Propylene Glycol (PG) / Vegetable Glycerin (VG)
So you’ve bought your first vape and you’re looking at different e-liquid flavours to buy and you notice on the label, PG/VG. What is PG/VG? And how does it affect my vaping experience? Here’s our Guide for Beginners on PG and VG.
What is PG/VG?
Propylene Glycol (PG) & Vegetable Glycerin (VG) are non-toxic organic liquids which form the base of most e-liquids for vaping. PG/VG is often used in everyday food products such as;
- Ice cream
- Fruit soft drinks
- Coffee beverages
- Salad dressing
Individually, the two e-liquids PG & VG have different characteristics which affect the end vaping experience for the vaper. You can group the traits into 4 main categories;
- Vapor Production
- Throat Hit (Harshness of the vapour)
Propylene Glycol (PG)
Let’s start with PG, the more popular base for e-liquids.
Flavour: PG is odorless and tasteless so it does not affect e-liquid flavouring.
Vapor Production: PG generally has lower vapour production compared to VG
Throat Hit: PG is humectant meaning it reduces the loss of moisture. This translate to a stronger hit to the back of your throat, similar to smoking a cigarette.
Viscosity: PG has a lower viscosity compared to VG. Having higher PG content makes your e-liquid more runny and readily absorbed by the atomizer and wick. Lower viscosity also translate to less residue within the tank which prolongs the lifetime of your coil.
Vegetable Glycerin (VG)
Next up, VG…
Flavour: VG has a slight sweet taste to the e-liquid. As a result, it may interact with flavouring and alter the end taste of the e-liquid.
Vapor Production: VG has higher vapour production compared to PG. A high VG base is responsible for large vapor clouds.
Throat Hit: VG has less of a throat hit which will be easier to smoke for beginners.
Viscosity: VG has a higher viscosity compared to PG. This means the e-liquid is a bit thicker and is absorbed slower by your atomizer and wick. This might mean filling up your tank and waiting a few minutes before vaping. Due to the higher viscosity, the e-liquid is prone to sticking onto the side of the tank and coil.
What PG/VG Ratio should I use?
There isn’t one PG/VG ratio that suits everyone, so it’s best to know what type of vaping experience you’re after and how to select your PG/VG ratio to suit.
Throat hit: If you want to replicate smoking a cigarette, choose a high PG ratio. We recommend a ratio of 70/30 PG/VG.
Smoothness: If you’re new to vaping and want a smoother experience to reduce any coughing, select a more balanced PG/VG ratio such as 50/50.
Flavour: If you’re an e-liquid connoisseur and enjoy experimenting with different flavours and aromas, select a high PG/VG ratio. We recommend a 70/30 blend.
Vapor Production: If you want to create as much vapor as possible to perform smoke tricks, choose an e-liquid with a high VG ratio. We recommend a 30/70 PG/VG blend.
