If you've ever shopped for vape juice, you've probably noticed labels like 70/30 VG/PG or 50/50 VG/PG. While these numbers may seem confusing at first, they play a major role in determining your vaping experience. The ratio of Vegetable Glycerin (VG) to Propylene Glycol (PG) affects everything from vapour production and flavour intensity to throat hit and device compatibility.

Whether you're new to vaping or looking to improve your setup, understanding the difference between VG and PG can help you choose the right e-liquid for your needs. This guide explains how both ingredients work, their advantages, and which VG/PG ratio is best for different vaping styles.

What Is VG?

Vegetable Glycerin, commonly known as VG, is a thick, slightly sweet liquid derived from vegetable oils. It is widely used in food, cosmetics, and pharmaceutical products because of its smooth texture and ability to produce dense vapour.

In vaping, VG is responsible for creating the large clouds that many users enjoy. Because of its thickness, it requires more powerful devices and coils designed to handle higher-viscosity liquids.

Benefits of VG

High VG e-liquids offer several advantages:

• Produces thick, dense vapour clouds
• Provides a smoother inhale
• Slightly sweetens the flavour
• Ideal for cloud chasing
• Less harsh on the throat

These qualities make VG popular among experienced vapers using sub-ohm devices.

What Is PG?

Propylene Glycol, or PG, is a thinner, odourless liquid that has been safely used for decades in food products, medicines, and personal care items.

In vaping, PG acts as an excellent flavour carrier and delivers a stronger throat hit that closely resembles the sensation of smoking a traditional cigarette.

Benefits of PG

High PG e-liquids are known for:

• Better flavour clarity
• Stronger throat hit
• Faster nicotine delivery
• Excellent performance in pod systems
• Efficient wicking in smaller coils

These characteristics make PG a popular choice for new vapers and former smokers.

Understanding VG/PG Ratios

Every e-liquid contains a combination of VG and PG. The ratio printed on the bottle indicates how much of each ingredient is included.

Some of the most common blends include:

50/50 VG/PG

A balanced 50/50 ratio is one of the most versatile options available.

Benefits include:

• Balanced flavour and vapour
• Smooth wicking
• Compatible with most pod systems
• Suitable for nicotine salts and freebase nicotine
• Efficient coil performance

This ratio is ideal for beginners and everyday vaping.

70/30 VG/PG

A 70% VG and 30% PG blend is designed for larger vapour production.

Advantages include:

• Bigger clouds
• Smoother inhale
• Rich vapour density
• Excellent performance with sub-ohm tanks

Because it's thicker, this blend works best in high-powered vape devices.

High PG Blends

Liquids with a higher PG content focus on flavour and throat hit rather than cloud production.

They're often used in:

• Starter kits
• Pod systems
• Mouth-to-lung devices
• Higher nicotine strengths

How VG Affects Your Vaping Experience

VG changes several aspects of vaping.

Vapour Production

VG is primarily responsible for cloud size. The higher the VG content, the thicker and denser the vapour becomes.

This makes high VG liquids the preferred choice for users who enjoy producing large clouds.

Smoothness

VG creates a smoother inhale with less throat irritation, making it suitable for longer vaping sessions.

Coil Performance

Because VG is thicker, it requires coils with larger wicking ports to absorb the liquid efficiently.

Using high VG liquid in a device designed for thinner e-liquids may lead to dry hits or poor performance.

How PG Affects Your Vaping Experience

PG contributes to several important aspects of vaping.

Flavour Intensity

PG carries flavour molecules more effectively than VG, often producing brighter and more pronounced flavours.

Throat Hit

Many former smokers appreciate PG because it creates a noticeable throat hit similar to smoking cigarettes.

Nicotine Satisfaction

PG delivers nicotine efficiently, making it particularly effective in higher-strength e-liquids.

Which Ratio Is Best for Beginners?

For most beginners, a 50/50 VG/PG blend offers the best balance.

It provides:

• Good flavour
• Moderate vapour
• Smooth nicotine delivery
• Excellent compatibility with pod devices
• Reliable coil performance

Many nicotine salt e-liquids also use a 50/50 ratio because it performs well in low-powered devices.

Which Ratio Is Best for Cloud Chasing?

If your goal is producing impressive vapour clouds, high VG e-liquids are the better choice.

Most cloud enthusiasts prefer:

• 70/30 VG/PG
• 80/20 VG/PG
• Max VG blends

These thicker liquids work best in powerful sub-ohm devices capable of vaporizing larger amounts of e-liquid.

Matching Your E-Liquid to Your Device

Choosing the correct VG/PG ratio depends largely on your vape device.

Pod Systems

Pod devices usually perform best with:

• 50/50 VG/PG
• Nicotine salts
• Higher nicotine strengths

Sub-Ohm Devices

Sub-ohm kits are designed for:

• High VG liquids
• Lower nicotine strengths
• Larger vapour production

Using the wrong ratio may reduce flavour, shorten coil life, or cause leaking.

Tips for Choosing the Right E-Liquid

When selecting an e-liquid, consider:

• Your vape device
• Preferred nicotine strength
• Desired cloud production
• Flavour preferences
• Vaping style

Purchasing from the best online vape shop also helps ensure you're getting authentic products from reputable manufacturers. Trusted retailers offer a wide selection of VG/PG ratios, premium brands, and detailed product descriptions, making it easier to choose an e-liquid that suits your device and preferences.

Final Thoughts

Understanding the difference between VG and PG is essential for choosing the right e-liquid. While VG produces smoother inhales and larger vapour clouds, PG delivers stronger flavour, a more noticeable throat hit, and efficient nicotine delivery. Neither option is universally better the best choice depends on your device, vaping style, and personal preferences.

For most beginners, a balanced 50/50 blend provides an excellent starting point, while experienced users with sub-ohm devices may prefer higher VG ratios for increased cloud production. By matching your e-liquid to your vape device and experimenting with different ratios, you can enjoy better flavour, improved performance, and a more satisfying vaping experience.
