Ohm Brew Badass Blend Groovy Grapefruit 50ml: overview

Ohm Brew Badass Blend Groovy Grapefruit is a 50ml shortfill e-liquid built around one clear idea: grapefruit that stays recognisable from the first pull to the last, instead of fading into a generic citrus candy. It sits in the Badass Blend line from Ohm, a range of fruit-led shortfills aimed at UK vapers who use sub-ohm tanks, mesh-coil pod kits or adjustable mods and want a big bottle of nicotine-free liquid that they can vape as it is or bring up to a strength of their own choosing.

This page covers what the liquid tastes like, how it behaves in different hardware, how to add nicotine safely, what to do when something goes wrong, and how it compares with the alternatives you are probably weighing up. Everything is written from a UK point of view, so when we mention nicotine caps, bottle limits or recycling, we mean the UK rules and the UK drop-off options.

The key facts at a glance:

• Product: Ohm Brew Badass Blend, Groovy Grapefruit flavour
• Format: 50ml of liquid in a 60ml bottle, supplied at 0mg/ml nicotine, with space for one 10ml nicotine shot
• Style: fruit-forward citrus with a juicy, sweet-and-sour lead
• Base: shortfills in this category are normally high-VG, around 70VG/30PG, which suits sub-ohm and low-resistance hardware. Always confirm the exact split on the printed label of your bottle
• Nicotine: none in the bottle. One 10ml shot of 18mg/ml takes the full 60ml to roughly 3mg/ml
• Age restriction: 18+ only

A 50ml shortfill is a different purchase from a disposable or a small nic salt bottle. You need a refillable device, you need to be comfortable pouring liquid into a tank, and in return you get far more liquid per pound. For anyone who has been going through disposables and wants a flavour with some character that costs less over a month, a bottle like this is one of the more practical routes. For anyone who wants nothing to fill, nothing to mix and nothing to clean, it is the wrong format, and we say so plainly further down the page.

Flavour profile: what Groovy Grapefruit actually tastes like

Grapefruit is a harder flavour to get right in a vape than most fruits. The real thing has three parts that pull against each other: sweet juice, sharp acidity and a faint bitterness from the pith. A flavour house that leans too far on the sweetness gives you something closer to a fizzy orange sweet. Lean too far on the acidity and it tastes like a sour lemon sherbet. Groovy Grapefruit is designed to keep all three in play, with the juice and tang up front and a slightly dry, bittersweet finish on the exhale that tells you it is grapefruit and not some other citrus.

Here is how the flavour tends to unfold, based on the way citrus profiles of this type behave in a high-VG base:

• Inhale: a bright, juicy citrus hit that reads as ripe grapefruit rather than orange or lemon. There is a gentle sweetness to take the edge off the sourness.
• Mid-draw: the tang fills out. This is where the acidity is most noticeable, and where you will tell whether you like the profile or not.
• Exhale: a lighter, drier, faintly bitter note from the pith, and a clean finish that does not coat the mouth with sugar.

That clean finish is one of the practical reasons people pick citrus flavours for a daily vape. Heavy custards, thick desserts and syrupy candy profiles can leave a film on the tongue and make your palate tired after a few hours, which many vapers call vaper's tongue. Citrus is generally easier to live with across a whole day because the acidity keeps resetting your taste buds.

Wattage changes the picture noticeably. At the low end of your coil's range the flavour is cooler, sharper and more acidic, with the tang doing most of the work. As you increase power, the liquid warms, the sweetness rounds out and the bitterness of the pith becomes a little more obvious. If you find it too sour, turn the power up in small steps. If it tastes too sweet or cloying, turn it down.

One honest caveat: flavour is personal, and descriptions like this are a guide rather than a guarantee. If you have never vaped a grapefruit profile, expect something tart and slightly dry rather than a sweet fruit punch. If you want something rich and sugary, a berry or candy blend from the same range will suit you better.

Performance, vapour production and throat hit

Because this is a high-VG shortfill, the performance is defined by the base as much as the flavour. Vegetable glycerine produces thick, dense vapour and a soft, rounded throat sensation, while the smaller propylene glycol share carries the flavour and gives a little bite. In the usual 70VG/30PG region, you can expect plenty of visible vapour from a sub-ohm tank or mesh coil, a smooth draw, and flavour that comes through well when the coil is the right match.

What you can expect in practice:

• Vapour: dense and generous at 40W and above on a sub-ohm coil. More modest, but still fuller than a disposable, on a 0.6 to 0.8 ohm mesh pod coil at 15W to 25W.
• Throat hit at 0mg: very soft. Citrus acidity gives a tingle on the tongue, but there is very little scratch at the back of the throat.
• Throat hit at around 3mg/ml: light to moderate. This is the strength most people reach with one 10ml shot, and it is a comfortable level for direct-to-lung style vaping.
• Flavour intensity: noticeable from the first puff on a fresh coil, and steady across the tank. Citrus flavours do fade faster than dessert flavours as a coil ages, so a dulling taste is usually a signal to change the coil before it is a signal to change the liquid.

It is worth being straightforward about the trade-off between cloud and flavour. Pushing the power high on a big sub-ohm coil gives you the most vapour, but flavour tends to peak in the lower-to-middle part of the coil's rated range, and it can turn flat or slightly harsh at the top. Most vapers find a sweet spot around the middle of the wattage printed on the coil. With a fruit juice like this one you will usually be happier at a slightly cooler setting than you would run a dessert flavour.

Consumption is the other half of performance. A rough guide: light users on a pod kit get through 2ml to 3ml a day, typical sub-ohm users 4ml to 6ml, and heavy users on high-wattage devices 8ml or more. At those rates a 50ml bottle lasts anywhere from about a week to well over two weeks. For comparison, 50ml is the same volume of liquid as 25 refills of a standard 2ml disposable tank, which is the main reason a shortfill costs less per millilitre.

Airflow settings matter more than people think. A fully open airflow gives cooler, airier vapour and thinner flavour, while a tighter setting concentrates the taste and warms the vapour. Citrus flavours often come through best with the airflow half to three-quarters open, but try it on your own tank before settling.

Bottle, packaging and build quality

A 50ml shortfill is not a design object, and the sensible thing to judge is whether the packaging does its job: keeps the liquid sealed, is easy to fill from, and carries the information UK law requires. The standard format is a soft plastic 60ml bottle with a narrow nozzle tip, designed to slide into a tank's filling port without spilling, and a closure that is tamper-evident and child-resistant. Soft plastic matters because you can squeeze the bottle gently to control the flow, and because it is far less likely to crack than a rigid bottle if it gets dropped.

Things worth checking when your bottle arrives:

• Seal and cap: the tamper-evident ring should be intact and the cap should turn firmly. If the ring is broken or liquid has leaked inside the packaging, contact the shop before using it.
• Label: it should show the product name, volume, nicotine content (0mg/ml), ingredients, batch information and the required warnings. UK-sold e-liquids must carry an 18+ restriction and health warnings where nicotine is present.
• Nozzle: look for a clean, unblocked tip. A thin nozzle is what makes filling a small pod port possible, but it can also clog with dried liquid, which we cover in the troubleshooting section.
• Liquid colour: citrus e-liquids are usually clear to pale yellow or amber. Slight darkening over time is normal and is not a sign that the liquid has gone off, though very dark liquid after a year or more of storage is worth replacing.

The 60ml bottle is bigger than the 50ml of liquid inside it on purpose. The empty headspace is not wasted: it is what lets you add a 10ml nicotine shot without overflowing, and it gives you room to shake the contents properly. If you vape at 0mg you can leave the extra space as it is, and it also helps when you shake the bottle because the liquid moves more freely.

For travel and day-to-day use, the most practical habit is to keep the main bottle at home and decant into a small 10ml bottle for the bag. Decanting reduces the chance of pressure leaks on a plane or in a warm pocket, and it means you are not carrying a bottle that is more than half full of liquid you will not use that day. Always wipe the nozzle after filling, as liquid left on it will gather dust and dried residue.

Capacity, VG/PG ratio and the shortfill maths

Shortfills exist because of how UK vaping rules are written. Nicotine-containing e-liquids in the UK can only be sold in bottles of 10ml or less, and the nicotine strength is capped at 20mg/ml. A bottle larger than 10ml therefore cannot legally contain nicotine, so shortfill makers sell a larger bottle of nicotine-free liquid, leave headroom in the bottle, and let you add a separate 10ml nicotine shot yourself. That is why this product is 50ml of liquid in a 60ml bottle.

The same rules explain why disposables and refill pods carry strict limits. Nicotine strength in UK vaping products is capped at 20mg/ml, and refillable tank capacity is capped at 2ml. These caps apply across the market, and sale of single-use disposable vapes has been prohibited in Great Britain since 1 June 2025, which is a large part of why many former disposable users have moved to refillable kits.

The specifications you need to know:

• Liquid volume: 50ml
• Bottle capacity: 60ml
• Nicotine as supplied: 0mg/ml
• VG/PG: normally around 70VG/30PG in this style. Check the label on your bottle, as the exact ratio can differ by batch
• Nicotine type once added: freebase nicotine, as supplied in standard UK nicotine shots

The strength you reach depends on how much nicotine you add. Using a standard 10ml shot at 18mg/ml, the maths works out like this:

• No shot: 0mg/ml
• Half a shot (5ml of 18mg/ml) into the 50ml: about 1.6mg/ml in 55ml
• One full shot (10ml of 18mg/ml): 3mg/ml in 60ml
• One full shot at 20mg/ml: about 3.3mg/ml in 60ml
• Two shots of 18mg/ml: about 5.1mg/ml, but this needs 70ml of capacity, so you would pour into a larger empty bottle

Every shot also adds a small amount of PG or VG of its own, so the flavour is diluted by about one sixth when you add a full shot. In practice the difference is slight, and most people do not notice it with a flavour as lively as grapefruit. If you want flavour to stay at its strongest, vape it at 0mg or add only half a shot.

Nicotine strength guidance

This liquid is supplied nicotine-free, so the choice is yours. The right strength depends on how much you smoked or vaped before, what kind of device you use and how hard you draw. Below is a practical guide for freebase nicotine in a high-VG liquid. It is general information and not medical advice, and if you are unsure, the NHS stop smoking services can help you work out a plan.

• 0mg/ml: for people who vape for the flavour and habit and no longer need nicotine, or who are tapering down. Smooth and mild.
• 3mg/ml (one 10ml 18mg shot): the usual starting point for ex-smokers on sub-ohm kits who smoked a light to moderate amount. Gentle throat hit and enough nicotine to keep cravings in check for many people.
• 6mg/ml (two shots, in a larger bottle): for heavier former smokers using a sub-ohm device who find 3mg leaves them reaching for the device too often. At this strength the throat hit is noticeably firmer.

It is worth knowing why shortfill nicotine tops out at low numbers. Freebase nicotine is harsh. At the high wattages and large vapour volumes of sub-ohm vaping, strengths much above 6mg/ml feel rough on the throat and deliver more nicotine per puff than most people want. People who need higher strengths generally use nicotine salt liquids in low-power pod devices instead, which are smoother at 10mg/ml to 20mg/ml. Those are sold in 10ml bottles and are a separate product category from this shortfill.

Signs that your strength is too high include a headache, dizziness, nausea, a racing heart, a sore throat or feeling jittery. If you notice any of these, stop vaping, drink some water, get some fresh air and drop to a lower strength next time. Signs that it is too low include constant cravings, chain vaping, irritability and finding yourself drawing harder to chase satisfaction. In that case, raise the strength by a small step rather than jumping straight to the top.

A few additional points to keep in mind:

• Your needs change with the device. A strength that feels right on a 15W pod kit can feel harsh on a 60W sub-ohm tank, because the second delivers far more vapour per puff.
• Citrus acidity can make the throat feel slightly sharper than a dessert flavour at the same strength, so you may prefer to start a notch lower.
• Non-smokers should not start vaping nicotine. If you have never smoked, 0mg is the only sensible option, or better still, not vaping at all.

Coils, mesh technology, battery and device pairing

A 70VG shortfill needs hardware that can move thick liquid onto the coil quickly. That points to sub-ohm tanks, or open-pod kits with a mesh coil rated for high-VG liquid. Tight, high-resistance coils built for thin liquid and low power can struggle with it, which shows up as dry hits and a burnt taste.

Matching the coil to the liquid:

• Mesh coils, 0.15 to 0.4 ohm: the usual match for sub-ohm tanks at roughly 40W to 80W. Mesh spreads the heating over a wide surface, which gives even vaporisation and good flavour, and it handles high-VG liquid well.
• Mesh coils, 0.6 to 0.8 ohm: found in many open-pod kits, usually run at 15W to 30W. A good fit for a looser mouth-to-lung style, provided the coil is rated for high-VG liquid.
• Traditional round-wire coils with cotton: work in sub-ohm tanks too, but need priming with care so the cotton is fully wet before first use.
• Coils of 1.0 ohm and above, built for mouth-to-lung and thin liquid: generally not suited to this bottle. Thick liquid may not wick fast enough.

Always check the wattage range printed on the coil head and stay inside it. Start in the lower third of the range, and raise it only if the flavour feels thin. Citrus and sweetened liquids are tougher on coils than plain liquids, so expect a coil life of roughly one to two weeks of regular use. If the flavour goes flat, if you taste burnt cotton, or if the tank begins to gurgle, replace the coil.

On battery and charging, the rule is that more power drains a battery faster:

• Built-in battery pod kits: typically 500mAh to 1,500mAh. At 15W to 25W, a day of use is realistic from the larger cells, so plan on charging nightly. Use the USB-C cable that came with the device and a standard wall plug, not a high-output fast charger designed for a laptop.
• Removable-cell mods: use 18650 or 21700 cells with a continuous discharge rating suited to your wattage, and use a proper external charger. Never carry loose cells in a pocket or bag, use a case.
• Charging safety: do not charge unattended or overnight on soft furnishings, do not use a damaged cable or a cell with a torn wrap, and stop using any battery that swells, overheats or smells odd.

If you are coming from disposables, note that a refillable kit running this liquid will drain a battery faster than a disposable's fixed low-power setup, simply because it makes more vapour per puff.

Who Groovy Grapefruit is for, and who should skip it

No flavour suits everyone, and a clear answer saves you money. Here is who this bottle makes sense for.

It is a good fit if you:

• Are an adult smoker or ex-smoker using vaping to stay off cigarettes and want a fruit flavour that is not sticky or heavy.
• Already own a sub-ohm tank, mesh pod kit or adjustable mod and want a larger bottle at a lower cost per millilitre.
• Have been using disposables and want a refillable setup that is cheaper to run and creates less waste. Disposable vapes have been banned from sale in Great Britain since 1 June 2025, and many people are moving to refillable kits.
• Enjoy citrus, tart fruit or drier flavours rather than sweet confectionery.
• Want to control your own nicotine level, including stepping down towards 0mg over time.

It is probably not the right choice if you:

• Have never smoked or vaped. Nicotine is addictive and vaping is not risk-free. Non-smokers and anyone under 18 should not buy or use it.
• Want a high-strength liquid for a tight mouth-to-lung pod device. You are better served by a nicotine salt liquid in a 10ml bottle.
• Prefer sweet, creamy or dessert flavours. Grapefruit is tart and slightly dry by nature.
• Do not want to refill, mix or clean a device. A shortfill asks more of you than a pre-filled pod.
• Are pregnant, breastfeeding or living with a heart condition. Speak to your GP or pharmacist before using any nicotine product.

There is also a middle group worth mentioning: people who want a lower-effort start. If you have no refillable hardware at all, buy the device first. A starter kit with a mesh coil and a tank of 2ml capacity is the simplest entry point, and it is the kind of kit for which a high-VG 50ml bottle is well suited. If you are still deciding between formats, get a small test bottle in the same flavour before committing to 50ml.

How to use it: adding nicotine, shaking, steeping and filling

Using a shortfill takes a few minutes the first time and becomes routine after that. Follow the steps in order.

• Step 1, check the bottle. Make sure the tamper-evident seal is intact and the cap is tight. Wipe the outside of the bottle if needed.
• Step 2, decide your strength. If you vape at 0mg, skip to step 6. For 3mg/ml, you need one 10ml nicotine shot at 18mg/ml. Check that the shot is a standard 10ml bottle and that it is in date.
• Step 3, open both bottles over a sink or tray. Nicotine liquid on the skin can be absorbed, so work somewhere you can rinse off any spill quickly.
• Step 4, pour in the shot. Squeeze the entire contents of the nicotine shot into the 60ml bottle. The extra 10ml of space is there for exactly this.
• Step 5, close and shake. Tighten the cap and shake firmly for at least 30 seconds, turning the bottle over a few times so the nicotine disperses evenly. Write the date and the strength on the bottle with a marker.
• Step 6, let it rest. Fruit liquids do not need long steeping, but a rest of a few hours to a day helps the nicotine and flavour blend smoothly. Leave the cap on, store it upright, out of direct sunlight.
• Step 7, fill the tank. Open the tank's fill port, angle the nozzle against the side wall, squeeze gently and stop at the max fill line. Do not pour liquid down the central chimney, as that will flood the coil.
• Step 8, prime the coil. Leave a new coil to soak for five to ten minutes after filling. Take two or three gentle puffs without firing at full power, then start in the lower part of the wattage range.

A few habits make the experience better. Keep the device upright when you are not using it, so liquid does not seep into the airflow. Take slow, steady draws instead of fast, hard ones, which can pull liquid through before it vaporises. Do not chain vape for long stretches, as the coil needs a few seconds between puffs to re-wet. When you want to change flavours, empty the tank, rinse it with warm water, dry it thoroughly and fit a fresh coil, otherwise the old flavour will linger.

Finally, if you vape at 0mg and are happy with it, there is no reason to add anything at all. The bottle is ready to use from the moment you open it.

Troubleshooting common problems

Most problems with a shortfill come from the hardware or the settings, not the liquid. Here are the issues we see most often and what to try.

• Burnt or acrid taste: usually a dry coil or a worn one. Make sure the coil was primed, check there is liquid above the coil's fill holes, and lower the power. If the taste stays, fit a new coil. Chain vaping and running power above the coil's rating cause this most often.
• Weak or flat flavour: the coil is probably tired. Citrus liquids age coils faster than plain ones. Try a new coil, then try a slightly higher or lower wattage.
• Gurgling or spitting: too much liquid is reaching the coil or condensation is collecting. Wipe the mouthpiece, try a slightly more open airflow, and never overfill past the line.
• Leaking from the tank: check that the tank is assembled with all seals seated, the coil is screwed in fully and the tank was not overfilled. Changes in air pressure can also push liquid out, so keep the device upright when travelling.
• Dry hits: the coil is not wicking quickly enough. Confirm the coil is rated for high-VG liquid, prime it for longer, and lower the power.
• Harsh throat hit: the nicotine is too strong for your setup or the wattage is too high. Drop to a lower strength or turn the power down in small steps.
• Too sour or too sweet: adjust the wattage. Cooler is sharper and more acidic, hotter is rounder and sweeter.
• Sticky residue on the nozzle: wipe it with a damp tissue after each fill. If the nozzle has clogged, soak the tip in warm water and dry it before use.
• Device will not fire: check the battery charge, clean the contacts and make sure the coil is screwed in. If it still fails, try a different coil before suspecting the battery.
• Lost sense of flavour: this is usually vaper's tongue. Switch flavours for a day or two, drink water, and the sense of taste normally returns.

If you notice an odd smell, a cloudy or separated liquid, or a bottle that has been leaking inside its packaging, do not use it, and contact the shop with your order details. If a problem looks like a fault rather than a settings issue, you also have statutory rights under the Consumer Rights Act 2015 for goods that are faulty or not as described.

Value for money and honest comparisons

The main argument for a 50ml shortfill is cost per millilitre. Because a single bottle holds as much liquid as 25 standard 2ml disposable tanks, you are paying for liquid rather than for a battery, a plastic shell and packaging that are all thrown away together. Over a month of regular use, the saving over disposables can be large, though you do need to factor in the one-off cost of a device and the ongoing cost of replacement coils, which typically run a few pounds each and need changing every week or two.

Here is how the format compares with other routes:

• Versus disposables: a shortfill costs less per millilitre and creates less waste, but it needs a refillable kit and more effort. A disposable needs nothing but a charge, and the 20mg/ml nicotine cap and 2ml tank limit set the ceiling on what it can deliver. They have also been banned from sale in Great Britain since 1 June 2025.
• Versus 10ml nicotine salt bottles: nic salts are smoother at high strengths and work in low-power pod kits. They cost more per millilitre and need a lot of small bottles. A shortfill gives you more vapour, more liquid and a lower nicotine ceiling.
• Versus other 50ml shortfill brands: there is a lot of choice. Brands with long-established followings, such as Dinner Lady or Vampire Vape, offer a wider catalogue of dessert, candy and drink-style flavours. The Badass Blend line is simpler, centred on straightforward fruit profiles. Some competing shortfills are cheaper per millilitre and some are more complex in flavour. This one is not the cheapest 50ml on the market and does not claim to be.

Where Groovy Grapefruit makes sense is for someone who specifically wants a clean, tart citrus flavour and does not want to pay for a premium-priced, boutique line. If you only vape a couple of millilitres a day, a 50ml bottle will last several weeks, which stretches the value further.

A practical way to compare prices fairly is to work out the cost per 10ml. Divide the bottle price by five for a 50ml, then compare with the price of a 10ml nicotine salt bottle or a disposable. Do the same calculation with any other shortfill you are considering. Keep in mind that a nicotine shot, if you use one, is an extra cost, so include it when you compare against a bottle that comes pre-mixed.

Storage, safety and recycling in the UK

Look after the bottle and it will keep its flavour for a long time. Store it upright, in a cool, dark place such as a cupboard, away from radiators, windows and cars on warm days. Heat and light break down flavourings and darken the liquid. Keep the cap tight whenever you are not filling. Most e-liquids keep their quality for a year or two if stored properly, and an unopened bottle will outlast one that has been opened and left half empty.

Safety points that matter, especially if you add a nicotine shot:

• Keep out of reach of children and pets. Nicotine liquid is poisonous if swallowed or absorbed through the skin in quantity. Mixed bottles must be stored somewhere secure and out of sight.
• Label your mixed bottle with the strength and date, and never decant liquid into a container that looks like a drink.
• If liquid gets on your skin, wash it off with soap and water straight away. If it gets in your eyes, rinse with clean water for several minutes and seek advice.
• If someone swallows liquid, call 999 or NHS 111 straight away and have the bottle to hand.
• Age: the product is for adults only. Retailers in the UK must not sell to anyone under 18.

Recycling is the other half of responsible use. Empty bottles are plastic, and many UK councils accept clean plastic bottles in household recycling, although some do not take small items, so check your local authority's guidance. Shake out any remaining liquid into a tissue and dispose of it in general waste, then rinse the bottle. Cardboard outer packaging goes in the paper and card recycling.

Hardware is different. Vape devices and batteries contain lithium cells and must never go in the household bin or kerbside recycling, as damaged cells can cause fires in collection vehicles and recycling plants. Take them to a household waste recycling centre, a supermarket or retailer battery and small electrical drop-off point, or any shop that offers a take-back scheme. Used coils are small and contain metal and cotton, and your local recycling centre can advise on where to put them if you are unsure.
