PG (Propylene Glycol) and VG (Vegetable Glycerine) are the two base ingredients in all e-liquids.

All e-liquids have set levels of PG/VG depending on the manufacturer, generally described as High PG or High VG liquids. Before you decide on which PG/VG levels we must look at the effects of both PG and VG.

First, we’ll look at PG (Propylene Glycol). When vaping PG it gives more of throat hit, feeling more like the effect of a cigarette, and is generally seen as the best way to help ex-smokers on their way to completely making the switch to vaping. It also lets off less vapour making it less noticeable when vaping in enclosed areas, PG also vaporizes better at lower temperatures and is generally preferred in starter devices or with higher resistance coils.

VG (Vegetable Glycerine) is a thicker, sweeter liquid than PG. Although it lacks in a throat hit, VG produces much more vapour than PG, giving a more satisfying effect when recreating the effect of the actual smoke from a cigarette. VG is also much more suited for vaporizing at much higher temperatures, and is better suited for larger, more advanced devices and sub ohm coils.

As a couple of examples of when is best suited to use high PG or high VG liquids I would say, for devices such as our SERIES-E with the Geni Tank that uses 1.8ohm coils, I would recommend high PG liquid. For devices such as our SERIES-S or our SERIES-B with Gille tank, which use lower resistance 0.5ohm coils, I would recommend high VG liquid.
