O. M. G.!!! What a flavor. I wonder how it'll change as it steeps...
Taste testing done on my MadVapes VV box mod mounting a Boge 2.5 ohm dripping atty. Listed voltages are 'unloaded' readings at the box.
At 3.7v you definitely get a 'dry' cocoa powder flavor on the inhale, with a 'creamier' chocolate finish.
At 4.0v the dryness fades away - still a cocoa taste. The exhale is more like hot chocolate.
At 4.5v the inhale tastes like an 80+% Swiss dark chocolate. The exhale is less hot chocolate and more like melted dark chocolate.
At 5.0v the 'good' flavors go away & we're headed into the burnt area.
5.5v? Don't bother.
Maybe this would change with a higher ohm atty.
