So now that we have this awesome device with variable voltage and the knowledge that different juices and their intended flavor's are best realized at a specific voltage, what's your process for finding what voltage works best? Do you just try one voltage at a time? Can you tell a difference between 3.7 and 3.8 volts? I see juice bottle labels of the future noting "Best flavor at X.X volts." I imagine much of it has to do with how viscous the juice is; PV to VG ratio. Thoughts...?
