Kingston AU Gold 100ml E-Liquid is part of Kingston's large-format e-liquid range, aimed at vapers who go through juice quickly and would rather not keep restocking small bottles every few days. The headline feature is the bottle itself: 100ml of liquid in one go, fewer reorders, and generally a lower cost per ml than buying the same total volume across a stack of 10ml bottles.
What Is Kingston AU Gold 100ml E-Liquid?
Kingston is a well-established name in UK vaping, known for straightforward, no-frills e-liquid at accessible prices rather than elaborate packaging or gimmicks. The AU Gold profile sits within that same range, sold in the large 100ml format used across most of Kingston's bottled liquids, rather than the smaller 10ml bottles that pre-mixed nic salts usually come in.
That size matters more than it might seem. Under the UK's Tobacco and Related Products Regulations (TPD), any e-liquid containing nicotine has to be sold in bottles of 10ml or less. A 100ml bottle like this one is therefore supplied nicotine-free (0mg) as standard. It's a large bottle of flavoured base liquid, not a ready-mixed nic salt straight off the shelf.
If you want nicotine in it, you add it yourself with a 10ml nic salt shot, which tops the bottle up to whatever strength you choose, within the UK legal limit. This isn't a workaround or a grey-area trick, it's the standard, fully legal way 100ml e-liquids are sold across the UK market, regardless of brand.
Bottle Size and What You Get
You're buying one 100ml bottle containing the AU Gold flavour blend at 0mg. Nothing else is included, so factor a separate nic salt shot into your order if you plan to vape it with nicotine. The bottle itself uses a standard childproof cap and nozzle designed for dripping or refilling tanks and pods directly, without needing to decant it elsewhere first.
Who This E-Liquid Suits
- Vapers who get through juice quickly and don't want the hassle of reordering every week.
- Anyone who already buys nic salt shots separately and wants a larger base bottle to mix them into.
- Vapers who prefer to set their own exact nicotine strength rather than relying on a fixed, pre-mixed option.
- People who'd rather manage one large bottle than several small ones rattling around in a bag or drawer.
It suits people who don't mind a short mixing step in exchange for volume and control. If you'd rather open a bottle and vape immediately with zero setup, a pre-mixed 10ml nic salt is the more straightforward route, this isn't that, and it's worth knowing the difference before you buy.
How to Use It and Get the Best From It
Mixing is simple and doesn't need any special kit. Empty a 10ml nic salt shot into the 100ml bottle, check the fill line first, as most 100ml bottles are designed with enough headroom for exactly one shot. Screw the cap back on tightly and shake the bottle firmly for around 30 seconds to a minute. This spreads the nicotine through the liquid evenly rather than leaving it concentrated near the top.
Give it another shake before your first vape, and let the bottle sit for a few minutes so any air bubbles from mixing can settle out. Some vapers also let a freshly mixed bottle rest for a day or two before using it, on the theory that it lets the flavour settle in properly. It isn't essential, but it's a common habit and worth trying if you're not in a rush to use it straight away.
When filling a tank or pod for the first time with this liquid, prime the coil properly first. A few drops applied directly to the coil or wick before it goes into the device, followed by a short wait before vaping, helps stop dry hits and extends how long the coil lasts. This step matters more with thicker, high-VG liquids, which take longer to soak fully into a wick than thinner mixes.
Once everything is primed and mixed, treat it like any other e-liquid: fill your tank or pod to the recommended level, avoid overfilling past the marked line, and give the bottle a shake before every subsequent refill, since nicotine and flavouring can settle slightly between uses.
Nicotine Strength Guidance
UK nicotine salt e-liquids are legally capped at 20mg/ml (2%), and that's the strongest any nic shot sold here can be. When deciding how much to add to this bottle, it helps to think in rough bands:
- 0mg, the bottle as supplied, before you add anything. Flavour only, no nicotine at all.
- Low strength (around 3-6mg), suits vapers who already smoke very little, or who are gradually stepping down from a higher strength.
- Medium strength (around 10-12mg), a common middle ground for regular vapers, particularly those moving across from freebase e-liquids.
- High strength (up to the 20mg/ml UK cap), generally better suited to heavier ex-smokers who need a stronger hit to stay off cigarettes.
If you're not sure where to start, it's much easier to mix a bottle lower and go stronger next time than to try to water down one that's too harsh. Nicotine products are strictly for adults aged 18 and over, and if you're new to nic salts, starting lower and adjusting from there is the sensible approach.
How It Compares to Other Nic Salt Options
Set against a standard pre-mixed 10ml nic salt, this 100ml format trades a bit of convenience for value and control. A 10ml bottle is ready the moment you open it, no mixing, no shaking, no waiting around. This bottle asks for a few minutes of setup, but in return you get ten times the liquid in one purchase, the ability to fix your own exact strength, and usually a lower cost per ml once the price of a nic shot is factored in.
Compared with other 100ml e-liquids on the market, Kingston's approach has generally been about keeping things simple and affordable rather than chasing unusual or complicated flavour combinations. If you've used other bottles from the Kingston range before, the format and mixing process here will feel identical, it's the AU Gold profile itself that distinguishes this particular bottle, not the mechanics of getting it ready to vape.
It's also worth being clear about what this product isn't. It isn't a disposable vape, an all-in-one pod, or anything meant to be used straight from the bottle without a device. It's a mixing base built for refillable tanks, pod systems, and sub-ohm kits that take standard bottled e-liquid.
Care and Storage
Store the bottle upright, away from direct sunlight and heat, and well out of reach of children and pets, the childproof cap is there for a reason, so make sure it clicks fully shut after every use. A cool, dry cupboard is ideal. Avoid leaving it in a hot car, on a windowsill, or anywhere near a radiator, since heat and light can degrade both flavour and nicotine over time.
Once you've mixed in a nic shot, try to use the bottle within a reasonable timeframe rather than letting it sit unused for months. Nicotine strength and flavour can both drift gradually over long periods, especially if storage conditions aren't ideal. Shake the bottle before every use, even once it's been mixed and left to settle, as the nicotine and flavouring can separate again slightly between refills.
If the liquid darkens noticeably, smells different from when it was first mixed, or the flavour seems off compared to earlier in the bottle, don't vape it, discard it and start with a fresh one instead.
FAQ
Does this bottle already contain nicotine?
No. As a 100ml e-liquid, UK regulations mean it has to be supplied at 0mg. You add nicotine yourself using a separate 10ml nic salt shot if you want a nicotine-containing vape.
What nicotine strength should I mix it to?
Anywhere from 0mg up to the UK legal cap of 20mg/ml, depending on your preference and experience. See the strength guidance above if you're not sure where to start.
Do I need any special equipment to mix it myself?
No. You just need a 10ml nic salt shot at your chosen strength, poured directly into the bottle, followed by a firm shake.
Can I use it in any vape device?
It works well in standard refillable tanks, pod systems, and sub-ohm kits. It isn't designed for disposables or closed-pod systems that don't accept refills.
Is this suitable for beginners?
It's suitable for anyone 18 or over, but the mixing step means slightly more setup than a ready-to-vape 10ml nic salt. If you'd rather skip mixing altogether, a pre-mixed nic salt bottle may suit you better.
How long does a 100ml bottle typically last?
That depends heavily on how often you vape and what device you're using, but the larger volume generally means far fewer bottle changes than working through several 10ml bottles over the same period.
Can I mix in more than one nic shot for a stronger blend?
You can, but always stay within the UK legal maximum of 20mg/ml once everything is combined. Check the total volume and nicotine content of the shots you're adding so the final mix doesn't exceed that cap.
