The vaping community has a culture of individuality and personalisation. Whether you are new to vaping or are a veteran, one of the few drawbacks you might’ve noticed is the cost of e-juice. These costs can burn a hole in your pocket quickly, especially if you are a fan of premium brands like Cosmic Fog. There’s a solution: make your own e-liquid. DIY e-juice is now a growing hobby among vapers, as it is just as good as a shop-bought item at a fraction of the cost. You can also control the nicotine level to your satisfaction.

What is DIY E-Juice?

DIY e-juice mainly involves making your own e-liquid by mixing 4 main components. These are VG, PG, flavouring and nicotine. You don’t need a degree in chemistry, its a pretty simple process if done carefully.

Components Needed

You’ll need to get the four elements that makeup e-juice.

  • PG (Propylene Glycol): You’ll need a bottle of this with no additives, around 500ml or 1L for starters.

  • VG (Vegetable Glycerine): It makes up the bulk of e-juice. Buy a litre of pharmaceutical grade.

  • Nicotine: Nicotine degrades rapidly when exposed to air, so it’s important to get some that are of good quality. Make sure to keep it sealed too. It must be handled very carefully as undiluted nicotine is poisonous. If even a little spill onto your skin you can get very sick, very quickly.

  • Flavor Concentrates: What your e-juice tastes like is dependent upon these. You can blend thousands of individual flavors in any number of permutations and combinations.

After getting the liquids, you will need equipment for the actual mixing process. You can mix by volume or by weight, whichever you prefer.

  • Scales: If mixing by weight gets a small set of scales that go up to 0.01g for extra accuracy.

  • Storage Bottle: Store the PG and VG in squeezy bottles for easier addition to the bottles. Store your nicotine in a bottle with a dropper.

  • Syringes: If mixing by volume, you’re going to need a selection of syringes. Get 10ml syringes for PG and VG, and a lot of 1ml syringed for the nicotine and flavour concentrates.


Recipe and Ratios

Firstly, find a flavour you like the sound of or would like to try out and buy the relevant concentrates. Then, we need to decide what PG/VG ratio to use. A VG/PG ratio of 70/30 is recommended. If you want to try a higher proportion of PG such as 50/50. If you change the VG/PG ratio you might need to adjust the amount of flavour added to get a similar taste. Next thing to do is choosing your nicotine level. You can adjust this to your taste.


You can use websites like to work out the amounts to use. This can be complicated to do by hand. Just go to the create recipe page, input the relevant details and hit save. This will produce a table showing the volume, weight and percentage of each ingredient. The rest of the steps are explained in detail. You can also choose to keep your recipe private or public if you want to share it with everyone.
