Is it Important to Pay Attention to PG and VG?

For any vaper, preferences for e-juice (or e-liquid) flavors are quite personal. Some prefer sweeter more dessert-y flavours while others might not. But the one thing that’s common in either of these e-liquids is the ingredient that exist in them apart from flavouring. Of course, we are referring to PG and VG.

A big question that always comes up is exactly what PG and VG refers to and how are they different. Well, you have come to the right place. Hopefully by the time you read through this blog you will have a clearer idea of what each term means, and which might be more suitable for you.

PG (or Propylene Glycol) and VG (or Vegetable Glycerin) are the only ingredients combined with flavouring in e-liquids. When considering shopping for e-liquids, you might prefer VG and PG, and in specific ratios.

Though e-liquids are pretty cool with the wide range of flavours in which they are available or even the addition of nicotine or CBD in them, these are not the only considerations for vapers when choosing one for themselves. The PG and VG ratio should also be taken into account. But before delving into this further, let’s understand how they differ.

Difference Between PG and VG

If you have used PG before in your e-liquid, you might have noticed that it creates less cloud (or vapour) and the liquid is clear and less viscous. One more defining feature of PG is that it is totally tasteless. This is why e-liquids that have a higher concentration (or ratio) of PG have much sharper and defined flavours.

VG, on the other hand, creates a lot more vapour than PG. It is also more viscous than PG liquids. This is particularly the case in e-liquids that contains a ratio higher than 70% VG. As for its taste, VG, unlike PG, has a naturally sweeter taste. And this is why in e-liquids that have a higher ratio of VG, consumers might find it a lot sweeter.

Both PG and VG are odorless and classified as sugar alcohols. They are included in various consumable products. In vapes, when heated they produce vapours that can be inhaled. Apart from the distinction in their viscosity, vapour production and flavor, PG and VG also have distinct mouth and throat sensations.


Depending upon your preferences, you might be more inclined to choose e-liquids that have a higher concentration of PG or VG. Now that you know what they are and how they differ, your consumer decision might be influenced by a few aspects. For one, give the difference in their consistencies, PG liquids are less inclined to build up gunk on the coil of your atomizer, and may be more likely to leak.

For VG liquids, due to its thicker viscosity, it might require you to clean it more often. This is because it might sometimes clog up the coil on your tank. But on the more positive side, VG liquids are less likely to leak from the tank.

Another consideration might be the vapour production. For those interested in creating huge cloud of vapour, VG liquids are going to be preferred over those with more PG.

The other consideration, as discussed earlier, is the ratio.  You might need to experiment a bit with the ratios if you are a beginner to be able to find one that works for you. For a cleaner and less sweet flavor you might be more inclined towards e-liquids with a  higher PG ratio.  The ratios can really make a difference.

For those looking to use vapes as an alternative to smoking, throat hit (or throat sensation) may be a big deal. PG has more of this throat hit than VG that some vapers claim is similar to the throat sensation experienced when smoking.

So, Which One Should I Choose? Well it really depends upon what you like. If you are unsure, experimenting is the way to go. You might want to start off with a 50/50 ratio in your e-liquids and then make adjustments in your next order. This way you can expand your palate and make an informed decision.
