I am using a 100% VG base. The only PG comes from some PG based flavors that I use.
The only flavors I have issues with are the fruitier flavors. I can't get that "pop" that purchased juices have. I have recently tried adding a drop or two of liquid Stevia to them. (I have a few flavors split into two bottles, one with, and one without Stevia for comparison when they are done steeping) Even now though, they simply don't smell as sweet as purchased juices do.
Could the issue be the VG percentage? I have heard that dilluting with distilled water will bring flavors out more. I don't want to use much PG at all because it tends to irritate my throat.
Any and all help is appreciated!!!
