Capella called Chocolate Caramel Nut
From what I have read this flavor received mix reviews, most in not so good to fair category (avg: 2.3 stars out of 5 stars).
I have not tried it because nothing much is written about it, which kind of tell us something.
Good chocolate read:
Chocolate... I gotta ask this question...
The TFA brownie taste is just poor (gawdawful nasty by itself) --yes.
This might help if your dying to find a half way descent chocolate vape, could try CA Chocolate Coconut Almond. I have a recipe I've worked on with toasted almond and butter added to the CCA and its tasting decent to bordering on good taste. The problem with this CCA flavor mix is that the chocolate is weak (strength) at 5-8%. Not much difference between the 5-8% increase.
I have a few other chocolate solutions I'm working on from medium cost flavor blenders (TFA,CA,FA etc.) to try to get in the good to near great chocolate taste category. If this does not work I will forget the search for an intense dedicated chocolate taste vape and be happy with the CCA mix.
There are other premium approx. $1-2 /ml. flavor/blenders available but a little too pricey for my piece of mind. I suspect the e-liquid/juice suppliers/blenders are paying these prices and selling their chocolate mixes to folks because the initial outlay cost, high though it is, is profitable. I just can't afford/justify to experiment in that price range.
