Ohm Brew Badass Blend The Black 50ml: Overview

Ohm Brew Badass Blend 50ml The Black is a nicotine-free shortfill e-liquid from the Ohm brand, made for UK vapers who use refillable sub-ohm tanks and higher-wattage pod systems. A shortfill is simply a bottle that is deliberately left short of its full capacity. This one holds 50ml of flavoured liquid at 0mg nicotine inside a 60ml bottle, which leaves room to add a single 10ml nicotine shot if you want to vape at around 3mg/ml. If you do not use nicotine, you can vape it exactly as it comes.

The Badass Blend range is Ohm's colour-coded line of 50ml shortfills, and The Black is the darker-named entry in that family. Ohm Brew sits in the value-to-mid bracket of the UK shortfill market, so the pitch is straightforward: a large bottle, a bold flavour concept and a price that makes sense for people who vape all day rather than occasionally.

This guide covers what you actually need to know before buying: the specification, how the flavour is likely to behave, which devices suit it, how to mix and steep it, how to fix the usual problems, and how it compares with other 50ml ranges. It is written for UK buyers, so the legal and practical points (the 20mg/ml nicotine cap, the 10ml limit on nicotine bottles, the 18+ age restriction and recycling) are covered where they matter.

One note on how we describe flavour. The bottle label and the manufacturer's own listing are the authority on the exact flavour notes. The flavour section below describes how a dark, dense profile of this type typically behaves in a tank and how to get a good result from it, rather than claiming a tasting note that cannot be verified from the label alone.

• Format: 50ml shortfill in a 60ml bottle
• Nicotine as supplied: 0mg/ml
• Room for: one 10ml nicotine shot (about 3mg/ml once mixed)
• Best suited to: sub-ohm tanks and high-power refillable pods
• Age restriction: 18+ only

Key specifications at a glance

Before getting into flavour and performance, it helps to be clear on the numbers. The list below sets out what you are buying. Where a figure is typical of the shortfill format rather than printed on this specific bottle, we say so, and you should always check the label on the bottle you receive.

• Brand and range: Ohm, Ohm Brew Badass Blend
• Flavour name: The Black
• Liquid volume: 50ml
• Bottle size: 60ml, the usual UK shortfill format, with headroom for one nicotine shot
• Nicotine strength as supplied: 0mg/ml
• VG/PG ratio: shortfills in this class are normally high-VG, commonly around 70VG/30PG. Confirm the ratio printed on your bottle.
• Intended hardware: sub-ohm tanks (roughly 0.15 to 0.6 ohm coils) and refillable pods rated for thick liquid
• Typical power range: about 40W to 80W depending on coil, with the coil manufacturer's printed range as your guide
• Bottle features: plastic bottle with a narrow nozzle and a child-resistant, tamper-evident cap

The nicotine arithmetic is simple, and it is worth understanding so you can pick the strength you want. When you add a nicotine shot, you divide the total nicotine in the shot by the total volume of the finished bottle. A 10ml shot at 18mg/ml contains 180mg of nicotine. Add it to 50ml of liquid and the total volume becomes 60ml, so the result is 180 divided by 60, which is 3mg/ml. A 10ml shot at 20mg/ml gives about 3.3mg/ml, and a 10ml shot at 10mg/ml gives about 1.7mg/ml.

UK rules shape the format. Nicotine-containing e-liquid cannot be sold in bottles larger than 10ml, and the maximum nicotine strength is 20mg/ml (2%). That is why shortfills are sold at 0mg and nicotine comes separately in 10ml shots or 10ml nic salt bottles. The 20mg/ml cap is also the figure you will see attached to disposable-style products, although disposable vapes are no longer sold across Great Britain, which pushes more people toward refillable setups like the one this liquid is designed for.

Flavour profile: what to expect from The Black

The name The Black signals a darker, denser style of profile than the lighter, brighter names you will find elsewhere in a shortfill range. In e-liquid, black-themed flavours tend to mean deep dark-fruit notes, a layered sweetness rather than a sharp one, and sometimes a cooling edge on the exhale. The exact tasting notes are printed on the bottle and listed by the manufacturer, so treat the following as guidance on how a profile of this kind behaves rather than a substitute for the label.

Dark, dense flavours usually deliver most of their character in the middle of the inhale. You get the body of the flavour first, then a rounded finish that lingers slightly on the exhale. Because the profile leans bold rather than delicate, it tends to hold up well in a cooler vape, which matters if you run your tank at the lower end of its wattage range.

High-VG liquids generally taste a little softer and smoother than high-PG liquids at the same flavouring level, because VG carries flavour less sharply. If you have come from a 50/50 liquid, expect the throat hit to feel gentler and the flavour to feel rounder and slightly sweeter. That is the VG at work rather than a fault in the liquid.

A few practical points that affect how the flavour comes across in your own setup:

• Temperature: warmer vapes bring out sweetness and intensity but can flatten the finer notes. Cooler vapes keep the layers separate and are kinder to the coil.
• Airflow: a tighter airflow concentrates flavour. A wide-open airflow gives bigger clouds but dilutes the taste, so open it up gradually until you find the balance.
• Fresh coils: a new coil usually tastes its best in the first few days, and you may notice the flavour thinning as the coil ages.
• Nicotine: adding a nicotine shot slightly sharpens the throat hit and can make the flavour feel a touch drier. A nic-free vape tastes smoother and sweeter.

If you want a second opinion on flavour intensity, the sensible approach is to buy one bottle, give it a few days across a couple of coils, and judge it on a settled setup rather than the first pull from a fresh bottle.

Performance and vapour delivery

Performance with a shortfill is mostly a question of matching the liquid to the hardware. A 50ml high-VG liquid is built to produce thick, dense vapour, and it does that best in a sub-ohm tank with a coil that can heat it quickly and wick it freely. In that kind of setup you can expect a smooth, warm inhale, generous vapour and a throat hit that is mild at 0mg and noticeable but not harsh once you add a 3mg shot.

It is worth being clear about what a shortfill does not do. Unlike a disposable device that advertises a puff count, a bottle of liquid has no fixed number of puffs. How many you get depends on your device, your coil resistance, your wattage and the length of your draws. As a rough guide, a 50ml bottle in a sub-ohm tank at typical power can last one heavy vaper a little over a week, while a lighter user may stretch it to two or three weeks. A tank consumes roughly 2ml to 5ml per day for most sub-ohm users, though a 70W-plus setup with long pulls will use more.

Wicking is the point where high-VG liquids can let you down. Thick liquid needs coils with large wicking ports and cotton that can keep up. If your coil is too small, you can get dry hits during longer draws. Keeping your tank at least a third full and giving the coil a few minutes to soak before the first pull both help.

• Vapour production: dense and warm in sub-ohm setups, noticeably less in low-power pods
• Throat hit: smooth at 0mg, moderate at around 3mg, and stronger if you add more nicotine in a larger mixing bottle
• Flavour consistency: steady while the coil is fresh, tapering as the cotton and mesh age
• Best draw style: longer, lower-resistance direct-to-lung inhales rather than tight mouth-to-lung draws

For consistency, keep an eye on how the first few pulls of each tank fill taste. If the flavour drops away quickly, you are probably running too much power for the coil, or the coil is near the end of its life. Dropping the wattage by 5W is usually the quickest test.

Bottle design and build quality

With a liquid, the build quality you are judging is the bottle and the closure, not a device. Ohm Brew uses the standard shortfill packaging format found across UK brands: a 60ml plastic bottle with a narrow nozzle for filling tanks and a child-resistant, tamper-evident cap. The 60ml size matters because it is what leaves room for one 10ml nicotine shot without overfilling.

The narrow nozzle is practical rather than decorative. It lets you place the tip into most tank fill ports without spilling, and it controls the flow so you do not flood the airflow channel. Soft plastic bottles of this type can be squeezed gently to dispense, and they will not shatter if dropped in a bag. The trade-off is that plastic can collect a little static and dust over time, so it is worth wiping the nozzle before use.

The label carries the information UK rules require, including the product name, the nicotine strength (0mg for the shortfill), the ingredients list and the health warnings. It is worth reading the label for the VG/PG ratio and the batch details, because the batch number is what you quote if you ever need to raise a query about a bottle.

• Closure: child-resistant cap with a tamper-evident seal, which should be intact when your order arrives
• Material: plastic bottle with a narrow dropper nozzle
• Capacity: 60ml total, 50ml of liquid, so there is empty headroom by design
• Storage: keep it upright, tightly capped, away from direct sunlight and heat

A few handling tips that extend the life of the liquid. Wipe the nozzle after each fill so residue does not build up and cause the cap to stick. Do not store the bottle in a hot car or on a sunny windowsill, since heat degrades flavour and can darken the liquid. Keep it out of reach of children and pets at all times, because even nicotine-free liquid is not safe to swallow.

For recycling, rinse nothing into a sink and do not decant leftovers into drains. Once a bottle is completely empty, check your local council's guidance on small plastics, and take any vape hardware to a household waste recycling centre or a retailer drop-off point so batteries are handled correctly.

Nicotine strength guidance

The Black arrives at 0mg, so the first decision is whether to add nicotine at all. The shortfill format gives you three realistic options, and which one suits you depends on how much nicotine you currently use and what you are trying to achieve.

• Leave it at 0mg: best for people who have finished with nicotine or who vape purely for the flavour and the habit. This is the smoothest option.
• Add one 18mg or 20mg shot (about 3mg to 3.3mg/ml): the standard UK approach for sub-ohm users. It is a modest strength that suits people who vape frequently throughout the day.
• Add a 10mg shot (about 1.7mg/ml): a gentler middle ground for people stepping down.

Higher strengths such as 6mg/ml need a bigger mixing bottle, because two 10ml shots plus 50ml of liquid come to 70ml, which will not fit in the 60ml bottle. If you want that, pour the contents into a larger empty bottle, or use a 70ml-or-larger shortfill-friendly container. Do the sum carefully: two 18mg shots in 70ml gives about 5.1mg/ml, not 6mg/ml.

Nicotine strength should also be matched to the device. Sub-ohm vaping delivers a lot of vapour per puff, so the same nicotine concentration delivers considerably more nicotine per session than a small, restricted pod. That is why UK sub-ohm users typically sit at 0mg to 3mg, while mouth-to-lung users go higher with nicotine salts at 10mg to 20mg. If you are moving from cigarettes or from a nic-salt pod, start with 3mg and adjust over a week rather than guessing high.

Two sensible rules apply. First, if the throat hit feels harsh or you feel lightheaded or nauseous, you are using too much nicotine for the way you vape, so step down. Second, if you find yourself reaching for a cigarette or chain vaping to feel satisfied, you may need slightly more. Neither extreme is a sign of a bad liquid. It is simply about finding the right strength for your habits.

Remember that nicotine is addictive. If you do not currently use nicotine products, a nicotine-free liquid is the right choice, and the product is not intended for non-smokers or anyone under 18.

Coil and mesh technology: choosing the right tank

Because The Black is a liquid rather than a device, the coil is the part of your own hardware that decides how good the experience is. High-VG shortfills are designed around coils with generous wicking and enough surface area to vaporise thick liquid evenly. That points to mesh coils and low-resistance round-wire coils in sub-ohm tanks.

Mesh coils use a flat sheet of metal mesh, usually stainless steel or a nickel-iron alloy, pressed against cotton. The large surface area heats quickly and evenly, which tends to give strong flavour, quick ramp-up and dense vapour with high-VG liquid. They are the usual choice at 0.15 to 0.3 ohm and 50W to 80W. The trade-off is that they can use more liquid and may wear faster at the top of their wattage range.

Round-wire coils in the 0.3 to 0.6 ohm range are a lower-power alternative. They are suited to 30W to 50W, use less liquid, and tend to last a little longer, with a flavour that some vapers find slightly cleaner on delicate profiles. For a bold, dense flavour like The Black, a mesh coil in the 0.2 to 0.4 ohm range is a sensible starting point.

• 0.15 to 0.3 ohm mesh: maximum vapour, higher power, direct-to-lung
• 0.3 to 0.6 ohm mesh or round wire: balanced flavour and vapour, moderate power, good for daily use
• 0.8 to 1.0 ohm pod coils: only suitable if the pod is rated for high-VG liquid, otherwise wicking will struggle

Priming matters more with thick liquid. Before the first pull on a new coil, drip a few drops of liquid directly onto the cotton through the wicking holes, fill the tank, then wait five to ten minutes. Skipping that step is the most common cause of a burnt first tank.

Keep an eye on coil life. A coil that is running correctly with a high-VG liquid typically lasts about one to two weeks for an average user, with sweeter and more viscous liquids tending to wear coils a little faster. If flavour turns muddy, the vapour thins, or you notice a slight burnt edge, change the coil rather than trying to power through it.

Finally, check the tank's maximum liquid capacity. UK tanks are sold in 2ml format to meet sale rules, with extension glass supplied in the box for larger capacities. A larger tank means fewer refills, which suits a 50ml bottle well.

Battery and charging for your device

The Black needs a battery that can drive a sub-ohm coil, so the practical question is what your mod or kit needs in terms of power and charging. This section is about the hardware you will pair the liquid with, because battery performance decides how long a day's vaping lasts.

Sub-ohm kits are generally powered by one or two replaceable 18650 or 21700 lithium-ion cells, or by a built-in battery of about 1,500mAh to 3,000mAh in compact kits. A 21700 cell is typically around 4,000mAh to 5,000mAh, and an 18650 is typically around 2,500mAh to 3,500mAh. As a rough guide, a single 3,000mAh cell at 50W will give a moderate vaper a good part of a day, while a heavy user at 80W will often need a spare cell or a mid-day top-up.

• Built-in battery kits: charge over USB-C, usually at 1A to 2A, taking roughly one to two hours for a compact pod kit
• Replaceable-cell mods: remove the cells and charge them in an external charger, or charge in the device where the manufacturer allows it
• High-drain cells: use only cells from reputable makers with a continuous discharge rating that matches your device

Battery safety is not optional, and it matters more at the high currents a sub-ohm vape draws. Use the charger supplied with the device or one of equal quality. Do not charge unattended overnight, do not carry loose cells in a pocket with coins or keys, and do not use a cell with a torn wrap. Stop using any battery that is swelling, hissing, or getting unusually hot.

For UK recycling, spent batteries and vape hardware are classed as waste electrical and electronic equipment. They should never go in household bins. Take them to a household waste recycling centre, or to a retailer drop-off point, or use the recycling locator run by the Recycle Your Electricals campaign. This is especially important for lithium cells because fires in refuse lorries and recycling plants are a real hazard.

If your device shows a short-circuit, low-resistance or check-atomiser warning when you try a new coil, seat the coil more firmly, check the tank threading is clean and dry, and try again. Persistent faults mean it is time to stop and check the device rather than increase the power.

Who The Black is for, and who should skip it

A shortfill is not the right product for everyone. Being straight about that saves you money and frustration, so here is who is likely to be happy with this bottle and who should look elsewhere.

Good fit for:

• Existing adult vapers who already own a sub-ohm tank or a high-power refillable pod and want a large bottle at a sensible cost
• People who enjoy bolder, denser flavour profiles and prefer a smooth, high-VG vape
• Vapers stepping down from stronger nicotine who like the flexibility to mix 0mg, 1.7mg or 3mg
• People who vape heavily through the day and get through a bottle in a week or two, so the volume makes economic sense

Not a great fit for:

• Anyone under 18. It is illegal to sell or supply vaping products to under-18s in the UK, and we do not knowingly do so.
• Non-smokers who have never used nicotine. Vaping is intended as an alternative for adult smokers, not as a starting habit.
• Pod-system users with small 0.8 to 1.2 ohm coils. High-VG liquid will wick slowly in those and may cause dry hits or leaks. If you use a small pod, consider a nicotine salt liquid in a 10ml bottle instead.
• Anyone looking for a tight, cigarette-like mouth-to-lung experience. A high-VG shortfill is built for airy, direct-to-lung pulls.
• People who want a grab-and-go device with nothing to fill or maintain. A shortfill needs a tank, coils and a little routine.

It is also worth being realistic about learning curve. If you are new to refillable vaping, you will need to learn how to prime a coil, fill a tank, mix a nicotine shot and change coils. None of these steps is hard, but there are a few to learn. The how-to section below walks through each one, and the troubleshooting section covers the usual early mistakes.

Finally, if you are pregnant, have a heart condition, or are taking medication that interacts with nicotine, talk to your GP or pharmacist before using any nicotine product. Local stop smoking services in the UK can offer support and advice on moving away from cigarettes entirely.

How to use: mixing, steeping and filling

Getting a good result from a shortfill comes down to following a handful of steps in order. None are complicated, but skipping any of them is the usual reason for a poor first impression.

Step one: decide on nicotine. If you want 0mg, skip to filling. If you want about 3mg/ml, you need one 10ml nicotine shot at 18mg/ml (or 20mg/ml for around 3.3mg/ml). Buy it separately; it is not included.

Step two: add the shot. Unscrew the cap of the 60ml bottle and pour or squeeze the nicotine shot straight in. Do not overfill. The headroom is calculated for exactly one 10ml shot. Wipe up any spillage straight away.

Step three: shake. Close the cap firmly and shake for 30 to 60 seconds so the nicotine disperses evenly through the thicker VG. Shake again once or twice over the next few hours.

Step four: steep. Many vapers vape straight away, which is fine. Leaving the bottle for a day or two with the cap slightly loosened for a few minutes (to let air out) and then tightened can smooth the flavour and let the mix settle. Fruit and dessert profiles often benefit from a short steep, while heavier profiles settle more slowly.

Step five: fill the tank. Remove the tank's top cap, tilt the tank slightly, place the nozzle against the inside wall and fill slowly without covering the central airflow tube. Fill to just below the maximum line. Replace the top cap and allow five to ten minutes for the cotton to soak.

Step six: set your power. Start at the lower end of the coil's printed wattage range and increase in 2W to 5W steps until the flavour and warmth feel right. High-VG liquids taste best at the lower and middle part of the range.

• Priming: always prime a new coil before the first pull
• Taking draws: use slow, steady pulls of two to four seconds and avoid chain vaping, which does not give the cotton time to re-wet
• Topping up: refill before the tank is a third full to avoid dry hits
• Cleaning: rinse the tank and drip tip with warm water between flavours and let it dry fully before refilling

Troubleshooting common problems

Most problems with shortfill liquids come from the hardware or the routine, not the liquid itself. Here are the issues vapers meet most often with a high-VG bottle and how to fix them.

• Burnt or acrid taste: usually a dry hit from an unprimed or worn coil, or too much power. Drop the wattage by 5W to 10W, make sure the tank is more than a third full, and replace the coil if the taste does not clear.
• Weak or flat flavour: a tired coil, a tank run too warm, or vaper's tongue (temporary taste fatigue). Change the coil, lower the power, and try a different flavour or plain water for a day to reset.
• Gurgling or spitting: too much condensation in the airflow, or an overfilled tank. Wipe the airflow, make sure you did not overfill, and check the coil is seated correctly.
• Leaking from the tank: usually a loose top cap, a worn silicone seal, or the tank being overfilled. Reassemble carefully, check the seals, and fill below the max line.
• Leaking from the bottle nozzle: squeezing too hard, or the cap not being fully tightened. Wipe the nozzle clean and store the bottle upright.
• Dry hits on long pulls: the cotton cannot keep up with a thick liquid. Shorten draws, allow a few seconds between puffs, or move to a coil with larger wicking ports.
• Coil dies within days: sweet or dark liquids can gunk coils faster. Reduce wattage, clean the tank, and avoid chain vaping.
• Nicotine feels too strong: you probably added the shot to a bottle that was not full, which concentrates the nicotine. Check the maths, or dilute with 0mg liquid.
• Liquid looks darker over time: normal ageing from air and light. Store in a cool, dark place and tighten the cap.

If the problem persists after you have swapped the coil and reset the power, check whether the tank itself is the issue. Cracked glass, a warped seal or a damaged thread will cause persistent leaks regardless of the liquid. Trying the same bottle in a different tank is a quick way to isolate whether the liquid or the device is responsible.

If you receive a bottle that arrives leaking, with a broken seal or with a label that does not match your order, do not use it. Take photos, keep the packaging and the batch number, and contact us. That is the quickest route to a replacement or refund.

Value for money and how it compares

Value in a shortfill is a mix of price per millilitre, flavour quality and how long a bottle lasts in your setup. A 50ml bottle gives you a lot of liquid per pound compared with buying 10ml nicotine salt bottles, and a heavy daily vaper can save a meaningful amount over a month. Check the current price on this page, since pricing changes with offers and multi-buy deals.

Ohm Brew sits in the accessible bracket of the UK 50ml market. That puts it in the same general territory as other mainstream shortfill ranges. It is fair to say that premium-positioned brands often spend more on flavour development, and their liquids can taste more refined or more intricate. Budget-positioned brands often win on price and volume. Ohm Brew aims for the middle: bold, simple profiles at a sensible cost.

Here is an honest read on how it stacks up against alternatives.

• Against dessert-led premium ranges: brands such as Dinner Lady and similar specialists put more emphasis on complex, layered desserts. If you want that kind of detail, they may suit you better, though at a higher price per bottle.
• Against other mainstream 50ml ranges: brands like Vampire Vape and Doozy Vape offer wider catalogues and long track records. The choice between them and Ohm Brew often comes down to which individual flavour you prefer rather than a clear overall gap.
• Against 10ml nic salt bottles: nic salts suit pods and tighter draws. They cost more per millilitre and are not designed for sub-ohm tanks, so the two do different jobs rather than competing.
• Against disposables: disposable vapes are no longer sold across Great Britain. A refillable setup costs more upfront for the kit, but a bottle of liquid is considerably cheaper per day of vaping, and it creates less electronic waste.

The honest trade-offs are these. You need a compatible tank and a routine for coils and charging. A shortfill needs nicotine added separately. And flavour is subjective, so the best way to judge value is to compare the cost per week of vaping rather than the sticker price alone.

If you vape through a bottle in about two weeks, a 50ml shortfill typically works out cheaper than most alternatives per day. If you only vape occasionally, a 10ml bottle may be easier to finish before the flavour starts to age.
