I have a number of fluids that would be perfect if they were a little sweeter. Is there anything easily available that a non-chemist can add to fluid to sweeten it without diluting the taste/nic a lot?
There are two sweeteners generally used in e-liquid: sucralose and ethol maltol. In my experience, sucralose gives a clearer, purer sweet (best for fruit and drink flavors), while ethol maltol gives a richer, creamier sweet (best for bakery and dessert flavors). Don't use tobacco flavors so don't know which would work best for those. (BTW, ethol maltol will gunk up coils very quickly, IME.)
I've never tried buying OTC sweeteners, just ordered them from my DIY vendor, so can't speak to relative effectiveness or safety.
Hey - I have a stevia plant/shrub. I got it as a curiosity (kids like to nibble tiny bits of the leaves).
Packaged stevia I've tried has a "unique" taste
I use KAL (it's the best) brand pure liquid Stevia. It's a 100% natural product in a vegetable glycerin/water base and can be found in any vitamin/whole foods type store. I'd "start" with no more that 1 drop per 10ml as it is very sweet.
