Rainbow Flavours Concentrate Mixing Chart











**Based on 10ml Rainbow Flavours concentrate at 20% flavouring**
**Final bottle size: 50ml**
**Concentrate type: PG-based**

### 0mg Mix — No Nicotine Shot Added



| Desired VG/PG Ratio | Rainbow Flavours Concentrate | Add VG | Add PG | Final Mix |
| --- | --- | --- | --- | --- |
| **40VG / 60PG** | 10ml | 20ml | 20ml | 50ml |
| **50VG / 50PG** | 10ml | 25ml | 15ml | 50ml |
| **60VG / 40PG** | 10ml | 30ml | 10ml | 50ml |
| **70VG / 30PG** | 10ml | 35ml | 5ml | 50ml |
| **80VG / 20PG** | 10ml | 40ml | 0ml | 50ml |





---

## With 1 x 10ml Nicotine Shot Added

**Example based on a 10ml 18mg nic shot at 70VG / 30PG**
This would make a **50ml finished bottle at approx. 3.6mg nicotine strength**.



| Desired VG/PG Ratio | Rainbow Flavours Concentrate | Nic Shot | Add VG | Add PG | Final Mix |
| --- | --- | --- | --- | --- | --- |
| **40VG / 60PG** | 10ml | 10ml | 13ml | 17ml | 50ml |
| **50VG / 50PG** | 10ml | 10ml | 18ml | 12ml | 50ml |
| **60VG / 40PG** | 10ml | 10ml | 23ml | 7ml | 50ml |
| **70VG / 30PG** | 10ml | 10ml | 28ml | 2ml | 50ml |
| **80VG / 20PG** | 10ml | 10ml | 33ml | 0ml\* | 53ml\* |





\* An **80VG / 20PG mix is not possible as an exact 50ml mix** when using a 10ml PG-based concentrate plus a 70VG / 30PG nic shot, because the PG content is already too high. To get closer, use a **100VG nic shot** or reduce the final nicotine strength.

### Simple Mixing Rule

Your **10ml Rainbow Flavours concentrate already counts as 10ml PG**.

So when working out your mix:

**Final PG amount needed – 10ml concentrate PG – PG from nicotine shot = extra PG to add**

**Final VG amount needed – VG from nicotine shot = extra VG to add**

For best results, shake well and allow the mix to steep if needed, especially with dessert, cream, or complex flavours.
