Here are our PG / VG bases from the manufacturer Vapor Flavour.

The abbreviation of propylene glycol is PG and the abbreviation of vegetable glycerin is VG.

The PG is very liquid it is him which hangs the flavours and which gets the hit (sensation of passage in the throat)

The VG is thicker and is necessary for the vaporization of e-liquid. It brings roundness and a little sweetness to your e-liquid and promotes the production of steam.
