Seriously Slushy Shortfill E-Liquid By Doozy

Seriously Slushy Shortfill E-Liquid by Doozy is built around one idea: the icy, syrupy hit of a fairground slush cup, poured into a vape bottle. Doozy is a well-established UK e-liquid brand, and this shortfill line leans hard into that slush-machine character rather than trying to be a subtle, sippable all-day flavour. If you want your vape to taste like the cup you'd queue for at a fair, this is the shortfill to look at first when you buy Seriously Slushy Shortfill E-Liquid by Doozy.

"Shortfill" refers to how the bottle is filled, not the flavour itself: the bottle is deliberately left short of full so there's headroom to add a nicotine shot before you vape it, rather than being topped up completely like a standard 10ml e-liquid. That's why you'll see it labelled 0mg on the bottle even though most people using it will add nicotine themselves, more on that below.

The flavour range

The Seriously Slushy Shortfill E-Liquid by Doozy UK range runs to around six flavours, each built to mimic a specific slush-cup profile rather than a single fruit note. A few stand out from the rest:

• Berry Watermelon, a mixed berry base layered over sweet, slightly savoury watermelon. It reads closer to a berry slush than a straight watermelon vape, with the watermelon there to round off the finish rather than lead it.
• Grape Soda, fizzy, purple, and unapologetically artificial in the best way, this is the one that tastes most like an actual slushy machine flavour. Good if you want something with real presence on the exhale.
• Lemon Lime, sharper and more citrus-forward than the berry options, this one sits closer to a fizzy drink than a fruit bowl. Works well as a palate-cleanser flavour if you're rotating between two or three bottles.
• Lime Berry, lime pulled back slightly and paired with a darker berry note, giving a tarter finish than Berry Watermelon without going full citrus like Lemon Lime.

The remaining flavours in the line round out the icy, mixed-fruit theme, giving you options either side of tart and sweet. Because every flavour shares that slush-drink DNA, picking between them tends to come down to whether you prefer berry-forward, citrus-forward, or soda-style sweetness, rather than picking between wildly different categories.

Setting it up without a burnt or muted taste

Shortfills like this one are designed to be paired with a nicotine shot before use, and getting the ratio and the setup right makes a real difference to how the flavour actually comes through.

• Shake before and after adding a nic shot. The flavourings and any nicotine shot need to be properly mixed, not just poured in and left. A short, firm shake settles everything and stops you getting a watery first few puffs followed by an overly strong batch further down the bottle.
• Let it steep briefly. Ten to fifteen minutes after mixing, before your first vape, lets the flavour settle rather than tasting sharp or "raw."
• Prime new coils properly. Drip a few drops directly onto the coil and let the tank sit for five to ten minutes before your first pull. Vaping on a dry coil is the single most common cause of a burnt taste with any shortfill, not just this one.
• Don't chain-vape a fresh coil. Take slower, shorter draws for the first tank so the wicking material has time to keep up. Rushing this stage is what turns a good flavour into a muted, slightly scorched one.
• Watch your wattage. Running noticeably hotter than your coil or kit's recommended range burns off the top notes fast, with a fruity, sweet profile like this one, that usually means losing the "slush" character first and being left with a flatter, sweeter aftertaste.
• Replace coils before they go stale. A tired coil mutes flavour long before it fails outright. If Seriously Slushy starts tasting thinner or flatter than it did on day one, a fresh coil is usually the fix, not a different bottle.

Who this suits

Seriously Slushy is aimed at vapers who want a genuinely sweet, dessert-drink style flavour rather than a straight fruit vape. If you've enjoyed slush puppies, fruit-flavoured fizzy drinks, or icy mixed-berry flavours in other brands, this range will feel familiar. It also suits anyone who likes rotating two or three bottles through the week, the four flavours above are distinct enough from each other to avoid taste fatigue, while staying within the same overall style.

It's less suited to vapers who prefer single-note fruit or menthol-heavy flavours, since the whole point of this range is a blended, slightly sugary complexity rather than one clean flavour doing all the work.

How it compares to similar shortfills

Against other UK shortfill ranges built around slush, soda, and mixed-fruit themes, Doozy's Seriously Slushy sits in familiar territory: bottled to leave room for a nic shot, priced as an everyday option rather than a premium import, and built around bold, drink-inspired flavours rather than restrained single fruits. Where it tends to differ is in how consistently "icy drink" the flavours read rather than "fruit with a hint of something else", Grape Soda in particular leans further into the soda side than a lot of competing grape vapes, which either play it as straight fruit or add a heavier menthol edge. If you've found other slush or soda-style shortfills either too artificial or too weak on flavour, this range is worth trying as a middle point between the two.

Compared to nic salt bottles, the trade-off is convenience versus control. A 10ml nic salt comes pre-mixed at a fixed strength and is ready straight out of the box, which suits vapers who want zero setup. A shortfill like this one takes an extra couple of minutes to prepare with a nic shot, but you get far more juice per bottle and the flexibility to dial the final strength to whatever suits you, within the legal limit. If you'd rather not deal with mixing at all, a nic salt version of a similar fruit-soda flavour is the more direct alternative; if you're happy with a short setup step in exchange for a bigger bottle and more control, this shortfill format makes sense.

Nicotine strength guidance

Seriously Slushy Shortfill E-Liquid by Doozy is sold with no nicotine in the bottle itself, it's a 0mg shortfill designed to have a nicotine shot added by the vaper before use, rather than being vaped straight from the bottle if you want nicotine. If you're happy vaping nicotine-free, it can be used exactly as sold.

If you do want nicotine, add a nic shot before your first vape and shake well, as above. Under UK TPD regulations, the maximum strength for any nicotine-containing e-liquid sold in the UK is capped at 20mg/ml (2%), so make sure whatever combination of shot and shortfill you're using stays within that limit. If you're newer to vaping or coming from a lighter smoking habit, it's worth starting with a lower-strength nic shot and adjusting up rather than going straight for the maximum. This product, like all nicotine-related vape products, is intended strictly for adults aged 18 and over.

Care and storage

Keep the bottle upright, out of direct sunlight, and somewhere reasonably cool, heat and UV light are what degrade flavour and any added nicotine fastest over time. A cupboard or drawer works better than a windowsill or a car glovebox in summer. Once opened and mixed with a nic shot, try to use the bottle within a few months for the best flavour, and always keep it well out of reach of children and pets, it should be treated the same as any other product containing nicotine once a shot has been added, and stored securely even before that as a matter of habit.

FAQ

Does Seriously Slushy Shortfill E-Liquid by Doozy contain nicotine?

No, not as sold. It's a 0mg shortfill with space in the bottle to add your own nicotine shot if you want one.

What's the strongest I can make it?

Once you add a nic shot, the total strength must stay within the UK's legal cap of 20mg/ml (2%) for any nicotine e-liquid.

Why does it taste burnt after I fill my tank?

Almost always a priming issue rather than the e-liquid itself. Prime the coil with a few drops before use, let it sit, and take slow first draws rather than chain-vaping straight away.

Which flavour should I start with?

Grape Soda if you want the boldest, most recognisably "slushy" flavour; Lemon Lime if you'd rather something sharper and less sweet; Berry Watermelon or Lime Berry if you want something in between.

Can I mix flavours from this range?

Yes, since they share a similar slush-style base, flavours like Berry Watermelon and Lime Berry combine well if you want to build your own blend rather than sticking to one bottle.

Is this suitable for beginners?

Yes, provided you're an adult vaper. The shortfill format is straightforward once you're comfortable adding a nic shot, and the sweet, drink-inspired flavour is generally easy to get on with.
