Mixing E-Liquids - How to Do It and What You Should Consider
This guide has been created to provide neutral, fact-based information about how to mix ready-made e-liquids. The purpose is to provide an understanding of what happens when flavors, nicotine strengths, and VG/PG ratios are combined.
What Does It Mean to Mix E-Liquids?
Mixing e-liquids means combining two or more ready-made liquids in order to adjust the flavor, nicotine content, or properties of the liquid. This can be done for several reasons, such as creating a unique flavor profile, softening a strong flavor, or adjusting the strength. The process is simple but requires an understanding of how proportions affect the final result.
Mixing E-Liquids for New Flavor Combinations
Flavor is often the main reason for mixing e-liquids. By combining different flavors, you can create something entirely new, but the result can sometimes be unexpected. Therefore, it is important to:
- Test small amounts: Start with 2–5 ml to determine whether the combination works before mixing larger volumes.
- Choose flavors that complement each other: For example, tobacco with caramel or vanilla, or fruity flavors such as berries and citrus.
- Allow the mixture to stabilize: After mixing, the flavors may need time (a few hours to a day) to harmonize.
How Nicotine Strength Is Affected When Mixing E-Liquids
When e-liquids with different nicotine strengths are mixed, the final strength will be an average based on the amount of each liquid.
Formula: (strength A × volume A + strength B × volume B) ÷ (volume A + volume B)
Example: If you mix 10 ml of 12 mg with 10 ml of 6 mg, you get: (12×10 + 6×10) ÷ 20 = 9 mg.
It is important to measure volumes accurately to achieve the correct strength, especially if you are trying to reach a specific nicotine content.
VG/PG Ratio When Mixing E-Liquids
VG (vegetable glycerin) and PG (propylene glycol) affect both vapor production and flavor intensity. When liquids with different VG/PG ratios are mixed, a new ratio is created that can change how the liquid performs in your e-cigarette.
Example: If you mix 10 ml of 50/50 with 10 ml of 70/30, you get approximately 60/40 as the final result.
- Higher VG: Produces a thicker liquid and may require coils with larger e-liquid flow openings.
- Higher PG: Produces a thinner liquid and more pronounced flavor, but may be more demanding on certain coils at high levels.
Compatibility with Your E-Cigarette and Coils
Not all e-liquids work optimally in all types of e-cigarettes. If the VG/PG ratio changes, this may affect how well the liquid is transported to the coil and how long the coil lasts. Always check:
- The VG/PG ratio recommended by the manufacturer of your device.
- Power settings – it is a good idea to start at a lower power and increase it gradually when testing a new mixture.
Storing Mixed E-Liquid
To maintain quality, mixed e-liquid should be stored in the same way as other e-liquids:
- In a clean, tightly sealed bottle.
- Away from direct sunlight and heat.
- Preferably labeled with the date, estimated nicotine strength, and VG/PG ratio.
Tips for the Best Results When Mixing
- Note the volumes, strengths, and VG/PG ratios so that you can recreate a mixture if you like it.
- Only mix small amounts during your first attempts to avoid wasting liquid.
- Always shake the bottle before use to ensure an even distribution of the contents.
Frequently Asked Questions About Mixing E-Liquids
Can you mix e-liquids from different brands?
Yes, you can, but the flavor and consistency may vary between manufacturers. Always start with small amounts to test compatibility.
Can you mix nicotine-free e-liquid with one that contains nicotine?
Yes. The final strength will be an average based on the volumes and original strengths, according to the formula above.
Is the shelf life affected when mixing?
Not necessarily, but the storage conditions should be the same as for the original liquid. Preferably use it before the stated best-before date.
Does the mixture need to rest?
In some cases, it may be beneficial to let the mixture stand for a while so that the flavors blend properly. Shake the bottle gently before use.
