Just what I said here:
It was a decent, if somewhat generic, pipe tobacco flavor. But, sadly, I wasn't able to taste any "whiskey" notes.

Even though I had mixed this at the high end of the recommended percentage; it was certainly not an in-yer-face flavor.
I am at a bit of a loss, as how to judge
any of the SM concentrates, because I have never used NETs before. I don't know if they are weaker, stronger, or what.
@FranC, the percentages you mixed at (compared to my higher percentages), are more in line with the few ratings and recommendations I have been able to find. I will be curious to see what you, and your husband think, once you have a chance to vape them.
I still have plenty of each; to let them continue to age. I will see what, if anything, time does for them.
Maybe just a drop, or two, of Acetyl Pyrazine (AP) to help bring out the "nuttiness" of the mix?
