With the ever-growing variety of e-liquids on the UK market, choosing the right one can feel overwhelming especially for vapers seeking a smoother, more satisfying experience. But the key to unlocking a better vape often lies in a single factor: the PG/VG ratio.
This guide breaks down what that ratio means, how it affects your vaping experience, and what to consider when choosing between options like 50/50 e-liquids and freebase nicotine. Whether you’re new to vaping or simply looking to fine-tune your setup, understanding the science behind e-liquid composition can help you make better, more personalised choices.
What Is PG/VG in E-Liquids?
E-liquids typically consist of four main ingredients: propylene glycol (PG), vegetable glycerine (VG), flavouring, and nicotine (optional). PG and VG form the base of all e-liquids, but they serve very different purposes.
- Propylene Glycol (PG): A thinner liquid known for its ability to carry flavour and deliver a stronger “throat hit” a sensation that mimics the feeling of smoking.
- Vegetable Glycerine (VG): A thicker, sweeter substance that creates denser vapour clouds and offers a smoother inhale.
The PG/VG ratio on your bottle such as 50/50, 70/30, or 80/20 indicates the proportion of each. This ratio dramatically influences everything from flavour clarity to throat hit and vapour production.
Why the PG/VG Ratio Matters
1. Throat Hit
If you’re looking for a sharper, cigarette-like throat hit, higher-PG blends are the way to go. This is often preferred by ex-smokers who want a familiar sensation. On the flip side, high-VG e-liquids tend to feel much smoother and gentler.
2. Flavour Intensity
PG is better at carrying flavour than VG. A balanced 50/50 ratio offers a nice compromise retaining rich flavours without sacrificing smoothness. This makes it ideal for both beginners and experienced users who want an all-rounder e-liquid.
3. Vapour Production
For cloud chasers, high-VG e-liquids (such as 70/30 or 80/20) are preferred, as they produce thicker, more voluminous vapour. However, they’re best used in sub-ohm devices with high wattage capabilities.
The Case for 50/50 E-Liquids
One of the most versatile e-liquid types is the 50/50 blend, which offers an even split between PG and VG. These liquids are particularly well-suited to mouth-to-lung (MTL) devices such as pod kits, starter kits, and vape pens.
Why go 50/50? Because it strikes a balance that works for most vapers:
- Smooth yet noticeable throat hit
- Solid flavour delivery
- Moderate vapour production
- Compatible with most low-powered vape devices
If you’re looking for a wide selection of expertly crafted 50/50 e-liquids, the Just Juice 50/50 collection is a great place to start. With a variety of fruit and menthol flavours, these TPD-compliant e-liquids are ideal for everyday use.
Understanding Freebase Nicotine
Another factor that significantly affects your vaping experience is the type of nicotine used. The two main types are freebase and nicotine salts.
Freebase nicotine is the more traditional form. It has a higher pH level, which results in a stronger throat hit at higher concentrations something many former smokers appreciate.
Freebase is typically found in lower nicotine strengths (3mg to 18mg) and is most effective in 50/50 e-liquids. It’s excellent for vapers who want:
- A satisfying throat hit
- Precise nicotine control
- Flavour accuracy
Those who prefer customisation and flexibility might find that freebase e-liquids offer a more adaptable and traditional vaping experience.
Device Compatibility: Why It Matters
It’s not just about the e-liquid; the device you’re using will influence how well a particular ratio performs.
- Low-powered pod systems and MTL kits: Best suited to 50/50 or higher-PG liquids. These devices are designed to replicate the draw of a cigarette and benefit from thinner, more flavour-rich liquids.
- High-powered sub-ohm devices: Better matched with high-VG liquids (like 70/30) to produce large vapour clouds. However, these require more power and consume e-liquid faster.
Using a high-VG liquid in a small MTL device may result in poor wicking, dry hits, and leakage. Conversely, using a high-PG liquid in a sub-ohm device can produce harsh, burnt-tasting vapour.
Factors to Consider When Choosing E-Liquid
To ensure a smooth and enjoyable vape, take into account the following:
- Your Vaping Goals
Are you quitting smoking, chasing clouds, or simply looking for a flavourful and convenient experience? - Your Device
Match the e-liquid’s PG/VG ratio to your device specifications. Check the coil resistance and wattage range. - Nicotine Strength
If you’re vaping frequently, lower nicotine (3mg or 6mg) in freebase form may be ideal. For stronger, quicker hits, consider nicotine salts (10mg or 20mg). - Flavour Preference
High-PG liquids tend to offer better flavour clarity. If you’re flavour-focused, a 50/50 or 60/40 blend can give you the best of both worlds.
Perfecting Your Vape: Choosing the Right E-Liquid for You
Vaping is not one-size-fits-all, and the perfect e-liquid is the one that matches your needs. From throat hit to vapour clouds, the PG/VG ratio plays a defining role in how you experience each puff.
Choosing the right e-liquid isn’t just about flavour it’s about comfort, satisfaction, and optimising your setup for a consistent, smooth vape. By understanding the interplay between PG, VG, nicotine type, and device compatibility, you can make smarter, more informed choices that elevate your vaping journey.
Whether you’re after a smoother throat hit, intense flavour, or cloud production, the UK vape market has an option tailored for you. Start with trusted, user-focused retailers like Freesmo, who not only offer a range of high-quality products but also the expertise to help you choose wisely.
