative effort there.
I was able to calm down the Capt Black a bit by drying it before a smoke. That helped it stay lit longer, but it still wasn't ideal for me and my pipe. After that I tried out another blend with less "goop" in it, Lane Limited: Burley Mild (
reviews here).
The result was it burned slowly and evenly, and it helped me understand how much of a factor the tobacco blend itself plays in the burning. It's the fuel and the flavor.
After having this comparatively positive, relaxing experience, I was able to return to the Capt Black with greater understanding and get a better smoke out of it, too.
Hope this anecdote helps. Cheers!
