Best Blueberry Sour Raspberry E-Liquid UK 2026: Brand Comparison & Review

Blueberry sour raspberry is one of the most popular e-liquid flavours in the UK right now. Originally made famous by the SKE Crystal Bar disposable, the flavour profile has become so iconic that virtually every major e-liquid brand now produces its own version — and they’re not all created equal.

The appeal is easy to understand: ripe, sweet blueberries paired with sharp, tangy raspberries and a subtle sour edge that keeps it interesting all day. It’s fruity without being sickly, complex enough to stay engaging, and it’s become the go-to recommendation for anyone transitioning from disposables to a refillable pod kit or sub-ohm device.

At White Vape Co, we stock blueberry sour raspberry from several brands across nic salts, 100ml shortfills and longfills. We’ve vaped them all extensively — here’s how they compare, and which ones we think are worth your money.

What Makes a Great Blueberry Sour Raspberry E-Liquid?

Before diving into individual brands, it’s worth understanding what separates a good blueberry sour raspberry from a great one. The best versions nail three things: a distinct blueberry note that tastes like actual fruit rather than artificial candy, a sharp raspberry that provides genuine tartness, and a sour finish that adds depth without overpowering the fruit. The balance between sweet and sour is where most brands either succeed or fall short.

You also want consistency — a flavour that tastes the same on the first puff as it does halfway through a pod. Cheap versions tend to lose their sour edge quickly, leaving you with a flat, generic berry taste by the end of the bottle.

The Brands We Stock: Head-to-Head Comparison

1. Mix Labs Blueberry Sour Raspberry — Our Top Pick

Available as: Nic Salt (10ml) | 100ml Shortfill | Longfill by NIXER

Mix Labs consistently delivers some of the best disposable-inspired flavours in the refillable market, and their blueberry sour raspberry is no exception. The blueberry is prominent and natural-tasting, the raspberry has genuine bite, and the sour element lingers on the exhale without being harsh. It’s a well-rounded, satisfying vape that works brilliantly in pod kits.

The nic salt version is available in 10mg and 20mg strengths with a 50/50 VG/PG ratio — ideal for devices like the OXVA Xlim Go 2. The 100ml shortfill gives you the same flavour profile in a 70/30 mix for sub-ohm tanks and higher-powered devices, while the longfill by NIXER offers excellent value if you prefer to add your own nicotine shots.

Flavour accuracy: ★★★★★ — The closest match to the original Crystal Bar flavour we’ve found in refillable form.
Throat hit: Smooth at both strengths, no harshness.
All-day vape? Yes — the sour edge prevents flavour fatigue.

2. Elfliq Blueberry Sour Raspberry

Available as: Nic Salt (10ml) — browse Elfliq range

Elfliq is the official nic salt line from Elf Bar, and their blueberry sour raspberry carries that recognisable Elf Bar DNA. If you loved the original Elf Bar 600 or Elf Bar BC5000 version of this flavour, Elfliq is the closest you’ll get in a refillable e-liquid.

The flavour leans slightly sweeter than Mix Labs, with the blueberry taking centre stage and the sour raspberry playing more of a supporting role. It’s smooth, well-made, and the flavour consistency is excellent — you get the same taste from start to finish. Available in 10mg and 20mg nic salt with a 50/50 ratio.

Where Elfliq falls slightly behind Mix Labs is in complexity. The sour element is more subtle, which makes it a touch less interesting over extended vaping sessions. That said, if you prefer a sweeter, less tart profile, Elfliq might actually be your better choice.

Flavour accuracy: ★★★★☆ — Faithful to the Elf Bar original but sweeter than the Crystal Bar profile.
Throat hit: Very smooth, slightly softer than Mix Labs.
All-day vape? Yes, though the sweetness may tire some palates.

3. Imp Jar Blueberry Sour Raspberry

Available as: Nic Salt (10ml) | Imp Jar MAX 60ml Shortfill

Imp Jar has built a strong reputation for producing bold, punchy flavours at competitive prices. Their blueberry sour raspberry is one of their bestsellers for good reason — it’s intense, flavourful, and doesn’t hold back on the sour element.

Compared to Mix Labs and Elfliq, Imp Jar pushes the sour note harder. The raspberry is sharper, the blueberry is darker, and the overall profile is more candy-like than fruity. If you want a blueberry sour raspberry that really hits you with that tangy, fizzy sensation, Imp Jar delivers. The Imp Jar MAX 60ml shortfill is also excellent value, giving you a bigger bottle with the same bold flavour.

Flavour accuracy: ★★★★☆ — More intense and candy-forward than the original Crystal Bar profile.
Throat hit: Slightly more noticeable than the other two, especially at 20mg.
All-day vape? Depends on your preference — the intensity suits some vapers perfectly, while others may want to rotate.

How Do the Competitor Brands Compare?

While we stock the three brands above because we believe they offer the best quality and value, it’s worth knowing how the wider market stacks up.

SKE Crystal Original Nic Salt

SKE Crystal is where blueberry sour raspberry became a phenomenon. Their nic salt version is faithful to the original Crystal Bar flavour — sweet, balanced, and instantly recognisable. However, it tends to be pricier than Mix Labs and less widely available in independent shops. If you’re chasing that exact Crystal Bar nostalgia, it’s worth trying, but Mix Labs gets you 95% of the way there at a better price point.

Bar Juice 5000

Bar Juice produces solid disposable-replica nic salts, and their blueberry sour raspberry is competent. The flavour sits somewhere between Elfliq and Mix Labs in terms of sweetness, but lacks the sour punch that makes the best versions special. It’s a safe choice but not a standout.

IVG

IVG’s version (often labelled Blue Raspberry or similar variants) is well-made and consistent but tends to lean more heavily toward blue raspberry candy than the distinct blueberry-plus-sour-raspberry profile. If you want a broader berry flavour, IVG is fine, but it’s not the most accurate representation of this specific flavour.

Doozy Seriously Salty Fusionz

Doozy doesn’t produce a direct blueberry sour raspberry, but their Cherry Sour Raspberry hits similar notes with a cherry twist. If you love the sour raspberry element but want something different, Doozy’s Fusionz range is worth exploring.

Quick Comparison Table

Brand	Sweetness	Sour Intensity	Best For	Formats Available
Mix Labs ⭐	Medium	Strong	Best all-rounder, closest to Crystal Bar	Nic salt, 100ml shortfill, longfill

Our Verdict

Mix Labs Blueberry Sour Raspberry is our top recommendation. It delivers the most accurate, well-balanced version of this flavour we’ve tested — faithful to the original Crystal Bar profile with enough sour complexity to keep it interesting all day. The fact that it’s available as a nic salt, 100ml shortfill and longfill means you’re covered regardless of your setup.

If you prefer a sweeter, smoother experience, go with Elfliq. If you want maximum intensity and don’t mind a bolder, more candy-forward profile, Imp Jar won’t disappoint.

All three are available on our multi-buy deals — stock up and save.

Best Pod Kit for Blueberry Sour Raspberry Nic Salts

The device you use makes a big difference to how any e-liquid tastes. For blueberry sour raspberry nic salts, we recommend a dedicated MTL pod kit with a 0.6ohm or 0.8ohm coil — this resistance range brings out the fruit and sour notes without muting them.

Our top pick is the OXVA Xlim Go 2 — its adjustable airflow and UniTech 2.0 coil technology extract maximum flavour from every puff. Pair it with a pack of Xlim EZ 0.6ohm pods and your favourite blueberry sour raspberry nic salt for the best possible experience. Or grab the complete Xlim Go 2 Starter Bundle with pods and nic salts included.

Frequently Asked Questions

What does blueberry sour raspberry e-liquid taste like?

Blueberry sour raspberry combines sweet, ripe blueberries with tangy raspberries and a sour finish. The flavour was popularised by the SKE Crystal Bar disposable and has become one of the UK’s most searched vape juice profiles. The best versions balance fruit sweetness with a sharp, slightly fizzy sour edge that keeps it interesting throughout the day.

Which brand makes the best blueberry sour raspberry nic salt?

In our testing, Mix Labs produces the most accurate and well-balanced blueberry sour raspberry nic salt. It’s the closest match to the original Crystal Bar flavour in refillable form. Elfliq is a great alternative if you prefer something sweeter, while Imp Jar delivers the most intense sour hit.

Is blueberry sour raspberry the same as blue raspberry?

No — they’re different flavour profiles. Blue raspberry is a single candy-style flavour inspired by blue slush drinks. Blueberry sour raspberry is a dual-fruit blend with distinct blueberry and raspberry notes plus a sour twist, originally made famous by the SKE Crystal Bar. Both are popular, but blueberry sour raspberry tends to be more complex and less one-dimensional.

What nicotine strength should I choose?

If you’re switching from smoking or moving away from disposables, start with 20mg nic salt for the closest experience to a cigarette or disposable vape. If you’re already vaping and want a lighter hit, 10mg nic salt is smooth and satisfying. For sub-ohm devices, use the shortfill version with nicotine shots added to your preferred strength.

Can I get blueberry sour raspberry as a shortfill?

Yes — Mix Labs 100ml shortfill and Imp Jar MAX 60ml shortfill are both available. Shortfills are nicotine-free and come with space to add nic shots, making them ideal for sub-ohm tanks and higher-powered devices where you want bigger clouds and bolder flavour.

What’s the best pod kit for blueberry sour raspberry e-liquid?

We recommend the OXVA Xlim Go 2 with 0.6ohm pods for the richest flavour from blueberry sour raspberry nic salts. Its adjustable airflow and smart wattage detection are perfectly suited to 50/50 e-liquids. Check our Best Vape Starter Kits UK 2026 guide for a full comparison of beginner-friendly devices.
