When it comes to PG and VG ratio it can be understandably confusing selecting the best e-liquids for your new vape kit. In this guide we will try to break down what you should think about and what PG and VG means. E-Liquids are usually made up with two main ingredients, PG and VG. They will create the “foundation” of your e-juice in combination with 2 or 3 more ingredients, the latter being food flavouring, distilled water and nicotine.
What is PG and VG?
Propylene glycol (PG)
PG stands for Propylene glycol, it is a thin liquid that works as a flavour carrier and flavour enhancer in your e-liquid. By it self PG produces very little visible vapour and the more PG an E-liquid contains, the thinner it will be. PG also help with the throat hit and whilst nicotine is the main component in the e-liquid providing throat hit, higher PG E-liquids provide a better/stronger throat hit than higher VG E-liquids.
PG intolerance and allergies
Yes, some people have an intolerance to PG and it is estimated that around 4% of the population have a sensitive to PG. Usually this will present it self with light sinus symptoms and/or dry mouth, dry eyes, wheezing or even nausea. Although much rarer, some people even have an allergy to PG, as always if you are experiencing any strange side effects see your GP and try to arrange an allergy test. For vapers with a PG intolerance, higher VG e-liquid is the best choice and luckily there are even 100% VG e-liquids for those that are very sensitive or even allergic to PG. Vape green stocks the largest selection of 100% VG e-liquids in the UK/EU including our own 100% VG Vape Green E-Liquid line.
Vegetable glycerine (VG)
Vegetable glycerine is thicker than PG, the main job of the VG in your e-liquid is to produce vapour “clouds”. The more VG an E-liquid contains, the thicker the e-liquid will be and the bigger the clouds will be. High VG e-liquids containing over 50% VG are usually aimed towards more experienced vapers using high wattage vape kits and tanks with sub-ohm coils. These coils have large wicking holes, as high vg e-liquid is thicker the larger holes ensures that the cotton inside the coil is always saturated. Using a high PG e-liquid with such as kit / coils is not recommended as it would most likely result in leaking and a generally bad experience.
Best PG/VG ratio E-Liquid for Beginners.
For beginners the classic e-liquid mixture of 50% PG and 50% VG is the best. These “higher” PG E-liquids are formulated for usage with basic starter kits and pod kits. The 50%+ PG mix ensures that the e-liquid is thin enough so that the coils used in these types of vape kits can saturate properly without any dry hits. There are 2 main types of E-liquids we recommend for beginners and new vapers and those are:
50 50 E-Liquids are exactly what they sound like, a mix of 50% VG and 50% PG, they are generally available in a range of nicotine strengths from 3mg all the way up-to 18mg. We recommend starting in the middle with something like 6mg and then buy a higher or lower strength depending on personal preference.
Nicotine Salt E-liquids
Nicotine Salts also known as Nic Salts usually also come in 50% VG and 50% PG ratio blends. Nic salts look and work the same as “normal” e-liquids with the added benefit of providing a much smoother throat hit at higher nicotine levels. Normally higher nicotine strength over 12mg can be quite harsh but with nic salts most vapers can start at 20mg straight away making it perfect for anyone just getting of cigarettes. Due to the smooth throat hit nic salts offer most, if not all disposable vape bars come prefilled with nicotine salt. Disposable vapes are a great choice for anyone that wants to try out vaping as these usually cost £5 or less, each vape bar is equivalent of a pack of cigarettes or two.

Best PG/VG ratio E-Liquid for Experienced vapers.
For experienced vapers using sub-ohm gear we recommend using high vg e-liquids. Normally something with a 60%+ VG ratio, these e-liquids are usually formulated for usage with vape kits utilizing coils with large wicking holes. As these kits produces more vapour they are vaped at much lower nicotine strengths, with the most common being just 3mg. We recommend using Shortfill E-Liquids paired up with a nicotine shot for those who like to vape with nicotine.
