AuNic Salt Nicotine Shot (VG) 15ml: How to Use It in a Shortfill
Squeeze the entire 15ml AuNic Salt Nicotine Shot into your 80ml shortfill bottle, put the cap back on, shake for 30 seconds, and wait 5 to 10 minutes before vaping. The result is a 100ml bottle of e-liquid at your target nicotine strength — ready to use with no measuring required.
What Is a VG Salt Nicotine Shot?
A nicotine shot (also called a nic shot) is a small bottle of unflavoured nicotine liquid designed to be added to a nicotine-free shortfill e-liquid. It contains no flavour — just nicotine, a carrier base, and nothing else.
The AuNic Salt Nicotine Shot is:
- Salt nicotine — a smoother form of nicotine that absorbs faster and hits less harshly than freebase, even at higher strengths
- VG-based — vegetable glycerin as the carrier, which blends well with high-VG shortfills and produces denser vapour
- 15ml — the standard shot size designed to fill the 20ml gap in an 80ml shortfill bottle
Together, the shortfill and the nic shot combine to make a full 100ml bottle at your chosen nicotine level.
What You Need Before You Start
- One 80ml shortfill e-liquid (in a 100ml PET bottle with 20ml of empty space)
- One or two AuNic Salt Nicotine Shot (VG) 15ml bottles depending on your target strength
- Clean hands
- 5 to 10 minutes of patience for the nicotine to blend fully
That is it. No syringes, no scales, no mixing equipment needed.
How to Calculate Your Nicotine Strength
The AuNic Salt Nicotine Shot contains nicotine at a set concentration. When added to an 80ml shortfill, the final strength depends on how many shots you add.
| Shortfill Size | Nic Shots Added | Final Bottle Size | Approx. Final Strength |
|---|---|---|---|
| 80ml | 1 x 15ml shot | 95ml | ~3mg |
| 80ml | 2 x 15ml shots | 110ml (slight overfill) | ~6mg |
| 60ml | 1 x 15ml shot | 75ml | ~4mg |
Most vapers add one 15ml shot to an 80ml shortfill. This gives a nicotine level suitable for sub-ohm and direct-lung vaping. If you prefer a stronger hit — for example if you are coming from cigarettes or using an MTL device — two shots gives a noticeably stronger result, though the bottle will be slightly overfull.
Step-by-Step: How to Add the AuNic Nic Shot to a Shortfill
Step 1 — Remove the cap and nozzle from the shortfill bottle
Most 100ml PET shortfill bottles have a child-resistant cap with a separate inner nozzle. Unscrew the cap, then pull out the nozzle insert if there is one. Set both aside — you will need them at the end.
Step 2 — Open the AuNic Salt Nicotine Shot
Unscrew or puncture the cap on the 15ml nic shot bottle. Some nic shot bottles have a sealed nozzle that needs a pin or the bottle's own cap spike to open — check the cap before squeezing.
Step 3 — Squeeze the nic shot into the shortfill bottle
Hold the shortfill bottle upright. Insert the nozzle of the nic shot into the opening and squeeze the entire contents in slowly. There is no need to measure — the 15ml shot and the 80ml shortfill are designed to work together. The liquid level will rise but should remain below the bottle neck.
Step 4 — Replace the nozzle and cap
Reinsert the inner nozzle into the shortfill bottle, then screw the child-resistant cap back on firmly. Make sure it is sealed before shaking.
Step 5 — Shake for 30 seconds
Hold the bottle firmly and shake vigorously for at least 30 seconds. This distributes the nicotine evenly through the e-liquid. Without shaking, the nicotine will sit in layers and the strength of each puff will be inconsistent.
Step 6 — Wait 5 to 10 minutes before vaping
This is the step most people skip and should not. The VG carrier in the AuNic shot needs a few minutes to fully integrate with the shortfill base. Vaping immediately after mixing can result in a slightly harsh or uneven first few puffs. Set the bottle aside, fill your tank or pod, and vape after the short wait.
Why Use a VG-Based Nic Shot Specifically?
Most shortfill e-liquids are already high-VG — typically 70% VG or higher. Adding a PG-based nic shot to a high-VG shortfill changes the VG/PG ratio of the final liquid, which can thin the e-liquid, reduce vapour production, and alter the flavour slightly.
The AuNic Salt Nicotine Shot (VG) keeps the base consistent. If your shortfill is 80% VG, your finished bottle stays close to that ratio after adding the VG nic shot — same viscosity, same vapour production, same coil performance.
This matters most for:
- Sub-ohm tanks that perform best with thick, high-VG e-liquid
- Vapers who have dialled in a specific coil for a high-VG mix and do not want to change it
- Anyone sensitive to PG who prefers to minimise it in their e-liquid
If your shortfill is lower-VG or MTL-oriented, a PG-based nic shot may actually be the better fit. The AuNic range covers both — the VG shot for high-VG shortfills and the PG shot for thinner, MTL-style liquids.
Salt Nicotine vs Freebase: Which Shot Should You Use?
| Salt Nicotine Shot | Freebase Nicotine Shot | |
|---|---|---|
| Throat hit | Smooth, even at higher strengths | Stronger, more noticeable |
| Absorption speed | Faster | Slower |
| Best for | Pod systems, MTL, low-wattage devices | Sub-ohm, high-wattage, DTL vaping |
| Nicotine satisfaction | High at lower puff count | Requires more puffs for same effect |
The AuNic Salt Nicotine Shot suits vapers using pod systems and MTL setups — devices that vape at lower wattages where salt nic performs best. If you are using a high-powered sub-ohm tank, the AuNic Freebase Nicotine Shot is the better choice.
Common Mistakes to Avoid
Not shaking enough. Nicotine is denser than VG and will sink if not mixed thoroughly. Always shake for a full 30 seconds and give the bottle another quick shake before each fill.
Adding the shot to a full bottle. Shortfills are sold at 80ml in a 100ml bottle specifically to leave room for a nic shot. If someone has topped up a shortfill bottle to the brim, there will not be enough space for the shot. Always add the nic shot before filling your tank.
Using the wrong shot for your device. Salt nic at high wattage can produce an uncomfortably harsh hit. Match the shot type to your device — salt for pods and MTL, freebase for sub-ohm.
Skipping the wait time. Especially with VG-based shots, the thicker carrier needs time to bind with the shortfill base. Five to ten minutes makes a measurable difference in consistency.
Frequently Asked Questions
How much nicotine is in the AuNic Salt Nicotine Shot (VG) 15ml? The AuNic nic shot is formulated at a set concentration — check the label for the exact mg/ml figure. When added to an 80ml shortfill, one 15ml shot produces a final strength of approximately 3mg in a 95ml bottle.
Can I add half a nic shot for a lower strength? Yes. If you want a very low nicotine result, you can add half the bottle (approximately 7.5ml) and leave the rest sealed for next time. Use the cap to reseal the nic shot bottle between uses. Results will be approximately 1.5mg in the final blend.
Does it matter which shortfill brand I use with AuNic shots? No. The AuNic Salt Nicotine Shot is unflavoured and works with any shortfill e-liquid brand. The VG base blends cleanly without affecting the flavour profile of the shortfill.
How long does the mixed bottle last before it goes off? A mixed shortfill with added nicotine is best used within six months. Store it in a cool, dark place — a cupboard or drawer away from sunlight. Nicotine oxidises over time and exposure to light and heat speeds that process up.
Final Verdict
Adding the AuNic Salt Nicotine Shot (VG) 15ml to a shortfill takes under two minutes and requires no equipment beyond the two bottles. The VG base keeps your e-liquid ratio consistent, the salt nicotine delivers a smooth hit at any strength, and the 15ml format is sized exactly for a standard 80ml shortfill. Follow the six steps above and you will have a perfectly mixed 100ml bottle every time.
