For those of you who've been ordering liquid from us for a while now you may have noticed a change in our E-Liquid, not just in the bottle type and labels, but also in how it vapes. This is all to do with what we call PG/VG. Up until now we at Volcano have always gone for a 70/30 mix of PG/VG, but this is all now changing to a 50/50 mix. This all sounds incredibly complicated for most of us who might not look into our liquid past flavour and strength. I shall endeavour to explain exactly how it affects your experience here.
The E-Liquids that we like to vape so much are usually a base mixture of Propylene Glycol (PG) and/or Vegetable Glycerin (VG) with the flavouring and/or nicotine in whichever strength the user chooses. This allows the user to taste the flavouring and absorb any nicotine present through the vapour that they would inhale. Both PG and considered VG are considered perfectly safe and are in fact found in many of the foods we eat, cosmetics we use, medications we take, and in many household items like toothpaste and mouthwash. In fact, you can even find these ingredients in fog machines used in nightclubs and theatres.
PG is a thin liquid, diluting and carrying the flavour, making it the best base for mixing, though it is sometimes thinned out further through the adding of flavour and nicotine and may produce less vapour. Heavily PG liquids are recommended fro standard tanks that you may use. Some may find they have a sensitivity to PG, experiencing some irritation of the skin and throat, but most find that a lower PG liquid will overcome this.
In its pure form VG is a very sweet and thick liquid, causing it to produce a lot more vapour than PG. If the VG is too high then the downside is that it can cause wicking, clogging or burning issues in your device, so with a standard tank a VG-high liquid is not recommended. VG-based liquid is what is usually required for drippers and sub-tanks. Also, due to the inherent sweetness of VG it does tend to alter or dull the flavour slightly and reduce the amount of throat hit that you may experience.
At the end of the day the mixture is really a personal preference based on the difference between flavour, throat hit and vapour production. By changing our mix to 50/50 we are going for a balance between good flavour with a slightly lower throat hit and much higher vapour production. For now, if you receive a bottle with a white lid it's still 70/30 mix, but a black lid denotes our brand new 50/50 mix.
We hope you enjoy our new great flavours.
