So you have purchased your electronic cigarette starter kit and are eager to mix up your first flavour.

In general, with The Flavor Apprentice concentrates, you can use between 5 and 20% of the total volume you are creating, so as an example, let’s say we are going to make 10ml, then the maximum volume of concentrate at 20% would be 2ml, 10% at 1ml, and so on.

The rest of the e-liquid is mixed using one or more of the following, Propylene Glycol (PG), Vegetable Glycerine (VG), and/or Nicotine Liquid. Depending on the strength of your nicotine will determine how much of your nicotine liquid you will need to use. For example, if your nicotine has a strength of 24mg and you vape a strength of 12mg, then you would need to add 5ml of your nicotine. If you had 100mg/ml nicotine, and you vape a 12mg, then the total nicotine liquid you would need is 1.2ml.

So as you can see, the stronger the nicotine strength per ml, the less you need. However, there are increased toxicity levels when you get to, and above 100mg/ml in strength.

Handling nicotine at 100mg/ml requires Personal Protective Equipment (PPE), such as protective gloves, breathing mask, and something to place on the table you are working at to prevent damage to furniture. I also recommend whenever you work with nicotine, you wear a long sleeve shirt to protect you from splash-backs.

As much as nicotine at 100mg/ml is highly toxic, if consumed or it comes in contact with your skin and you do not wash it off in a reasonable time, it is still relatively safe if you use your head and don’t be silly with it.

Nicotine is a toxic chemical when used at high mg strengths and in large volumes, however, we can’t confuse danger with bad for you, see the following post for more information on how nicotine might be good for us. Nicotine Health Benefits?

So now you understand the seriousness of handling nicotine and how, if used sensibly, it will be a perfect alternate to smoking cigarettes and will save you thousands of dollars each year, and if you are a couple, it can save you more than $10,000 per year given the price of cigarettes today.

OK, lets start mixing our first e-liquid.

In our starter kit we ordered 5ml of Strawberry and 5ml of Custard. The idea is to order 2 complimenting flavours. In this example, strawberries and custard actually might taste nice, so we ordered these 2.

For this first flavour, we will use 12% strawberry and create a 12mg e-liquid using 24mg/ml nicotine, and another one using 100mg/ml nicotine.

Strawberry Recipe Using 24mg/ml Nicotine

  • Strawberry Concentrate – 12%
  • Using a 50% VG and 50% PG
  • 12mg vape, reduced from 24mg/ml nicotine

Strawberry Recipe Using 100mg/ml Nicotine

  • Strawberry Concentrate – 12%
  • Using a 70% VG and 30% PG
  • 12mg vape, reduced from 100mg/ml nicotine

First thing we do is put the lighter and lesser volume ingredients in first, so for example, in 90% of all cases you will put the flavour concentrate in first, then generally the nicotine, with PG and VG being the last 2 ingredients in all cases.

The reason we place the lesser volume and lighter ingredients in first, is because they will mix easier if they are at the bottom of the heavier and larger liquids.

So head over to the e-liquid calculator and enter the following values for the first recipe. Be sure to click on the image to get a larger view.


Once you have entered all the data into the calculator, click on the Calculate button and the results returned will be your e-liquid recipe.


The only column we are interested in is the one titled ‘ml’. Based on the figures we have provided, the calculator has worked out all the math for us and all we need to do is add the volume under ml for the ingredient displayed on the left of this value.

That is how easy it is, now lets look at what the ml volumes would be with the second recipe to give a comparison.


Again with the stronger nicotine, the same results page will be returned with all the required volume amounts for each ingredient.


As you can see, the  values in each recipe are different, except for the Strawberry concentrate and the PG/VG ratios, this is because we have told the calculator we want 12% of the total end volume, the value entered in the ‘Amount to Make’ box, and we want a 70% VG and 30% PG base.

Once you have added all your ingredients, it’s time to put the cap back on the bottle and give it a good vigorous shake for about 30 to 60 seconds. After that, you will want to let it stand for a few hours and then shake the bottle again and test vape.

Ultimately, you will want to let your juices age for at a minimum of 3 days for best results in taste. Personally, I leave many of my juices to age over a number of weeks to months.

The longer you leave it, the better it becomes.

To age your juice, you will want to open the bottle up every few days to allow fresh oxygen to enter the bottle, this is a process that helps oxidise the e-liquid. When you put the cap back on, give it a good shake again
