Choosing your first e-liquid feels overwhelming. Walk into any vape shop and you’re staring at hundreds of bottles in every flavor and strength. Where do you even start?
It comes down to four decisions: nicotine type, nicotine strength, PG/VG ratio, and flavor. Get those right and you’ll have a decent experience from day one. Get them wrong and you’ll wonder why vaping gets so much hype. I bought the wrong juice my first time. Way too harsh, wrong device match, wasted money. Here’s how to avoid that.
Step 1: Pick Your Nicotine Type
This is the single biggest choice you’ll make. There are two types of nicotine in e-liquid: freebase and nicotine salts. They feel completely different.
Freebase nicotine is the traditional kind. It hits harder at higher strengths and gives you a noticeable throat hit. You’ll find it in 0mg, 3mg, 6mg, 12mg, and 18mg bottles. Great for sub-ohm and DTL vapers who want lower strengths with big clouds.
Nicotine salts are smoother. Way smoother. You can vape 20mg nic salt and it barely tickles your throat, whereas 20mg freebase would make you cough. Nic salts absorb faster too, so the craving relief hits quicker. Perfect for MTL pod vapers switching from cigarettes.
The short version: using a small pod device? Go nic salts. Using a big sub-ohm tank? Go freebase. Our nic salt vs freebase guide breaks this down in detail.
Step 2: Choose Your Nicotine Strength
Too much nicotine and you’ll feel dizzy and nauseous. Too little and you’ll keep reaching for cigarettes. Here’s how to dial it in based on your smoking habit.
| Smoking History | Nic Salt Strength | Freebase Strength |
|---|---|---|
| Light smoker (1 to 5 per day) | 10mg | 3mg |
| Moderate (5 to 15 per day) | 20mg | 6mg |
| Heavy (15 to 25 per day) | 20mg | 12mg |
| Very heavy (25+ per day) | 20mg + vape more often | 18mg |
Start at the strength that matches your habit. It’s easier to step down later than to start too low and cave in to a cigarette craving. I started at 20mg nic salt and dropped to 10mg within two months. No rush.
Step 3: Match the PG/VG Ratio to Your Device
PG (propylene glycol) carries flavor and gives throat hit. VG (vegetable glycerin) makes clouds and adds sweetness. The ratio between them determines how your juice behaves and which devices it works with.
| Ratio | Best For | Device Type |
|---|---|---|
| 50/50 | MTL pods, pen kits, beginners | Low power (10 to 20W) |
| 60/40 VG/PG | Pods with larger coils | Mid power (20 to 40W) |
| 70/30 VG/PG | Sub-ohm tanks, DTL kits | Higher power (40W+) |
| 80/20 VG/PG | Cloud chasers, advanced kits | High power (80W+) |
The key rule: thin juice (high PG) for small devices, thick juice (high VG) for big devices. Put 70/30 in a tiny pod and you’ll burn through coils. Put 50/50 in a sub-ohm tank and you’ll get weak flavor and leaking. Our PG vs VG guide goes deeper on why these ratios matter.
Most beginners start with 50/50 in a pod kit. It’s the safest bet. You can experiment once you know what you like.
Step 4: Pick a Flavor
Flavor is personal. Nobody can tell you what you’ll enjoy. That said, there are some patterns worth knowing.
Tobacco is the obvious starting point for switchers. It’s familiar. The downside? Most tobacco e-liquids don’t taste like cigarettes. They taste like sweet pipe tobacco or caramel. Don’t expect a Marlboro in a bottle. Some people love that. Others find it off-putting.
Menthol and mint are the most forgiving category. Even cheap mint juice tastes decent. Cool hits are satisfying, and the cold sensation masks harshness at higher nicotine strengths.
Fruit is the biggest category by far. Mango, strawberry, blueberry, watermelon. Fruit flavors are bright and easy to vape all day. They’re the default in disposables for a reason.
Dessert flavors (vanilla custard, caramel, pastry) are richer and heavier. Great for evenings. Not always great as an all-day vape because they can cause flavor fatigue.
My advice? Buy three small bottles in different categories. Try them for a week. You’ll know fast which direction to go. Don’t commit to a 100ml shortfill before you know what you like.
Device Compatibility Cheat Sheet
| Your Device | Nic Type | Ratio | Bottle Size |
|---|---|---|---|
| Pod kit (MTL) | Nic salts (10 to 20mg) | 50/50 | 10ml |
| Pen kit (MTL) | Freebase (6 to 12mg) or nic salts | 50/50 to 60/40 | 10ml |
| Sub-ohm tank (DTL) | Freebase (3 to 6mg) | 70/30 | Shortfill (50ml+) |
| Mod kit (DTL) | Freebase (3mg) | 70/30 to 80/20 | Shortfill (100ml+) |
This table saves you the trial and error. Match the row to your device and you’re 90% of the way there.
What About Shortfills?
Shortfills are large bottles of 0mg juice with space at the top for nicotine shots. They’re cheaper per ml than 10ml bottles. A 100ml shortfill plus two nic shots gives you 120ml of 3mg for way less than twelve separate 10ml bottles.
Catch is: shortfills are mostly 70/30 or 80/20 VG/PG. That rules out most pod kits. They’re built for DTL vapers at low nicotine strengths. Not for beginners on 20mg nic salts. Our shortfill guide covers the full breakdown.
With the UK Vaping Products Duty starting October 2026 (£2.20 per 10ml on all e-liquid, per the UK Government), shortfills still win on price. The margin shrinks, though. Stocking up before October and storing properly makes sense if you’re a DTL vaper.
Ingredient Safety in 2026
Something most beginner guides skip: the FDA added PG and VG to its Harmful and Potentially Harmful Constituents list in April 2026 (FDA HPHC list). This doesn’t mean fresh juice is dangerous. The concern is about breakdown products like formaldehyde and acrolein that form when e-liquid degrades or overheats on old coils. A 2025 PubMed 2025 review confirmed that the primary health concern with PG/VG inhalation is thermal degradation byproducts. Research published in 2024 found that PG/VG aerosols can affect airway inflammation (PubMed 2024).
What this means for you: buy from reputable brands, check expiration dates, store your juice properly, and change your coils regularly. Fresh juice on a good coil is low risk. Old degraded juice on a burnt coil is where problems start. Our vape juice expiration guide covers storage and shelf life in detail.
Common Beginner Mistakes
Buying the strongest nicotine because you smoked a lot. A 20mg nic salt in a sub-ohm tank at 80W will make you sick. Nicotine delivery depends on the device, not just the number on the bottle.
Using thick juice in a pod. 70/30 VG/PG in a pod with small wicking holes equals dry hits and burnt coils. Happens within hours, not days. Stick with 50/50 for pods.
Buying 100ml of one flavor. That mango might sound amazing in the shop. Three days in, you might hate it. Start with 10ml bottles until you find your all-day vape.
Ignoring coil compatibility. Your coil resistance determines what juice works. Coils above 1.0 ohm want 50/50. Coils below 0.5 ohm want 70/30 or higher. Check your coil specs.
Chasing clouds on day one. Cloud production comes from high VG, high wattage, and low nicotine. None of that matters when you’re trying to quit smoking. Focus on nicotine satisfaction first. The clouds can come later.
Frequently Asked Questions
What e-liquid should a beginner buy?
A 50/50 PG/VG nic salt at 10 to 20mg in a 10ml bottle, with a pod kit. This combination gives you the closest experience to smoking while keeping things simple. Check our beginner’s guide for device recommendations.
How do I know which nicotine strength to choose?
Base it on how many cigarettes you smoke per day. Under 10? Start at 10mg nic salt or 6mg freebase. Over 15? Go 20mg nic salt or 12mg freebase. You can always step down once the cravings ease.
Can I use any e-liquid in any vape?
No. Thick juice (high VG) won’t wick properly in small pod devices. Thin juice (high PG) can leak in sub-ohm tanks. Match your juice to your device using the compatibility table above.
What is the best flavor for new vapers?
Menthol or fruit. Menthol masks harshness at higher strengths. Fruit is universally appealing and easy to find. Avoid dessert or tobacco until you’ve got a few weeks of vaping under your belt.
Should I start with nic salts or freebase?
Most beginners do better with nic salts. The smoother throat hit at higher strengths makes the switch from cigarettes easier. Freebase is better once you’ve dropped your nicotine and want bigger clouds.
How much does e-liquid cost per month?
A pod vaper using one 10ml bottle per day of nic salt at roughly £3 to £5 per bottle will spend £90 to £150 per month. A DTL vaper using shortfills spends less per ml, around £40 to £80 per month. UK prices rise after October 2026 when the vape duty kicks in.
Is it normal for e-liquid to taste different after a few days?
Yes. This is called “vaper’s tongue” and it’s temporary. Your taste buds get fatigued from the same flavor. Switch flavors for a day or two, drink water, and it’ll come back. Sometimes it’s a sign your coil needs changing, though. Check that first.
