How to choose your e-liquid: complete guide 2026

Why is choosing the right e-liquid crucial?

E-liquid is the fuel for your e-cigarette. A wrong choice—unsuitable nicotine level, an unappealing flavor, or an incompatible format—is the main reason some vapers give up and return to cigarettes. This guide will help you make the right choice from the start.

The 4 criteria for choosing your e-liquid

1. Nicotine level

This is the most important criterion, especially if you are a former smoker:

• 0 mg/ml — for vapers who have already quit nicotine
• 3 to 6 mg/ml — for light smokers (<10 cigarettes/day)
• 12 mg/ml — for moderate smokers (10-20 cigarettes/day)
• 18-20 mg/ml — for heavy smokers (>20 cigarettes/day)

Nicotine salts (nic salts) are an alternative to classic e-liquids: smoother on the throat at high concentrations, they are ideal for heavy smokers new to vaping.

2. PG/VG ratio

PG (propylene glycol) and VG (vegetable glycerin) determine the vapor texture:

• 50/50 PG/VG — ideal for pods and starter kits, good flavor rendition
• 70/30 VG/PG — more vapor, slightly muted flavors, for more powerful kits
• 100% VG — for big clouds, advanced use

3. Flavor

This is a matter of personal taste, but here are the main categories:

• 🍓 Fruity — the most popular, fresh and accessible for beginners
• 👬 Tobacco — to replicate the sensation of traditional cigarettes
• 🍬 Gourmet — vanilla, caramel, pastry... for those with a sweet tooth
• ❄️ Menthol — fresh and intense, very popular with former menthol cigarette smokers

4. Format

• 10 ml bottle — the standard format, TPD compliant, ideal for testing flavors
• 50-70 ml bottle (shortfill) — nicotine-free, to be topped up with a booster
• 200 ml bottle — for experienced vapers who have found their flavor

Mistakes to avoid

• ❌ Choosing a flavor too far from what you like — start with what's familiar
• ❌ Using a 70/30 VG e-liquid in a pod — too thick, it damages coils
• ❌ Buying a large format without having tested the flavor in 10ml first
• ❌ Ignoring the expiry date — an expired e-liquid loses its aromas and can be altered

Our OK Vape advice

If you're starting out, begin with a 10 ml fruity e-liquid with a nicotine level suited to your consumption. This combination offers the best satisfaction rate for new vapers. Once you've found your favorite flavor, switch to the large format to save money.
