The Quick Answer
PG (propylene glycol) is the thin one. It carries flavor and gives your throat a little kick. VG (vegetable glycerin) is the thick one. It makes big, soft clouds.
Every bottle of vape juice blends the two, and the ratio changes how it vapes. Our classic Juice Head vape juice runs 70/30 (VG-heavy for clouds and smoothness), and our salts run 50/50 for small pod setups.
When it comes to vaping, two little letters come up constantly: VG and PG.
They sound like twins. They are not. And knowing the difference is one of those things that quietly levels up your whole vape game.
Never really got a straight answer on what they mean? No worries. That is exactly what we are here for.
In this guide, we break down VG vs PG in plain English: what each one does, how the ratios work, and how to match a blend to your setup so every pull tastes the way it should.
Let's dive in.
One quick thing before the deep dive. Every blend we talk about below already lives in our vape juice lineup, mixed and dialed in for you. So you never have to measure a thing. Now, let's meet the two liquids doing all the work.
What Are PG and VG?
Start with the basics.
PG and VG are the two liquids that make up the "base" of every bottle of vape juice. Think of the base as the body of the juice. It carries the flavor, and the nicotine if you use it, and it is what actually turns into vapor when your coil heats up.
The two letters, decoded
- PG: short for propylene glycol. The thin, runny one. Carries flavor and delivers the throat hit.
- VG: short for vegetable glycerin. The thick, syrupy one. Builds big, dense clouds.
- The base: PG and VG blended together. Flavor and nicotine ride on top in much smaller amounts.
- The ratio: how much of each is in the bottle, written like 70/30. It changes how the juice vapes more than almost anything else.
Nearly every juice you will ever try uses both. The magic is in the mix.
So let's take each one on its own first.
What Is Propylene Glycol (PG)?
Propylene glycol, or PG, is a colorless, thin liquid with a barely-there sweet taste.
Its job in vape juice is to be the flavor courier. PG grabs onto flavoring and nicotine and spreads them evenly through the bottle, so every pull tastes like the last one.
Because it is thin, PG turns to vapor easily and gives you that crisp little push at the back of the throat that many vapers look for. Vapers call that the throat hit.
More PG means sharper flavor and a stronger throat hit, with lighter, thinner clouds.
What Is Vegetable Glycerin (VG)?
Vegetable glycerin, or VG, is the opposite personality. It is a thick, syrupy liquid made from plant oils, with a naturally sweet edge.
VG is the cloud machine. Because it is dense, it vaporizes into those big, soft, billowy plumes that hang in the air.
It also smooths the whole pull out. More VG means an easier, rounder hit with less bite.
The tradeoff? VG is a little slower to carry flavor, and its thick body can build up on a coil faster, especially with rich, sweet blends. Nothing a fresh coil does not fix, but worth knowing.
VG vs PG: Compared Side by Side
Here is the whole matchup on one card. Same two liquids, very different jobs.
| Trait | VG (vegetable glycerin) | PG (propylene glycol) |
|---|---|---|
| Consistency | Thick and syrupy | Thin and runny |
| Clouds | Big, dense, billowy | Lighter and thinner |
| Flavor delivery | Softer, more muted | Sharp and concentrated |
| Throat hit | Smooth and gentle | Crisp and strong |
| Coil buildup | More, especially with sweet blends | Less |
| Feel of the pull | Round and easy | Bright with a little bite |
See the pattern? VG is the body and the clouds. PG is the flavor and the kick.
Neither one is "better." The right answer is the right ratio, and that is where it gets fun.
VG makes the clouds. PG carries the flavor. The ratio decides your whole pull.

How the Ratios Work
Every bottle of juice lists its blend as two numbers, like 70/30. The first number is almost always the VG.
Why does the ratio matter so much? Because the consistency has to be just right for your coil to turn it into vapor. Too thin and it scorches fast. Too thick and it struggles to wick and vaporize at all.
And here is the plain truth: there is no single perfect ratio for everybody.
Some vapers chase clouds. Some chase maximum flavor. Some want the strongest throat hit they can get. Each of those pulls the ratio in a different direction, and you cannot max out all three in one bottle.
That is not a flaw. That is the fun part. You get to pick your lane.
Which Ratio Is Right for You?
Good news: you never have to mix a drop yourself. Juice comes pre-blended in a handful of common ratios, and once you know what each one gives you, the label tells you everything.
| Blend | What you get | Best for |
|---|---|---|
| MAX VG | The thickest clouds around, slow to burn through | Dedicated cloud chasers |
| 90VG/10PG | Huge clouds with a bit more flavor coming through | Clouds first, flavor second |
| 80VG/20PG | Massive plumes plus generous flavor and a noticeable hit | Cloud lovers who refuse to skimp on taste |
| 70VG/30PG | Bold flavor, a satisfying throat hit, and plenty of vapor | The all-around sweet spot (our classic blend) |
| 60VG/40PG | Flavor takes the lead, clouds ease off | Flavor-first vapers |
| 50VG/50PG | Maximum flavor and a crisp hit in a thin, pod-friendly juice | Small pods and salt nic (our salts blend) |
| MAX PG | The most intense flavor and the strongest throat hit, light clouds | Pure flavor chasers |
One more thing, though. The ratio is only half the equation. The other half is the gear you run it in.
Match Your Gear to Your Blend
Here is the one rule that covers most of it:
The golden rule of ratios and wattage
- More VG: run higher wattage. Thick juice needs more heat to vaporize well.
- More PG: run lower wattage. Thin juice scorches if you cook it too hot.
- Sub-ohm tanks: happiest around 70VG or higher. Big airflow, big coils, big clouds.
- Small pods: built for thinner 50/50 blends that wick fast in tight spaces.
A couple of guardrails. Crank a MAX VG juice at super-high wattage and you will burn through a bottle surprisingly fast. Run a PG-heavy juice too hot and you will scorch it and taste it immediately.
And if you put a thick 80VG juice in a tiny pod, the wick cannot drink it in fast enough. That is how you end up with dry, scorched pulls that ruin your day.
Match the juice to the gear, and everything just works. Which brings us to the easy part.
The Blends We Pour, and Why
We took all the guesswork above and baked it into two blends.
Our classic 100ml e-liquids, including every Freeze flavor, run 70/30. We landed there on purpose. It is the sweet spot where the fruit tastes bold, the pull stays smooth, and the clouds still show up. If you run a sub-ohm tank, this is your lane. Start with a crowd-pleaser like Peach Pear and you will taste exactly what we mean.
Our salt nic e-liquids run 50/50 in 30ml bottles. That thinner blend wicks perfectly in small pods and puts the flavor right up front, like Pineapple Grapefruit Salts on a lunch break.
Two blends, two setups, zero math on your end.
VG and PG FAQs
What do VG and PG stand for?
VG is vegetable glycerin, the thick liquid that makes big clouds. PG is propylene glycol, the thin liquid that carries flavor and gives the pull its crisp throat hit. Together they form the base of every vape juice.
Which is better, VG or PG?
Neither. They do different jobs. VG brings clouds and smoothness, PG brings flavor and kick. The right question is which ratio fits how you like to vape and what gear you run.
What ratio is Juice Head vape juice?
Our classic 100ml e-liquids and Freeze flavors run a 70/30 VG/PG blend for bold flavor, smooth pulls, and full clouds. Our 30ml salt nic e-liquids run 50/50 for small pod systems.
What does 70/30 mean on a bottle?
It is the VG to PG ratio, with VG listed first. A 70/30 juice is 70 percent vegetable glycerin and 30 percent propylene glycol, which lands in the sweet spot of flavor, smoothness, and vapor.
Can I use a high-VG juice in a small pod?
We would not. Thick, VG-heavy juice wicks slowly, and tiny pods cannot keep up, which leads to dry, scorched pulls. Pods do their best work with thinner 50/50 blends like our salts.
Does a high-VG juice wear out coils faster?
It can, especially with rich, sweet flavors, because the thicker liquid builds up on the coil over time. Keeping your tank topped up and swapping coils when flavor fades keeps everything tasting fresh.
What wattage should I use for my blend?
The simple rule: more VG, higher wattage; more PG, lower wattage. Sub-ohm tanks like 70VG and up. If you are running a 50/50 or 60/40 blend, keep the power modest so the juice never scorches.
