Choosing the right e-liquid involves more than just finding a flavour you enjoy. The VG/PG ratio is another important factor that affects vapour production, flavour, throat hit, and overall device performance. Understanding these two ingredients can help you make a better choice when buying e-liquid.

VG stands for Vegetable Glycerine, while PG means Propylene Glycol. Both ingredients have different roles in an e-liquid. VG is mainly responsible for producing vapour, whereas PG helps carry flavour and provides a stronger throat sensation.

When selecting a 100ml Shortfill E Liquid, it is important to understand how different VG/PG ratios work. Some liquids are thicker and produce more vapour, while others are thinner and offer a different balance of flavour and vapour production.

In this guide, we will explain the common VG/PG ratios, their differences, and how to choose an option that matches your device specifications.

What Is VG in E-Liquid?

Vegetable Glycerine, commonly known as VG, is a thick liquid made from vegetable oils. It is one of the main ingredients used in e-liquids and is mainly responsible for vapour production.

VG has a slightly sweet taste and creates a thicker consistency. E-liquids with higher VG content generally produce larger vapour clouds and provide a smoother throat sensation.

However, thicker liquids may not work properly with every device. They need compatible coils and wicking systems to ensure the liquid reaches the heating element correctly.

What Is PG in E-Liquid?

Propylene Glycol, or PG, is a thinner liquid that helps carry flavour in e-liquids. It also provides a more noticeable throat sensation.

Unlike VG, PG produces less visible vapour. Its thinner consistency allows it to move easily through suitable coils and liquid channels.

The amount of PG in a 100ml Shortfill E Liquid can affect how the flavour is experienced and how the liquid performs in different devices.

Understanding Different VG/PG Ratios

VG and PG are mixed in different proportions to create e-liquids with different characteristics. Understanding these ratios makes it easier to compare products.

50VG/50PG Ratio

A 50VG/50PG ratio contains equal amounts of VG and PG. It provides a balance between vapour production and flavour delivery.

This mixture is generally suitable for compatible lower-powered devices and certain mouth-to-lung setups. Its thinner consistency allows it to work with coils designed for balanced VG/PG liquids.

60VG/40PG Ratio

A 60VG/40PG ratio contains slightly more VG than PG. It offers a middle ground between vapour production and flavour delivery.

The higher VG content helps create more vapour, while PG supports flavour delivery. This ratio may work with moderate-powered devices that support this liquid thickness.

70VG/30PG Ratio

A 70VG/30PG ratio contains 70% VG and 30% PG. It is a common choice for compatible sub-ohm devices.

The higher VG content helps produce thicker vapour, while the PG helps carry flavour. However, this liquid is thicker than a 50/50 mixture, so it needs a suitable coil and wicking system.

80VG/20PG Ratio

An 80VG/20PG ratio contains a high amount of VG. It is mainly intended for compatible devices that can handle thicker e-liquids.

This mixture can produce dense vapour, but its thick consistency makes device compatibility especially important. It should only be used when the device manufacturer confirms that the setup supports it.

Actual performance can vary depending on the e-liquid formulation, coil design, and device settings.

Which VG/PG Ratio Is Best for 100ml Shortfill E-Liquid?

There is no single VG/PG ratio that works for every device. The right option depends on your equipment and its recommended e-liquid requirements.

A 70VG/30PG mixture is commonly used in compatible sub-ohm devices because it offers good vapour production and flavour delivery. On the other hand, a 50VG/50PG mixture may be more suitable for certain lower-powered devices.

Before choosing a 100ml Shortfill E Liquid, check the manufacturer's recommendations. Using an unsuitable liquid thickness can affect coil performance and may lead to poor wicking or leaking.

Important Factors to Consider Before Choosing a Ratio

Your device specifications should always be considered before selecting an e-liquid. Here are two important factors to keep in mind.

1. Check Your Coil Type

Different coils are designed to work with different e-liquid thicknesses. Coils with larger liquid openings can generally handle thicker, high-VG mixtures.

Using a liquid that is too thick for your coil may prevent proper wicking. Always check the recommended VG/PG range before purchasing.

2. Understand Your Device Power

Device power also affects how an e-liquid performs. Some higher-powered devices are designed for thicker liquids, while lower-powered devices may require thinner mixtures.

However, wattage alone does not determine compatibility. Always follow the device manufacturer's instructions.

Does VG/PG Ratio Affect Flavour and Vapour?

Yes, the VG/PG ratio can influence both flavour delivery and vapour production.

PG helps carry flavour and can provide a more noticeable throat sensation. VG produces thicker vapour and has a slightly sweet taste.

For example, a 70VG/30PG mixture generally produces thicker vapour than a 50VG/50PG mixture. However, flavour quality also depends on the ingredients and overall formulation.

When comparing a 100ml Shortfill E Liquid, consider the complete product rather than focusing only on its VG/PG ratio.

Common Mistakes to Avoid When Choosing E-Liquid

Selecting an unsuitable ratio can affect your device's performance. Some common mistakes include:

  • Choosing high-VG e-liquid without checking whether the device supports thicker mixtures.
  • Assuming that higher PG always means better flavour.
  • Ignoring the recommended coil and device specifications.
  • Selecting a ratio only because it is popular.
  • Overlooking the manufacturer's storage and usage instructions.

Taking time to understand these details can help you make a more informed purchasing decision.

How to Store 100ml Shortfill E Liquid?

Proper storage helps maintain the quality of e-liquid. Heat, sunlight, and unnecessary air exposure can affect its flavour and condition.

Keep your 100ml Shortfill E Liquid in its original bottle and store it in a cool, dry place away from direct sunlight. Always close the cap properly after use.

Also, keep e-liquids away from children and pets. Follow the manufacturer's storage instructions and expiry information to maintain product quality.

Summary

Understanding the VG/PG ratio makes it easier to compare e-liquids and choose products that match your device specifications. VG mainly supports vapour production, while PG helps carry flavour and provides a stronger throat sensation. Ratios such as 50VG/50PG and 70VG/30PG offer different characteristics depending on the equipment being used.

Before selecting a 100ml Shortfill E-liquid, check its VG/PG ratio, product details, and device compatibility. Taking these factors into account can help you make a more informed choice.

Frequently Asked Questions (FAQs)

1. What VG/PG ratio is best for 100ml shortfill e-liquid?

The right ratio depends on your device specifications. A 70VG/30PG mixture is commonly used in compatible sub-ohm devices, while 50VG/50PG may suit certain lower-powered devices. Always check manufacturer recommendations before choosing.

2. Does higher VG produce more vapour?

Yes, higher VG generally produces thicker vapour clouds because Vegetable Glycerine is responsible for vapour production. However, the final result also depends on coil design, device power, airflow, and the overall e-liquid formulation.

3. Is 70VG/30PG suitable for every device?

No, 70VG/30PG is not suitable for every device. Its thicker consistency requires compatible coils and wicking systems. Check your device specifications before using this ratio to avoid poor wicking or other performance issues.

4. Does PG improve e-liquid flavour?

PG helps carry flavour and can make it more noticeable. However, flavour quality also depends on the ingredients and formulation. VG contributes to vapour production and has a slightly sweet taste.

5. Can I add a nicotine shot to a shortfill bottle?

Some shortfill bottles have extra space for suitable nicotine shots. However, always check the bottle capacity, manufacturer's mixing instructions, nicotine strength, and local regulations before adding anything to the e-liquid.
