What Is Shortfill E-Liquid? Your Full 2026 UK Guide to Use

Shortfill e-liquid is a large bottle of nicotine-free vape juice with space left for a nicotine shot. You buy shortfill e-liquids because they let you customise nicotine strength while paying less per millilitre than standard 10ml bottles.

Manufacturers leave a gap at the top of every bottle on purpose. This gap holds 1 or 2 nicotine shots, so you decide exactly how strong your finished vape juice becomes.

This guide covers exact bottle sizes, mixing steps, storage rules, and cost comparisons for 2026. You get precise numbers throughout, so you can shop with confidence.

What Are Shortfill E-Liquids?

A shortfill e-liquid is any vape juice sold in a bottle above 10ml that contains 0mg nicotine by law. UK and EU rules ban nicotine-containing e-liquid in bottles over 10ml (0.34fl oz). Brands fill larger bottles short of the top instead.

You find shortfill e-liquids from named brands such as Dr Frost, Nasty Juice, and Bar Fills on UK shelves in 2026. Bottle sizes range from 30ml (1fl oz) up to 150ml (5fl oz). 50ml (1.7fl oz) and 100ml (3.4fl oz) remain the 2 most common fills.

Every shortfill bottle states its VG (Vegetable Glycerine) to PG (Propylene Glycol) ratio on the label. A 70VG/30PG mix produces thick clouds, while a 50VG/50PG mix gives a stronger throat hit with less vapour.

Shortfill e-liquids come in 4 broad flavour categories: fruit, menthol, dessert, and tobacco. Popular named flavours include watermelon ice, strawberry laces, custard tart, and classic tobacco blend.

The name shortfill comes directly from the bottle being filled short of its full capacity. Retailers and manufacturers both use this same term across the UK vaping market in 2026.

What Ingredients Do Shortfill E-Liquids Contain?

Shortfill e-liquids contain 3 core ingredients: Vegetable Glycerine (VG), Propylene Glycol (PG), and flavour concentrate. VG creates the thick vapour clouds associated with sub-ohm vaping.

PG carries flavour and produces the throat hit that mimics cigarette smoke. Flavour concentrates use food-grade ingredients tested to UK safety standards before bottling.

Every shortfill bottle also lists a batch number and expiry date on its label. Check both details before your first vape to confirm freshness and compliance.

UK manufacturers submit every recipe to the MHRA for notification before sale. This process checks ingredient safety, labelling accuracy, and child-resistant packaging compliance.

Why Do Shortfill E-Liquids Come Without Nicotine?

Shortfill e-liquids come without nicotine because the Tobacco Products Directive (TPD) caps nicotine-containing bottles at 10ml (0.34fl oz). The Medicines and Healthcare products Regulatory Agency (MHRA) enforces this rule across the UK.

The TPD came into force across the UK and EU in 2017, changing how manufacturers packaged nicotine e-liquid. Before 2017, vapers bought nicotine e-liquid in bottles up to 100ml (3.4fl oz) without any nic shot system.

The TPD also limits nicotine strength to 20mg/ml in the UK and EU. It restricts vape tank capacity to 2ml (0.07fl oz) too. These 3 rules pushed manufacturers to separate flavoured base liquid from nicotine.

You now buy the flavoured base as a shortfill and the nicotine separately as a nic shot. This system keeps large bottles legal while still letting you vape nicotine if you want it.

How to Mix a Nic Shot Into Your Shortfill E-Liquid

To mix a nic shot into your shortfill e-liquid, remove the cap and pour in your chosen nic shot. Replace the cap and shake the bottle for at least 60 seconds.

Most 60ml (2fl oz) bottles hold 50ml (1.7fl oz) of e-liquid. This leaves 10ml (0.34fl oz) of empty space for 1 nic shot. Larger 120ml (4fl oz) bottles hold 100ml (3.4fl oz) of e-liquid with room for 2 nic shots.

A single 10ml nic shot at 18mg strength added to a 50ml shortfill creates 60ml of e-liquid at 3mg. Adding 2 nic shots to a 100ml shortfill produces the same 3mg final strength across 120ml. Browse our nicotine shots UK range to match the correct strength to your bottle.

How to Pick the Right Nicotine Shot Strength

To pick the right nicotine shot strength, match it to your current cigarette habit or vaping history. Light smokers of fewer than 10 cigarettes a day usually suit 3mg e-liquid.

Heavier smokers of 20 cigarettes a day or more often need 2 nic shots per 50ml bottle. This combination produces a 6mg result. Ex-smokers who quit over 12 months ago frequently prefer 0mg shortfills with no nic shot at all.

How to Shake and Rest Your Mixed Shortfill

To shake and rest your mixed shortfill, shut the cap tightly and shake for 60 seconds. Leave the bottle standing upright for 5 minutes before your first vape.

This rest period lets the nic shot's PG base blend fully with the shortfill's VG-heavy formula. Skipping the rest step can leave uneven nicotine pockets inside the bottle.

What Bottle Sizes Do Shortfill E-Liquids Come In?

Shortfill e-liquids come in 5 common bottle sizes: 30ml (1fl oz), 50ml (1.7fl oz), 60ml (2fl oz), 100ml (3.4fl oz), and 120ml (4fl oz).

Larger 150ml (5fl oz) bottles from brands like Wicker's Choice also appear on UK shelves in 2026.

Every bottle uses a soft plastic body with a child-resistant cap and a narrow dropper nozzle. This design lets you pour a nic shot without spilling e-liquid on your hands or worktop.

50ml and 60ml Shortfill Bottles

To choose a 50ml or 60ml shortfill bottle, pick this size if you vape less than 5ml a day. A 60ml bottle holds 50ml of e-liquid with 10ml of empty space for exactly 1 nic shot.

100ml and 120ml Shortfill Bottles

To choose a 100ml or 120ml shortfill bottle, pick this size if you vape more than 5ml a day. A 120ml bottle holds 100ml of e-liquid with 20ml of empty space for 2 nic shots. Keep a few vape liquid empty bottles on hand for decanting large shortfills into travel-friendly sizes.

Which Vape Kits Suit Shortfill E-Liquids Best?

Shortfill e-liquids suit 2 main categories of vape kit: high VG kits and 50/50 kits. Your choice depends on the VG/PG ratio printed on the bottle label.

Coil resistance also determines which shortfill works best in your device. Coils rated below 1.0ohm need high VG e-liquid, while coils above 1.0ohm perform better with 50/50 blends.

Airflow settings on your tank also affect flavour delivery from either ratio. Open airflow suits high VG shortfills, while restricted airflow suits 50/50 blends in MTL kits.

High VG Shortfills for Sub-Ohm Kits

To use a high VG shortfill, choose a sub-ohm or direct to lung (DTL) kit rated above 40W. Box mod kits with coils below 0.5ohm handle 70VG/30PG shortfills best. Pair yours with one of our sub-ohm vape tanks for maximum cloud production.

50/50 Shortfills for MTL Kits

To use a 50/50 shortfill, choose a mouth to lung (MTL) kit rated at 35W or less. Pod systems and starter kits both handle 50VG/50PG shortfills without leaking or burning.

What Is the Difference Between Shortfill E-Liquid and Nic Salt E-Liquid?

Shortfill e-liquid uses freebase nicotine added by you through a separate nic shot. Nic salt e-liquid arrives pre-mixed at a fixed strength instead. Nic salts typically range from 10mg to 20mg and never exceed the 10ml (0.34fl oz) bottle limit.

Freebase nicotine in a mixed shortfill gives a stronger throat hit at the same strength as nic salts. Nic salt e-liquid absorbs faster into your bloodstream, which suits vapers switching directly from cigarettes.

Shortfill e-liquid works best in sub-ohm and higher-wattage kits, while nic salt e-liquid suits low-wattage pod kits. Choose a shortfill if you want large bottle volume and a custom nicotine strength.

What Mistakes Do New Shortfill Users Make?

New shortfill users make 3 common mistakes. These are adding the wrong nic shot strength, skipping the shake step, and using a high VG shortfill in a low-power kit. Each mistake leads to weak flavour or a harsh throat hit.

Adding 2 nic shots to a 50ml bottle instead of 1 doubles your nicotine strength by accident. Always check the bottle label for the correct nic shot count before you pour.

Skipping the 60-second shake step leaves nicotine unevenly mixed through the bottle. Your first few vapes taste weak while your last few vapes taste overly strong.

Using a 70VG/30PG shortfill in a 20W pod kit floods the coil and causes leaking. Match your bottle's VG/PG ratio to your device wattage every single time.

How Long Do Shortfill E-Liquids Last Once Opened?

An unopened shortfill e-liquid lasts up to 24 months from its manufacture date when stored below 25°C (77°F). Once you open the cap and add a nic shot, use the bottle within 6 months.

Flavour intensity fades gradually after the 6-month mark, even though the e-liquid remains safe to vape. Nicotine potency also drops slowly once oxygen enters the opened bottle.

Label your mixed bottle with the date you added the nic shot. This 1 habit stops you from vaping stale e-liquid past its best flavour window.

Who Should Use Shortfill E-Liquids?

Shortfill e-liquids suit 3 main types of vaper: heavy sub-ohm users, budget-focused vapers, and flavour-first vapers who want variety. Heavy sub-ohm users who vape more than 5ml a day save money. They do this by buying 100ml (3.4fl oz) bottles instead of 10ml bottles.

Budget-focused vapers benefit from the lower cost per millilitre that larger bottles offer. Flavour-first vapers enjoy trying named flavours such as watermelon ice, custard tobacco, and blue raspberry. This variety comes without committing to a full nicotine bottle.

New vapers switching from cigarettes often start with a 3mg or 6mg shortfill mix. Experienced vapers who already vape 0mg sometimes buy shortfills purely for their larger size and lower price.

Social vapers who share flavours with friends also gain from the larger bottle format. A single 100ml bottle lasts 1 person around 10 days at 10ml a day, or several friends a single evening.

What Does the Shortfill Mixing Process Look Like at a Glance?

The table below sets out every step, its timing, its method, and its difficulty level.

How to Store Shortfill E-Liquids Safely

To store shortfill e-liquids safely, keep bottles upright in a cupboard away from direct sunlight. Room temperature below 25°C (77°F) keeps flavour and nicotine stable for up to 24 months unopened.

Extreme heat above 25°C (77°F) breaks down flavour molecules faster than normal. Cold temperatures below 5°C (41°F) thicken the VG base and slow your first few puffs.

Once mixed with a nic shot, use the bottle within 6 months for the freshest flavour. Keep every bottle out of reach of children and pets at all times.

What Do Shortfill E-Liquids Cost Compared to 10ml Bottles?

A single 10ml (0.34fl oz) bottle of nicotine e-liquid costs roughly £4.99 in UK vape shops during 2026. Buying 10 separate 10ml bottles to match a 100ml shortfill costs around £49.90 in total.

A 100ml shortfill bottle plus 2 nic shots typically costs under £20 combined at retailers such as Vape Lounge Online. This pricing saves you more than £29 for the same 100ml (3.4fl oz) volume of nicotine e-liquid.

A 10ml bottle at £4.99 works out to roughly 50p per millilitre of e-liquid. A 100ml shortfill at £14.99 plus a £3.99 nic shot works out to roughly 19p per millilitre. That works out to a saving of over 60%.

A vaper who uses 10ml a day spends around £182 a month on 10ml bottles alone. The same vaper using shortfills spends closer to £57 a month, a yearly saving of over £1,500.

Frequently Asked Questions

Do shortfill e-liquids contain nicotine?

No, shortfill e-liquids contain 0mg nicotine until you add a nic shot yourself. The bottle stays nicotine-free on the shelf to meet TPD rules. You control every milligram added from that point forward.

Can you vape a shortfill without adding nicotine?

Yes, you can vape a shortfill e-liquid straight from the bottle at 0mg strength. Many flavour-first vapers choose this option every day. This route also suits vapers who already quit nicotine entirely.

How much nicotine does a 10ml nic shot add to a 50ml shortfill?

A 10ml nic shot added to a 50ml shortfill creates 60ml of e-liquid at 3mg strength. This ratio stays consistent across every 18mg nic shot brand. Adding 2 shots to a 100ml bottle gives the identical 3mg result.

What is the difference between a 50/50 and a high VG shortfill?

50/50 shortfills suit MTL kits at 35W or less, while high VG shortfills suit sub-ohm kits above 40W. Check your device wattage before you pick a bottle. Using the wrong ratio can cause leaking or a harsh throat hit.

Is shortfill e-liquid cheaper than 10ml bottles?

Yes, a 100ml shortfill bottle costs less per millilitre than 10 separate 10ml bottles. The saving grows larger the more e-liquid you vape each month. Heavy vapers often save over £1,000 a year switching to shortfills.
