Understanding VG/PG Ratios

Choosing the right e-liquid is about more than picking a flavour you enjoy. One of the most important factors to understand is the VG/PG ratio. Vegetable Glycerin (VG) and Propylene Glycol (PG) are the two primary base ingredients used in e-liquid, and the balance between them can significantly influence vapour production, throat sensation, flavour delivery, and device compatibility.

Whether you’re new to vaping or looking to refine your experience, understanding VG/PG ratios can help you make a more informed choice.

What Are VG and PG?

Vegetable Glycerin (VG) is a thicker, slightly sweet liquid that produces larger, denser vapour clouds. E-liquids with a higher VG content are often preferred by people who enjoy a smoother inhale and substantial vapour production.

Propylene Glycol (PG) is thinner than VG and is highly effective at carrying flavour. It also tends to provide a more noticeable throat sensation. Higher-PG e-liquids can therefore appeal to vapers looking for a stronger, more pronounced inhale.

Because VG and PG offer different characteristics, manufacturers combine them in various ratios to create different vaping experiences.

Understanding Common VG/PG Ratios

You will commonly see e-liquid labelled with ratios such as 50/50, 60/40, 70/30, or 80/20.

50/50 VG/PG

A 50/50 e-liquid provides a balanced combination of flavour, vapour, and throat sensation. Its relatively thin consistency makes it suitable for many lower-powered devices and pod systems.

For beginners, a balanced VG/PG ratio can be a straightforward starting point because it offers an adaptable vaping experience without heavily favouring vapour or throat sensation.

60/40 VG/PG

A 60/40 blend contains slightly more VG, generally creating a smoother inhale and somewhat greater vapour production while still maintaining strong flavour performance.

This ratio can be a useful middle ground for vapers who want a little more vapour without moving to an especially thick e-liquid.

70/30 VG/PG

A 70/30 VG/PG ratio is a popular choice for cloud-focused vaping. The higher VG content usually produces thicker vapour and a smoother sensation.

However, because high-VG e-liquid is more viscous, it is typically better suited to devices and coils designed to handle thicker liquids.

Why Does the VG/PG Ratio Matter?

The VG/PG ratio can influence several aspects of your vaping experience:

• Vapour production: More VG generally means larger vapour clouds.
• Flavour delivery: PG is an effective flavour carrier and can provide a more pronounced taste.
• Throat sensation: Higher PG levels generally create a stronger throat feel.
• E-liquid consistency: VG is thicker, while PG is considerably thinner.
• Device compatibility: Different tanks, pods, and coils are designed for different e-liquid viscosities.

Understanding these differences makes it easier to match an e-liquid to your device rather than choosing solely based on flavour.

Choosing the Right E-Liquid

Before purchasing, consider your device, coil specifications, preferred vapour production, and the type of inhale you enjoy. A pod system may work better with a thinner blend, while a powerful sub-ohm setup may be designed for higher-VG e-liquid.

If you’re comparing products from a cheap vape store online, don’t focus on price alone. Check the VG/PG ratio, intended device type, nicotine information, flavour profile, and manufacturer details before making a purchase.

Final Thoughts

VG/PG ratios are a simple but important part of understanding e-liquid. Higher VG blends generally emphasise smoothness and vapour production, while higher PG blends tend to emphasise flavour intensity and throat sensation. Balanced ratios offer a middle ground for those seeking versatility.

By understanding what each ratio does, you can make more informed e-liquid choices and select products that are appropriate for your device and preferred vaping experience. Always follow the manufacturer’s recommendations and applicable age restrictions when purchasing or using vaping products.
