VG vs PG Breakdown

PG vs VG – How They Affect E Juice Flavor, Clouds & More: The Ultimate Breakdown

PG (Propylene Glycol) and VG (Vegetable Glycerin), combined with flavoring are the only ingredients in e juice, so it’s actually pretty important to know the differences (and the ratios they are used  in) when shopping for e juice.

In a nutshell:

  • PG creates less clouds than VG, as it’s a generally less viscous fluid. But is completely tasteless, meaning e juice flavors with higher ratios of PG have sharper, more defined flavors.
  • VG creates waaay more vapor than PG, especially a flavor contains higher than 70% VG. However it also has an inherent ‘sweet’ taste to it, which can overwhelm the subtleties in a juice, especially for non-dessert flavors.

Having a wide variety of flavors is one of the best perks of vaping. But it’s not just the flavor and nicotine level you have to account for, and you should always be looking what the PG VG ratio of your juice is.

In fact, I’d say it is just as important as flavor. By that I mean if you had two vape juices with the same flavor, but very different PG/VG ratios you’re likely going to notice a difference.

It can can go as far as making a fruity lime flavor either taste tangy and crisp like the fruit, or mellow and decadent like a dessert.

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.

It also has a thin consistency, which makes PG heavy juices it more likely to leak in vaping or sub ohm tanks.

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 tank or RDA leading to flooding, requiring you to clean it more often.

On the flip side, the extra thick VG juices are less likely to leak from your tank.

PG vs VG 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?

While nicotine has the biggest affect than PG/VG ratios, it’s important to note that 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.=

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.

That said, you really need to try some different ratios yourself to really get a feel for the difference.

So be sure to experiment with your e juice every once in awhile so you can expand your pallet and become a more informed buyer, especially when shopping online where there aren’t any taste test available (duh!)

    I sure appreciate the info. I have been hitting the local vape smoke shops and shopping flavores. It’s been getting kind of expensive so I decided to see what I could find on the internet, that’s where I saw your info site. I was reluctant to shop internet because sometimes the juice would burn my throat and I don’t like that. I have found the people who work in some of these shops are not always good sources of information. Now I know what to look for! I think if I order a 80/20 I’ll be happy and save Alot of money. Thank you.

    I am a former smoker for last 10 years and recently started vaping about 10 months ago and i must say that i no longer have sinus headaches. i switched back to smoking for a couple for weeks as my mod broke and was waiting for a new one and in those two weeks i experience my sinus headache coming back. Ever since then i never touched a cig again. And stick with vaping now. Buying juice from stores could cost anywhere between 20 bucks to 100 bucks for a 30ml to 120ml bottles. So i decided to start making my own 6 months ago and have been vaping my own juice since then.

    With all that being said, i have done all types of ratio’s and found 85/15 vg/pg to be the best for me. Sometimes that can get trick as most flavors are 100%pg base. In those cases, i had to do 80/20 vg/pg and great clouds with amazing flavor. Just make sure you do 10-15% of flavor when making high vg juice.

    Good luck

    I have just made a 80/20 pg/vg, now I normally go with 80/20 vg/pg but I thought I would try the other way round. 5ml of nictotine and flavour. I will obviously have to wait a few days before using it on my sub ohm (Cleito 120) but I just I would ask if this will work? If not no matter, I have other juices I can use but I like to try variations. Let me know if I have done right or wrong

    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,
