Ohm Brew Badass Blend Sour Blueberry 50ml: overview and key specs

Ohm Brew Badass Blend Sour Blueberry is a 50ml shortfill e-liquid from the Ohm range, made for people who run refillable vape kits and want a fruit flavour with a tart edge rather than a flat, sugary berry. Blueberry carries the base of the recipe, and a sour note runs through the inhale and exhale so the flavour does not collapse into a one-note blueberry syrup. If you have tried sour sweets and liked the way the tang cuts through the sweetness, you already understand what this liquid is aiming for.

It is sold as a shortfill, which means the bottle holds 50ml of flavoured liquid with no nicotine added, and the bottle itself is larger than 50ml so you have room to add nicotine shots if you want them. That format is common in the UK because it lets you buy a large volume of liquid while staying inside the rules on nicotine-containing bottle sizes. If you vape at 0mg you can use it straight from the bottle.

Here are the details that matter before you buy:

• Brand and range: Ohm Brew, Badass Blend
• Flavour: Sour Blueberry, a fruit profile with a tangy finish
• Liquid volume: 50ml of flavoured e-liquid
• Format: Shortfill, supplied at 0mg/ml nicotine, with headroom in the bottle for nicotine shots
• VG/PG balance: High-VG blend, typically 70VG/30PG in this style of range. Always confirm the exact ratio on the label of the bottle you receive
• Intended hardware: Sub-ohm tanks and kits designed for high-VG liquid, plus any pod or tank system that lists support for 70VG
• Nicotine after mixing: Roughly 3mg/ml with one 10ml 18mg shot, or 0mg/ml with none

The rest of this guide goes through the flavour, how it performs, what hardware suits it, how to work out your nicotine strength, and where it makes sense compared with the alternatives. Everything sold here is for adults aged 18 and over, and nothing on this page is a health claim. If you are a non-smoker, vaping is not something you need to start.

Flavour profile: what Sour Blueberry tastes like

The lead flavour is blueberry, and it leans towards the jammy, cooked-fruit side of the spectrum rather than a crisp fresh-berry taste. On the inhale you can expect a sweet blueberry note with a slightly acidic tang at the front of the tongue. On the exhale the sour element lingers for a moment, then fades to a rounded, sweet berry aftertaste. The sourness is the feature that sets it apart from a standard blueberry liquid, and it is there to lift the flavour rather than to make your face pucker.

Sour is a subjective taste, so it helps to set expectations. Most people describe this style of liquid as noticeable but not harsh. If you find sour sweets too sharp, you may find the tang on the exhale stronger than you want, particularly at higher wattages. If you enjoy a tart edge, you will probably notice it on every puff without it becoming tiring.

Power settings change how the flavour reads, and it is worth experimenting for the first few tanks:

• Lower wattage (around 35 to 45W on a typical sub-ohm coil): Cooler vapour, more emphasis on the sweet blueberry, and a gentler sour note.
• Mid-range wattage (around 45 to 60W): A balanced profile where sweetness and tang are both clear. This is where most people settle.
• Higher wattage (60W and above, if your coil is rated for it): Warmer vapour, a stronger sour finish, and quicker liquid consumption. Some people find the flavour becomes less defined if the coil is pushed to its upper limit.

There is no menthol or ice listed in the name, so you should not expect a cooling sensation. If you want a chilled blueberry, you would look at an ice variant instead. The profile is a straightforward fruit candy flavour with a tart finish, which makes it an easy all-day option for people who prefer fruit to desserts, tobacco or menthol.

One practical note on flavour fatigue: sweet, fruity liquids can start to taste muted after a few days of exclusive use. If that happens, swapping to a different flavour for a day usually resets your palate, and changing the coil helps if the muting comes from coil build-up rather than your taste buds.

Performance and puff delivery with a 70VG shortfill

Because this is a high-VG liquid, it is built for dense vapour production. Vegetable glycerine (VG) produces thick, smooth vapour, while propylene glycol (PG) carries flavour and delivers the throat hit. A 70VG/30PG balance gives you generous clouds on a sub-ohm setup with a soft throat sensation, especially at 0mg to 3mg nicotine. If you want a sharper hit, you will need to raise the nicotine rather than rely on the base.

An e-liquid does not have a puff count in the way a disposable device does, because the number of puffs depends on your hardware, wattage, draw length and how often you vape. As a rough guide only, on a sub-ohm tank at 50 to 60W with draws of around three seconds, a 50ml bottle tends to work out at somewhere between 800 and 1,500 draws. On a lower-powered pod or tank, where each puff vaporises far less liquid, the same bottle can stretch to several thousand draws. Treat those numbers as estimates rather than guarantees, since coil resistance, airflow and puffing style all move the result.

What you can expect from the way it delivers:

• Vapour volume: High on sub-ohm kits. This is a cloud-friendly ratio, so expect noticeable vapour clouds on every draw.
• Throat hit: Light at 0mg, mild at 3mg, and firmer at 6mg. The VG-heavy base smooths out the hit compared with a 50/50 liquid.
• Flavour delivery: Good on mesh coils, which spread heat evenly across the wick. The sour element comes through more clearly when the coil is well primed and not overheated.
• Consistency: Stable from the first fill to the last, provided you shake the bottle well after adding any nicotine shots.

For anyone moving from a mouth-to-lung (MTL) pod device to a sub-ohm tank, the change in airflow and vapour density takes some getting used to. Start at a lower wattage than you think you need, take shorter draws, and let the coil build up gradually. A high-VG shortfill is less forgiving of an unprimed coil than a thin salt liquid, so patience on the first fill pays off.

Design, bottle and packaging

Shortfills are sold in a bottle larger than the liquid volume, and the Ohm Brew bottle follows that pattern. The extra space is deliberate: it is where a 10ml nicotine shot goes if you want to turn the 50ml of liquid into a roughly 3mg mix. A 50ml fill in a 60ml bottle leaves room for exactly one 10ml shot. Check the bottle size printed on your label, since the headroom decides how many shots you can add.

The bottle uses a narrow nozzle tip, which is what makes filling most tanks straightforward. It fits the top-fill ports on common sub-ohm tanks and the fill holes on most refillable pods, although very small pod fill ports can need a slow, steady squeeze. If a particular tank has an unusually narrow port, a fine-tipped refill bottle is an easy workaround.

Things worth checking on the bottle in your hands:

• Label information: Flavour name, VG/PG ratio, volume, batch code and best-before date should all be printed. Keep the batch code if you ever need to contact the retailer.
• Age warning: The 18+ marking is a legal requirement, not decoration. Vape products must be kept out of reach of children and pets.
• Cap and seal: A tamper-evident seal should be intact on arrival. If a bottle arrives open or leaking, photograph it and contact the shop straight away.
• Nicotine warnings: Once you add nicotine shots, the mixed bottle contains nicotine. Treat it that way and store it safely.

Storage matters more than most people expect. Keep the bottle in a cool, dark place away from direct sunlight and radiators, because heat and light degrade flavour over time and can darken the liquid. Wipe the nozzle after filling so residue does not collect around the thread.

On disposal, empty plastic bottles can usually go in household plastic recycling once rinsed and with the cap removed, but your council's rules are the final word, so check the local guidance. Batteries and devices are a different matter. Used vape batteries and old kits should never go in a normal bin or kerbside recycling, and should be taken to a battery or electrical drop-off point instead. Many supermarkets and council recycling centres have them.

Nicotine strength: how to choose and how to mix

This product is supplied as a shortfill at 0mg/ml nicotine. That gives you three choices: vape it at 0mg, add one nicotine shot to reach roughly 3mg/ml, or use a different shot strength to land somewhere nearby. In the UK, e-liquids containing nicotine are capped at 20mg/ml, and nicotine-containing bottles are capped at 10ml, which is why nicotine shots come in small 10ml bottles. Those same rules are why disposables are limited to 20mg/ml salts, and why shortfills sell the nicotine and the flavour separately.

The arithmetic is simple. A single 10ml shot added to 50ml of liquid gives 60ml in total, so the final strength is the shot strength multiplied by 10ml, divided by 60ml. Common examples:

• No shot: 0mg/ml
• One 10ml shot at 10mg/ml: about 1.7mg/ml
• One 10ml shot at 18mg/ml: 3mg/ml
• One 10ml shot at 20mg/ml: about 3.3mg/ml

If you want a higher strength than a single shot gives, you would need a bigger mixing bottle or a different product, because the standard shortfill bottle only has room for one shot. Going above 6mg/ml in a high-VG liquid also tends to produce a harsh throat hit on a sub-ohm tank, so people who need more nicotine often do better with a nicotine salt product on a low-power device rather than forcing a shortfill to do the job.

A sensible way to choose:

• 0mg: For people who vape out of habit or enjoyment and no longer need nicotine, or who have never smoked.
• 3mg: The common choice for sub-ohm vapers who are used to light to moderate nicotine intake.
• 6mg: A fit for some former smokers on restricted-draw tanks, though a nicotine salt device is often more comfortable at that level.

If you are using vaping to cut down or stop smoking, the NHS stop smoking service can help you pick a plan, and this page does not claim any product helps you quit. Non-smokers and under-18s should not use nicotine products. If you ever feel dizzy, sick or lightheaded after vaping, you have probably taken in too much nicotine, so put the device down, get some air and drink water.

Coils, mesh and hardware compatibility

A 70VG liquid wants a coil that can pull it in quickly. Thick liquid moves slowly through cotton, so a coil with large wicking holes, or a mesh coil with a wide surface area, keeps the wick fed and avoids dry hits. The usual pairing is a sub-ohm tank with a mesh coil, and that is the setup this liquid is aimed at.

Coil guidance by hardware type:

• Sub-ohm tanks with mesh coils (around 0.15 to 0.4 ohm): The natural match. Run them in the wattage range printed on the coil, typically 40 to 80W depending on the model. Mesh spreads heat evenly, which helps the sour edge come through without scorching the cotton.
• Sub-ohm tanks with standard round-wire coils (around 0.4 to 0.6 ohm): Also fine, usually at 25 to 45W. Lower power gives a gentler vapour and a longer-lasting coil.
• Refillable pods and MTL tanks (0.8 ohm and above): Check the maker's notes. Some are designed for high-VG liquids and some are not. A small wicking port plus thick liquid is the classic recipe for a dry hit, so only use 70VG here if the device lists support for it.
• Disposable-style devices: Not applicable. Disposables ship with their own pre-filled liquid and are not designed for refilling. Single-use vapes have also been banned for sale in Great Britain since 1 June 2025, which is a big part of why refillable kits matter.

Priming a new coil is the step people skip and regret. Drip a few drops straight onto the exposed cotton, fill the tank, then let it sit for five to ten minutes before you press the button. Do a few short, low-power draws first to finish the saturation. Firing a dry coil burns the cotton on the first draw, and no amount of later care repairs that taste.

Sweet and fruity liquids, including this one, usually shorten coil life a little because sugars and sweeteners caramelise on the coil surface. Expect one to two weeks from a coil under normal daily use, and replace it as soon as the flavour dulls or turns slightly burnt. Chain vaping, very high wattage and running the tank low all shorten coil life further.

Device batteries, wattage and charging

An e-liquid has no battery of its own, so charging is about the device you pair it with. Because this is a high-VG liquid made for sub-ohm hardware, the device matters more than usual: running a 0.2 ohm mesh coil at 55W takes real power, and a small battery will drain quickly.

As a very rough guide, a 1,500mAh built-in battery running at around 60W holds enough energy to vaporise somewhere in the region of 4 to 5ml of liquid per charge once efficiency losses are counted. That means a 50ml bottle works out at ten or more charges. Larger built-in batteries of 3,000mAh or more roughly double the time between charges, while removable 18650 cells give you the option to carry a spare. Treat those numbers as estimates, not promises, because wattage, coil resistance and puff length all change the result.

Practical charging and battery habits:

• Use the cable that came with the device. If you need a replacement, use a reputable cable and a standard USB charger rather than an unbranded fast charger.
• Do not charge under a pillow, on a bed or overnight while you sleep. Lithium cells fail rarely, but a charging device on soft furnishings is the typical set-up when they do.
• Inspect removable cells. If the wrap is torn or the cell is dented, do not use it. Carry spare cells in a plastic case, never loose in a pocket with keys or coins.
• Match the cell to the device. Sub-ohm devices need cells with a continuous discharge rating suited to the output you are running, so check the cell label.
• Stop using a hot, swollen or damaged battery. Take it to a battery drop-off point.

Recycling is straightforward in the UK. Supermarkets, council recycling centres and many electrical retailers have drop-off points for small batteries and electrical items, and old vape kits can go in the same places. Never put a vape battery in the general rubbish or the household recycling bin, because crushed lithium cells have caused fires in collection vehicles and waste sites.

Who Ohm Brew Sour Blueberry is for, and who should skip it

Every liquid suits some people and frustrates others. The point of this section is to help you decide quickly rather than find out after you have paid.

It is a good match if you:

• Use a sub-ohm tank or a refillable device that supports high-VG liquid
• Prefer fruit flavours to dessert, tobacco or menthol profiles
• Enjoy sour sweets or tart berries and want that tang in your vape
• Vape at 0mg to 3mg and like the flexibility of a shortfill
• Go through enough liquid that a 50ml bottle is more practical than several 10ml ones
• Like the option to adjust nicotine yourself by choosing your own shot strength

It is probably not the right pick if you:

• Need high nicotine. A shortfill with a single shot tops out near 3mg/ml. Heavy former smokers who need 10mg to 20mg usually find a nicotine salt product easier on the throat.
• Use a small, low-power pod kit. Thick 70VG liquid can wick poorly in tiny pod coils and cause dry hits or weak flavour. Check compatibility first.
• Want a cooling or menthol finish. This is a warm fruit profile with a sour twist, not an ice flavour.
• Dislike sour or acidic tastes. The tang is the point of the flavour. If you avoid sour sweets, choose a plain blueberry.
• Prefer ready-to-go disposables. Those are no longer sold in Great Britain, and a refillable kit is a different way of vaping that takes a little setup.

It is not for anyone under 18, and it is not a product for non-smokers to take up. If you are pregnant or have a medical condition, speak to a healthcare professional before using any nicotine product. Nothing here is medical advice, and there is no suggestion that vaping is risk-free, only that for adult smokers it carries a different risk profile from smoking.

How to use it: mixing, resting and filling

Setting up a shortfill takes a few minutes the first time, then becomes routine. Follow these steps in order.

• Check the seal and label. Make sure the bottle is intact and the batch code is legible. Wash your hands before handling.
• Decide on your nicotine. If you are vaping at 0mg, skip to the shaking step. If you want about 3mg/ml, you need one 10ml nicotine shot at 18mg/ml, which is sold separately.
• Open the shortfill and add the shot. Remove the nozzle, pour the shot in carefully, and refit the nozzle and cap firmly. Wipe up any spills straight away, since nicotine liquid can be absorbed through the skin.
• Shake thoroughly. Give the bottle a firm shake for around 30 seconds so the shot and the flavoured liquid blend evenly. Shake again before every refill for the first few uses.
• Let it rest. Five to ten minutes is the minimum, and a few hours is better. Resting lets the bubbles clear and the flavours settle.
• Fill your tank or pod. Tilt the tank, aim the nozzle at the side of the fill port and let the liquid run down the wall. Do not flood the central airflow tube, and do not overfill past the maximum line.
• Prime the coil. Leave the filled tank to stand for five to ten minutes, then take a few low-power draws before ramping up.
• Start low and adjust. Begin at the lower end of the coil's recommended wattage and increase in small steps until the flavour and vapour feel right.

A few extra habits make life easier. Keep the airflow ring set to a comfortable middle position until you know what suits you. Take draws of around two to four seconds rather than long, hard pulls. Rinse the tank with warm water and dry it fully when you change flavours, because leftover liquid causes ghosting, where the old flavour bleeds into the new one.

Keep nicotine-containing bottles out of reach of children and pets at all times. If the liquid gets on your skin, wash it off with soap and water. If anyone swallows it, seek medical help immediately.

Troubleshooting common problems

Most vape problems come down to the coil, the wicking or the power setting rather than the liquid. These are the issues people ask about most with high-VG shortfills, with the usual cause and fix.

• Dry or burnt taste on the first draws. The coil was not primed enough. Drip liquid onto the cotton, wait ten minutes after filling, and begin at low wattage. If the burnt taste stays after a few tanks, replace the coil.
• Flavour seems weak or muted. Usually coil build-up. Swap the coil, rinse the tank and try again. Flavour fatigue is another cause, so try a different flavour for a day.
• Gurgling or spitting. Condensation in the airflow path, or an overfilled tank. Wipe the airflow channel, avoid filling past the maximum line and make sure the coil is seated properly.
• Leaking from the tank. A poorly seated coil, a worn seal, an overfilled tank or pressure changes can all cause this. Check the coil is screwed in firmly and the O-rings are clean and intact, and avoid carrying the tank full on flights or in hot cars.
• Throat hit too harsh. Lower the wattage, open the airflow a little or drop the nicotine strength. If you added a shot, make sure it is well mixed, because an unmixed pocket of shot feels strong.
• Liquid too thick to wick. If a pod is struggling, warm the bottle in your hands for a minute, or switch to a tank designed for high-VG. A thin 50/50 liquid is often a better match for small pod kits.
• Sourness feels too strong. Drop the wattage by 5W or so, since lower power reduces the tang. Or mix with a plain blueberry if you have one.
• Sourness feels too weak. Raise the wattage slightly and make sure the coil is fresh, since an old coil flattens the sharper notes.
• Sticky residue around the tank and bottle. Normal with sweet VG-heavy liquids. Wipe with a damp cloth and keep the thread on the bottle clean.

If you have tried these fixes and something still seems wrong, contact the shop with the batch code from the bottle. If a bottle arrives damaged or leaking, keep it and take photos before you throw anything away.

Value for money and how long 50ml lasts

The case for a 50ml shortfill is cost per millilitre. A 10ml nicotine salt bottle costs less up front but works out noticeably more expensive per ml over a month, and heavy users pay for the convenience many times over. Check the current price on this page, since it can change with promotions, and compare it against the cost of the equivalent volume in 10ml bottles. You will also want to factor in the small extra cost of any nicotine shots you add.

Duration depends on how you vape, so here are some worked examples. They assume you fill the whole 50ml bottle with no shot added, so adding a shot takes it to 60ml and stretches it by about a fifth:

• Light use, around 2ml a day: A 50ml bottle lasts around 25 days, or 30 days with a shot.
• Moderate use, around 4ml a day: Around 12 to 13 days, or 15 days with a shot.
• Heavy sub-ohm use, around 6 to 8ml a day: Around 6 to 8 days, or 7 to 10 days with a shot.

Remember the other running costs. Mesh coils are usually sold in packs of five and each one lasts around one to two weeks. Sweet fruit liquids tend to land on the shorter side of that range. If you get through a bottle in a week, you will probably replace a coil in the same time, so budget for both.

Where the value is strongest: if you already own a compatible sub-ohm kit, vape at 0mg to 3mg, and use enough liquid that bulk buying pays off. Where it is weaker: if you vape lightly, you may not finish 50ml before the flavour starts to feel stale. In that case a smaller bottle might be a better choice. Unopened bottles keep well for many months in a cool place, but once mixed with a nicotine shot, aim to use the bottle within a few months for the cleanest taste.

Value is also about not wasting money on the wrong product. Check that your device handles 70VG before ordering, and pick a nicotine strength you will actually use. A cheap bottle that causes dry hits or does not suit your kit is poor value regardless of the price.

Honest comparisons with other options

No single liquid suits everyone, so here is a fair look at how this one stacks up against the alternatives you are probably weighing.

Against a plain sweet blueberry shortfill. A standard blueberry is usually smoother and more forgiving, and some people vape it all day without tiring. Sour Blueberry gives you more contrast and a more distinctive finish, but the tang is not for everyone. If you are unsure, a plain blueberry is the safer starting point.

Against an ice or menthol blueberry. Cooling variants suit warm weather and people who like a crisp finish. This liquid does not claim any cooling, so if you want ice, look elsewhere.

Against other established UK shortfill brands. Brands such as IVG, Doozy Vape Co and Dinner Lady all sell 50ml high-VG shortfills in fruit flavours, with similar prices and similar hardware needs. Differences come down to the recipe and your palate, not to a hard technical gap. Some competitors offer a wider range of dessert and drinks flavours or more complex layered profiles. Ohm Brew's strengths are an approachable price and a focus on fruit-forward flavours, and the main trade-off is that it is not aiming for the layered complexity of premium craft liquids. Check recent reviews and the batch label rather than relying on brand reputation alone.

Against nicotine salt 10ml bottles. Salts suit low-power pod kits and people who need higher nicotine, and the 10ml format is convenient for carrying. They cost more per ml and give less vapour. Shortfills suit sub-ohm tanks, bigger clouds and lower nicotine, and they cost less per ml but need a bit more setup.

Against disposables. Disposable vapes can no longer be sold in Great Britain, so this is no longer a like-for-like decision for most buyers. A refillable kit costs more on day one, uses replaceable parts, and produces far less waste, since you recycle a bottle rather than a whole device with a lithium battery inside.

The bottom line: choose this if you want a tangy fruit shortfill for a compatible tank and you are comfortable mixing your own nicotine. Choose something else if you need high nicotine, a small pod kit, an ice finish or the sort of complexity you only find in premium liquids.
