Why Just Juice Uses 50/50 for Nic Salts and Higher VG for Shortfills
Introduction
For anyone exploring e-liquids in the UK vaping market, one detail that often raises questions is why brands like Just Juice produce their nic salts in a 50/50 VG/PG ratio while offering shortfills with a higher VG content. At first glance, it might seem like an unnecessary distinction, but there is a clear technical and experiential reason behind it. The blend ratio in an e-liquid affects everything from flavour delivery and vapour production to throat hit and coil performance. This article will explore in detail why Just Juice has chosen this balance, what it means for your device, and how it enhances the vaping experience.
Understanding VG and PG Basics
Vegetable glycerine (VG) and propylene glycol (PG) are the two base ingredients that make up the majority of any e-liquid. VG is thicker and produces larger clouds of vapour, which makes it ideal for sub-ohm vaping and direct-to-lung devices. PG, on the other hand, is thinner and carries flavour more effectively, creating a sharper throat hit that mimics the feel of smoking. The ratio of these two components determines how the liquid behaves in your device and how the vapour feels when inhaled.
A 50/50 VG/PG blend, like that used in Just Juice Nic Salts, offers the best of both worlds. It allows for smooth vapour production without overwhelming coils in low-wattage pod systems. By contrast, higher VG blends, often found in shortfills, are designed for powerful devices that can handle thicker liquid and produce large clouds with less throat hit.
Why 50/50 is Ideal for Nic Salts
Nicotine salts are formulated to deliver nicotine more efficiently and with less harshness than traditional freebase nicotine. They work best at lower wattages and in devices with higher resistance coils, typically between 0.8 and 1.2 ohms. A 50/50 blend ensures that the liquid wicks properly in these small coils, maintaining flavour and avoiding dry hits.
If the VG content were any higher, the thicker liquid could struggle to soak into the cotton wick quickly enough, especially in compact pod systems. This can cause inconsistent vapour production, muted flavour, or even burnt coils. The 50/50 balance also supports the smooth, gentle throat hit that users expect from nic salts, making the overall experience more satisfying.
In addition, 50/50 e-liquids vaporise efficiently at lower power levels, which means better battery life for your pod device and a more economical vaping experience. This ratio is therefore practical as well as pleasant, aligning with the purpose of nic salts as a user-friendly option for those seeking a clean and consistent vape.
Why Shortfills Use Higher VG
Shortfills are designed for advanced vapers using sub-ohm kits or high-powered devices. These setups use lower resistance coils and operate at much higher wattages, which can handle thicker, more viscous e-liquid. A higher VG ratio, such as 70/30 or 80/20, is perfect for this kind of vaping because it creates denser vapour clouds and a smoother inhale.
Just Juice shortfills follow this convention because their audience is different from nic salt users. High VG blends work best in direct-to-lung vaping, where users inhale directly into the lungs, much like breathing in air. These vapers often prefer larger vapour clouds and less throat hit, which high VG provides naturally.
The reduced PG content also makes these e-liquids more suitable for users who may be sensitive to PG’s dryness or irritation. The higher VG ensures that the flavour remains rich and smooth, while the lower nicotine concentration (usually added via nic shots) keeps the overall experience balanced.
Performance and Device Compatibility
Device compatibility is one of the most critical reasons Just Juice separates its formulations. Pod systems, which are the preferred choice for nic salt users, are built with narrow wicking channels and low output power. A 50/50 blend flows easily through the wick and heats evenly, producing steady vapour and consistent flavour.
Shortfills, however, are intended for sub-ohm tanks and mods. These devices have larger coil openings, stronger batteries and more airflow, allowing for thicker high-VG liquid to flow smoothly without burning. Using a 70/30 shortfill in a small pod kit would clog the coil and cause dry hits, while using a 50/50 nic salt in a high-power mod would lead to excessive spitting and weak vapour.
By offering different VG/PG ratios, Just Juice ensures that every product performs optimally in its intended device type. This not only improves satisfaction but also protects the longevity of your coils and hardware.
Flavour and Vapour Differences
The VG/PG ratio influences more than just coil compatibility; it shapes the entire sensory experience. In 50/50 nic salts, the flavour is sharper and more pronounced because of PG’s ability to carry flavour compounds efficiently. The vapour is thinner and dissipates quickly, similar to smoke, making it an excellent choice for ex-smokers who prefer a discreet experience.
With high VG shortfills, the flavour is smoother and more rounded, while the vapour is thicker and lingers longer in the air. This difference appeals to cloud chasers and those who value visual impact as much as taste. The warmer vapour also gives a softer mouthfeel, which complements dessert or creamy flavours especially well.
Just Juice uses these principles to craft liquids that make sense for their intended audience. Their 50/50 nic salts are ideal for portable, on-the-go vaping with consistent flavour and satisfaction, while their high VG shortfills are for hobbyists and enthusiasts who enjoy fuller vapour and customisable setups.
The Science of Nicotine Delivery
Nicotine salts are absorbed into the bloodstream faster than freebase nicotine, providing a quicker nicotine hit similar to that of a cigarette. This property makes them effective for curbing cravings, which is why many ex-smokers prefer them. The 50/50 blend complements this feature by ensuring a smooth and efficient vapour at low temperatures, preventing the harshness that can occur when freebase nicotine is used in similar setups.
Shortfills, on the other hand, do not contain nicotine by default. Instead, users can add nic shots if they wish, giving them control over nicotine strength. The higher VG ratio ensures that even when nic shots are added, the liquid remains smooth and cloud-friendly. This makes shortfills appealing to both nicotine and non-nicotine vapers who prefer customisation.
Legal and Practical Considerations
Under UK and EU regulations, nicotine-containing e-liquids cannot be sold in bottles larger than 10ml. This is why nic salts come in small 10ml bottles. Shortfills, which contain no nicotine initially, can legally be sold in larger bottles, such as 50ml or 100ml, with space left for nicotine shots to be added.
The differing VG/PG ratios reflect this legal distinction and usage intent. Just Juice ensures that both product types remain compliant while optimised for their respective hardware. For the user, this means every product is not only enjoyable but also safe and legally sound.
Conclusion
Just Juice’s decision to use 50/50 VG/PG for nic salts and higher VG ratios for shortfills is a thoughtful balance of science, performance and user experience. The 50/50 blend guarantees smooth wicking, strong flavour and efficient nicotine delivery in low-wattage pod systems. The higher VG shortfills, on the other hand, cater to advanced users seeking rich vapour clouds, smooth texture and deeper customisation in sub-ohm kits.
Each formulation is designed with a purpose, ensuring that whichever style of vaping you prefer, you get the best possible experience. Understanding this difference not only helps you choose the right liquid for your device but also maximises coil life, flavour quality and satisfaction. Just Juice’s approach proves that when it comes to e-liquid formulation, balance and precision make all the difference.
