PG vs VG: What They Mean in Your E-Liquid



If you’ve ever browsed e-liquids online or checked the label on a bottle, you’ve probably seen two mysterious ingredients: PG and VG. But what exactly are they, and why do they matter when it comes to your vaping experience?


Let’s break it down in simple terms.





What is PG (Propylene Glycol)?



PG (Propylene Glycol) is a thin, odorless liquid that carries flavour really well. It’s commonly used in food, cosmetics, and medicines, so it’s been widely tested for safety in everyday use.



Why PG matters in e-liquid:



  • Stronger flavour → PG delivers sharper, cleaner flavour profiles.
  • Throat hit → Higher PG levels mimic the sensation of smoking, which many ex-smokers prefer.
  • Thinner consistency → PG-heavy e-liquids work better in smaller devices and vape pens.






What is VG (Vegetable Glycerin)?



VG (Vegetable Glycerin) is a thicker, slightly sweet liquid derived from vegetable oils. It’s also commonly used in foods and personal care products.



Why VG matters in e-liquid:



  • Bigger clouds → High VG produces dense, smooth vapor (great for “cloud chasers”).
  • Smoother inhale → VG gives a gentler throat hit compared to PG.
  • Sweeter taste → It can add a natural sweetness that balances flavours.






The PG/VG Ratio Explained



Most e-liquids are a blend of PG and VG. The ratio affects flavour, throat hit, and cloud production.


  • 50/50 → Balanced flavour, medium throat hit, moderate clouds. Great for beginners.
  • High PG (e.g., 70/30 PG/VG) → More flavour, stronger throat hit, less vapor. Ideal for small pod systems.
  • High VG (e.g., 70/30 VG/PG) → Smoother inhale, bigger clouds, slightly muted flavour. Best for sub-ohm devices.






Which Blend Should You Choose?



It depends on your preferences and your device:


  • Prefer strong flavour & throat hit? Go for a higher PG blend.
  • Prefer smooth clouds & softer inhale? Choose high VG.
  • Not sure? Start with 50/50 — it’s versatile and works in most devices.






Final Thoughts



PG and VG might sound like complicated chemicals, but really, they’re just the building blocks of your e-liquid. Understanding the difference helps you choose the right balance for your taste, throat hit, and cloud style.


So next time you’re shopping for e-liquids, take a quick look at the PG/VG ratio — it’s the secret to finding your perfect vape.
