Creating an intermediate vision with parameters really helped me through the bewildering choices. Safety first. Getting away from
analogs is supposed to be harm reduction, so flavors must not contain ...
- Diacetyl (zero tolerance)
- Acetyl Propionyl and Acetoin (as much as possible)
- sugars (mutates at high temperatures)
- Sucralose (mutates at 140F and higher temperatures)
Overtime, 'vapor tongue' or taste bud saturation will make any single juice boring or tasteless. Variety is key. I don't want to be swapping tanks (or coils/ wicks) for every distinct flavor, so I want a family of flavors that can transition from one to the other. As a coffee lover I want a set of flavors that involve coffee, custards, spices, liquors and various baked goods/ desserts that are sympathetic ... roughly a universe with around 20 flavors.
20 flavors will still results in 100s (if not 1000s of recipes), but at least combinations are not in the millions. You may want to try a family of fruit flavors and related ingredients. Hope this helps.
