What Is PG/VG Ratio And Why Does It Matter?
Vaping has been one of the best innovations in nicotine therapy in the last 20 years. The main ingredients are propylene glycol (PG), vegetable glycerine (VG), water and flavourings, all heated up and inhaled in a substance that takes out the dangerous chemicals in tobacco smoke and replaces them with great tastes and a 95% safer nicotine alternative.
The simplicity of the ingredients still adheres to specific quantities and balances, from flavour to flavour and the PG and VG concentrations can differ in many ways. Below is a guide about PG and VG.
Propylene Glycol (PG)
PG is one of the two compounds that are used in the creation of e-liquids and is responsible for the taste and viscosity of vape liquid, whilst also carrying the nicotine. High PG ratio vape liquids usually mean that there’s more of a throat hit, higher nicotine concentration and a stronger taste, giving more space for nuance and depth to the flavours.
Vegetable Glycerine (VG)
Vegetable glycerine is another compound on which e-liquids are built on. VG increases the thickness of the vape liquid, making vape inhales denser. VG also brings a sweet taste, smoothing out the throat hit produced and creating larger vape clouds.
Mixtures and ratios
All e-liquids come with a ratio of PG to VG, measured in percentages of 100. Companies such as Nicohit provide a number of options to help you find the perfect mix for your own personal tastes.
Which is best for you?
High PG e-liquids are usually reserved for higher nicotine concentrations and simpler devices. These are best for first-time vapers and ex-smokers, looking for a simple nicotine hit over the complexities of variable vaping. Whether it be a vape pen or a pod mod, the simplicity and throat hit of the high PG vape liquid will attract beginners and those looking to sample more striking tastes.
High VG e-liquids are the go-to for the seasoned vaper. These are usually lower in nicotine but suit higher powered vape devices. Whether sub ohming or using variable wattage/voltage and temperature controls, the flexibility of these devices give you the chance to inhale larger amounts of vapour in a technique called direct to lung vaping.
