Mixing nic shots into a 100ml JustVape bottle is something many vapers do without thinking, but I have to be honest, doing it properly makes a huge difference to both safety and flavour. This article is written for everyday vapers who want a clear, practical and easy to follow guide to adding nic shots safely and effectively into shortfill bottles such as the 100ml JustVape range. Whether someone is completely new to shortfills or simply wants reassurance that they are doing things correctly, my aim is to explain the process in a straightforward way that feels natural and confident. In my experience a well mixed bottle produces far smoother flavour, more stable nicotine delivery and a much more enjoyable overall experience.
I have spoken to thousands of vapers over the years and one thing I have learned is that many people mix their bottles quickly without realising how important proper technique is. Small details like shaking thoroughly, adding the right amount of nic shots, maintaining hygiene and allowing the liquid to settle all affect the outcome. When you mix correctly you preserve flavour quality, protect your device coils and ensure your nicotine strength remains stable and predictable. What follows is a detailed and practical guide to mixing nic shots into a 100ml JustVape bottle safely and effectively, while also helping you understand why each step matters.
Understanding What a JustVape 100ml Shortfill Is
A 100ml JustVape bottle is a shortfill, meaning it contains 100ml of nicotine free e liquid inside a larger bottle with enough space to add nic shots. Shortfills exist because UK regulations limit nicotine containing bottles to smaller sizes. To create a bottle larger than these limits brands produce nicotine free liquid and leave room for the user to add their own nic shots at home.
Shortfills are designed to be easy to mix and the empty space inside the bottle is intentional. When used correctly this design allows vapers to customise their nicotine strength, maintain flavour quality and follow UK regulations safely.
In my opinion understanding the purpose of shortfills helps new users feel more confident about mixing. It is a simple process once you understand why the space is there and how the nicotine shots interact with the base liquid.
Why Nic Shots Are Added Separately
Nic shots are small bottles of nicotine base liquid designed to be added to shortfills. They allow users to choose their preferred strength while complying with UK limits on nicotine bottle sizes. The shots usually contain unflavoured nicotine diluted in a VG or balanced VG and PG mixture.
Adding nic shots separately ensures that the final mixture is both customisable and safe. Because the shots are flavourless they do not alter the taste of the JustVape liquid unless mixed incorrectly. When done well the flavour remains pure, clean and exactly as intended by the manufacturer.
In my experience using the right number of shots and mixing them correctly ensures consistency across each refill and prevents issues such as weak flavour, nicotine separation or uneven delivery.
How Many Nic Shots You Need for a 100ml Bottle
A 100ml shortfill is intentionally designed to be mixed with specific amounts of nic shots. The number of shots determines the final nicotine strength. While I cannot use numbers in this article, I can say that most 100ml bottles have enough space left in the bottle for the amount of nic shots needed to reach the most common strengths among everyday vapers.
In my opinion it is always best to follow the manufacturer’s guidance for the correct number of nic shots. This keeps your final mixture balanced, ensures your nicotine strength is accurate and maintains the intended flavour quality.
Why Using the Correct Nic Shots Matters
Nic shots come in different VG and PG ratios and using the wrong one can alter the consistency of your liquid. JustVape liquids have a specific balance designed for smooth flavour and stable wicking. If you use a nic shot that is far thicker or thinner than the base liquid you may affect how well your coils absorb the mixture.
Nic shots designed for shortfills usually match the consistency of the base liquid, which means the blended mixture maintains its intended thickness and flavour delivery. Using the correct type of shot ensures that the liquid remains compatible with your device and maintains proper wicking behaviour.
In my opinion beginners sometimes underestimate the importance of choosing the right shot. Using a shot that matches the liquid ensures smoother performance and helps avoid coil flooding or dry hits.
How to Prepare Your Bottle Before Mixing
Before adding nic shots it is important to prepare your bottle correctly. Make sure the cap is removed carefully and the nozzle is taken off without forcing it. Many vapers rush this part but taking your time helps avoid spills and keeps everything clean.
I always tell people to shake their nic shots before adding them because nicotine base liquid sometimes settles. This ensures your shot is evenly mixed before it goes into your JustVape bottle. It helps create a stable final mixture and prevents uneven nicotine distribution.
Hygiene matters as well. Clean surfaces and dry hands prevent contamination and ensure your bottle stays fresh. In my experience this small preparation step makes the entire process smoother and safer.
Adding the Nic Shots Safely
Adding nic shots is simple but should be done with care. Squeeze gently, avoiding sudden pressure that could cause liquid to spill or splash. Nicotine, even at lower strengths, should be handled respectfully. Keeping your skin clean and dry helps avoid irritation and ensures you maintain safe mixing conditions.
Once all your nic shots are added, replace the nozzle firmly and secure the cap. This prevents leaks while you shake the mixture. A loose cap is one of the most common causes of accidental spills, and I have seen many users lose part of their fresh mixture because they forgot to screw the top back on securely.
In my opinion this moment is also a good time to check the bottle for structural integrity. If the nozzle or cap feels loose, replace them or tighten carefully before shaking.
Why Shaking Is Essential for Even Mixing
Shaking is the step many vapers underestimate, but it is absolutely critical. Nicotine needs to blend fully with the base liquid to create a consistent vape. If the bottle is not shaken enough the nicotine may remain unevenly distributed, which affects flavour, performance and satisfaction.
Shaking introduces movement that blends the liquids thoroughly. I always recommend shaking the bottle for longer than you think is necessary because the viscosity of the liquid can slow down blending.
The aim is to ensure every refill from the bottle contains the same amount of nicotine. A well shaken bottle produces stable results, and in my opinion this is one of the most important habits for everyday vapers mixing shortfills.
Letting the Liquid Settle for Best Results
After shaking, allowing your bottle to settle gives the ingredients time to combine naturally. This helps the flavour stabilise and ensures the nicotine fully integrates with the base liquid.
Some users like to leave the bottle for a while after mixing to allow the flavours to bloom more naturally. Shortfills often taste their best once the mixture has had time to rest. The settling period also allows any air bubbles introduced during shaking to rise and disperse, which makes the liquid smoother to pour.
In my experience this settling time leads to a richer, more consistent flavour profile and reduces the likelihood of early coil flooding.
Why Proper Mixing Protects Coil Lifespan
Coils are sensitive to the consistency of your liquid. If nic shots are not mixed properly the liquid may be uneven, thicker in some areas or thinner in others. This imbalance can cause wicking issues, harsh hits or flavour changes.
When your liquid is mixed well, the viscosity remains stable which supports even coil saturation. This prolongs coil life and helps you avoid unpleasant dry hits or premature burning. Consistent liquid texture is essential for smooth vaping, especially in pod systems.
I have seen many users blame their device or coil for problems that came from poorly mixed shortfills. Proper mixing protects your hardware and improves the lifespan of your consumable components.
Understanding How Flavour Changes After Mixing
Flavour can change slightly after adding nic shots because you dilute the base liquid. Well formulated JustVape shortfills are designed to maintain strong flavour even after mixing, but some subtle changes are natural.
Many users find that their flavour becomes smoother and more rounded after the nic shot settles into the blend. In my opinion this is part of the charm of using shortfills. You can experience the flavour as it develops and enjoy its stability once the liquid reaches full maturity.
If you find the flavour too light after mixing, shaking again or giving the liquid more time often makes a noticeable improvement.
Why Accurate Nicotine Levels Depend on Proper Blending
Accurate nicotine strength is essential for maintaining a satisfying vaping routine. If the bottle is not shaken thoroughly, some refills may contain more nicotine than others which creates inconsistent hits.
This inconsistency can make you vape more or less frequently than usual, which disrupts your routine. Proper mixing ensures that each millilitre of liquid contains the same amount of nicotine so your experience remains stable.
In my experience this consistency is essential for people switching from smoking because it helps regulate cravings and maintain progress.
Tips for Avoiding Common Mixing Mistakes
Several common mistakes occur when mixing nic shots. Opening the bottle too forcefully can cause spills. Forgetting to shake can create uneven nicotine distribution. Adding the wrong type of nic shot can alter the liquid thickness.
Taking your time during each step prevents mistakes. Using the right nic shots, shaking thoroughly, checking that the cap is secure and allowing the liquid to settle all contribute to a smooth and predictable outcome.
In my opinion patience is your best tool here. Mixing shortfills should feel calm and controlled, not rushed.
How to Store Your Mixed Bottle Correctly
Once your bottle is mixed and ready, storing it correctly helps maintain flavour quality and nicotine stability. Keeping the bottle upright, away from heat and out of direct sunlight preserves the integrity of the liquid.
Shortfills store extremely well when kept in normal indoor conditions. Avoid storing them in very warm or cold areas because temperature fluctuations can affect liquid consistency.
In my experience proper storage keeps your flavour tasting clean and prevents the liquid from thinning or thickening unexpectedly.
Why Good Mixing Habits Improve the Overall Vaping Experience
Good mixing habits create a smoother, more predictable and more satisfying vaping experience. They ensure that your nicotine strength remains consistent, your flavour stays pure and your coils perform reliably.
Many people do not realise how much proper mixing contributes to the quality of their daily vape. When done correctly the bottle becomes a stable source of liquid that supports your routine for days or weeks. In my opinion learning to mix well is one of the most valuable skills for everyday vapers.
A Personal Reflection on Mixing Nic Shots
After helping countless vapers learn how to mix their shortfills over the years I can confidently say that safety, patience and technique make all the difference. A well mixed bottle elevates your experience, protects your coils and helps maintain nicotine consistency. Once you become comfortable with the process it feels natural and even satisfying to prepare your bottle.
I have always believed that mixing nic shots gives vapers a sense of control over their experience and helps them take ownership of their routine.
