PG vs. VG: What’s The Difference & Which Should I Vape?

When most people buy ejuice they’re looking at three things: 1) what flavour you’re getting, 2) whether it is a PG or VG mix — or a bit of both and 3) the brand who made the juice (because some are definitely better than others). Flavour is one thing. Ditto the brand. But what the hell does PG and VG mean?

Let’s get the definitions out of the way first: PG stands for Propylene Glycol; VG stands for Vegetable Glycerin. These two chemicals are the odorless liquids that, when combined with flavouring and nicotine, create the ejuice. When heated these liquids produce vapor and that, boys and girls, is what you breathe in from the drip tip of your vaping setup.

But PG and VG are NOT the same. Both serve different purposes and create different types of vapor, as you will learn below.

PG vs. VG: What’s The Difference?

PG (Propylene Glycol)

PG and VG serve different purposes and create different types of vapor. PG-heavy mixes, for instance, give more of a throat-hit while VG is smoother on the throat, which is why a lot of professional or more-experienced users that build their own mods and coils tend to prefer it.

PG is less viscous than VG and it carries flavour better too. This is why a lot of brands tend to use it more liberally than VG. I personally like a good 80/20 VG/PG split because you get the best of both worlds: high wattage vaping, smooth hits and just enough of a throat hit to know you’re taking a hit. Your preference may differ, so I’d advise you to try out a few different types of mix in your local vape shop.

VG (Vegetable Glycerin)

VG — or, Vegetable Glycerin — is derived from vegetable oil and is quite a bit thicker than PG. It also has a slightly sweet taste as well and because the hit from VG liquids is smoother than PG, 100% VG mixes are often favoured by sub-ohm vapers.

Most ejuice — like 99% of the stuff — is a mix of both and, depending on where you shop and which brands you use, you can usually find something that suits your needs ideally. I started my vaping life with cheap stuff, but then soon discovered my local vape shop and began experimenting with better quality ejuice and different PG/VG compositions before finding my personal sweet spot — 80/20.

Is eJuice Safe?

This is a question I get asked ALL the time and for the sake of brevity I am not going to into the subject here. If you want to know more about ejuice safety and the latest research I suggest to you take a look in the Health section of VapeBeat. In there you will find mountains of information about ejuice and whether or not vaping is safe — it is, though, don’t worry! And there’s plenty of evidence to back up this claim as well.

Now you know the difference between VG and PG and how it affects the composition and flavour of your ejuice you might want to check out our guide to The Best eJuice Money Can Buy, where we detail all the best, new ejuice we’ve tried and tested.
