What’s The Difference Between PG & VG?

PG (Propylene Glycol) and VG (Vegetable Glycerin) are 2 of the major components that make up e-liquids and determine the size of your vape cloud. Both ingredients are considered very safe and non toxic and frequently used in food, makeup and medications. 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.

The amount of PG and VG in an e-liquid determines the amount of vapour produced, intensity of flavour, throat hit and smoothness of your vaping experience.  

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 of 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.

What is the best VG/PG Ratio?

There is no perfect ratio that suits everyone as ultimately it boils down to what you want to achieve from your vaping experience. The amount of PG and VG in an e-liquid determines the amount of vapour produced, intensity of flavour, throat hit and smoothness of your vaping experience so once you have decided what you are looking for you can then decide which e-liquid is right for you.

  • Flavour - 50/50 blends and e-liquids containing higher levels of PG (around 40PVG/60PG) will offer maximum flavour. However, it's important to remember that higher PG will also result in a stronger throat hit.
  • Throat Hit - E-liquids containing higher levels of PG will result in a more intense throat hit so best to choose 30VG/70PG and 40VG/60PG vape juices.
  • Large Clouds of Vapour - E-liquids containing high levels of VG will result in increased vapour as the thicker liquid is able to produce bigger and denser clouds. Due to the thickness of this vape juice, it must be used with a suitable device that has sub-ohm vaping capabilities. Best options are 70VG/30PG or 80VG/20PG e-liquids.
  • Discreet Vaping - In order to experience the best of both worlds without reducing flavour or cloud production it is best to opt for a 50/50 blend.

Classic E-liquids                                                                                                                           

“Classic” e-liquids are those juices that contain a higher level of PG than VG and are therefore slightly thinner in consistency than the high VG e-liquids. The higher 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. These juices are best paired with low powered devices and perfect for all day vaping.

 

50/50 E-liquids                                                                                                                               

These juices contain an equal amount of PG and VG which allows them to be used in a variety of vape kits whether you are looking to use a vape pen or venture into the world of sub-ohm vaping. These e-liquids have been created for both MTL (mouth to lung) vaping to replicate the experience of smoking a cigarette whilst also being ideal for DTL (direct to lung) vaping making these versatile e-liquids.

The equal balance of VG and PG results in a perfect combination of vapour production and intensity of flavour making these an ideal choice for those beginning their vaping journey.

                                             

Sub Ohm E-liquids

Sub-ohm e-liquids contain a higher level of VG than PG and are therefore thicker in consistency than the classic e-liquids and 50/50 blends. This makes them an ideal choice for high powered devices that are able to produce large amounts of vapour. Sub-ohm vaping is generally practiced by hobbyist vapers looking to create billowing clouds of vapour so not the best choice for those trying to quit smoking.
