Here are a few tester reviews from the INW site:
Very nice flavour, there’s gingerbread, cinnamon and everything in fine proportions, extra.
Best concentration: 18-20 drops/10 ml
Gingerbread taste with well recognizable spices, cinnamon and cloves are dominating.
Best concentration: 16 drops/10 ml
This flavour surprised me nicely. Apparently it reminds gingerbread spices or to hot beer (which I don’t like too much, if they are too many)while here they are very nicely composed. The ready LQ is sometimes delicately scorching, you can recognize ginger, cinnamon, cloves andeverything in the proportions I liked.
Bestconcentration: 20 drops
AWESOME– UNIQUE and DIFFERENT combination – throughout this testing Ifound out that I LOVE GINGER ! When inhaling you can feel the ginger (and maybe some cinnamon with a grapefruit touch??? and when exhaling there is something - maybe biscuit – making it smoother & leaving a nice sweetness on your lips … I LOVE IT !!! Best concentration: 4%
