E-Liquid Buying Guide: How to Select the Right Vape Juice

With so many vape juice options on the market, finding the perfect e-liquid can feel overwhelming, especially if you’re new to vaping. From flavour profiles and nicotine strengths to PG/VG ratios and bottle sizes, there’s a lot to consider when choosing the right e-liquid vape. But don’t worry this handy buying guide from Astrovape breaks it all down for you.

1. Understand the Basics of E-Liquid

E-liquid, also known as vape juice, is the substance used in vape kits and e-cigarettes to produce vapour. It typically contains four main ingredients:

• Propylene Glycol (PG): A thinner liquid that carries flavour well and offers a stronger throat hit.
• Vegetable Glycerine (VG): A thicker liquid that produces more vapour and offers a smoother inhale.
• Flavourings: These give your e-liquid its unique taste, from fruits and desserts to menthol and tobacco.
• Nicotine (optional): Available in varying strengths or completely nicotine-free.

Understanding these elements will help you make an informed choice tailored to your vaping preferences.

2. Choose the Right Nicotine Strength

Nicotine strength is crucial for both satisfaction and safety. The right strength depends on your previous smoking habits and how often you vape.

• 0mg: Ideal if you’re only vaping for flavour and don’t need nicotine.
• 3mg–6mg: Suitable for light smokers or those who are slowly reducing their nicotine intake.
• 10mg–20mg (Nic salts): Perfect for heavier smokers or those looking for a stronger hit with a smoother throat feel.

If you’re unsure, start lower you can always go up, but it’s harder to go down once you’ve adjusted to a higher strength.

3. Pick a PG/VG Ratio That Suits Your Device

Not all vape juices work well with every device. The PG/VG ratio can significantly affect both performance and experience:

• High PG (e.g. 70/30): Best for mouth-to-lung (MTL) vaping with smaller kits or pod systems. Delivers a stronger throat hit with less vapour.
• High VG (e.g. 70/30 VG): Best for sub-ohm (direct-to-lung) devices. Produces dense vapour and a smoother inhale.
• 50/50: A balanced option, compatible with most devices and ideal for beginners.

Always check your device’s coil and wattage compatibility before choosing your PG/VG blend.

4. Explore a Variety of Flavours

The beauty of vaping is the wide variety of flavours. At Astrovape, you’ll find everything from bold tobacco and icy menthol to fruity explosions and indulgent desserts.

Here’s a quick breakdown of popular flavour categories:

• Fruity: Think mango, blueberry, cherry, or exotic fruit blends.
• Dessert: Custards, cakes, and creamy creations for sweet-toothed vapers.
• Menthol/Ice: Clean, refreshing, and cool on the exhale.
• Tobacco: For those who prefer a more traditional, earthy taste.
• Drinks: Cola, coffee, or energy drink-inspired vapes.

Don’t be afraid to experiment with different profiles until you find the ones that suit your taste buds.

5. Consider Shortfills vs Nic Salts

Depending on how you vape, you’ll want to choose between shortfills and nic salts:

• Shortfills (usually 100ml bottles): These are nicotine-free e-liquids that leave space in the bottle to add a nic shot. They’re ideal for sub-ohm vapers who prefer large clouds and lower nicotine.
• Nic Salts (usually 10ml bottles): Pre-mixed with nicotine, nic salts offer a smoother inhale and quicker nicotine absorption — perfect for new vapers or those trying to quit smoking.

Shortfills are more cost-effective in the long run, while nic salts offer convenience and strong nicotine delivery.

6. Check the Brand Quality

There’s a huge range of vape juice brands, but not all are created equal. At Astrovape, we stock only trusted, TPD-compliant e-liquid brands known for quality and safety. Whether you’re buying ELFLIQ, Drip Liquids, or Aspire-compatible juices, you’re guaranteed clean ingredients, accurate labelling, and consistent performance.

Always avoid unregulated products or anything that seems suspiciously cheap — your health and device are worth the investment.

7. Match the E-Liquid to Your Vape Kit

Different devices work best with certain types of e-liquid:

• Pod kits: Best with 50/50 or high-PG nic salts.
• Sub-ohm kits: Best with high-VG shortfills and low nicotine.
• Starter kits: Often compatible with most 50/50 blends.

Choosing the wrong e-liquid for your device can lead to leaks, burnt coils, or poor flavour, so always pair wisely.

8. Don’t Be Afraid to Experiment

Vaping is all about personal preference. You might love a blueberry nic salt today and switch to a creamy vanilla shortfill next week. Try a few smaller bottles before committing to a larger one. At Astrovape, we make exploring easy with a huge range of affordable, high-quality options.
