Understanding E-liquid, PG and VG ratios.

All e-liquids have 4 fundamental components to it, no matter the brand or price. These 4 components are the amount of PG, the amount of VG, the amount of nicotine (if any) and the flavourings used.

This is mostly the same across all brands of e-liquid, the only thing that changes are the amounts of each component added and the quality of those components.

In this blog post I shall be focusing on PG, VG and the standard mix ratios you will come across.

PG or Propylene Glycol is found in the food industry mostly used as a preservative or in the medical industry in asthma inhalers. In terms of what it does for your e-liquid is it carries the flavour of the juice and is the thinner component of the e-liquid.

VG or Vegetable Glycerine is found in the food industry as a sweetener or a thickener.  In terms of your e-liquid it is a lot thicker of a liquid and helps to provide the denser clouds and a smoother vaping experience.

Here are a few standard mixes that you will typically find:
  • 50VG/50PG:
  • This PG/VG mix ratio is perfect for MTL kits and vaping at lower wattages with a higher nicotine content.
  • 70VG/30PG:
  • This mix ratio is the most common ratio found in shortfills.  Due to the e-liquid being a lot thicker this ratio suits sub-ohm kits and high wattages much better, while still providing a lot of flavour.
  • 80VG/20PG or "Max VG":
  • These ratios are normally used in competitive vaping competitions due to VG content being higher, bigger clouds can be made. This ratio is also best for people with a PG intolerance or people who want the smoothest vaping experience while sub-ohming.

I hope that has helped and if you have any questions please come in store and ask or message us on social media.
