What Is E-Liquid?
E-liquid is the flavoured liquid used in e-cigarettes and vape kits. It is heated by a coil inside the device, turning into vapour that you inhale. E-liquid delivers flavour and nicotine, satisfying cravings without tobacco combustion or the tar and carcinogens associated with smoking.
What Is the Main Ingredient in Vape Juice?

E-liquids primarily consist of 95% VG and PG, forming the base of the e-liquid. The remaining 5% includes nicotine, flavourings, and other additives. A VG-only e-liquid exists for those who prefer nicotine-free, flavour-free options.
Food-grade flavourings offer a diverse range of taste experiences, from fruity blends to desserts. Nicotine, when present, provides the familiar sensation associated with smoking. Many vapers choose nicotine-free e-liquids for a purely flavourful experience. A well-formulated vape juice ensures a smooth inhale, rich flavour, and satisfying vapour production.
What Are VG and PG?
VG (Vegetable Glycerin) and PG (Propylene Glycol) are the two primary components in e-liquid. Each affects the vaping experience differently.
VG (Vegetable Glycerin)
VG (Vegetable Glycerin) and PG (Propylene Glycol) are the two primary components in e-liquid. VG is a thicker liquid that produces dense vapour. It delivers a smooth inhale and enhances the sweetness in flavours. High VG e-liquids creates bigger clouds and work best with sub-ohm devices and direct-to-lung vaping. PG, on the other hand, is a thinner liquid that carries flavour more effectively. It produces a stronger throat hit, resembling the sensation of smoking. High PG e-liquids delivers sharper flavours and a more noticeable throat hit. They are best suited for mouth-to-lung vapers and low-powered pod systems.

Different VG/PG ratios impact the overall experience. Higher VG creates bigger clouds, while higher PG delivers sharper flavours and a more noticeable throat hit. Many vapers experiment with different blends to find their ideal balance.

What Are the Different Types of E-Liquid?
The different types of e-liquids are listed below. Each is designed to suit different vaping styles.
Freebase Nicotine E-Liquids
A Freebase nicotine e-liquid is a vape liquid made with purified, deprotonated nicotine that delivers a stronger throat hit and a sensation similar to smoking. Its higher alkalinity enhances flavor intensity, making it ideal for users seeking bold taste and a classic vaping experience.
Nicotine Salt E-Liquids
Nicotine salt or salt nicotine e-liquid is a vape liquid made by blending pure nicotine with acids to form a smoother, lower-pH compound. This allows for higher nicotine strengths without harsh throat irritation, offering a gentle, satisfying experience ideal for low-wattage devices and discreet vaping.
Shortfill E-Liquids
A shortfill e-liquid is a large, nicotine-free vape juice bottle (usually 50ml to 200ml) designed with extra space to add nicotine shots. It offers flexible nicotine strength, making it ideal for advanced vapers using sub-ohm kits who prefer customization and smoother, high-vapor experiences.
50/50 E-Liquids
A 50/50 e-liquid is a balanced vape juice made with 50% propylene glycol (PG) and 50% vegetable glycerin (VG), offering equal flavor delivery and vapor production. It suits most vape kits and delivers a smooth throat hit with moderate clouds, making it ideal for everyday, versatile vaping.
High VG E-Liquids
A High VG e-liquid is a vape juice with a higher concentration of vegetable glycerin than propylene glycol, resulting in thicker consistency, smoother throat hits, and large, dense vapor clouds. It’s ideal for sub-ohm vaping with high-wattage devices and is favored by users who enjoy cloud chasing and softer inhales.
Choosing the right type of e-liquid depends on the vaping device, nicotine preference, and desired throat hit. Some vapers use different types for different occasions, switching between nicotine salts for a quick hit and high VG e-liquids for cloud production.

What’s the Cost of Vape Juice?
The cost of vape juice varies based on the brand, bottle size, flavour, packaging and design, nicotine type and strength, and taxes. There are basic 10ml e-liquids whose cost starts from just £1.20 each. On average, the cost of vape juice ranges from £3 to £6 for a 10ml bottle in the UK, but nicotine salt e-liquids tend to be priced higher. This is because they give a much smoother throat hit, which subjects the consumer to a quicker nicotine rush. Bigger bottles, such as shortfills on average (usually 50ml and 100ml), will be priced anywhere between £10 and £20, but again, these would need separate active nicotine shots added in. These will include premium or imported ingredients, especially when discussing complex or very unique flavours, one can expect to pay more. Basically, the cost of vape juice is also influenced by online deals, bundle offers, and loyalty discounts through which one could save a considerable amount.
Does E-Liquid Expire?
Yes, E-Liquids expire. Usually 1 to 2 years from the manufacturing date when stored properly. E-liquid manufacturers are required by law to have an expiration date on their e-liquid bottles. However, expiration dates on e-liquids are mostly guidelines set by the manufacturers.
It is almost similar to the best-before date of food product manufacturers. That is, e-liquid can be at its best in flavour and vapeability during this period. Over time, nicotine strength may degrade, and flavours can lose intensity. Exposure to heat, light, and air can speed up this process. Proper storage in a cool, dark place helps maintain the liquid’s quality. Sealed bottles last longer than opened ones, preserving flavour and nicotine content.
