E-Liquids

What does "VG" and "PG" mean?

The terms PG and VG refer to the main ingredient that is used as a base for the liquid (the solvent). 

VG based e-liquid
VG liquid mainly has a Vegetable Glycerin base, which is derived from vegetables. Whilst a VG liquid mainly contains VG, it also requires some PG content to work too. It is therefore the ratio of VG to PG that determines how it is classified - more VG content generally results in a liquid that will be classified as VG. Some VG liquids are classed as 'pure VG' but they will usually still contain at least 20% PG.

The general characteristics of VG based liquid are:
  1. VG is thicker than PG
  2. VG tends to generate more vapour and tends to linger more
  3. VG generally gives a lesser throat hit and as a result is easier on the throat for all day vaping
  4. VG tends to have a sweeter taste than PG
 
(General comparisons are based upon equivalent PG liquid)


PG based e-liquid
PG liquid has a Propylene Glycol base, which is used in food flavourings and also in fog machines. Whilst a PG liquid mainly contains PG it also requires some VG content to work too. It is therefore the ratio of VG to PG that determines how it is classified - more PG content generally results in a liquid that will be classified as PG. Some PG liquids are classed as 'pure PG' but they will usually still contain at least 20% VG.

The general characteristics of PG based liquid are:
  1. Pg is thinner than VG
  2. PG tends to generate less vapour and disperses more quickly upon exhale
  3. PG generally gives a stronger throat hit but as a result can leave you with a dry throat with all day vaping
  4. A very small percentage of people exhibit a sensitivity to PG liquid and for that reason alone, prefer VG base instead.

Please note that these are general guidelines and as usual, It really does come down to individual preference - experiment to find what suits you best.
