The propylene glycol / vegetable glycerin ratio strongly influences the vape experience.
- An e-liquid rich in propylene glycol or PG (70/30, 80/20) enhances the throat hit, flavour accuracy and a discreet vape. The e-liquid will be fluid and compatible only with MTL devices with a tight draw to avoid leaks.
- An e-liquid rich in vegetable glycerin or VG (30/70) produces more vapour and clouds, with a smoother, sweeter sensation. This thicker e-liquid will be compatible with sub-ohm or shisha-type e-cigarettes, producing large clouds of vapour at high power.
The choice therefore depends on the power and compatibility with your e-cigarette. If in doubt, the most common ratio remains the 50/50 PG/VG. Balanced, it allows versatile use on MTL, RDL and light DTL e-cigarette models (between approximately 15 and 40 watts).
