The Science of VG PG?
What is VG PG?
This is an interesting question every new vapor is confused with. That being said, to put it in one sentence PG stands for Propylene Glycol, while VG stands for Vegetable Glycerin, Both odourless and colourless organic liquids. I know that is not the complete answer you were looking for. Lets discuss this in very simple way.
PG or Propylene Glycol: The substance in which eliquid’s flavourings dissolves. A good example will be, flour in the cake without it, nothing would mix together.
PG is thinner than VG, it also gives throat hit and helps your vape wick absorb the liquid. Pg will not clog your coils because of its thinner consistency.
VG or Vegetable Glycerin: VG provides the mouth taste. It’s the eggs and the butter. Without it, you’d just have sugary bread. It wouldn’t be rich, or moist. It would be a perfectly fine thing to eat, but it wouldn’t be as luxurious as you would perhaps hoped.
VG makes the things sweeter and it affect the flavour of the e-liquid. VG is thicker than PG. They do Clog the coils quite quickly but they create dense vapor clouds.
The vast majority of e-liquids will use a combination of PG and VG. The ratios used will be declared within the ingredients list.
Which one is the Best?
It depends person to person but here are some key point to consider before choosing any of them.
Best For Flavor is PG, If you want sharp (Throat Hit) flavour and you are not fussed about the amount of vapour produced, you would love a PG Liquid, As PG is totally tasteless, so it will not affect flavour. It keeps tobacco flavours toasty, mint flavours clean, and fruity flavours sharp. PG is a better flavour carrier than VG, and this means that the more PG, the more flavour is delivered.
Best For Clouds is VG, If you really want to enjoy the flavor and are ok for sacrificing a bit of flavour for the smoother sensation of the juice then look for High VG Flavours.
In summary Stick to PG for harsh throat hit and Choose VG if you lover sweet and creamy flavor with huge clouds.
