Your ultimate guide to e-cigarette liquids: understanding PG/VG ratios, nicotine strengths (freebase/salts), flavors, and choosing the best vape juice.
In the diverse and evolving world of vaping, e-liquids are the very essence of the experience. They are the alchemists' concoctions that transform a simple device into a source of flavour, sensation, and for many, an alternative to traditional smoking. The choice of e-liquid, often referred to as vape juice, e-juice, or vaping liquid, extends far beyond mere taste preference. It encompasses considerations of safety, user satisfaction, the desired vaping experience (from throat hit to cloud production), and crucial compatibility with your specific vaping device. Understanding the fundamentals of e-liquid composition, the various types available, and how to select the most suitable option is key to a fulfilling and safe vaping journey.
At its core, an e-liquid is a specially formulated solution designed to be heated by the coil (atomizer) within an e-cigarette, transforming it into an inhalable aerosol or vapor. While recipes can vary, the foundational ingredients are relatively consistent across the industry:
This carefully balanced mixture, contained within a vape tank, pod, or cartridge, is heated by the device's coil, turning it into the vapor that is then inhaled. This process avoids combustion, which is the primary source of harmful toxicants in traditional cigarette smoke, making vaping widely considered by public health bodies like Public Health England to be significantly less harmful than smoking.

The e-liquid market caters to a wide spectrum of user preferences and technical know-how. Understanding the different types of e-liquids available helps users avoid purchasing errors and allows for a more personalized and satisfying vaping experience.
Often referred to as "10mls" or standard e-liquids, these are pre-mixed solutions containing the base (PG/VG), flavourings, and a specified nicotine strength (or 0mg for nicotine-free options). They are sold in small bottles, typically 10ml, due to regulations in many regions (like the UK/EU's TPD/TRPR) that limit the size of nicotine-containing e-liquid bottles.
For the more experienced or adventurous vaper, concentrated flavourings offer the ultimate in customization. These are pure, undiluted flavour essences that must not be vaped directly as they are far too potent. They are designed to be mixed by the user with a neutral base liquid (a separate purchase of PG and VG, often pre-mixed in desired ratios like 70VG/30PG or 50VG/50PG) and, if desired, nicotine shots (10ml bottles of high-strength, unflavoured nicotine in a PG or VG base).
Shortfills (also known as "Shake & Vape" or "Mix & Vape") offer a popular middle ground between the convenience of ready-to-use liquids and the customization of full DIY mixing. These are larger bottles (e.g., 60ml, 120ml) containing nicotine-free e-liquid that is highly concentrated in flavour, with some empty space left at the top of the bottle. This space is designed for the user to add one or more 10ml nicotine "shots" (or nicotine-free base if they prefer 0mg) to achieve their desired overall nicotine strength and volume.
For example, a 50ml shortfill in a 60ml bottle allows for one 10ml nicotine shot to be added, typically resulting in 60ml of 3mg/ml e-liquid if an 18mg/ml nicotine shot is used.
Selecting the most suitable e-liquid involves balancing several personal preferences and technical considerations.
This is often the most subjective yet crucial factor. The "best" flavour is entirely down to individual taste. Common categories include:
The perceived intensity of a flavour can also be influenced by the PG/VG ratio. Higher PG liquids tend to carry flavour more distinctly, while high VG liquids, known for cloud production, can sometimes slightly dampen or "mute" the flavour intensity for some users.
Choosing the correct nicotine strength is vital for satisfaction, especially for those using vaping to quit smoking. Too low, and cravings may not be satisfied; too high, and it can cause harshness or discomfort (dizziness, nausea).
A general guideline based on previous smoking habits:
It's often a process of trial and error to find the perfect nicotine strength. Starting lower and adjusting upwards if needed, or vice versa, is a common approach.

The type of vaping device you use significantly influences the ideal e-liquid choice, particularly the PG/VG ratio:
Important Note: Using an e-liquid with an inappropriate PG/VG ratio for your device can compromise flavour, lead to leaking, cause coils to burn out prematurely, or result in an unpleasant vaping experience.
Once you've selected your e-liquids, proper storage and handling are crucial to maintain their quality, safety, and longevity:

Choosing the right e-liquid is a journey of discovery, blending personal taste with an understanding of how different components interact with your vaping device and your own preferences for nicotine delivery and sensation. Whether you opt for the simplicity of ready-to-use liquids, the customization of DIY mixing, or the balanced approach of shortfills, the key is to select high-quality, compliant products that suit your needs.
By considering flavour profiles, nicotine strength and type, PG/VG ratios appropriate for your hardware, and adhering to safe storage practices, you can significantly enhance your vaping experience, ensuring it is both enjoyable and responsible. Don't be afraid to experiment (safely and within regulatory guidelines) and consult with knowledgeable staff at reputable vape shops who can offer guidance tailored to your specific setup and preferences.
