For beginners, it’s best to start with a simple recipe or a one-shot concentrate. We’ll look at finding these in more detail below. Or if you have a great idea for a flavour combination, you can jump right in. But be sure to make detailed notes so you can tweak future versions.
1) Recipe And Ratios
The first step is to find a recipe you like the sound of, and buy the relevant concentrates. For this example, we’ll use the recipe for Mustard Milk, a popular strawberry milkshake flavour, created by reddit user and leading DIY e-juice maker Fizzmustard:
- Strawberry (TPA) 6%
- Vanilla Bean Ice Cream (TPA) 6%
(TPA is the abbreviation for The Perfumers Apprentice, a major flavour manufacturer. But when going to TPA, you want to use their products listed under the Flavor Apprentice for your DIY endeavors).
Now we need to decide what PG/VG ratio to use. Fizzmustard recommends VG/PG 70/30, which makes it suitable for sub ohm vaping. You could also try out max VG, or if you want a version that works in a plus-ohm tank try a higher ratio 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, choose your nicotine level. Here, we’ll make a 10 mL bottle of Mustard Milk with 6 mg nicotine and VG/PG at a 70/30 ratio, but you can adjust to your personal taste.
Now we have our choices we need to work out the amounts to use. This can be complicated to do by hand, but don’t worry, there are various online juice calculators that do it automatically. For best results, set up an account on eLR – it’s easy to use and you can access your recipes it from any online device. (Other more-comprehensive juice calculators such as EjuiceMeUp and Steam Engine are also recommended.) 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. Another good all-in-one calculator is at e-liquid-recipes.com. You’ll be able to save your e-liquid recipes as private or public (so other users can see it).
Time to get your hands dirty. First, and most importantly, set aside a safe hygienic area in a clean room with no pets or children around. Use rubber gloves and a plastic tray in case of spillage.
By Weight – If you’re using scales, you should focus on the grams. Put your empty 10 mL bottle on the scales and set it to zero. Now add your flavours by dripping in the correct amount in grams. Then add nicotine using a dropper or syringe and be careful not spill any. Use your squeezy bottles to add the PG and VG. If you prefer to use syringes, make sure you use a fresh one for each ingredient to avoid cross-contamination. The final weight should match that shown on eLR table.
By Volume – If you’re mixing by volume it’s a bit trickier. Using separate syringes for each component, check the measurements on the syringe to gauge the mL and add these to the empty 10 mL bottle. Each flavour concentrate and nicotine will require an individual 1 mL syringe. Be aware that this method is less accurate than using scales.
Note: Another way to use volume, and possibly the simplest (albeit maybe not the most easy to convey for others to replicate or to scale up) is by using drops as your measurements. It works really well with flavorings, and if you make a small investment in empty plastic dropper bottles (ideally with all the same size droppers) it should suit you fine. This is the least precise way of measuring for nicotine, so we caution against using drops to get your nic percentage bang-on.
Congratulation, you now you have your first homemade bottle of DIY e-juice! What now?
