Step 1. Prepare Nicotine
Here you’ll need some math skills to figure out the volume of nicotine required for the e-liquid to achieve the desired percentage. Since you’ll have diluted nicotine, use its strength in milligrams and the overall volume of the e-juice to calculate the required amount of nicotine. You can also use an online e-juice calculator or smartphone app to make life easy.
Adding too much nicotine can be a mess up so add a little less than the amount recommended by your e-juice calculator or the e-juice recipe, then add to the mix according to taste after steeping.
If the nicotine level is enough for you, but you still want more throat hits, adding a few drops of vodka will help. It doesn’t take much; about one to five percent will be good enough.
Step 2. Prepare Flavor(S)
This is where your skills and luck come in, especially if you want to make a new flavor. Also, this step can make or break the e-juice and deserves your maximum consideration. You can either use one flavor or combine several different flavors. However, for beginners, we recommend starting with just one or two flavors and then go from there.
Trial and error is the only approach to making e liquids, but as a rule of thumb, add a little less flavor than what the e-juice calculator or the recipe recommends. It’s better to start with less flavor than to ruin the entire batch by adding too much.
After steeping, do a taste test and add flavoring according to taste. Unless you’re sure what you’re doing, never add more flavoring agents than 10% of the total volume of the end product.
Also, artificial flavors are extremely complicated and can behave differently when used with other flavors or chemicals.
For instance, if you added a recommended amount of flavor to your e-liquid but don’t feel anything, adding too much flavoring will usually not help, or might even backfire by washing out the flavor. It becomes even more complicated when you’re mixing flavorings, as the final flavor can be totally different from what you expected.
Step 3. Prepare Base
You can choose any VG/PG blend depending on your recipe, but usually, it’s between 50/50 and 80/20. Just remember that diluted nicotine usually contains some levels of PG or VG, so don’t forget to take that volume into consideration.
Step 4. Mix the Blend
When you’ve everything ready, mix it in a bottle and shake it, and I mean shake the heck out of it as most e-juices (especially high VG e-juices) are very thick, and need some shaking to blend the ingredients properly.
Step 5. Steep
To steep it or not is a personal preference. Most e-juices will taste much better when steeped, just like good, aged wine. You can try out your freshly made e-liquid after you’ve experimented with how to make DIY vape juice. If it tastes really good and is up to your expectations, you might want to skip this step.
Basically nothing but oxidation of the components of your juice, steeping is a process in which you leave the ready-to-vape e-juice sit for a while in a cool, dark place. There is no predefined period as to how long the juice should be steeped, but it can take a few days or even several months. Again the denser components will finally settle down at the bottom, so you’ll need to shake them every once in a while.
Ideally, you should leave the cap off and let oxygen play its trick and make the highly volatile fluids, such as alcohol vaporize into the air. Some people sporadically put the bottles in warm water, which can actually speed up the steeping process.
Another technique involves using a coffee mug warmer or a slow cooker, which can steep the fluids in days instead of weeks. However, in this case, you’ll need to frequently check the water level.
After steeping, not only the flavor but also the color of the juice will change because of nicotine getting oxidized. Instead of a colorless or light pale-ish color, you might see a more alluring, yellowish, or even light brown color.
In fact, a color change is a sign of your juice being properly steeped. When it comes to steeping there is nothing absolute. For better steeping, you need two things: patience and experimentation. The process is long and monotonous, but the outcome is worth the wait.
