How to Add Nic Shots to Shortfills Without Spillage - A UK Vaper’s Guide

Ever tried adding a nic shot and ended up with sticky fingers and half the bottle on the table? You’re not alone. Whether you’re a new vaper or a seasoned shortfill fan, mess-free mixing is something every UK vaper can master.

Here’s your quick and easy guide to topping up like a pro — no spills, no waste, just smooth nicotine integration and great flavour ahead.

Quick Recap: What Are Shortfills and Nic Shots?

Let’s keep it simple:

• Shortfill e-liquids are nicotine-free vape juices sold in underfilled bottles, leaving space to add nicotine shots. Popular with vapers using sub-ohm kits, shortfills typically have a high VG ratio for larger clouds and smoother hits. Shortfill bottles are 120ml, but contain only 100ml of liquid, allowing you to add one or two 10ml nic shots. Adding more than this is possible, but not recommended.
• 50/50 shortfills have a lower VG ratio, and they’re designed to be used with lower-wattage vape devices.
• Nic shots are small 10ml bottles of flavourless e-liquid containing concentrated nicotine. They are designed to be mixed with shortfill e-liquids to achieve your desired nicotine strength.

For example, adding one nic shot into a shortfill will give you a 1.5mg nicotine strength, and adding two shots will give you 3mg.

Get Set: What You’ll Need

Before the pour, wash your hands thoroughly with warm water to prevent contamination, and get your space and tools sorted:

• A flat, clean surface — cover it with paper towel to catch drips
• A pair of disposable gloves to keep things hygienic and protect your skin
• A small flathead tool or tweezers to lift those tight nozzles off shortfill bottles
• Your shortfill and nic shot of choice.

Always follow safety precautions when handling nicotine and e-liquids.

Step-by-Step: How to Add Nic Shots Without Spillage

Now that you’ve prepared your bottles and your workspace, you’re ready to start.

1. Pop the top

Unscrew the cap of your shortfill. Many bottles have child-proof caps, so you may need to push down firmly and apply some force while twisting to open. Carefully lift off the nozzle — some come off easily, while others might need a gentle nudge. It may be helpful to use a flat head screwdriver or other flat implement to carefully pry off the dropper cap.

2. Shake the nic shot

Give it a quick shake, then crack open the seal.

3. Pour slowly and steadily

Slowly squeeze the nic shot into the shortfill bottle for better control and to avoid spills. Don’t rush it — pouring too quickly increases the chance of overflow and air bubbles.

4. Seal and shake

Pop the nozzle (dropper cap) back on, screw the cap tight, and shake like you mean it — at least 60 seconds for even mixing. Thorough shaking is essential to achieve your desired nicotine strength.

After mixing, you’re ready to fill your vape device, and enjoy!

Spill-Free Mixing Tips

• Use a funnel – Especially handy if your nic shot bottle has a thick nozzle. Shortfill bottles are designed to make the mixing process a bit easier for users.
• Don’t overfill – That little space at the top? You need it for shaking. Shaking the bottle thoroughly is essential for even nicotine distribution.
• Keep tissues nearby – Just in case. Careful mixing and proper handling reduce the risk of spills and accidents.
• Store liquids in cool, dark places – This is simply to protect flavour and longevity.

What to Avoid

• Rushing – Quick pours = spills and wasted juice
• Poor coil compatibility – Make sure your nic shot has the same PG/VG ratio as your shortfill, paying attention to the propylene glycol content. Matching the PG/VG ratio, including propylene glycol, ensures your coils work properly and the vape experience is consistent.
• Incorrect base liquid – Using the correct base liquid is important for achieving the right consistency and even nicotine distribution in your final mix.
• Adding too much nicotine – Excessive nicotine can lead to a harsher vape, negatively affect the base liquid, and degrade overall flavour quality.
• Skipping the shake – It might look mixed, but uneven nicotine isn’t the vibe
• Touching nicotine – Always wear gloves when handling nic shots directly.

Troubleshooting: Fixing Common Mixing Mishaps

It might seem simple, but even the most careful vapers can run into a few bumps when mixing e-liquids. If your vape juice tastes off or the nicotine hit isn’t quite right, don’t worry — most issues are easy to fix. Remember that uneven nicotine distribution often happens if you don’t shake the bottle enough after adding your nicotine shots. Give your bottle a good, hard shake for at least a minute to make sure everything’s mixed.

If you notice leaks, check the cap and nozzle for any damage or poor fit. Sometimes, switching to a different bottle or replacing the cap can solve the problem. For flavour imbalances, double-check your ratios and make sure you’re not overpowering your e-liquid with too much nicotine or flavour concentrate. With a little attention to detail, you’ll quickly get back to a smooth, enjoyable vaping experience.
