If you’re just starting to mix your own vape juice at home, you’re in for a fun (and money-saving) ride. But let’s be real—DIY isn’t something to rush into without knowing the basics. Below is a straightforward, no-fluff guide based on what actually works for most people. I’ve reorganized everything into clear steps so you can follow along easily and avoid the common headaches.
Safety Comes First—Don’t Skip This
Mixing e-liquid involves chemicals that demand respect. Here’s what every beginner needs to keep in mind:
Never use pure, high-concentration nicotine. Stick with a 36 mg/ml nicotine base—it’s strong enough to get the job done safely and easy to calculate with any online mixer.
Wear gloves and eye protection. Keep the liquids away from your mouth, eyes, and skin. If anything spills, wash it off immediately.
Store all raw ingredients (especially nicotine) in a locked cabinet, far from kids, pets, and any open flames or heat sources.
Only use ingredients made for vaping: food-grade USP Vegetable Glycerin (VG), Propylene Glycol (PG), and professional e-liquid flavor concentrates. Skip random stuff like alcohol, soda, or anything not clearly labeled for vape use—there’s just no way to know it’s safe.
What You’ll Need: The Basic Ingredients
You only need four things to get started:
VG (Vegetable Glycerin) – Creates thick clouds and smooth vapor.
PG (Propylene Glycol) – Carries flavor really well and adds some throat hit.
Flavor concentrates – Popular brands include CAP, FA, and TFA. These are made specifically for e-liquid.
Nicotine base – 36 mg/ml is the sweet spot for most beginners.
That’s it. No fancy lab setup required.
Flavor Percentage: How Much Is Enough?
Most mixes use about 10% total flavor. Start there, then tweak to your taste—some people like 5-8%, others go up to 15%. Everyone’s palate is different, and that’s the whole point of DIY: finding the exact flavor you love. Test small batches and adjust.
Mixing Order: The Sequence That Works Best
The order matters for getting everything to blend nicely:
- Add your flavor to PG first and mix well (flavors dissolve better in PG).
- Add VG and stir or shake.
- Finally, add your nicotine base.
Some folks mix nicotine with PG first, then add flavor—either way works. After mixing, seal the bottle and let it “steep” (more on that below). Do this in a clean, quiet spot away from strong smells.
VG vs. PG: What’s the Difference and Which Ratio?
- VG gives you big, dense clouds and a smoother inhale. It’s thicker, so pure VG mixes can feel a bit syrupy at first.
- PG carries flavor better and gives a stronger throat hit. It’s thinner and can feel harsher on the throat and lungs for some people.
Common starting ratios (PG/VG):
- 70/30 or 80/20 for strong flavor and decent clouds
- 50/50 for balance
- 30/70 or 20/80 if you want massive clouds and smoother vapor
Pure VG is possible, but some flavors (especially menthol or mint) dissolve better with a splash of PG. Pure PG can feel too harsh for daily use. Try a few ratios and see what your setup and lungs prefer.
Where Does the “Throat Hit” Come From?
That satisfying “kick” in the back of your throat? It mostly comes from nicotine—the higher the strength, the stronger the hit. PG also adds a little. For new vapers it can feel itchy or uncomfortable at first; for long-time smokers it feels familiar. If it ever makes you dizzy or nauseous, drop the nicotine level.
PG Sensitivity—It’s More Common Than You Think
Some people (especially outside the U.S.) notice they don’t tolerate PG well: itchy skin, sore throat, nausea, or red patches. If that sounds like you, go low-PG or straight VG. It’s an easy fix once you know.
Nicotine Strength: What Should Beginners Use?
Start with 6 mg or 12 mg finished strength in your e-liquid. That covers most people’s needs without being overwhelming. Always calculate with a proper tool so you don’t overshoot. And again—never handle pure nicotine; 36 mg base is plenty strong and far safer.
Can You Mix with Pure VG Only?
Yes, but expect longer steeping and maybe a little cloud at first. Some flavors need a tiny bit of PG to dissolve properly. A bit of haze or cloudiness in pure VG mixes is totally normal and harmless.
What Is Steeping and Why Does It Matter?
Steeping just means letting the mixed e-liquid sit so the flavors meld and mellow. Three ways people do it:
- Shake it daily and let it sit at room temperature (most popular for natural results)
- Warm water bath (gentle heat)
- Ultrasonic cleaner (fastest)
Most experienced mixers swear by the “set it and forget it” method—give it a few days to a couple of weeks depending on the flavor. Fruit flavors steep fast; tobaccos and custards take longer.
Tools You Actually Need
Keep it simple:
- Empty bottles (plastic or glass)
- Syringes or pipettes for measuring
- Gloves
- Funnel if you’re messy
- Glass containers for high-nicotine work (nicotine can react with some plastics)
Once mixed, plastic bottles are fine for storage.
How Much Should You Mix at First?
Start small—10 ml batches. Once you nail the recipe, scale it up. No point wasting a liter on a flavor you end up hating.
E-Liquid Calculators: Your Best Friend
Free online calculators make this foolproof. Just punch in your total volume, desired nicotine strength, flavor percentage, and VG/PG ratio. They’ll tell you exactly how many ml of each ingredient to use (assuming 36 mg nicotine base). Search for “e-liquid calculator” and you’ll find several good ones.
Storing Your Finished Mix
Keep bottles in a cool, dark place—drawer, closet, anywhere away from direct sunlight and heat. Always child- and pet-proof the storage spot. Properly stored, homemade e-liquid lasts months.
Optional Additives (If You Want to Level Up)
Once you’re comfortable with the basics, some people experiment with:
- Throat-soothing agents (a few drops per 10 ml to soften high-nic mixes)
- Sweeteners (for fruit or dessert flavors)
- Coolants (for ice-cold hits without heavy menthol)
- Acetyl Pyrazine or tobacco extracts (for more realistic tobacco profiles)
- Tiny amounts of food-grade coloring (if you like colorful juice)
Use these sparingly—less is almost always more.
There you go—that’s the complete beginner-friendly roadmap. Take it slow, mix small, and enjoy the process of dialing in flavors you actually love. Once you get the hang of it, you’ll wonder why you ever bought pre-made juice. Stay safe, have fun, and happy mixing!
