E-Liquids Explained

PG and VG are 2 of the major components that make up e-liquids and determine the size of your vape cloud. The e-liquid is absorbed into the cotton within the coil and as this heats up, it converts the PG and VG into a vapour combined with nicotine and flavours which is then inhaled by the user.

What is PG?

PG is also known as propylene glycol and is slightly thicker in consistency than water. It is a colourless and almost odourless liquid with a high boiling point which therefore requires the coil to reach a high temperature in order to produce vapour. The vapour density produced is very comparable to that produced by a cigarette. The role of PG is to carry the flavours and nicotine and to provide the best possible throat hit for your vaping experience. Therefore e-liquids containing high levels of PG will give a much more obvious throat hit making these the best choice for those wanting to replicate “as best as possible” the sensation of smoking. However, the higher the level of PG, the harsher the throat hit will be. As PG is almost tasteless, the flavours within the e-liquids really come to life.

What is VG?

VG is also known as vegetable glycerine and is a thicker consistency than PG. It is responsible for producing most of the vapour and adds a slight sweetness to the flavour of the e-liquid. The general rule of thumb is that the higher the level VG the bigger and denser the vapour cloud will be. This will also result in a slightly sweeter taste coming through. An e-liquid containing only PG would be too harsh on the throat so the VG helps to balance it out.

So how do I choose the best ratio?

This largely boils down to your personal preference of what you want to achieve in your vaping experience whether it be flavour, throat hit or cloud production:   

  1. Looking for bigger VAPOUR CLOUDS?
    Opt for an e-liquid containing higher levels of VG. The higher the VG level, the thicker the liquid and consequently the bigger the vapour cloud produced. Therefore, a ratio of of 30PG:70VG or 20PG:80VG works best if this is what you are wanting to achieve
    IMPORTANT NOTE: As these liquids are much thicker they aren’t suitable for use in all e-cigarettes but would instead work best in a sub-ohm device.
  2. Looking for the best FLAVOUR?
    If maximum flavour is your primary goal then 50PG/50VG would be your best choice. Alternatively, you could try an e-liquid containing 60PG/40PG however the throat hit will be a little harsher.
  3. Looking for a good THROAT HIT?
    As previously mentioned the higher the ratio of PG the more obvious the throat hit so the best options are 60PG/40VG or 70PG/30VG.
  4. Looking to be DISCREET? 
    To ensure you don’t compromise on flavour or vapour production your best choice would be an e-liquid containing an equal ratio of PG and VG (50PG/50VG)

What e-liquids work best with sub-ohm devices?

Sub-ohm devices usually work best with e-liquids with a high VG content (at least 60%) and containing no more than 6mg of nicotine. As more vapour is produced with sub-ohm vaping this would result in a bigger throat hit which would be too harsh with levels of nicotine above 6mg.
