Part 2: The Mathematics of E-Liquid Mixing

Mixing your e-liquid involves a bit of Math. While it isn’t actually rocket science, you need to be familiar in scaling percentages of specific ingredients to craft the same quality of e-liquid on every batch, whether big or small.

E Liquid Mixing Math

There is a numbers game in e-juice making, and that’s what we will be talking about in this part of the tutorial. NUMBERS. If you are someone who doesn’t like talking about Math, don’t worry, It just sounds complicated but is fairly easy once you get acquainted with everything.

VG/PG Ratio in E-Liquids

The VG/PG ratio is important to take note of. Basically, their ratio determines if your e-liquid will produce more clouds and less flavor, or the other way around. A higher VG produces more clouds, but since it doesn’t hold flavor very well, you need PG for a better flavor profile.

Direct Vapor

An 80/20 VG/PG ratio has 80% of VG, and 20% of PG. This ratio is getting popular nowadays, with the sudden boom of the sub-ohm vaping culture. For beginners though, it is better to start off with a 60/40 ratio so you can get acquainted with flavors first. Once you get the hang of how much of each flavor concentrate is ideal, you can start experimenting with different VG/PG ratios.

E-Liquid Mixing Methods

There are a couple of ways to go about mixing; by mixing your e-liquid by volume, by weight, or both. Each method yields different results.

Here’s an example recipe that we will be using as an example for all methods:

  • 80% Vegetable Glycerin
  • 10% Propylene Glycol
  • 10% Flavor Concentrates

Mixing by Volume

If you want to go the easy way, mixing by volume would be the way to go. Following the recipe above, your recipe would be:

  • 80 mL vegetable glycerin
  • 10 mL propylene glycol
  • 10 mL flavor concentrates

Mixing by volume is popular because it is easier compared to the other methods and it requires less equipment. Also, mixing by weight for a batch as small as 5ml could be troublesome, so mixing by volume is the way to go.

One important thing about

Mixing by Weight

Mixing by weight involves mixing your e-liquid per batch of a specific weight.  Each one of your ingredients have different densities, so it’s best to check manufacturer specified gravity to keep your recipe consistent.

Basing on the recipe above, here’s what you will be putting to make 100 mL of e-liquid:

  • 100.9 g Vegetable Glycerin
  • 10 g Propylene Glycol
  • 10 g Flavor Concentrates

Mixing by weight by far is a more accurate method compared to mixing by volume.

As mentioned above, each ingredient of your e-liquid has a different specified gravity, so it’s better to take note of this so your mix is as accurate as possible.

Whatever method you would prefer to use, consistency is key. It would be better if you can give both of them a try to see what works better with you. In our own opinion though, mixing by weight is the better option.

Scaling Your Recipe

You might love that 10 mL batch that you made and would like to create a 1 Liter batch that you can start selling to your friends as a way to start your own vaping empire. You should be familiar with scaling percentages so your mix is consistent, regardless of the amount that you will make. I am fairly good with Math, but not really the best person to teach it to you. I just couldn’t find the words to explain how to do it. Good thing though, that recipe calculators like this one from e-liquid recipes exist.

You are acquainted with the numbers, but you still aren’t ready yet. There is no wax on wax off in DIY e-liquid mixing, but you have to be patient. The next part of this tutorial would be about safety precautions and hygiene.
