PG vs VG: E-Liquid Base Guide
What's the difference between PG and VG base liquids?
PG (Propylene Glycol) and VG (Vegetable Glycerin) are the two main base liquids used in e-liquids. Check out our complete guide to PG vs VG e-liquids for detailed information. Each has distinct characteristics:
PG Base:
- Thinner consistency
- Stronger throat hit
- Better flavour carrier
- Minimal vapour production
- Quick-wicking in coils
VG Base:
- Thicker consistency
- Smoother throat hit
- Dense vapour production
- Sweeter taste
- Slower-wicking in coils
What ratio of PG/VG should I choose for my device?
The ideal ratio depends on your device type. Learn more about 50/50 vape juice and high VG vape juice to make the best choice for your setup.
