Adding flavoring to your eLiquid

Flavor concentrates are made up of multiple components. Typically, flavors will consist of a dominant PG or VG base. Your Flavor Concentrates will be accounted for in either your PG or VG ratio depending on what base it is.

Step 1: Determine your desired Flavor Strength


Recommended flavor percentages for eLiquid and eJuice - Liquid Barn

Flavor Strength is the strength percentage you want the flavor in your finished eLiquid to be. Your percentage will vary based on the flavor and your personal preference. You will perfect this through trial and error. 


Step 2: Calculate the amount of flavor extract needed to add to your batch.


Simply multiply your desired percentage of flavoring by your batch size to find out the amount of flavor concentrate needed. 

Formula for calculating flavor for your eLiquid or eJuice - Liquid Barn

Use the formula for each additional flavor extract. It is recommended to keep the total percentage of all your flavors under 25%.

Keep in mind the more flavoring you add, the more complex your eLiquid becomes. We recommend starting off with single flavor recipes to familiarize yourself with different flavor profiles. You can then move on to more complex flavor recipes.

For this example we will be making a 30ml batch of eLiquid using a Flavor Strength of 10%. We will assume our Flavor concentrate is PG Based.


This means we will need 3ml of our Flavor Concentrate to reach a Flavor Strength of 10% in a 30ml batch of eLiquid. 

Since the 3ml of Flavoring is being counted towards our total PG ratio, we will now only need to use 12ml of Propylene Glycol to maintain our 50/50 ratio.



Our 30ml batch will consist of 50% PG and 50% VG. 15ml of PG Based Liquids and 15ml of VG Based Liquids.

We will need to mix together:
Flavor Concentrate: 3ml
Propylene Glycol: 12ml
Vegetable Glycerin: 15ml
