Crystal Galaxy Focus 2 Refill Pack – Blueberry Raspberry/Blueberry Sour Raspberry

Two flavours, one pack, two different moods

The Crystal Galaxy Focus 2 Refill Pack pairs Blueberry Raspberry with its sharper sibling, Blueberry Sour Raspberry, and the point of putting them together isn't to give you two versions of the same thing. It's to give you a genuine choice depending on what you fancy in the moment. Blueberry Raspberry is the calmer of the two, a rounded, fruity blend where blueberry leads and raspberry adds just enough tang to stop things tasting flat. Blueberry Sour Raspberry takes that same base and turns the dial up, adding a proper sour candy snap on the inhale that fades into sweetness rather than the other way round. Vaped back to back, the difference is obvious within the first pull of each.

Blueberry Raspberry: the smoother of the two

First inhale here is soft and rounded, blueberry sitting comfortably at the front with none of the sharpness you'd get from raspberry on its own. As the vapour develops mid pull, raspberry comes through underneath, adding brightness rather than bite. There's no sourness to speak of in this side of the pack, just a clean, straightforward berry flavour that leans sweet without tipping into syrupy. The exhale is gentle, leaving a light fruity note that fades quickly rather than clinging to the back of the throat. This is the flavour for when you want something familiar and easy, not a flavour that demands your attention.

Blueberry Sour Raspberry: the one with the twist

This is where the pack earns the word sour in its name. The first pull hits with a genuine tang right at the front, closer to a sour sweet than a soft fruit, before the same blueberry base underneath softens the landing. Mid vape, the sourness and sweetness trade places a couple of times rather than settling into one lane, which is what makes this side more interesting to vape for longer stretches. The exhale carries a slightly puckering finish that fades into sweetness over a second or two, an aftertaste that's much more memorable than its calmer sibling. If you've ever liked sour berry sweets from a pick and mix, this is the closest a vape in this pack gets to recreating that specific sensation.

Which one suits which mood

Blueberry Raspberry works best when you want a flavour that stays in the background, during a busy morning, at your desk, or anywhere you don't want the vape itself competing for your attention. Blueberry Sour Raspberry suits the opposite situation, when you actually want the flavour to be part of the experience, on a break where you've got a few minutes to actually notice it, or in the evening when a bit of sharpness feels welcome rather than jarring. Neither one is objectively the better flavour. It genuinely comes down to whether you want the vape to sit quietly or make itself known.

Switching between the two without either one going stale

Having both in one pack solves a problem that a single flavour pack doesn't: palate fatigue. Vape only the sweeter side for a full day and it can start to taste a bit one note by the evening. Vape only the sour side and the tang can start to feel slightly relentless after enough sessions in a row. Alternating between the two, even within the same day, keeps both tasting sharper than they would in isolation. A common pattern among vapers who get on well with this pack is sour in the morning to wake the palate up, then the smoother blend later in the day when something gentler suits the mood better. There's no fixed rule here, but the contrast is exactly what the pairing is designed to offer.

How they compare to a standard single berry vape

Against a plain blueberry or raspberry vape, both flavours in this pack feel more finished, because a single fruit on its own tends to taste a bit one dimensional after the first few pulls. Blueberry Raspberry is the fairer comparison to a typical mixed berry vape, similar in sweetness but tighter in focus since it's only working with two fruits rather than four or five. Blueberry Sour Raspberry doesn't really have a direct equivalent among standard fruit vapes, since the sour candy element pushes it closer to a sweets inspired flavour than a straight fruit one. That's really its selling point within the pack, it isn't trying to taste like fresh fruit, it's aiming for the sweet shop instead.

Getting the truest taste from each refill

Sour flavours in particular are sensitive to how a pod is treated. Let a freshly filled pod sit for a minute before pulling on it, since the sour top note needs the liquid to properly saturate the coil or it can taste muted on the very first draw. Store both refills at room temperature rather than anywhere too warm, since heat softens the sourness in Blueberry Sour Raspberry faster than it affects the calmer Blueberry Raspberry side. And if you're alternating between the two, give your palate a minute or two of plain air between switches, since jumping straight from one to the other can make the second flavour taste muddled rather than distinct.

Which flavour in the pack is sweeter?

Blueberry Raspberry is the sweeter, more rounded of the two. Blueberry Sour Raspberry starts with a tangy edge before settling into sweetness on the finish.

Can I vape both flavours from the same pack on the same day?

Yes, and many people prefer it that way. Alternating between the two keeps each one tasting distinct rather than letting either flavour become background noise.

Does the sour side taste artificial?

It's closer to a sour sweet than an artificial chemical taste, with the tang settling into sweetness rather than staying sharp for the whole pull.
