What is PG and VG in Vape? Everything You Need to Know

Have you ever noticed those PG/VG numbers on your e-liquid bottle? These figures actually determine how your vape feels, tastes and performs. Let's explore what PG and VG are and why they matter to your vaping experience.

What Are PG and VG?

PG stands for Propylene Glycol, and VG stands for Vegetable Glycerin. These two liquids make up about 90% of what's in your vape juice, with the rest being flavourings and possibly nicotine.

Both substances are considered safe and are used in many everyday products. They carry the flavour and create the vapour when heated in your device.

PG (Propylene Glycol): The Flavour Carrier

PG is a thin, clear liquid that plays several important roles in your vape juice. We've found that customers new to vaping often notice its throat hit first. It's that satisfying sensation at the back of your throat when you inhale – similar to what you'd feel when smoking a cigarette.

What makes PG special is how well it carries flavour. Despite having almost no taste itself, it delivers those complex flavour notes that make vaping enjoyable. The thin consistency means it works brilliantly in smaller devices like pod systems, where coil openings are tiny.

In our shop, we've noticed customers who use high-PG liquids often reach for their water bottle more often. This is perfectly normal – PG has a slightly drying effect on the mouth and throat. You'll find PG in many common products including asthma inhalers, food items (as E1520), and cosmetics.

VG (Vegetable Glycerin): The Cloud Creator

VG is the thicker, syrupy component in your e-liquid. When customers come to us asking for "bigger clouds," we immediately point them toward higher VG liquids. That's because VG is responsible for those satisfying plumes of vapour that many vapers enjoy.

Unlike its thinner counterpart, VG feels much smoother on your throat. If you've ever found vaping a bit harsh, switching to a higher VG liquid often solves the problem. It has a naturally sweet undertone, which is why very high VG liquids sometimes have a slight sweetness even without added flavours.

One thing to keep in mind: VG's thickness means it needs more power to vaporise properly. That's why it performs best in sub-ohm devices with bigger wicking holes and higher power settings. VG comes from plant oils and appears in many foods (as E422) and cosmetics.

Common PG/VG Ratios and Their Effects

The numbers on your e-liquid (like 50/50 or 70/30) show the percentage mix of PG and VG. Here's how different ratios affect your vaping:

50/50 Mix (Half PG, Half VG)

A 50/50 mix gives you a balanced vaping experience. The PG provides good flavour and throat hit, while the VG adds a satisfying amount of vapour. This ratio is perfect for beginners and works well in most starter kits and pod systems.

If you like mouth-to-lung vaping (drawing vapour into your mouth before inhaling to your lungs), 50/50 liquids are an excellent choice. They're also good with both regular nicotine and nic salts. If you're new to vaping or want a simple solution without worrying about PG/VG ratios, our disposable vapes are pre-filled with optimized e-liquid blends and require no maintenance.

70/30 Mix (70% VG, 30% PG)

This higher VG ratio provides:

• Smoother throat feel with less harshness

• Bigger, denser clouds

• Good balance between flavour and vapour

• Best performance in sub-ohm devices

The 70/30 ratio is popular with direct-to-lung vapers who inhale the vapour straight to their lungs in one smooth breath. It works best with lower nicotine levels (3-6mg) and more powerful devices.

80/20 or Max VG (Mostly VG)

These very high VG liquids are designed for serious cloud production. They deliver a very smooth vape with massive clouds but somewhat muted flavour. They require powerful devices with good wicking capabilities and are only suitable for low nicotine levels.

Choosing the Right Mix for Your Device

Using the wrong PG/VG ratio can lead to a poor vaping experience. Here's how to match your ratio to your device:

For Pod Systems & MTL Devices (Coils above 1.0 ohm)

These smaller devices work best with 50/50 or higher PG content. Their small wicking holes and lower power output are designed for thinner liquids. Using high VG liquids in these devices often leads to dry hits and burnt coils because the thick liquid can't wick fast enough.

For Sub-ohm Tanks (Coils below 1.0 ohm)

Sub-ohm devices are built for 70/30 or higher VG content. They have larger wicking holes and operate at higher powers, allowing them to handle thicker liquids efficiently. Using high PG liquids in these devices can cause leaking and may deliver an overly harsh throat hit.

PG Sensitivity: What to Watch For

Some people find they're sensitive to PG. If you experience any of these symptoms, you might be among them:

• Unusually dry mouth or throat (beyond normal PG dryness)

• Persistent sore throat

• Skin rash or irritation

• Headaches

If you suspect PG sensitivity, try increasing your water intake first. If symptoms persist, consider switching to a higher VG liquid (70% VG or more). For severe sensitivity, look for 100% VG liquids specially formulated for those with PG intolerance.

Which Mix is Right for You? Simple Decision Guide

Not sure which ratio to choose? After helping hundreds of customers find their perfect mix, we've developed this simple guide:

Do you want:

• Want convenience without worrying about PG/VG ratios? → Try our Elux vape that come with perfectly balanced e-liquid

• A stronger throat hit like smoking? → More PG (50/50 or higher PG)

• Smoother vaping with bigger clouds? → More VG (70/30 or higher VG)

• To use a basic starter kit or pod system? → 50/50 works best

• To use a more powerful sub-ohm device? → 70/30 or higher VG is better

If you're just starting, a 50/50 mix is a safe bet that works well in most basic devices. We've found that most new vapers appreciate the balance it offers between flavour and vapour production. As you become more experienced, you might want to experiment with different ratios to find your perfect balance.

Safety Tips

While PG and VG are generally considered safe, remember these important precautions:

• Keep all e-liquids in their child-proof bottles and away from children and pets

• Wash hands if you get e-liquid on your skin

• Be especially careful with nicotine-containing liquids

• Store in a cool, dark place to preserve flavour and quality

Conclusion

Now that you understand the basics of PG and VG, you're better equipped to choose the perfect e-liquid for your needs. Finding your ideal ratio is often a journey – many of our customers start with 50/50 blends and gradually explore different options as they discover their preferences.

Most vapers settle into their sweet spot with either 50/50 or 70/30 ratios, depending on their device and vaping style. For those who prefer simplicity and convenience, our Lost Mary vape come ready to use with optimized PG/VG ratios for a satisfying experience straight out of the box.
