What is VG and PG? [A Detailed Guide]
PG and VG are the two main ingredients in vape juice. This guide will explain what PG and VG is and how it impacts your vaping experience. We will also run through the benefits of each while suggesting the best ratio to suit different vaping styles. Firstly, lets explain the difference between these two e-liquid components.
What is VG?
VG (vegetable glycerine) is a much thicker liquid than PG, and is designed to produce vapour when heated. The higher the VG level the thicker and bigger the clouds of vapour. This ingredient comes in higher concentrations in vape juice designed for cloud chasers, as these people usually want to produce as much vapour as possible.
What is PG?
PG (propylene glycol) is a thinner liquid, and is the main component that creates the 'throat hit' sensation when vaped. This ingredient is more prominent in vape juice designed for MTL (mouth-to-lung) vaping as the higher concentration delivers a sensation close to smoking.
Is VG and PG Safe for the Human Body?
Both propylene glycol and vegetable glycerine are considered non-toxic and safe. These ingredients can also be found in food, cosmetic and pharmaceutical products where safety is paramount.
Understand Your Ratios
When vaping, the VG:PG ratio is one of the biggest factors to take into consideration when picking the right e-liquid. Both ingredients offer completely different characteristics so finding the right ratio to suit both the vape kit and technique is crucial to achieving the best vaping experience.
A balanced 50/50 e-liquid is the most common as it can be used with virtually any vape kit. It is also suitable for both MTL and DL vaping as it provides an even split of throat hit and vapour. When used with more powerful devices it won’t be too harsh and with low powered devices the flavour and throat hit is still prominent.
As this is the most popular ratio with vapers there are plenty of ranges to choose from. One of the stand-out e-liquids is Vampire Vape. The 10ml range offers a huge selection of over 50 flavours to choose from, including multiple award-winners.If this balanced mix is the right PG:VG ratio for you then shop our full range of 50/50 vape juice.
High VG E-Liquids
E-liquid with a high VG content is designed for vapers who want to produce more vapour. The thicker consistency makes it limited to sub-ohm vaping as high resistance coils struggle to wick high VG vape juice. When vaped at a higher wattage this type of e-liquid provides a quality flavour with a thick cloud of vapour and smooth throat hit. One of the best high VG e-liquids is the Double Drip short fill. Coming in a 50ml shortfill bottle it offers enough vape liquid for multiple days of DL (direct-lung) vaping. Plus, the ‘max VG’ ratio of 80:20 VG/PG provides the thickest vapour production perfect for cloud chasing.

How Does Nicotine Impact the Eliquid?
As MTL and DL use different amounts of e-liquid, the nicotine strengths should differ to account for this. MTL vapers should only require one 10ml bottle of e-liquid for a day of vaping, so the strength should be how much nicotine they require for the day. DL vapers however will not require as high a nicotine strength as they consume more e-liquid, so multiple bottles of weaker e-liquid would be more suitable.
Which VG PG Eliquid is Best for You?
New vapers who are unsure if they prefer MTL or DL vaping should choose a 50/50 vape juice, as this will provide enough PG and VG to cater to both techniques. Most vapers start with the mouth-to-lung technique as it closely resembles the method of smoking combustible cigarettes. Those who decide to venture into more powerful direct-lung vaping can stick with the same 50/50 e-liquid but will start to prefer high VG vape juice once they want to produce thicker clouds of vapour with a smoother throat hit.
Does Vaping Equipment Impact the VG:PG Ratio?
Yes, it is important to use the right e-cig for the vape juice being used. E-liquid with a high VG content is designed for high power vape kits. This is because the VG content makes the vape liquid thicker which low powered pod kits struggle to absorb. This is because they use high resistance coils that can’t wick thicker e-liquid properly. This can result in dry hits and lead to the coil burning. Not only that, because the PG content is diluted the flavour and throat hit is weaker. This means that when it is used with a less powerful kit for MTL vaping, it will not be strong enough and might taste watered down.
Powerful mod kits use sub-ohm coils which have a low resistance. These coils usually come with larger wicking areas (the area with exposed cotton holes around the coil body) which allows them to absorb thicker e-liquid while heating up more vape juice at a quicker rate. This creates the desired vapour production, providing the intended flavour and throat hit from high VG e-liquid.
Alternatively, e-liquid with a high PG content should be used with low power mouth-to-lung vape kits. Although it can be absorbed easily by most coils, when vaped at a higher wattage the flavour will be unpleasant and the throat hit too harsh. This is because the stronger concentration of PG is designed to be vaped at lower wattages to provide enough nicotine and flavour to MTL vapers.
Does PG:VG Ratio Impact Nicotine Strength?
The required nicotine strength can differ depending on the PG:VG ratio. As vapers who use high VG e-liquid use more vape juice than MTL vapers, the strength of the e-liquid can be lower.
For example, a DL vaper using a 0.6% high VG vape juice can get the same amount of nicotine as an MTL vaper using a 1.2% 50/50 e-liquid. This is because the direct-lung vaper will use much more e-liquid as an MTL vaper. If the direct-lung vaper went through two 0.6% bottles of e-liquid it would provide the same amount of nicotine as one bottle of 1.2% vape juice. If you are switching to direct lung vaping it is important to remember this as sticking to the same e-liquid strength can deliver too much nicotine.
