Mixing your own Liquid is easier than it sounds: you need a base (nicotine-free Liquid or base), a nicotine shot if required, and the right calculation. The quick formula for nicotine strength: shot strength multiplied by the number of shots, divided by the total volume. A 10 ml shot at 20 mg/ml added to 30 ml of nicotine-free Liquid results in 5 mg/ml. In this guide, you’ll find mixing tables for all standard strengths, the right ratios for your device, and an honest assessment of when it’s worth mixing and when ready-made Liquids is the better choice.
What do you need to mix Liquid?
- The basics: A nicotine-free Liquid (0 mg) in a bottle, or a neutral base consisting of PG (propylene glycol) and VG (vegetable glycerine). Important: Mix using bottled Liquid, not Pods or disposable Vapes.
- Nicotine shot: A 10-ml vial containing 20 mg/ml, which is the legal upper limit in Switzerland. We offer it as Liquid Station Nicotine Shot available.
- Accessories: An empty bottle with a scale or a syringe for measuring, plus disposable gloves for handling nicotine.
PG/VG explained: Which ratio for which appliance?
PG delivers the flavour and provides the throat hit, whilst VG makes the vapour dense and the draw smooth. The ratio must be suited to the device:
| Ratio (VG/PG) | Suitable for | Features |
|---|---|---|
| 50/50 | Pod systems, MTL devices | Well-balanced, clean flavour, for tight coils |
| 70/30 | Sub-ohm devices (DTL) | Plenty of steam, smooth ride, needs more power |
| Max VG | Cloud devices | Maximum vapour density, minimal throat hit |
A Liquid that is too thick in a tight Pod coil will cause scorching, whilst one that is too thin in a sub-ohm tank will cause leaking. If in doubt, remember: a Pod system means a 50/50 mix.
The Nicotine Mixing Table
This is how much nicotine-free Liquid you’ll need for a 10 ml shot at 20 mg/ml to reach your target strength:
| Target strength | Nicotine-free Liquid | + Shots (20 mg, 10 ml) | Total quantity |
|---|---|---|---|
| 10 mg/ml | 10 ml | 1 shot | 20 ml |
| 6.7 mg/ml | 20 ml | 1 shot | 30 ml |
| 5 mg/ml | 30 ml | 1 shot | 40 ml |
| 4 mg/ml | 40 ml | 1 shot | 50 ml |
| 2 mg/ml | 90 ml | 1 shot | 100 ml |
The formula behind this, in case your quantities differ: nicotine strength = (shot strength × shot millilitres) ÷ total millilitres. You can use this to work out any combination yourself in seconds.
Step by step: How to mix it properly
- 1. Measuring: Add Basis-Liquid and the shot to the bottle as shown in the table. Wear gloves; nicotine should not come into contact with the skin.
- 2. Shaking: Close the bottle and shake it vigorously for one to two minutes to ensure the nicotine is evenly distributed.
- 3. Leave it to rest: Leave it for a day, and the mixture will be uniform. For flavour blends made from scratch: leave to mature for a few days to two weeks.
- 4. Labelling: Strength and date on the bottle. Store out of the reach of children and away from light.
When is it worth mixing, and when should you use ready-made Liquid?
Mixing is worth it if you want a strength that isn’t available ready-made (such as 5 mg/ml), or if you need larger quantities and want to save money per millilitre. Ready-made Liquids is the better choice if you want it done quickly and without having to do any calculations: Our Liquids in 10 ml at 10 or 20 mg/ml We stock the standard strengths, ready-mixed. We do not currently stock a nicotine-free 0 mg base in bottles; you’ll need to purchase this from a specialist retailer for diluting.

Safety: It’s all part of it
Nicotine is a neurotoxin and must be handled with care: wear gloves when mixing, always secure bottles with child-resistant caps, and store them out of the reach of children and pets. Wash off any spilled nicotine with plenty of water. And, of course, the same applies when mixing your own: nicotine products should only be handled by those aged 18 and over.
Conclusion
Using a nicotine shot, nicotine-free Liquid and the table in this guide, you can mix any strength yourself in two minutes – it’s cheaper than buying ready-made and tailored exactly to your needs. If you don’t want to do the maths, just go for the ready-made Liquids: The Nicotine shot and you can find all our ready-mixed starches in our Liquid range.
Frequently asked questions about mixing Liquid
What mixing ratio does my e-cigarette require?
Pod systems and MTL devices work best with a 50/50 (VG/PG) mix. Sub-ohm devices that produce a lot of vapour can handle a 70/30 mix. If in doubt, check the recommendations in your device’s manual.
How do I work out the nicotine strength when mixing?
The formula: (shot strength × number of shots) divided by the total volume. A 10 ml shot at 20 mg/ml diluted to 30 ml of nicotine-free Liquid yields 200 mg in 40 ml, i.e. 5 mg/ml.
How long does home-mixed Liquid need to cure?
When mixing ready-made Liquid with a shot, a vigorous shake and a day’s waiting time are sufficient. If you’re mixing from scratch using flavourings and a base, allow it to mature for a few days to two weeks, depending on the flavouring.
Is it permitted to mix Liquid yourself in Switzerland?
Yes, for personal use. For nicotine-containing Liquids, the upper limit is 20 mg/ml, and it is only available to those aged 18 and over. When handling nicotine, gloves must be worn and it must be stored out of the reach of children.
Is it worth it in terms of price?
Yes, definitely. Bulk packs of nicotine-free Liquid plus shots cost a fraction of the price per millilitre compared to ready-made 10-ml vials. It just takes a bit of patience and care.
Warning: This product is harmful to your health and is highly addictive. Only available to persons aged 18 and over.
