Yeti Sourz 100ml: the sour end of the Yeti shelf

Yeti Sourz 100ml is Yeti's sour focused shortfill, sold at £6.99 for the 100ml bottle and supplied nicotine free at 0mg. It is one of five Yeti lines currently listed with us, and it is the one that trades temperature for tang.

The specific flavour options carried under this listing appear on this page, so pick from the selector rather than guessing. What the name commits to is a style rather than a single fruit. Sourz points at the sweet shop, at the sharp coating on a chewy sweet, at the pucker that arrives a fraction of a second before the sugar does.

That is a genuinely different proposition from most of what fills the shortfill shelf. The bulk of 100ml bottles sold in the UK sit somewhere between ripe fruit and dessert, with cooling bolted on. Sour is a smaller category because it is harder to get right, and it divides opinion more sharply than almost anything else in vaping.

You can see the full Yeti line on the Yeti brand page, and everything we carry in the same 100ml nicotine free format is grouped in the shortfill collection.

How sour behaves differently from every other flavour note

Sweet, cold, creamy and fruity all register on the palate in fairly predictable ways. Sour does not, and that is worth understanding before you commit to a full 100ml of it.

Sourness in vaping comes from acidic compounds, most commonly the food acids also used in confectionery. Unlike sweetness, which spreads evenly, sour concentrates along the sides of the tongue and triggers a physical response. Your mouth waters. That salivation is not incidental, it is a large part of why sour liquids feel refreshing rather than cloying, and it is why some adults find they can vape a sour blend for far longer in one sitting than a heavy dessert.

The flip side is that acidity is fatiguing in a way sweetness is not. A sour note that reads as bright and moreish for the first hour can start to feel abrasive by the fourth, particularly at higher power. Adults who love sour liquids almost universally run them alongside something rounder rather than as their only bottle.

There is also an interaction worth knowing about. Sour and cold amplify each other. If a sour blend also carries a cooling element, the combined effect is considerably sharper than either would be alone. That is not a fault, it is the intended experience for a lot of sweet shop profiles, but it does mean the same nominal intensity feels stronger than you might expect.

If this is a style you already know you enjoy, the wider e-liquid range lets you filter far beyond a single brand.

When to reach for it, and when not to

The most useful thing anyone can tell you about a sour liquid is not what it tastes like, it is when it works.

It suits

• Palate resets. After a coffee, after a heavy meal, after a day spent on a sweet bakery flavour. Sour cuts through residue better than almost anything.
• Warm weather and long sessions. The salivation effect keeps your mouth from drying out the way a thick, sugary blend can.
• Adults bored of fruit. If every bottle you have tried recently has blurred into the same generic berry, sour is the fastest way to feel something distinct again.

It suits less well

• First thing in the morning. Acidity on an empty stomach is not to everyone's taste.
• As a sole all day bottle. Possible, and some people manage it happily, but most find it wears on them.
• Anyone with a sensitive throat. Sour plus high power plus a tight draw is an unforgiving combination.

The honest recommendation is to treat this as one half of a rotation rather than a single purchase. That is also the most economical way to buy at this price, since two bottles get you closer to free postage than one does.

Sourz against the rest of the Yeti line

Yeti keeps five lines with us and they are deliberately spread across different territory, which makes internal comparison unusually straightforward.

Yeti Ice Cold 100ml shares the exact same £6.99 price and is the obvious counterpart. Ice Cold resets the palate through temperature, Sourz does it through acidity. Buying one of each gives you two genuinely distinct sensations for £13.98, and because they work through different mechanisms neither one dulls your response to the other the way two similar fruit bottles would.

Yeti No Ice 100ml at £10.99 strips out cooling entirely. If you find that sour combined with cold is too much at once, this is the direction to move in, though it does cost four pounds more per bottle.

Yeti Summit Series 100ml at £8.99 is the brand's step up line and the natural next purchase for anyone who has already settled on Yeti and wants to explore further within it.

Prices across the range run from £6.99 to £10.99, so Sourz sits at the accessible end. That matters if you are trying a style you are unsure about. Spending £6.99 to discover whether sour is for you is a far more sensible experiment than spending eleven pounds on the same question.

Nicotine free by law, and what that means for you

Every 100ml bottle sold legally in the UK is 0mg, and this one is no exception. The rule is that nicotine containing e-liquid must be supplied in containers of 10ml or less, at no more than 20mg per ml. There is no route around this for any brand, which is why large bottles are universally nicotine free.

The shortfill answer is to under fill the bottle so that adults who want nicotine can add it. Nicotine shots are compact bottles of high strength unflavoured base, bought separately, poured into the headroom and mixed in by capping and shaking hard. Ten to twenty seconds of vigorous shaking is the usual advice, and it matters. Under mixed liquid gives inconsistent strength from one refill to the next.

The resulting strengths are modest. A single 10ml shot at 18mg into 100ml of base leaves you at roughly 1.6mg per ml. If your bottle has room for two shots, you land near 3mg per ml across 120ml. Those numbers suit direct to lung vaping, where each puff carries a large volume of vapour and low strength liquid is the norm.

If you want a higher nicotine level, this format is the wrong tool for the job. Higher strengths live in small bottles, and our nicotine salt e-liquid range covers that side of the shelf, including the 10mg and 20mg options that suit compact pod devices.

And if you vape without nicotine, none of the above applies. The bottle is ready as it stands.

Sweet liquids and the coil question

There is a practical cost to sweet shop profiles that nobody mentions in the flavour description, and it is worth being straight about it.

Sweeteners are typically sugar alcohols such as sucralose. They do not burn cleanly. Under the sustained heat of a coil they caramelise onto the wire and the cotton, leaving a dark residue that dulls flavour and eventually starts producing a scorched note regardless of how much liquid is present. Confectionery styled liquids, sour ones included, tend to be more heavily sweetened than a straight fruit blend, so they take a heavier toll on coils.

Three things reduce the damage. Run your coil at the lower end of its stated range rather than the top, because heat is what drives the caramelisation. Take a moment between draws instead of chain vaping, which lets the wicking catch up. Change the coil at the first hint of a dull or slightly burnt taste rather than trying to squeeze another two days out of it, because a struggling coil ruins the flavour of good liquid.

Rinsing a used coil under a tap is not worth the effort. It rarely restores more than a fraction of the original performance and the drying time is longer than most people are willing to wait. Coils are the cheapest part of the hobby to replace, and our replacement coil range covers the common fittings.

One more point. Sweeteners also settle. Give the bottle a shake before every refill, not just after mixing, and you will get more consistent flavour from the first fill to the last.

Ordering, dispatch and who we will sell to

A single bottle at £6.99 sits under the free postage threshold, which kicks in once your basket exceeds £20. Three shortfills at this price come to £20.97 and clear it, and given the argument above about rotation, three is a reasonable number of bottles to own at once anyway. Below that figure, standard UK postage is charged.

Dispatch works on a straightforward cut off. Orders confirmed before 4pm Monday to Friday are packed and handed over the same day. Anything later, or placed at a weekend or on a bank holiday, goes out on the next working day. We do not hold stock back or split orders unnecessarily.

Authenticity is not something we treat as a marketing line. Fake e-liquid is a live problem in this market, and the packaging is easy to imitate. What is inside a counterfeit bottle has been through no notification process and nobody knows what it is. Every Yeti bottle listed here is 100% genuine and arrives sealed exactly as it left the manufacturer.

On age we are inflexible. This is an 18+ product, we run verification checks, and orders we cannot verify are cancelled rather than sent. Buying vaping products for someone under 18 is illegal and we will not knowingly be part of it. Keep e-liquid, devices and batteries out of reach of children and animals in the home.

Where this sits in the Yeti range

Brands are easier to judge by their range than by any one item in it. We stock 5 Yeti products, running from £6.99 to £10.99. That makes it a small, specialist range rather than a catalogue brand.

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

• Yeti Ice Cold 100ml at £6.99
• Yeti Summit Series 100ml at £8.99
• Yeti No Ice 100ml at £10.99
• Yeti Blizzard 100ml at £6.99

If a brand has worked for you once, its other lines are usually a safer bet than an unknown.

How it compares to the rest of the category

Judging a product in isolation is how people end up disappointed. We list 736 products in this category. At £6.99, this one sits in the middle of the market.

• 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.

The honest answer is that most vapers end up owning two formats, not one.

The running cost, worked out

The useful figure is not the shelf price but the running cost once you settle into a rhythm.

No puff rating is published for this listing, so we will not invent a per-puff figure.

• No multibuy runs on this line, so the deals page is where the savings are.
• 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.

Why the UK market looks like this

Some of what you see on the shelf is regulation rather than brand choice. UK rules cap nicotine at 20mg per ml, nicotine e-liquid bottles at 10ml, and prefilled pods and tanks at 2ml. That is why no retailer here sells a 50ml bottle of 20mg salt.

The single-use disposable ban reshaped the rest. 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.

We only list compliant stock sourced through UK distributors. This is an 18+ product and orders are verified before dispatch.

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.

These are small habits that pay back in flavour consistency.

Buying this as a first purchase

New to this format? Three decisions cover almost everything.

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 0mg. Heavier former smokers usually start high and step down.
3. Flavour. Pick two from different families rather than committing to one.

Everything else is preference rather than a decision that costs you money. The deals page is the cheapest way to try more than one at a time.

Delivery, returns and buying with confidence

Ordering is deliberately simple. Weekday orders placed before 4pm are dispatched the same day, and UK delivery is free once your basket reaches £20.00. Delivery choices, including tracked services, appear at checkout.

We cannot resell an opened consumable, so opened items are outside the returns policy. Faults and picking errors are resolved without argument. Sales are strictly 18+ and every order is age-verified before dispatch.

Nicotine is highly addictive, and nothing here is intended for non-smokers.

Reading puff counts and pack sizes honestly

Every headline figure in this category is generated under ideal conditions. This listing publishes no puff rating, and we will not invent one. That figure comes from laboratory testing with a consistent draw, not from someone using it on a cold morning at a bus stop. Your own total will differ, sometimes considerably.

The arithmetic only makes sense once you know the legal limits. UK rules cap a prefilled pod or tank at 2ml, and nicotine e-liquid bottles at 10ml. A five-figure puff rating therefore describes what a system delivers across all the pods you will work through, not what sits inside one pod on the shelf. Any brand claiming otherwise is describing a product that could not legally be sold here.

Treat it as a relative measure, never an absolute one. Comparing two products in the same class is fair. Budgeting your month on the strength of a rating is not. Cost per week, measured once you know your own pace, beats every figure on the box.

Building a rotation instead of buying one thing

Experienced vapers rarely buy one flavour in bulk, and new ones almost always do. 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.

The wider category is the place to find a contrasting profile if this line has no siblings.

Multibuy offers make this cheap to do, and they can be mixed across flavours.
