So i got this in the post and it was a homer simpson moment, mmmmmm beer.
Put a new dct cartomizer in, primed it and filled her up with 1ml nicotine pg based, 1ml pg diluent, 1ml beer concentrate.
Wow it was good, but not what i expected. At first it was the nice taste of a proper beer, then bang the next taste, not what i was expecting. This taste i could not put my finger on, then it came to me, whiskey fudge

Totally was not expecting that, but was very pleasant.
