I get mostly a honeyish kinda taste with BB as well as tobacco. My girlfriend says it tastes like this rolling tobacco I used to like, it was called halfzware shag I think, and I kinda get that too though it's been quite a few years since I've had that stuff.
I tried it the first day I got it and didn't really like it at all, it was very harsh at 12mg in a dripper and even more so in my Kayfun. I'm vaping some right now in my dripper again and the harshness has gone down quite a bit and it has become quite enjoyable, I'm starting to see what all the fuss is about. The taste is pretty much the same as on the first day, though maybe a little sweeter, but without the harshness I was getting before. I definitely recommend at least a week's steep although it'll probably get better with a little more time, only time will tell for me.
I definitely prefer GJ so far, right out of the mail it wasn't hardly as harsh though I didn't get any banana flavor right away. I was vaping some earlier today, two weeks about since I received it, and the banana flavor has become much more pronounced.
