The Ultimate Breakdown of PG vs VG Vape E Juices

When looking for the best e juice, it’s important to understand the differences between PG vs VG Vapor and how it can affect the way your vaping as well as e juice flavoring.

Sinful Smores, White Gold, and Bango Smoothie. These are just some of the popular e liquids over at VaporFi , a popular and cheap e juice craft company.

Similarly, Halocigs also offers a wide selection from all kinds of categories. And it’s great!

These are just a few of the thousands of flavors that we get to choose from when shopping for our next bottle of e juice. 


In fact, having a wide variety of flavors is one of the best perks of vaping.

There is a lot more to choosing an e liquid than just flavor. You also have to consider other factors such as nicotine content and PG/VG ratios.

For example, both VaporFi and Halo offer premium lines of quality juice, but don’t offer many options to adjust the PG and VG ratio. 

VG and PG are particularly important, since they play a significant role in how any juice vapes.

In fact, I’d say it is just as important as flavor. Understanding the differences is vital to buying e juice you’ll love.

What Exactly is PG and VG?

First things first, let’s go over what PG and VG actually are. PG stands for Propylene Glycol and VG stands for Vegetable Glycerin. 

Both of these substances are already used in thousand of products we use every day.

Propylene glycol (PG) is an organic glycerol made frompg vs vg propylene oxide, a petroleum byproduct.

It is used in a wide variety of products including solvents, chemical additives, and many medical and pharmaceutical personal care products.

The U.S. Food and Drug Administration (FDA) has classified PG juice under the “Generally Recognized As Safe” designation.

Vegetable glycerin (VG) is a natural organic glycerol that is made from vegetable oil, which comes from palm and/or coconut oil.

The vegetable glycerin is mixed with water, then heated to a high pressure and temperature. The glycerin dissolves from the fatty acids and is then absorbed by the water.

Food grade VG is 99.7% pure, and 0.3% water. Vegetable glycerin can be found in pharmaceutical, medical and personal care products, and of course e liquids!

Difference Between PG and VG

PG juice is tasteless and clear, which presents the added flavor from your e juice very well.

PG juice also has a thinner, less viscous consistency than VG juice.

This means it tends to build up less gunk on the coil of your atomizer then VG juice.

The thin consistency makes it easily absorbed by the polyfill material when using cartomizers, allowing the juice to constantly reach the coil.

VG on the other hand has a naturally sweet flavor, which can sometimes be noticed when vaping VG juices.

Unlike PG liquids, the thicker, more viscous VG juice can sometimes clog up the coil on your clearomizer or cartomizer.

Of course, you can always clean your clearomizer. Plus, the extra thick VG juices are less likely to leak from your tank.

What is The Difference in Vapor Production?

Best Vapor Production

If you are interested in huge clouds of vapor, then VG is the way to go.

100% VG e liquid flavors have great vapor production and a very smooth feel.

Great for impressing your friends or doing cool smoke tricks!

If producing thunderz clouwdz has no particular appeal to you, you should definitely consider some PG juices. 

Many enjoy the combination of light vapor and clean taste.

Plus, PG flavors are useful when you’re vaping in public and don’t want to draw attention with large vapor clouds.

Which Has More Throat Hit?

PG juices will have a stronger throat hit then VG flavors.

There are many vapers who started vaping to help them quit smoking traditional cigarettes.

These vapers tend enjoy a stronger throat hit, similar to what you experience when smoking cigarettes.

If you don’t like a throat hit, then you should look for VG e juice flavors.

100% VG juices have extremely little if any throat hit, and have a very smooth feel when you are vaping.

How to Find Your Perfect Ratio

If you’re new to the vaping community, I suggest starting with some 50/50 (PG/VG) ratio juices.

This will give you a baseline flavor profile to work with and get a feel for the differences between VG and PG.

PG and VG MixesAfter vaping some 50/50 juice, you can start adjusting your mix to hone in on your tastes.

After awhile, you’ll get a better idea of the flavors, VG/PG ratio and nicotine levels of juice you enjoy.

If you’re feeling adventures, Zamplebox has a fantastic e juice subscription plan that opens you to tons of new juice brands and flavors.

The following explains what to expect from different PG and VG ratios.

These aren’t absolute laws, and are just to give you a general idea of what to look for.

  • 100% PG: Very strong throat hit, with clean flavors and not much vapor production.
  • 80/20 (PG/VG): Still very little vapor production, and a moderately strong throat hit.
  • 70/30 (PG/VG): A little more vapor, a little less throat hit.
  • 60/40 (PG/VG): Decent vapor with a noticeable, but not to overwhelming throat hit.
  • 50/50 (PG/VG): An even mix, with quality vapor clouds and a soft throat hit.
  • 40/60 (PG/VG): Noticeably larger vapor clouds and a reduce throat hit.
  • 30/70 (PG/VG): Good vapor production and a minimal throat hit.
  • 20/80 (PG/VG): Excellent vapor production and a very small throat hit.
  • 100% VG: Very little throat hit, with noticeably sweet flavor undertones and massive vapor production.

Let’s Sum It Up

PG and VG are the two primary components that go into e juices. PG juice is thin, clear and tasteless, and provides a more of a throat hit.  

VG juice is thicker, and has a naturally sweet taste that can blend into the flavor of the juice. VG has less throat hit, but a much higher vapor (cloudz) production.

    I know this is an old thread but I just wanted to chime in here and comment for those that may benefit from it. I started out using 50/50 and found that the PG gave me a really sore throat and I coughed all night. I switched to 70vg / 30pg and found this did not happen anymore but I still coughed sometimes while vaping. I was sub-ohm vaping at .03ohm and 30-40 watts. I found that if I vaped 3mg NIC with a 70vg / 30pg mix I was good. If I tried to up it to 6mg NIC I would cough until I had a head rush. I thought ok, let me try 100% VG and 9MG NIC. I coughed like I took a bong hit !! For me it turned out that the NIC Content affected me worse than the PG it seemed.
    I tried 6mg NIC and 70vg/30pg and it was tolerable at times but in the end I lowered the NIC to 3mg NIC 70vg/30pg and it was just right for sub-ohm vaping. I was however able to use my cartomizer at higher NIC levels without a problem so I use my sub-ohm at 3mg NIC and my Ego AIO at 6mg or higher NIC. I sometimes vape 100% VG with 3mg NIC in my sub-ohm but I find I need to increase my flavors to 15% when it’s 100VG so I think that 70vg/30pg 3mg NIC is my sweet spot. I find it best to mix my own e-juice as I can control exactly how much PG and NIC I get. I am in control. If you are not ready yet to mix your own NIC just get a premix of Base VG/PG and what ever level of NIC you can tolerate or Zero NIC. It’s all up to you. Just my 2 cents.

      Thanks for the heads up. I already figured I’d go 100% VG. My story startes a few years back when a friend of our kids’ was staying with us, and he vaped. I’m a former smoker and appreciated the lack of the tobbacco smell, and quite honestly, enjoyed the almost incence like smell of the chocolate hazel nut juice he preferred. One day I said wth, et me try that. One of the reasons I am a former smoker is severe Asthma. Well, one deep full hit and a nice slow exhale and I was proverbally hooked. I felt my chest open more than it does when using my rescue inhaler. But wait! No shakesm no rapid heart beat. But it did loosen up the deep mucous like the inhaler does, making breathing easier. That day I went and bought my first clearomizer based Ecig. this was about 4 years ago, I now have a collection of ecigs and a couple mods, and for the first time since that day, tis past week Ive had to use my inhaler as a result of a severe lung infection, Normally straight menthol works best when I am having asthma issues, but this infection has me coughing so hard I tore a muscle…
      I use zero nic fluids but have had a hard time finding the flavors I want recently so its time to u the game. I have the flavors on hand, coffee, chocolate and mint, and some “belgian waffle” juice to doctor at first. but plan on picking up some VG to make my own choc mint and mocha,
