What is PG and VG?

PG (Propylene Glycol) and VG ( Vegetable Glycerine) are the two main components that make up an e-liquid.

They are the flavour carriers in an e-liquid and form the base of an e-liquid. Below we will discuss how the PG/VG ratio in your e-liquid affects the overall balance of your e-liquid.

Throat Hit and Vapor Production

The VG content of your e-liquid dictates the vapor production of your e-liquid when vapourized. The more VG in your e-liquid the more vapour is produced. PG provides more of a sensation in the throat and allows more flavour to shine through. In-between is some of each.

Viscosity (Thickness)

E-Liquid with a high percentage of VG will usually be thicker than those with a higher percentage of PG. The viscosity may effect how well the e-liquid works with various equipment. Some Atomizers tend to struggle to wick liquids which are high in VG as they tend to be much thicker.

Flavor and Sweetness

VG by nature tends to be sweet and will impart some sweetness on your e-liquid. However, VG tends to mute the added flavorings. A higher amount of PG in the mix tends to deliver better flavor. 

Conclusion

As you can see, the PG/VG ratio of your e-liquid can make a difference to the overall balance of your e-liquid. We find it's best to keep the VG ratio between 20-40% for best results.
