Correct dilution unlocks a concentrate’s designed profile. Wrong solvent choice or ratio creates cloudiness, off-notes and instability that no formula quality can rescue.
Key Highlights
- PG suits most flavor concentrates; ethanol for top-note lift; water only for water-soluble grades
- Standard e-liquid working range: 3-8% concentrate in PG/VG
- Add concentrate to base slowly with mixing; avoid shear heating
- Rest diluted blends 24-48h for full flavor development
Solvent Selection
| Solvent | Best For |
| Propylene glycol (PG) | Most concentrates, e-liquids, general dilution |
| Ethanol | Top-note lift, spray applications |
| Triethyl citrate | Oil-soluble systems |
| Water | Water-soluble grades only |
Using the wrong solvent causes haze or separation. If uncertain, request the TDS solubility data or run a 1:10 clarity test before batch scale-up.
Process and Rest
Add concentrate into the bulk solvent slowly under gentle mixing. High shear generates heat that volatilizes top-notes. After dilution, rest 24-48 hours – freshly diluted blends taste unbalanced until components fully integrate.
Frequently Asked Questions
Why does my diluted flavor taste different after a week?
Fresh dilutions integrate over 24-48 hours; premature evaluation misleads. If drift continues beyond a week, check solvent quality and storage temperature.
Can I dilute with water?
Only water-soluble grades. Otherwise haze or separation results – confirm solubility on the TDS first.
