What are PG and VG? 

Basically, e-juice is composed of different ingredients such as PG and VG (two odorless liquids), nicotine (unless you chose the nicotine-free options), and flavorings. Both PG and VG produce vapor when heated, and this allows them to be easily inhaled. However, they have different consistencies and slightly different tastes.

Most modern e-liquid types use a combination of PG and VG, but most times at different ratios.

Generally, the FDA considers both PG and VG to be safe substances. Once you understand the differences between PG and VG, you can decide on the proportion of each component in each vape.

Note that choosing the wrong PG/VG ratio can put you off completely from vaping. So, you need to be careful in choosing the right level for you. Don’t worry; we will show you some great suggestions in this article.

Before then, let’s take a closer look at these e-liquid components separately:

What is PG?

PG stands for propylene glycol, and it is the e-liquid element that gives you the “throat hit” similar to what you get from smoking tobacco.

This organic compound has a slightly sweet taste and has a thinner consistency compared to VG. It also carries more flavor than VG. That’s why it is used commonly as a suspension fluid in products like flavor concentrates and nicotine.

Apart from e-liquids, PG has can be found in different products such as toothpaste, ice cream, and make-up wipes, pet foods, hand cream, and soap.

What is VG?

VG stands for vegetable glycerine, and it is the part of your e-liquid that produces the vapor. Just like PG, VG is colorless and odorless, but it is a lot thicker than PG. Also, it has a slightly sweet taste.

Apart from e-liquids, you can encounter vegetable glycerine in products like cough syrup, food colorings, and aftershave amongst others.

What are the roles of PG and VG in e-liquids?

Just like we’ve mentioned above, PG is the e-liquid component that holds in the flavor and gives you the kind of “throat hit” every ex-smoker craves. When you use e-liquids containing a high amount of PG, you will get some sort of visible vapor but it cannot be compared to the huge thick clouds produced from a higher VG ratio.

VG is the e-liquid component responsible for the production of huge vapor clouds. It helps to deliver a smoother overall vape, countering the harshness encountered sometimes with PG.

What Ratio of PG & VG is right for you?

Like we mentioned earlier, e-liquids are produced with different ratios of PG and VG. However, there is no one-size-fits-all approach to choosing the right ratio. It all depends on the kind of vaping experience you prefer.

Here are some of the factors to consider when choosing the right level of PG and VG:


If you prefer a much smoother feeling in your throat, high VG fluids are the best option. These VG fluids can have a slightly muted flavor when you use more power to produce more vapor.

It is advisable, however, that you stay within the wattage/voltage limits of your atomizer. Failure to do so can increase your risk of having dry hits or damaging your equipment.

Throat hit

A high PG vape e-liquid give a sharp throat hit when vaping. So if that’s what you enjoy, you can go for this instead of the VG-dominant e-liquid types.

A high PG vape will gives you the “kick” at the back of your throat – this is something most ex-smokers crave. Also, PG carries flavor better than VG, giving your vape a slightly improved flavor.

However, if you find high PG e-liquids to be too harsh on your throat, you can switch to a high VG. With time, a throat hit may become less important to you and you may find the high VG highly pleasant.

Cloud chasing

If you are desire to exhale dense clouds of vapor, a high VG vape e-liquid is the only option. This helps a lot in replicating a genuine smoking experience.

There are competitive events that are centered on cloud chasing and the person producing the biggest clouds gets the winning prize. If that is your aim, you should opt for higher VG vapes.

When using a high VG vape e-liquid, however, you need to allow time for the liquid to soak the wick. Nonetheless, this might not be a problem with the rebuildable atomizers and sub-ohm tanks as they tend to have much more effective wicking.

Stealth vaping

You may want to keep your vaping lowkey in public settings without drawing the attention of other people. A high PG vape e-liquid is the best option for this purpose. It produces less vapor when you exhale, and this makes it ideal for the less ostentatious vaping enthusiast.

However, always note that vaping in certain places such as inside public transport or waiting rooms, is often categorized as bad manners. You have to consider laws and behave responsibly as vaping is relatively new.

Looking at these factors above, you’ll notice it all down to personal preference. Do you want to get the best flavor or throat hit? Try a high PG vape e-liquid. Or perhaps you want to exhale huge clouds of vapor? Then try a high VG e-liquid.

Final Remark

Both PG and VG are important e-liquid components, and they serve different purposes. PG gives the “throat hit” that is similar to what you get with smoking tobacco. The VG component produces plumes of vapor that are likened to a steam train. Your choice, however, is based on your personal preference.

The factors listed above should guide you in choosing the right ratio of PG/VG. If you’re still clueless, you can try the 50/50 standard ratio. This balances a satisfying throat hit with a delicious flavor. Once, you’ve tried this option, you’ll be able to determine whether you need a higher PG or a higher VG.
