Introduction
Choosing the right e-liquid is one of the most important decisions a vaper makes. Beyond selecting a flavor you enjoy, you must also consider the base ingredients that determine how the liquid performs in your device. High VG (Vegetable Glycerin) vape juice has become the standard for many enthusiasts, particularly those who enjoy dense vapor and a smooth experience. At Vapor Authority, we provide a wide range of US-made e-liquids to help you find the perfect balance for your specific hardware.
Understanding the difference between Vegetable Glycerin (VG) and Propylene Glycol (PG) allows you to customize your experience to your exact preferences. This guide will explore what defines a high VG liquid, how it interacts with different types of hardware, and why it remains a top choice for the vaping community.

Consult a physician if you have concerns about whether vaping products are appropriate for you.
Defining High VG Vape Juice
To understand high VG vape juice, you must first understand the two primary base ingredients used in almost all e-liquids: Propylene Glycol (PG) and Vegetable Glycerin (VG). These two liquids act as the carrier for nicotine and flavorings. While they are both colorless and odorless, they have very different physical properties.
Vegetable Glycerin is a thick, viscous liquid derived from vegetable oils, typically palm, soy, or coconut oil. It has a slightly sweet natural taste. Because of its thickness, it requires more heat to vaporize and produces a much denser, thicker cloud of vapor compared to PG.
A "high VG" vape juice is generally defined as any e-liquid where the VG content is 70% or higher. Common ratios include 70/30 (70% VG and 30% PG), 80/20, or even "Max VG." Max VG does not necessarily mean 100% VG; rather, it means the manufacturer used the highest possible amount of VG while still including the necessary PG-based flavorings and nicotine.
VG vs. PG: The Core Differences
The ratio of VG to PG in your e-juice completely changes the character of your vape. For many years, higher PG ratios were the norm because early vaping hardware was not powerful enough to vaporize thick liquids. As technology evolved, high VG became more popular.
Propylene Glycol (PG) Characteristics
Propylene Glycol is much thinner than VG. It is an excellent carrier of flavor and provides a "throat hit," which is the tingling sensation in the back of the throat. High PG liquids are generally used in low-powered devices and pod systems because the thin liquid wicks easily into small coils.
Vegetable Glycerin (VG) Characteristics
VG is significantly thicker, with a consistency similar to syrup or liquid honey. Because it is thicker, it does not provide the same sharp throat hit as PG. Instead, it offers a "smooth" inhale, even at higher wattages. This makes it the preferred choice for those who want to produce large vapor clouds without irritation.
The Practical Effects of High VG Blends
When you switch to a high VG liquid, you will notice several immediate changes in your vaping experience. These changes affect everything from the volume of vapor you produce to how often you need to replace your coils.
Enhanced Vapor Production
The most notable feature of high VG juice is the cloud production. If you are using a sub-ohm tank or a rebuildable atomizer, high VG is essential for creating those large, dense plumes of vapor. The thick nature of the glycerin allows it to hold its shape as vapor more effectively than PG.
Smoother Throat Hit
Many vapers find that high PG liquids can be too harsh on the throat, especially when used with high-powered mods. High VG solves this by providing a much softer sensation. Even if you are vaping at 80 or 100 watts, a 70/30 or 80/20 VG/PG blend will feel much smoother than a 50/50 blend.
Subtle Sweetness
Because VG has a natural sweetness, it can slightly alter the flavor profile of your e-liquid. It tends to make dessert and cream flavors taste richer and more "full." However, because VG is a less efficient flavor carrier than PG, some complex fruit or tobacco notes might feel slightly more muted compared to high PG versions of the same juice.
Hardware Compatibility: Who Should Use High VG?
Not every device is designed to handle the thick consistency of high VG vape juice. Using a thick liquid in the wrong device can lead to "dry hits"—the unpleasant taste of burnt cotton—because the liquid cannot move into the coil fast enough.
Sub-Ohm Tanks
Sub-ohm tanks are the most common hardware paired with high VG juice. A sub-ohm tank is any tank that uses a coil with a resistance of less than 1.0 ohm. These tanks feature large wicking ports—the holes in the side of the coil where the cotton is visible. These large ports allow thick VG liquid to flow freely into the heating element.
Rebuildable Atomizers (RDA and RTA)
Experienced vapers who use Rebuildable Dripping Atomizers (RDAs) or Rebuildable Tank Atomizers (RTAs) almost exclusively use high VG liquids. Because these users build their own coils and manually wick them with cotton, they can tailor their setups to handle maximum VG levels for competitive cloud production and intense flavor.
Pod Systems and Starter Kits
Most compact pod systems are designed for higher nicotine strengths and thinner liquids, such as 50/50 ratios. If you put a Max VG liquid into a small pod, the tiny wicking holes may struggle to absorb the juice. This often results in the coil burning out prematurely. If you use a pod system, always check the manufacturer’s recommendations before using a liquid higher than 70% VG.
Nicotine Strengths and High VG
The way nicotine behaves in high VG liquid is different from how it behaves in high PG or nicotine salt liquids. Because high VG juice is almost always used in high-wattage, sub-ohm devices, the amount of vapor you inhale per puff is much higher.
Freebase Nicotine
High VG liquids typically use freebase nicotine. Because you are inhaling a large volume of vapor, you do not need a high concentration of nicotine to feel the effects. The most common nicotine strengths for high VG juices are:
- 0mg: Nicotine-free, used by those who enjoy the flavor and clouds only.
- 3mg: The most popular strength for sub-ohm vapers.
- 6mg: A standard choice for those who want a more noticeable throat hit and higher nicotine intake.
Using high-strength nicotine (like 18mg or 50mg nicotine salts) in a high VG sub-ohm setup is generally avoided, as the sheer volume of vapor would make the experience extremely harsh and provide far too much nicotine at once.

Maintenance and Coil Longevity
One trade-off of using high VG vape juice is the impact on your coils. Because VG is thick and often contains natural or artificial sweeteners, it can lead to "coil gunk."
Coil gunk occurs when the sugars in the e-liquid caramelize on the heating element instead of vaporizing completely. Over time, this creates a black, crusty layer on the coil that ruins the flavor and reduces vapor production. To maximize the life of your coils when using high VG juice:
- Prime your coils: Always let a new coil sit in a full tank for at least 10 minutes to ensure the thick VG has fully saturated the center of the cotton.
- Stay within the recommended wattage: Every coil has a suggested wattage range printed on the side. Exceeding this can burn the thick liquid onto the cotton.
- Avoid chain vaping: Giving the coil a few seconds between puffs allows the thick liquid to re-wick into the cotton.
Battery Safety for High-Powered Vaping
High VG vaping often requires box mods and external batteries to provide the necessary power. When using these devices, battery safety is not optional—it is a critical part of the hobby.
Practical Battery Safety Tips
- Inspect the Wraps: Always check the thin plastic "wrap" around your batteries. If there is a nick, tear, or hole, do not use the battery. Exposed metal can cause a short circuit.
- Use a Dedicated Charger: While many mods have USB ports, it is always better to use a high-quality external charger. This ensures your batteries charge evenly and extends their overall lifespan.
- Use Matched Pairs: If your device takes two or more batteries, "marry" them. This means buying them at the same time and always using/charging them together so they age at the same rate.
- Storage: Never carry loose batteries in your pocket or bag. If they touch coins or keys, they can vent. Always use a plastic battery case for transport.
Storing Your High VG E-Liquid
To keep your high VG juice tasting fresh, proper storage is essential. Because VG is an organic compound, it can degrade over time if exposed to the wrong conditions.
- Temperature: Keep your juice in a cool, dry place. High heat can cause the liquid to thin out too much, while extreme cold can make it so thick that it won't wick properly.
- Light: Direct sunlight and UV rays can cause the nicotine to oxidize, which turns the liquid a dark brown color and can result in a peppery, unpleasant taste.
- Safety: Always store your e-liquid in a high cupboard or locked container away from children and pets.
Is High VG Right for You?
Choosing a high VG e-liquid is a matter of personal preference and the hardware you own. If you enjoy the ritual of blowing large clouds and prefer a smooth, creamy inhale, high VG is likely the best choice for you. However, if you prefer a compact device that mimics the sensation of traditional smoking with a sharp throat hit, a higher PG ratio or nicotine salt e-liquids might be more appropriate.
Many vapers find that a 70/30 VG/PG ratio is the "sweet spot" for modern vaping. It provides enough thickness for great clouds while still maintaining enough PG to deliver clear, crisp flavor and manageable wicking in most sub-ohm tanks.

FAQ
Can I use high VG vape juice in any device?
No, high VG juice is generally too thick for small pod systems or older "clearomizers" with tiny wicking holes. These devices usually perform best with 50/50 or high PG liquids. Using high VG in a small device often leads to dry hits and burnt coils.
Why does high VG produce more vapor?
Vegetable Glycerin is much denser than Propylene Glycol and has a higher vaporization point. When heated, it creates a much thicker and more stable aerosol, which results in the large, white clouds that characterize sub-ohm vaping.
Does high VG juice gunk up coils faster?
Generally, yes. Because VG is thicker and often paired with sweeteners to enhance its natural sweetness, it can leave more residue on the coil's heating element. This caramelization eventually requires you to replace the coil to maintain flavor quality.
What is the best wattage for 70/30 VG/PG e-liquid?
The best wattage depends on your specific coil's resistance, not just the juice. However, most 70/30 liquids perform best between 40 and 80 watts in a sub-ohm tank. Always check the "recommended wattage" range engraved on the side of your coil head.
