Bar Juice 5000 Nic Salts Sour Rainbow: what you are buying

Bar Juice 5000 Nic Salts Sour Rainbow is the Sour Rainbow option in the Bar Juice 5000 Nic Salts range, priced at £2.89. We list what the product actually is rather than padding it with specifications we cannot verify.

The full Bar Juice range is at Bar Juice, and this line alone runs to 45 flavours. Everything we ship is genuine UK-compliant stock.

Getting the best from the bottle

Nicotine salt bottles are capped at 10ml in the UK, which is why you buy them in small bottles rather than large ones.

  • Prime a fresh coil or pod before the first draw: fill it, then wait a few minutes so the wick soaks properly.
  • Store bottles upright, out of sunlight and away from heat, which keeps the flavour truer for longer.
  • A burnt taste usually means the wick has dried out rather than the liquid being at fault.
  • Keep bottles away from children and pets, and use the child-resistant cap as intended.

None of that is complicated, but it is the difference between a pod that tastes right to the end and one that does not.

Is Sour Rainbow the right pick for you?

The quickest way to choose is to ask which flavour family you reach for most. Sour Rainbow is best judged against the other options in this line rather than in isolation.

  • If you want an all-day vape, a more balanced profile usually lasts longer before palate fatigue sets in.
  • If you rotate flavours, pair this with something from a different family so your palate resets between them.
  • On cooling, this reads as an uncooled profile, which suits anyone who finds menthol overpowering.
  • If you are switching from cigarettes, strong sweet flavours can feel unfamiliar at first, and many adults settle after a week or two.

Nobody gets every flavour right first time, which is why the multibuys exist.

Other flavours in the Bar Juice 5000 Nic Salts range

Sticking with the line you already like is easier than starting from scratch elsewhere. 45 flavours sit under this name, including:

Rotating between two profiles keeps both tasting sharper for longer.

Ordering, delivery and the legal bit

This is an 18+ product and age verification applies to every order. Nicotine is addictive, and these products are for adults who already smoke or vape.

Browse all e-liquids, or head to the sale if price is the deciding factor. If you are unsure whether this fits your device, check the listing details before ordering.

Choosing your nicotine strength

This e-liquid is listed in 10mg and 20mg. No UK retailer can sell above 20mg per ml, so strength choice is really about going lower.

  • 20mg gives the firmest throat hit and suits heavier former smokers, or anyone who finds lower strengths leave them vaping more often.
  • 10mg is the common middle ground: enough to satisfy without the harshness some find at 20mg.

If you are unsure, most adults switching from a pack a day start at the higher end and drop down later. 10mg options and 20mg options are browsable separately if you want to compare.

What the multibuy actually saves you

The offer on this line is buy 5 for £10. At £2.89 each, 5 would normally be £14.45, so the bundle saves £4.45 and works out at £2.00 apiece.

That sits under the £20.00 free delivery threshold, so either add something small or take the offer twice. The offer applies across the qualifying range, not just this one flavour.

Baskets above £20 ship free within the UK. Order before 4pm on a working day and it leaves us that afternoon.

Where this sits in the Bar Juice range

A single product tells you little; the shape of the range tells you a lot. We stock 47 Bar Juice products, running from £2.89 to £9.99. That is a focused range rather than a sprawling one, which usually means fewer duds.

The full lineup is on the Bar Juice page. Other Bar Juice products worth a look:

Staying within a brand you already rate is the low risk way to try something new.

How it compares to the rest of the category

The useful question is not what it costs, but what else that money buys. We list 736 products in this category. At £2.89, this one sits at the affordable end.

  • Multibuy deals are where the price per unit drops hardest, and they can be mixed across flavours.
  • Reduced lines carry 1,558 products if the budget is the deciding factor.
  • Prefilled pods cost more per millilitre but remove the refilling entirely.

None of those is objectively right. They suit different routines and different budgets.

The running cost, worked out

Headline prices hide the number that actually matters, which is what a week costs you.

Without a published rating there is no honest per-puff maths to show, so we leave it out.

  • The buy 5 for £10 offer is the single biggest lever on that number.
  • Baskets over £20.00 ship free in the UK, so building to that threshold beats paying postage twice.
  • Nicotine strength changes consumption: many adults find a higher strength means reaching for the device less often.

Sour Rainbow against the rest of the line

Same product, different flavour, is the fairest comparison available. There are 45 options under this name:

Palate fatigue is real: rotating two profiles keeps both tasting sharper for longer. The buy 5 for £10 offer makes that cheap to do.

Why the UK market looks like this

It helps to know which limits are legal and which are commercial. UK rules cap nicotine at 20mg per ml, nicotine e-liquid bottles at 10ml, and prefilled pods and tanks at 2ml. That is why you buy small bottles often rather than one large one.

Since single-use devices were banned, the market moved to rechargeables. Rechargeable kits with replaceable pods took their place, which is why a device now comes with a charging port and a pod you swap rather than a sealed unit you bin. It also means the device outlives the flavour, which changes how you shop.

Everything we sell is UK-compliant stock bought through UK distribution. Sales are 18+ and every order is age-checked.

Looking after it, and what goes wrong

The faults people blame on a product are usually storage or priming.

  • Prime before the first draw. Fill, then wait a few minutes so the wick soaks fully. A dry first pull is what burns a coil.
  • Keep it cool and upright. Heat thins liquid and pushes it through seals, which is why a hot car is the usual cause of a leak.
  • Muted flavour is often you, not it. Palate fatigue is common on a single flavour, and rotating to a second profile resets it.
  • Store away from children and pets, and recycle spent hardware rather than binning it loose.

None of that is demanding, and it is the difference between a product that performs to the end and one that disappoints halfway.

Rotating a pair is the simplest fix for flavour fatigue.

Delivery, returns and buying with confidence

The buying side is straightforward. Weekday orders placed before 4pm are dispatched the same day, and UK delivery is free once your basket reaches £20.00. Tracked options are shown at checkout.

Consumables cannot be returned once opened, for obvious hygiene reasons. Faults and picking errors are resolved without argument. This is an 18+ purchase and orders are age-checked before they ship.

Nicotine is addictive. These products are for adult smokers and vapers.

Buying this as a first purchase

If this is your first order with us, a few things are worth knowing before you commit.

  1. Format. A bottle is the cheapest way to vape per millilitre, but you refill it yourself. Prefilled pods remove that job at a higher cost.
  2. Strength. This comes in 10mg and 20mg. Heavier former smokers usually start high and step down.
  3. Flavour. You are looking at Sour Rainbow. Pick a second from a different family so you have something to rotate to.

Get those three right and the rest is detail. The deals page is the cheapest way to try more than one at a time.

Common problems and how to avoid them

The same handful of issues account for nearly every complaint.

A burnt taste on a new bottle. Almost always a coil that was not primed. Fill it, then leave it a few minutes before the first draw so the wick saturates properly. Drawing on dry cotton scorches it, and once burnt it does not recover.

Leaking. Usually heat or pressure. Warmth thins liquid and pushes it through seals, so a hot car or a sunny windowsill is the usual culprit. Cabin pressure on a flight does the same thing, which is why storing spares upright in a bag beats loose in a pocket.

Flavour fading. Frequently the palate rather than the product. If a flavour dulls after a week, switching to a contrasting profile for a day or two usually brings it back sharply.

Buying the wrong fitment. Pods are not universal, and even within one brand the families differ. Check the listing names your device before ordering rather than after. Spares and accessories are grouped separately if you need a replacement part.

Building a rotation instead of buying one thing

The single most common mistake is buying five of the same flavour. Palate fatigue sets in faster than people expect. A profile you loved on day one can taste flat by day ten, not because the product changed but because your palate stopped noticing it.

The solution is simply how you buy. Keep two profiles from genuinely different families on the go, and alternate between them. Something sweet paired with something sharp, or a fruit paired with a menthol, resets the palate each time you switch. Two flavours in rotation will each last noticeably longer than either would alone.

Sensible pairings from the same line:

The buy 5 for £10 offer exists precisely for this, and it can be mixed across flavours rather than spent on one.

Pros & cons

Pros

  • Best value per ml in the category
  • Choose your own device and coil
  • Available in a wide strength ladder

Cons

  • Refilling can leak if you overfill
  • Coil priming has a small learning curve
  • You handle the bottle — less discreet than pods

Customer Buying Tips

  • Match the strength to how much you smoked: 20+/day → 10-20 mg nic salt; 10/day → 10 mg; under 5/day → 3-6 mg freebase.
  • Match the ratio to your device: pod kits take 50/50, sub-ohm tanks take 70/30 shortfill.
  • Don't overfill: leaving the airhole clear prevents gurgling and leaking.
  • Shake before use so the nicotine and flavour integrate evenly.

Frequently asked questions

Can I mix flavours in one order?

Yes. Multibuy offers apply across the qualifying range, so you can spread a bundle over several flavours instead of committing to one.

How many puffs does the Bar Juice 5000 Nic Salts Sour Rainbow give?

No puff rating is published for this listing, so we do not quote one. How long it lasts depends on your device and how often you vape.

Do I have to be 18 to buy this?

Yes. Sales are strictly 18+ and every order is age-verified. Orders that cannot be verified are refunded rather than sent.

Is it genuine stock?

Yes. Everything we list is sourced through UK distribution and is UK-compliant, including the 2ml pod, 10ml bottle and 20mg nicotine limits where they apply.

What if I do not like the flavour?

Flavour is personal and we cannot resell an opened consumable, so the multibuys are the low risk way to try more than one. Buying a pair from different families is the usual approach.

Is there a multibuy on this?

Yes, the offer is buy 5 for £10, and it can be mixed across qualifying flavours rather than being limited to this one.
