The VG/PG ratio in your e-liquid fundamentally shapes your vaping experience, and choosing the right one depends on your device and preferences. This ratio always adds up to 100%, so a 70% VG liquid contains 30% PG. Let's break down the most common ratios and who they suit best.

50/50 E-Liquids: The Versatile Choice

Offering equal parts VG and PG, 50/50 blends strike a perfect balance between flavour intensity and vapour production. This ratio works with virtually any device, from basic vape pens to pod kits. The balanced consistency delivers good flavour, moderate clouds, and a satisfying throat hit—making it the go-to choice for beginners and those using MTL or RDL devices. Most nic salt e-liquids use this ratio because it complements higher nicotine strengths perfectly.

70/30 & 80/20 High VG: Cloud Chasers' Territory

High VG ratios (70% VG or higher) cater to sub-ohm vapers who prioritise cloud production and smooth inhalation. These thicker liquids require more powerful devices with larger coil openings to vaporise properly. The result? Massive vapour clouds with mellower throat hit. If you're into DTL vaping with sub-ohm tanks or rebuildable atomisers, high VG shortfills are your best friend. Just remember: these e-liquids typically come nicotine-free, requiring nic shots if you want nicotine content.

High PG Ratios: For Traditional Feel

While less common, high PG e-liquids (60% PG or more) deliver intense throat hit and exceptional flavour clarity. They're particularly popular with ex-smokers who crave that cigarette-like sensation. These thinner liquids work efficiently in basic devices, produce discreet vapour, and often feature tobacco flavours designed to replicate smoking experiences authentically.

E-liquid flavouring represents where science meets artistry. Premium brands employ flavour chemists who spend months perfecting single profiles, layering natural and artificial food-grade concentrates to create authentic taste experiences. These aren't random additions, each flavouring must be carefully selected to withstand heat, blend harmoniously, and deliver consistent taste from first puff to last drop.

Quality flavour concentrates dissolve into PG, which acts as the flavour carrier throughout your e-liquid. This is why PG-dominant liquids often taste more vibrant—the PG enhances flavour perception on your taste buds. However, VG contributes subtle sweetness that can complement certain flavour profiles beautifully, particularly desserts and creams.

What Are Shortfills?

Shortfills brilliantly navigate TPD regulations whilst offering value to sub-ohm vapers. These are larger bottles (typically 50ml, 100ml, or 120ml) filled with nicotine-free e-liquid, intentionally "short-filled" to leave room for nicotine shots. Because they contain zero nicotine, they're not restricted by the 10ml bottle size limit, allowing you to purchase greater volumes economically.

How to Use Shortfills

Using shortfills is straightforward: purchase your preferred shortfill alongside nicotine shots (10ml bottles of concentrated nicotine, usually 18mg). Add the nic shot to your shortfill bottle, shake vigorously, and you've created 60ml of e-liquid at your desired strength. For example, adding one 18mg nic shot to a 50ml shortfill creates 60ml of 3mg e-liquid—perfect for sub-ohm devices.

Want different nicotine strengths? Simply adjust the number of nic shots. Two shots in a 100ml shortfill create 120ml of 3mg liquid. Some advanced vapers use higher strength nic shots (like 18mg salt nic) to achieve 6mg in their shortfills. The flexibility is remarkable, and the cost savings substantial—50ml shortfills often cost less than buying five separate 10ml bottles.

Why Choose Shortfills?

Sub-ohm devices consume e-liquid quickly, sometimes 10ml per day. Buying multiple 10ml bottles becomes expensive and inconvenient. Shortfills solve this beautifully, offering 50-100ml in single purchases at better value. They're almost always high VG formulations (70% or higher) designed specifically for DTL vaping and cloud production. Popular among experienced vapers, shortfills represent smart economics without sacrificing quality.

Nicotine shots, or "nic shots," are 10ml bottles containing concentrated nicotine in a PG, VG, or mixed base. They exist specifically to add nicotine to shortfills, and they're TPD-compliant since they're sold in 10ml quantities. Standard nic shots contain 18mg freebase nicotine, though nic salt variations are available for smoother results.

When selecting nic shots, consider the VG/PG ratio to maintain your desired final mix. If you're adding to a 70VG shortfill, using a 70VG nic shot preserves that ratio. However, many vapers use 50/50 nic shots without issue, as the small quantity doesn't dramatically alter the final ratio. Some brands offer "nic salt shots" which provide smoother nicotine delivery even when mixed into high VG liquids.

Calculating Nicotine Strength

What is Mouth-to-Lung Vaping?

MTL vaping mimics cigarette smoking by drawing vapour into your mouth before inhaling into lungs. These devices feature tighter airflow, producing less vapour but delivering concentrated flavour and satisfying throat hit. Pod kits, vape pens, and starter kits typically operate in MTL mode, making them ideal for beginners and ex-smokers.

Best E-Liquids for MTL

MTL devices work best with 50/50 VG/PG e-liquids or high PG formulations . The thinner consistency wicks efficiently through smaller coil openings, preventing dry hits. This is where nic salts truly shine—their smooth delivery at 10-20mg strengths satisfies cravings effectively without harshness. Freebase nicotine works brilliantly too, typically in 6mg, 12mg, or 18mg strengths.

Flavour profiles that excel in MTL include tobacco blends, menthol, single-fruit flavours, and beverages. The concentrated flavour delivery means you'll taste every nuance. Avoid shortfills in MTL devices—they're too thick and usually too low in nicotine. Stick with 10ml bottles designed for pod systems, and you'll enjoy reliable, satisfying performance every time.

Recommended Nicotine Strengths

• Light smokers (1-5 daily): 5-10mg nic salt or 3-6mg freebase
• Moderate smokers (10-15 daily): 10-15mg nic salt or 6-12mg freebase
• Heavy smokers (20+ daily): 20mg nic salt or 12-18mg freebase

Understanding Direct-to-Lung Vaping

DTL vaping involves inhaling vapour directly into your lungs, like taking a deep breath. Sub-ohm devices use coils with resistance below 1.0Ω and operate at higher wattages, producing substantial vapour clouds. These powerful kits demand more e-liquid but deliver intense flavour and visual satisfaction through impressive vapour production.

Ideal E-Liquids for Sub-Ohm

High VG shortfills are the gold standard for sub-ohm vaping. Ratios of 70/30 or 80/20 VG/PG provide the thick consistency needed for big clouds whilst maintaining flavour. These liquids handle high temperatures well, delivering smooth, flavourful vapour without harshness. Because sub-ohm devices consume so much liquid, the larger volumes and better value of shortfills make economic sense.

Nicotine strength should be low in sub-ohm vaping—typically 3mg or 6mg maximum. The sheer volume of vapour you inhale means higher strengths become overwhelmingly strong and harsh. One 18mg nic shot per 50ml shortfill creates perfect 3mg strength for most DTL vapers. Some experienced users prefer zero-nicotine shortfills, vaping purely for flavour and cloud production.

Flavour Recommendations

Sub-ohm vaping excels with complex, layered flavours: desserts, custards, creamy blends, and intricate fruit combinations. The increased vapour production and heat bring out subtle flavour notes that might go unnoticed in MTL devices. Bakery-style e-liquids particularly shine in sub-ohm setups, where the warmth enhances rich, indulgent profiles beautifully.

Restricted Direct-to-Lung (RDL) vaping sits between MTL and DTL, offering moderate clouds with good flavour. Many modern pod mods operate in RDL mode, appealing to vapers who want versatility. These devices work with both 50/50 e-liquids and high VG formulations, though 60/40 or 70/30 ratios often perform best.

Nicotine strength flexibility is RDL's advantage. You can comfortably use 6-12mg freebase or 10-20mg nic salts depending on airflow settings. Open the airflow for airier draws with lower nicotine; tighten it for restricted hits with higher nicotine. This adaptability makes RDL devices excellent for vapers transitioning from MTL to DTL, or those wanting one device for different occasions.

Fruit e-liquids dominate vaping for good reason—they're refreshing, versatile, and appeal to virtually everyone. These flavours range from single-fruit profiles like pure strawberry or mango to complex medleys blending multiple fruits with cooling menthol or icy notes. Fruit blends work across all device types and nicotine formulations, making them universally accessible.

Popular Fruit Categories

• Berries: Strawberry, blueberry, raspberry, and blackcurrant lead this segment, offering sweet-tart profiles that vape beautifully. Berry blends often combine multiple berries for complexity.
• Tropical: Mango, pineapple, passion fruit, and guava deliver exotic sweetness. These pair wonderfully with ice or menthol for refreshing all-day vapes.
• Citrus: Lemon, lime, orange, and grapefruit provide zesty brightness. Often blended with other fruits or menthol, citrus adds tangy character.
• Mixed Fruit: Combinations like fruit punch, tropical mix, or summer fruits offer layered taste experiences that keep your palate interested.

Fruit flavours particularly excel in nic salt formulations, where their natural sweetness complements smooth nicotine delivery. In high VG shortfills, fruits create flavourful clouds perfect for extended vaping sessions without palate fatigue.

Menthol and ice flavours provide cooling sensations that enhance other profiles or stand alone for pure refreshment. Since menthol cigarettes were banned in the UK, these e-liquids have surged in popularity among ex-menthol smokers. The cooling effect comes from menthol crystals or cooling agents like koolada, which activate cold receptors without actually lowering temperature.

These flavours range from subtle mint freshness to intense ice blasts. Spearmint, peppermint, and eucalyptus offer classic mint profiles, whilst "ice" variants add pronounced cooling to fruits, beverages, or standalone. Many vapers appreciate menthol's palate-cleansing properties, making it excellent for all-day vaping without flavour fatigue. Menthol also enhances throat hit, which appeals to those seeking cigarette-like sensation.

Dessert e-liquids recreate the comfort of cakes, cookies, custards, and confectionery without the calories. These rich, complex flavours shine in sub-ohm devices where warmth brings out creamy, bakery notes beautifully. Popular profiles include vanilla custard, strawberry cheesecake, lemon tart, caramel waffle, and chocolate fudge brownie.

Sweet flavours utilise carefully balanced sweeteners to replicate sugar without being cloying. Premium dessert e-liquids layer multiple flavour notes—perhaps biscuit base, cream filling, and fruit topping—to create authentic taste experiences. These work wonderfully as evening vapes or when you're craving something indulgent. Some vapers alternate between fruity daytime vapes and dessert evening selections.

Candy and confectionery flavours like gummy bears, sherbet, bubblegum, and cola bottles appeal to those who enjoy nostalgic sweetness. These tend to be sweeter than desserts but equally satisfying for sweet-toothed vapers.

Tobacco e-liquids serve ex-smokers seeking familiar taste without combustion. These aren't simple cigarette flavours—they range from bright Virginia tobacco to robust Cuban cigars, with variations including sweet pipe tobacco, nutty blends, and smoky notes. Some incorporate vanilla, honey, or caramel for added complexity.

Modern tobacco e-liquids have evolved significantly, offering sophisticated profiles that capture tobacco's earthy, nutty character without ash or burnt taste. They're particularly popular in MTL devices with higher nicotine strengths, where they provide the closest approximation to smoking experiences. Many ex-smokers start with tobacco flavours before gradually exploring fruity options.

Beverage-inspired e-liquids recreate your favourite drinks in vapeable form. Coffee profiles range from simple espresso to elaborate caramel macchiato or vanilla latte. Tea flavours offer everything from classic English breakfast to exotic chai or refreshing iced tea. Soft drinks like cola, lemonade, and energy drinks provide fizzy, sweet vaping experiences.

Cocktail and alcoholic beverage flavours have grown popular too—think mojito, piña colada, or whiskey notes. These sophisticated profiles often blend multiple elements: fruit, mint, cream, or spice to recreate complex beverages. Beverage flavours work across device types, though coffee and cream-based options particularly excel in warmer sub-ohm setups.

For MTL/Pod Device Users

For Sub-Ohm/DTL Device Users

Sub-ohm vaping produces significantly more vapour, meaning you inhale far more nicotine per puff. Even heavy smokers typically use just 3mg in sub-ohm devices. The large vapour volume makes higher strengths overwhelmingly harsh and potentially nauseating. Here's the general guidance:

• Most vapers: 3mg (one nic shot per 50ml shortfill)
• Heavy smokers initially: 6mg (two nic shots, though this becomes harsh)
• Cloud chasers: 0mg (zero nicotine, purely for flavour and clouds)

Attempting 12mg or 18mg in sub-ohm devices causes extremely harsh throat hit and potential nicotine overdose symptoms. The power and vapour volume simply aren't compatible with high nicotine concentrations. If 3mg doesn't satisfy you, consider switching to MTL devices rather than increasing nicotine in sub-ohm setups.

Nicotine Strength Too High

• Harsh, unpleasant throat hit that makes you cough
• Headaches or light-headedness after vaping
• Nausea or stomach discomfort
• Racing heart or jittery feelings
• Having to take very short, tentative puffs

Nicotine Strength Too Low

• Constantly vaping without feeling satisfied
• Cravings persist despite frequent vaping
• Finding yourself reaching for cigarettes
• Getting through e-liquid extremely quickly
• Feeling the need to vape continuously

Both scenarios indicate adjustment needed. Nicotine strength isn't permanent—many vapers start higher and gradually reduce over time. Don't hesitate to try different strengths until you find what works. Most reputable shops offer sample sizes or multi-buy deals that let you test various options affordably.

Correct storage preserves e-liquid quality and extends shelf life. E-liquids contain ingredients sensitive to light, heat, and air exposure, which can degrade flavour and nicotine over time. Follow these guidelines to maintain freshness:

Storage Best Practices

• Keep bottles sealed: Exposure to air oxidises nicotine, turning e-liquid darker and altering taste. Always close bottles tightly immediately after use.
• Store in cool, dark places: Cupboards or drawers away from windows work perfectly. Heat and UV light accelerate degradation.
• Avoid extreme temperatures: Don't leave e-liquids in cars during summer or winter. Room temperature (15-25°C) is ideal.
• Check expiry dates: Most e-liquids last two years sealed, one year opened. Using expired liquids isn't dangerous but flavour and nicotine potency diminish.
• Keep away from children and pets: Store e-liquids securely, preferably in locked cupboards. Nicotine is toxic if ingested.

Steeping: Does It Help?

Steeping involves letting e-liquid rest to allow flavours to mature and blend. Some complex blends, particularly desserts or tobacco, benefit from 1-2 weeks steeping in dark cupboards. Shake bottles occasionally during steeping. However, most modern e-liquids are pre-steeped and ready to vape immediately.

Handling E-Liquids Safely

Whilst e-liquids are designed for vaping, they require respectful handling. Nicotine, even in dilute form, can be harmful if mishandled. Follow these safety protocols:

• Avoid skin contact: Nicotine absorbs through skin. If e-liquid spills on you, wash immediately with soap and water.
• Never ingest: E-liquids are for vaping only. Accidental ingestion requires immediate medical attention.
• Use childproof caps: All e-liquids should have child-resistant closures. Ensure they're properly secured.
• Dispose responsibly: Don't pour e-liquid down drains. Many vape shops accept empty bottles for recycling.
• Check for allergies: PG sensitivity exists in some people. If you experience persistent irritation, try high VG liquids.

Understanding TPD Compliance

TPD regulations exist to protect consumers through quality standards, maximum nicotine concentrations, and mandatory testing. Every compliant e-liquid displays batch numbers, ingredient listings, and health warnings. Purchasing from reputable UK retailers ensures you receive properly regulated, tested products.

E-liquid composition affects how long your coils last. Sweeter e-liquids containing more sweeteners create residue ("coil gunk") that reduces coil life. High VG liquids, being thicker, can also clog coils faster in devices not designed for them. Here's how to maximise coil longevity:

• Choose e-liquids appropriate for your device's specifications
• Avoid excessively sweet liquids if coil life concerns you
• Prime new coils properly before first use
• Let e-liquid saturate wicking material between puffs
• Regular cleaning and maintenance extend coil life

Some e-liquid brands have developed coil-friendly e-liquids with reduced sweeteners. While these liquids may taste slightly less sweet, they help extend coil life, saving you money over time. This makes them a practical choice, especially for frequent vapers.

There is no single answer to what the best vape juice UK users should choose, as taste preferences vary widely from person to person. When selecting a high-quality e-liquid UK, many users look at factors such as ingredient transparency, flavour balance, throat hit, nicotine formulation, and the overall range of flavours available. While some e-liquids use natural extracts, this alone does not define quality. In the UK market, established brands like Bar Juice 5000, Elfliq, and Zeus Juice are frequently regarded as reliable options due to their consistent flavour profiles and wide appeal among different types of vapers.

Absolutely! Mixing flavours is a fun way to create custom blends. However, ensure you're combining compatible VG/PG ratios and similar nicotine types (don't mix nic salts with freebase). Start with small amounts to test combinations before mixing entire bottles. Some flavours complement each other beautifully—strawberry and cream, menthol and fruit, vanilla and tobacco—whilst others clash. Experimentation is part of the fun!

E-liquid naturally darkens over time through nicotine oxidation—a normal chemical process that doesn't indicate spoilage. This happens faster with higher nicotine strengths or when exposed to light and heat. Slight colour change is harmless, though very old e-liquids might lose flavour intensity. If e-liquid smells off or tastes considerably different, it's probably past its prime and worth replacing.

No—matching e-liquid to device type is crucial. High VG shortfills are too thick for MTL devices with small coil openings, causing dry hits and poor performance. Conversely, high PG liquids in sub-ohm tanks produce weak vapour and harsh experiences. Always check device recommendations: MTL devices need 50/50 or high PG liquids, whilst sub-ohm devices require high VG formulations. Using appropriate e-liquids ensures optimal performance, flavour, and coil longevity.

Premium e-liquids typically invest more in quality ingredients, flavour development, and testing. They use pharmaceutical-grade bases, sophisticated flavour concentrates, and undergo extensive quality control. Budget options can still be good, but might use simpler flavour profiles or less refined ingredients. However, price doesn't always indicate quality, some mid-range brands offer excellent value. Reading reviews and trying samples helps identify best options for your budget and taste preferences.

E-liquids have typical shelf lives of two years sealed, one year opened when stored properly. They don't become harmful after expiry but lose potency and flavour. VG and PG are naturally stable preservatives, but nicotine degrades over time, especially when exposed to air, light, or heat. Always check expiry dates before purchasing and rotate stock to use older bottles first. Properly stored e-liquids maintain quality for their full shelf life.
