100ml shortfill e liquids are now one of the most popular choices for vapers in the UK. They provide excellent value, huge flavour variety, and flexibility with nicotine strength. However, not all shortfills are the same, and knowing what to check before buying can help you avoid disappointment. From ingredients and ratios to flavour quality and value, this guide explains the key things you should consider before adding a 100ml bottle to your basket.
1. Flavour profile
The first thing most vapers think about is flavour. With 100ml bottles, you are committing to thousands of puffs of the same juice, so choosing the right flavour is essential. Popular options include fruits, desserts, candies, and sodas. Think about whether you want something sweet for all-day vaping or a bolder flavour that works best in shorter sessions.
If you are unsure, look at what other vapers are buying. Strawberry, blackcurrant, and menthol blends remain classics, while more adventurous flavours like strawberry soda or sweetshop-inspired laces are growing in popularity. You can browse our 100ml vape juice collection for inspiration across a wide range of categories.
2. VG/PG ratio
The VG/PG ratio affects both the flavour intensity and the way the juice works with your device. Most 100ml shortfills are high VG, often around 70VG/30PG. This ratio is designed for sub ohm devices that produce large clouds and deliver smoother vapour.
If you are using a smaller pod system or a device with higher-resistance coils, a high VG liquid may be too thick, causing dry hits or poor performance. Always match the juice ratio to your kit to ensure the best experience.
3. Nicotine flexibility
One of the main advantages of shortfills is the ability to customise nicotine strength. 100ml shortfills are usually sold in 120ml bottles, leaving space for two 10ml nic shots. Adding one nic shot gives you around 1.5mg of nicotine, while two shots give 3mg. If you prefer nicotine-free vaping, you can simply use the juice as it is.
Before buying, make sure you know how many shots you need and whether they are included with your shortfill. Many of our shortfills come with two free nic shots, saving you money and making the process easier.

4. Price and value
100ml shortfills are usually much cheaper per ml than smaller bottles or nic salts, but prices can still vary between brands. Always check what is included in the price. Some bottles cost around £10 and come with free nic shots, while others may charge extra for nicotine. Looking at cost per ml and puff count is the best way to judge value.
For example, a £10 100ml shortfill with nic shots gives around 10,000 puffs, which is far more affordable than buying multiple 10ml bottles or nic salts. If you are a regular vaper, this can save you a significant amount over time.
5. Brand reputation
Not all vape juice brands are created equal. Cheaper liquids may cut corners on flavour quality or use ingredients that burn coils faster. Look for brands with a good reputation for consistency and smooth flavour. Bestsellers like Slonk by Spartan Juice, Odyssey Black by Spartan Juice, and Kong Blood by Lucky Thirteen are trusted by vapers for delivering both value and taste.
Reading reviews can also help you decide whether a flavour is worth trying. A well-reviewed shortfill is usually a safer investment, especially when committing to a large 100ml bottle.
6. Bottle design
It might not seem important, but the design of the bottle can make a big difference. A good shortfill bottle should have a secure cap, a proper tamper seal, and a nozzle that makes filling your tank easy. Poorly designed bottles can leak or be difficult to open, which wastes juice and makes a mess.
Look for bottles with sturdy construction and easy-to-remove nozzles when you need to add nicotine shots.
7. Shelf life and storage
Before buying, check the best-before date on the bottle. While most e liquids last one to two years unopened, fresher stock will always taste better. Once opened, it is best to use the liquid within six months for maximum flavour quality. Store your bottles in a cool, dark place to protect them from heat and light, which can cause nicotine and flavourings to break down more quickly.
Final thoughts
Buying 100ml shortfill e liquids is one of the best ways to save money and enjoy more flavour variety, but it pays to know what to check first. Think carefully about the flavour you want, make sure the VG/PG ratio suits your device, and always factor in whether nic shots are included. Consider brand reputation, bottle quality, and shelf life to make sure you get the best possible experience.
With so many flavours available and unbeatable value compared to smaller bottles, 100ml shortfills are a smart choice for most vapers. By following this checklist, you can choose a bottle with confidence and enjoy every puff from start to finish.
