Mr Blue Flavour Profile

Mr Blue is the manufacturer flavour name for a blue mixed-berry style profile — the kind of vivid, sweet, slightly tangy berry direction that many adult vapers associate with blue raspberry-flavoured drinks and confectionery rather than a single identifiable natural fruit. It is not a specific named berry blend; the "blue" in the name indicates the flavour concept and character rather than any fixed ingredient list. The overall profile is sweet, vivid, and clearly fruit-forward throughout the draw, with the blue-berry concept as its primary identity.

On the inhale, Mr Blue delivers a full, sweet blue mixed-berry character — rounded and immediately recognisable as a blue-style berry flavour, with the vivid, slightly bold quality that distinguishes this flavour direction from a plainer, more restrained fresh berry option. It sits closer to the candy-adjacent end of the berry spectrum than the fresh or natural end — vivid and punchy rather than subtle or delicate.

On the exhale, a slight tangy brightness adds definition and prevents the profile from reading as a flat, uncomplicated sweetness. Many adult vapers describe this bright, slightly tangy close as what makes the Mr Blue profile feel lively and interesting to return to across a longer session. The overall sweetness level is medium to high — a clearly sweet profile that suits adult vapers who enjoy vivid, fruit-forward options without being at the extreme end of the confectionery spectrum.

Regarding cooling: no cooling or menthol element is confirmed for this flavour. If a cooling finish is important to your purchase decision, check the current product listing or contact Vapourcore before ordering. The flavour profile described above is based on the blue mixed-berry direction indicated by the name.

Who Mr Blue Is Best For

• Adult vapers who enjoy vivid blue mixed-berry or "blue razz"-style flavour profiles. Mr Blue is built around the blue berry flavour concept that many adult vapers find immediately appealing and distinctively recognisable. If you enjoy blue-style berry nic salts and want a consistent, full-flavoured option in this direction in a 10ml refillable format, this is a natural match.
• Those who prefer medium-to-high sweetness fruit profiles. Mr Blue is a clearly sweet, fruit-forward option. It suits adult vapers who enjoy vibrant, vivid fruit sweetness rather than those looking for a lower-sweetness or more restrained profile.
• Adult vapers who find plain single-note berry options too simple. The blue mixed-berry concept, with its slightly tangy brightness on the exhale alongside the primary sweetness, gives the draw more movement and interest than a flat single-note fruit profile would produce across a session.
• Those switching from disposable vapes to a refillable pod kit. Mr Blue-style blue berry flavours have been popular in the disposable vape format, and the Crystal Clear Bar Salts range is designed to bring that kind of vivid, familiar flavour direction into a refillable 10ml nic salt setup. Adult vapers who have made the switch can access comparable profiles at a considerably lower ongoing cost per session than running disposables.
• Adult vapers who want a fruit-forward option in the Crystal Clear Bar Salts range. The broader Crystal Clear Bar Salts e-liquid range covers 35+ flavours, with Mr Blue occupying the vivid, sweet blue-berry direction within a varied flavour library.

10mg vs 20mg: Which Strength Should I Choose?

Crystal Clear Bar Salt Mr Blue is available in 10mg/ml and 20mg/ml nicotine salt. The Mr Blue flavour profile is identical between the two — only the nicotine concentration differs. Selecting the correct strength before adding to your basket is important, as it determines the product dispatched to you.

• 10mg/ml — typically preferred by adult vapers who vape more frequently throughout the day, those who have progressively reduced their nicotine intake over time, or those who find 20mg delivers more nicotine per draw than they currently want. Many adult vapers find 10mg comfortable and consistent across longer, sustained sessions.
• 20mg/ml — typically preferred by adult vapers who vape in shorter or less frequent sessions, those who want a more pronounced nicotine delivery from each draw, or those who have recently moved from a product at a higher nicotine level. Many adult vapers find 20mg more satisfying with fewer draws per session.

No medical guidance is offered. If you are uncertain which strength to start with, beginning at 10mg and adjusting from there is a commonly followed approach among adult vapers.

Best Devices for Mr Blue Nic Salt (MTL)

Crystal Clear Bar Salt Mr Blue is formulated for use in refillable MTL pod kits — compact, lower-powered devices designed for a Mouth-to-Lung draw style. These devices produce a tighter, more focused draw and lower vapour output than sub-ohm or direct-lung hardware, and they are well-matched to nicotine salt formulations at 10mg and 20mg. Using a 20mg/ml nicotine salt in a high-powered sub-ohm device is generally not recommended and may produce a draw that many adult vapers find uncomfortable.

Higher-resistance MTL coils are commonly used alongside nic salt e-liquids in refillable pod kits, and they suit the lower power output and draw style that an MTL nic salt profile is designed for. Always check your device manufacturer's guidance on recommended e-liquid types and coil specifications before filling, as compatibility varies between devices. For a selection of refillable MTL pod kits suited to nic salt e-liquids, the refillable pod vape kits collection covers options across a range of price points.

How to Use Crystal Clear Bar Salts in a Refillable Pod Kit

1. Check device compatibility. Confirm your pod kit is designed for nic salt e-liquids and MTL vaping before filling. Do not use in a high-powered sub-ohm or direct-lung device.
2. Fill the pod. Open the fill port and add the e-liquid carefully, keeping below the maximum fill line marked on the pod. Reseal the fill port immediately after filling.
3. Prime the coil. Allow the filled pod to sit for at least five minutes before the first draw. This gives the e-liquid time to fully saturate the coil wick and significantly reduces the risk of a dry or burnt first hit.
4. Start gently. For the first few draws on a new coil, use shorter, more measured inhales to allow the coil to bed in before progressing to full MTL draws.
5. Pace your draws. Allow a few seconds between draws, particularly on a new coil or when the e-liquid level is running low, to let the wick re-saturate and prevent a burnt or degraded taste.
6. Refill before running dry. Top up the pod before the e-liquid level drops too low. Running the coil dry will damage the wick and reduce flavour quality, typically requiring a coil or pod replacement to restore performance.
7. Store correctly. Keep the bottle upright in a cool, dry location away from direct sunlight. Replace the cap after each use. Keep all nicotine-containing products out of reach of children and pets at all times.

Frequently Asked Questions

What does Crystal Clear Bar Salt Mr Blue taste like?

Mr Blue is the manufacturer flavour name for a vivid, sweet blue mixed-berry style profile — the kind of bold, immediately recognisable blue-berry character that many adult vapers associate with blue raspberry-flavoured drinks and confectionery rather than a single natural berry. The inhale delivers full, sweet blue-berry sweetness; the exhale carries a slight tangy brightness that lifts the profile and adds definition to the finish. It is a medium-to-high sweetness option that sits closer to the candy-adjacent, vivid end of the berry spectrum than a subtle fresh-fruit option would.

Is Mr Blue more sweet or sharp?

Mr Blue leans sweet — the blue mixed-berry character is the dominant quality throughout the draw, and it reads as a clearly sweet, fruit-forward profile. There is a mild tangy brightness on the exhale that adds some definition and prevents the flavour from sitting as a completely flat sweetness, but this is a brightness rather than a sharpness or tartness. Adult vapers who enjoy vivid, medium-to-high sweetness berry profiles are most likely to find it well-suited; those who prefer low-sweetness or restrained options may find it fuller and sweeter than they expect.

Does Mr Blue include ice, cooling, or menthol?

No cooling or menthol element is confirmed for Crystal Clear Bar Salt Mr Blue. Based on the flavour name and concept — a blue mixed-berry style profile — it is described here as a warm, fruit-forward option without a confirmed cooling finish. If a cooling sensation is important to your purchase decision, check the current product listing or contact Vapourcore before ordering to confirm the exact formulation. Do not assume a cooling element is present based on the name alone.

What is the difference between 10mg and 20mg?

Both the 10mg/ml and 20mg/ml options deliver exactly the same Mr Blue flavour profile. The only difference is the nicotine concentration. 10mg is typically preferred by adult vapers who vape frequently or find 20mg more than they currently need per draw. 20mg is typically preferred by those who vape less often or want a stronger nicotine delivery per draw. No medical guidance is offered here — the right choice depends on your current vaping habits and preferences. If you are unsure, starting at 10mg and adjusting is a commonly followed approach.

Can I use Mr Blue nic salt in a sub-ohm device?

This is not recommended. Crystal Clear Bar Salts are formulated for refillable MTL pod kits and low-wattage devices, not for high-powered sub-ohm or direct-lung setups. Using a 20mg/ml nicotine salt in a sub-ohm device may produce a draw that many adult vapers find uncomfortably harsh or intense. Always verify your device's recommended e-liquid type and coil specification before filling. If you are unsure whether your device is MTL-appropriate, check the manufacturer's documentation or seek guidance before use.

How long does a 10ml bottle of Mr Blue last?

Bottle life varies based on individual draw length, frequency, and inhalation style — there is no single figure that applies universally, and no guaranteed puff count is claimed for this product. As a general point of reference, a 10ml nic salt bottle typically delivers considerably more than the 2ml capacity of a standard disposable pod, though the exact difference depends on personal usage habits. If you are switching from disposables, you may find a 10ml bottle lasts noticeably longer than you expect based on prior single-use experience.

What should I do if Mr Blue tastes muted or burnt?

A muted or faded flavour is most commonly caused by a pod that is running low on e-liquid or a coil that is nearing the end of its usable life — top up or replace accordingly. A burnt taste typically indicates the coil was not given enough time to prime after filling; always allow at least five minutes after filling a new pod before drawing. If the burnt taste develops mid-session rather than at the start, the coil may be depleted and should be replaced. Chain vaping without pauses can also cause temporary coil overheating.
