I have samples of these in my hand right now

I love my tobacco shop, they are happy to have me as a pipe smoker so they drop samples on me all the time. I dont have much experience yet with pipe tobacco but I can say this, the black was very easy to smoke and stayed lit. I dont have a developed pallet so I can just tell you that my wife liked the room note and I liked the flavor but dont know how to describe it.
The Red was almost sweet to me and I can taste tobacco! This one is really good, it burned real cool and slow and didnt bite. Some of the stuff Ive been trying changes a lot from top to bottom of the bowl. Maybe it's the way I smoke but the Red stayed mellow and tasty way down into the bowl. I say sweet but there is to me bit of a spice to it as well. Almost like the "proper english" I tried was a spicey but more subtle.
Being new to the pipe I dont know if any of this helps but at least ya know someone likes it
