Vape Flavours Explained: PG/VG Ratios, Nicotine Strengths and How to Choose
One of the most common questions among new and experienced vapers alike is how to choose the right vape flavour. With dozens of e-liquid options available in the UAE market, understanding the basics of vape flavour components — PG, VG, nicotine strengths, and flavour profiles — can help you find a vape that suits your personal preference.
PG and VG: The Foundation of Vape Flavour
Every e-liquid contains two primary base ingredients: propylene glycol (PG) and vegetable glycerin (VG). The ratio between these two ingredients significantly affects your vaping experience, including flavour intensity, throat hit, and vapour production.
Propylene Glycol (PG)
PG is a thin, odourless liquid that carries flavour more effectively than VG. It produces a stronger throat hit — similar to the sensation of smoking a traditional cigarette. E-liquids with higher PG content deliver more intense flavour and a more noticeable throat hit but produce less visible vapour.
Common PG ratios in e-liquids: 30-50% PG
Vegetable Glycerin (VG)
VG is a thicker, slightly sweet liquid that produces dense, voluminous vapour clouds. It delivers a smoother inhale with less throat hit. However, VG carries flavour less efficiently than PG, so high-VG liquids may taste slightly less intense.
Common VG ratios in e-liquids: 50-80% VG
Common PG/VG Ratios and Their Effects
| Ratio | Best For | Throat Hit | Vapour Production | Flavour Intensity |
|---|---|---|---|---|
| 50PG / 50VG | Balanced all-round vaping | Medium | Medium | High |
| 30PG / 70VG | Cloud chasing, smooth hits | Low | High | Moderate |
| 40PG / 60VG | Disposable vapes, pods | Medium-Low | Medium-High | Good |
| 20PG / 80VG | Sub-ohm devices | Very Low | Very High | Subtle |
Nicotine Strengths Explained
Nicotine strength is measured in milligrams per millilitre (mg/mL). The right nicotine strength depends on your previous smoking habits and personal preference.
| Strength | Label | Suitable For |
|---|---|---|
| 0 mg | Nicotine-Free | Flavour-only vaping |
| 3 mg | Low | Light smokers, sub-ohm vapers |
| 6 mg | Medium-Low | Moderate smokers |
| 12 mg | Medium | Regular smokers |
| 18 mg | High | Heavy smokers |
| 20 mg (2%) | Very High | Heavy smokers, nicotine salt users |
| 50 mg (5%) | Maximum | Former heavy smokers, high-nicotine preference |
In the UAE, all nicotine-containing e-liquids sold through licensed retailers comply with ESMA maximum concentration limits. Nicotine salt e-liquids (typically 20-50 mg) provide a smoother throat hit at higher strengths compared to freebase nicotine.
Types of Vape Flavour Profiles
E-liquid flavours generally fall into several broad categories:
Fruit Flavours
Fruit flavours remain among the most popular choices globally. Common options include strawberry, watermelon, mango, blueberry, and mixed fruit blends. These flavours are generally sweet, refreshing, and easy to vape all day.
Menthol and Mint
Menthol and mint flavours provide a cool, refreshing sensation. They are particularly favoured by former menthol cigarette smokers and users who prefer a clean, crisp taste. Many fruit flavours also include a “cool” or “ice” version with added menthol.
Dessert and Bakery
Dessert-inspired flavours include vanilla custard, caramel, chocolate, cheesecake, and baked goods like donuts or cookies. These tend to be richer and sweeter, often preferred by users who enjoy a more indulgent vaping experience.
Beverage Flavours
Coffee, cola, lemonade, and energy drink flavours are common in the beverage category. These provide a familiar taste experience that many users find satisfying, particularly with morning coffee or as an afternoon refreshment.
Tobacco Flavours
Tobacco-flavoured e-liquids aim to replicate the taste of traditional cigarettes. They range from light, mild blends to rich, robust tobacco profiles. These are most commonly chosen by smokers who are transitioning to vaping and want a familiar taste.
How to Choose the Right Vape Flavour
Choosing a vape flavour is a personal process. Here are practical tips to help you find your preferred taste:
- Consider your former smoking habits — If you are switching from cigarettes, you may prefer tobacco or menthol flavours initially. Many smokers find these flavours ease the transition.
- Try fruit flavours first — Fruit flavours are the most universally liked and offer a clean, pleasant taste that is easy to vape regularly.
- Check the PG/VG ratio — Higher PG delivers more flavour intensity; higher VG provides smoother hits with more vapour. Disposable vapes typically use a balanced ratio optimised for their specific device.
- Start with a familiar taste — Think about flavours you enjoy in food and drink. If you like strawberries in real life, a strawberry e-liquid is a safe starting point.
- Consider nicotine strength carefully — Too much nicotine can make even the best flavour unpleasant. Choose a strength appropriate to your usage level.
Summary
Vape flavour is determined by three key factors: the PG/VG ratio of the e-liquid, the nicotine strength, and the flavouring compounds used. PG carries flavour and provides throat hit, while VG produces vapour and smooths the inhale. Understanding how these components work together helps you select e-liquids that match your personal preferences. The UAE regulatory framework ensures that all licensed vape products meet safety and quality standards, giving consumers confidence in the products available through longer periods without degradation.
E-Liquid Storage and Shelf Life
Proper storage of e-liquids is essential for maintaining flavour quality over time. All e-liquids have a finite shelf life, typically ranging from one to two years from the manufacturing date when stored correctly. The three main enemies of e-liquid freshness are heat, light, and air exposure. Nicotine, the most sensitive component in e-liquids, oxidises when exposed to oxygen, causing the liquid to darken and develop a peppery or harsh taste over time. This process accelerates significantly in warm temperatures, making proper storage particularly important in the UAE climate.
Store e-liquids in a cool, dark cabinet away from direct sunlight and heat sources. Refrigeration can extend shelf life for nicotine-containing e-liquids, but allow the bottle to return to room temperature before use to avoid condensation inside the bottle. Always close bottles tightly after use to minimise air exposure. For disposable vapes, the e-liquid is sealed in an airtight chamber, which preserves freshness for the device’s intended lifespan. Most disposable vapes have a shelf life of 12 to 18 months from manufacture, clearly indicated on the packaging. Checking manufacturing dates and storage conditions helps ensure you enjoy e-liquids at their optimal flavour quality.
Mixing and Matching Flavours
For users with refillable devices, mixing e-liquids opens up a world of flavour possibilities. Simple combinations like adding a few drops of menthol to a fruit flavour, blending vanilla with tobacco, or mixing two fruit flavours to create a custom blend can transform your vaping experience. When experimenting with flavour combinations, start with small quantities to test the result before committing to a larger batch.
Keep notes on successful combinations so you can recreate them. For disposable vape users, switching between different brands and flavour profiles serves a similar purpose, allowing you to discover which flavour families you prefer without committing to a full bottle. The UAE market offers an increasingly diverse range of flavour options across licensed retailers, from traditional fruit and mint profiles to more adventurous dessert, beverage, and tobacco blends. By exploring different combinations and understanding how flavours interact, you can develop a personalised vaping experience that remains satisfying over time and helps prevent the palate fatigue that often comes with vaping a single flavour exclusively.

How Flavour Perception Works in Vaping
Vape flavour perception involves both taste and smell working together. The human tongue can detect five basic tastes: sweet, sour, salty, bitter, and umami. What vapers experience as “flavour” is actually a complex interaction between these taste sensations and aromatic compounds detected by olfactory receptors in the nose. This is why a blocked nose can make your vape taste bland, and why the same e-liquid can taste different to different people.
Genetic variations in taste receptors mean that some individuals are more sensitive to certain flavour compounds than others. Some vapers find that their flavour perception changes over time as their palate adjusts. Taking regular breaks from vaping, staying hydrated, and occasionally switching between different flavour profiles can help maintain consistent flavour perception and prevent palate fatigue. Understanding this biological aspect of vaping helps users set realistic expectations and appreciate why flavour preferences are deeply personal.
Understanding Vape Tongue and How to Prevent It
Vape tongue, also known as olfactory fatigue or vaper’s tongue, is a temporary condition where a familiar e-liquid flavour suddenly becomes muted or completely undetectable. This occurs when your olfactory receptors become overstimulated by repeated exposure to the same flavour compounds, causing them to temporarily stop sending signals to your brain. The condition is not permanent and typically resolves within a few days.
To prevent or recover from vape tongue, try switching between different flavour profiles rather than vaping the same flavour exclusively. Staying well hydrated helps — dehydration concentrates flavour compounds in your mouth and nasal passages. Some vapers find that smelling coffee beans, eating citrus fruits, or using a tongue scraper helps reset their palate. Having two or three devices with different flavours and rotating between them throughout the day is an effective long-term prevention strategy that many experienced vapers use.
How Different Coil Types and Temperatures Affect Flavour
The coil in your vaping device plays a critical role in flavour reproduction. Lower wattage coils operating at cooler temperatures preserve more delicate flavour compounds, producing a cleaner, more nuanced taste. Higher wattage coils generate more heat, which can intensify certain flavour notes while potentially muting or burning off more volatile compounds.
Mesh coils, now common in many modern devices, provide a larger heating surface area that vaporises e-liquid more evenly than traditional round wire coils. This even heating reduces hot spots and produces more consistent flavour throughout the device’s lifespan. Ceramic coils offer another alternative, providing exceptionally smooth flavour but typically requiring slightly higher power consumption. For disposable vapes, manufacturers carefully tune the coil design and power output to match the specific e-liquid formulation, which is why trying different brands and models can reveal surprisingly different flavour experiences even with similar flavour profiles.
