It’s not complicated to DIY your own e-juice flavor as you think. All you need to prepare are three things: e-liquid ingredients, DIY tools and e-liquid calculators.

E-Liquid DIY

E liquid ingredients:
  • Nicotine
  • PG/VG
  • Flavor
  • Distilled Water
  • Vodka

Nicotine strength, PG/VG and flavors can be adjusted according to your taste. You can also mix PG/VG and flavors without nicotine, water and vodka.

Nicotine strength:
The mg(milligram) of nicotine = amount of nicotine per ml(milliliter)
Here are some nicotine levels for you to customize your target level.
  • Low level: 0mg - 10mg
  • Medium level: 11mg - 16mg
  • High level: 17mg - 24mg
  • Extra level: 25mg - 36mg
PG gives stronger throat hit of e liquid.
VG is smoother but produce more vapor.
Flavor: The amount of flavors in e juice mixture are largely depending on equipment type, flavor strength and personal habit. Generally you will need 5% to 20% flavors. We recommend to start from low level of e liquid flavor in small amount and add more until you get your favorite taste.

DIY e liquid tools
There are some tools you need to mix e juice:
  • Measuring cup
  • Funnel
  • Empty bottles
  • Pipet and gloves
  • Index card
  • E-liquid calculator
E-liquid calculator
Many versions of e liquid calculators can be found online. The measure tool is required to help you get the right nicotine level. For example:
Given that you have unflavored Nicotine Liquid that is 36mg 50%PG 50%VG, and you target level is 10ml of e liquid with 16mg of nicotine level and 15% flavor.
You need to mix:
1.5ml of flavor
4ml 50% PG or VG (2ml of PG and 2ml of VG)
4.4ml of 36mg unflavored Nicotine Liquid 50%PG 50%VG
You can measure e liquid ingredients by accounting drops or measure cups. Latex gloves are recommended to hold high concentration nicotine solution. Then shake the mixture in bottles and start to enjoy vaping.
