Understanding Longfill E-Liquids: A Simple Guide

The vaping community has seen exciting new developments, particularly in the world of e-liquids. One trend that has grown steadily is longfill e-liquids. At Skyline Vape Shop, we're here to provide you with insight into what makes longfill e-liquids unique and why they've become a favourite among vapers who like to customise their vape.

What Are Longfill E-Liquids?

Longfill e-liquids are designed with customisation in mind. Unlike pre-mixed e-liquids, a longfill is a combination of separate components, including flavour shots, VG (vegetable glycerin) shots, and nicotine shots, that you blend together to create your own personalised vape liquid. This flexibility lets you control the strength, flavour intensity, and type of nicotine in your vape.

Components of Longfill E-Liquids:

1. Flavour Shots: Concentrated flavour mixes, usually a blend of artificial and natural flavourings in a propylene glycol (PG) solution, sometimes with sweeteners or cooling agents.
2. VG Shots: Food-grade, 100% vegetable glycerin additives that give your vape cloud production and smoothness.
3. Nicotine Shots: Available as either freebase or salt nicotine in PG or VG solutions, nicotine shots let you adjust the strength of your vape; see our freebase vs nic salt guide if you're unsure which type suits you.

Combining these shots in the right proportions lets you create a fully customised, stable, ready-to-vape e-liquid.

Benefits of Longfill E-Liquids

Longfill e-liquids offer unique benefits that make them popular with vaping enthusiasts:

• Personalisation: Control your flavour, nicotine strength, and VG/PG ratio.
• Cost-Effectiveness: Buying separate components can work out more economical over time than pre-mixed bottles.
• Flexibility in Nicotine Choices: Choose between freebase and salt nicotine, making longfill suitable for both sub-ohm and MTL (mouth-to-lung) vaping styles. If you're not sure which nicotine level to mix to, our guide to finding your best nicotine strength is a good starting point.

Longfill DIY Guide: Mixing Tips and Recipes

Longfill e-liquids are simple to mix once you know the basics. Here are some recipes to get you started with freebase, MTL, and salt nic longfill e-liquids. Each recipe is diluted to the target strength across the full bottle volume, so the maths below works out exactly to the mg/ml listed.

120ml Freebase Longfill E-Liquid

• 0 mg: 30ml flavour shot + 80ml VG shot + 10ml 0mg PG shot
• 3 mg: 30ml flavour shot + 80ml VG shot + 10ml 36mg nicotine shot
• 6 mg: 30ml flavour shot + 80ml VG shot + 10ml 72mg nicotine shot

30ml MTL E-Liquid

• 12 mg: 15ml flavour shot + 15ml VG-based 24mg nicotine shot
• 18 mg: 15ml flavour shot + 15ml VG-based 36mg nicotine shot

30ml Salt Nic E-Liquid

• 25 mg: 15ml flavour shot + 15ml VG-based 50mg salt nic shot
• 35 mg: 15ml flavour shot + 15ml VG-based 70mg salt nic shot
• 50 mg: 15ml flavour shot + 15ml VG-based 100mg salt nic shot

How to Use Longfill E-Liquids

Here's a quick step-by-step guide to preparing your longfill e-liquid:

Step 1: Open Your Bottle

Remove the cap from the longfill bottle. You may need a bottle opener if it's a tight fit.

Step 2: Add the Shots

• For Freebase E-Liquid: Add your chosen nicotine shot (or 0mg PG shot) and VG shot to your 30ml flavour shot in a larger 120ml bottle.
• For Salt Nic/MTL E-Liquid: Add the nic shot to the 15ml flavour shot in a 30ml bottle. No separate VG shot is needed here, as the ratio is already adjusted to roughly 50/50 VG to PG.

Step 3: Shake It Up

Seal the bottle, replace the cap, and shake vigorously to make sure the components are thoroughly mixed. A well-blended e-liquid enhances flavour and consistency.

Step 4 (Optional): Steep Your E-Liquid

Steeping lets the flavours mature and develop more depth. For rich or dessert flavours, steeping for one to two weeks in a cool, dark place is recommended, though even a few hours can make a difference.

Step 5: Enjoy Your Vape

After shaking (and steeping, if you like), you're ready to vape. Fill your device and enjoy the flavour.

Frequently Asked Questions

Is mixing a longfill e-liquid safe to do myself?

Yes, as long as you use properly manufactured flavour shots, VG shots, and nicotine shots from a reputable source and follow the dilution ratios on the packaging. Always keep concentrated nicotine shots away from children and pets, and wear gloves if handling high-strength nicotine concentrate directly.

How long does a mixed longfill e-liquid last?

Once mixed, most longfill e-liquids are best used within a few months for optimal flavour, and should be stored in a cool, dark place away from direct sunlight and heat.

Can I make a nicotine-free longfill?

Yes. Simply use a 0mg PG shot in place of a nicotine shot, and the rest of the recipe stays the same.

What is the difference between a longfill and a shortfill?

A shortfill is a bottle already mixed with flavour and VG/PG but left with extra headroom for you to add a nicotine shot. A longfill goes a step further, letting you control the flavour shot, VG shot, and nicotine shot ratios independently for a fully custom mix.

Do I need any special equipment to mix longfills?

No special equipment is required. All you need is the bottle the flavour shot comes in (which has enough headroom for the other shots) and the shots themselves. Just add, seal, and shake.

Why Choose Longfill E-Liquids?

Longfill e-liquids go beyond just being vape juice; they are a way to make your vaping experience truly your own. The ability to mix your favourite flavours, tailor the nicotine level, and control the VG/PG ratio lets you craft an e-liquid that suits your taste. It may seem complex at first, but once you get the hang of it, longfills are an easy and rewarding way to vape.
