Crystal Pro CP 10K Refill Pack – Blueberry Raspberry

Two Berries, One Draw

Blueberry and raspberry get paired together a lot in vaping, but the CP 10K Refill Pack handles the combination with more restraint than most. The blueberry leads on the inhale, round and slightly waxy in the way fresh blueberries taste rather than the sharper blueberry sweet shop version, and the raspberry doesn't try to compete with it immediately. Instead it arrives a beat later, adding a tartness that cuts through the blueberry's roundness before either flavour fully settles.

What stands out is that neither fruit gets buried. A lot of dual berry vapes end up tasting like one generic purple flavour once you're a few puffs in, but here you can still pick out where the blueberry ends and the raspberry starts, particularly if you're paying attention on a slower draw. The balance shifts slightly as you go through a session too, with the blueberry feeling more dominant early on and the raspberry's tartness becoming more noticeable as your palate adjusts to the sweetness.

The Middle and the Finish

Mid vape, the two fruits start to properly merge into something closer to a berry compote than two separate flavours, warm and slightly jammy rather than sharp or artificial. This is where the flavour is arguably at its best, past the initial hit but before any fatigue sets in, when the blueberry and raspberry have settled into a single rounded profile that still carries hints of both.

The exhale carries more raspberry than blueberry, a light tartness on the back of the throat that keeps the whole thing from feeling too sweet or heavy. Aftertaste is clean, fading within a handful of seconds rather than lingering, which makes it easy to keep going back for another draw without feeling like your mouth is coated in anything. It's a refined take on a combination that, on cheaper mixes, often ends up either too sweet or too sour with nothing in between.

Best Suited To

This flavour tends to appeal to vapers who like fruit but want something with a bit of tartness rather than pure sweetness, closer to a berry dessert than a fizzy sweet. If bubblegum or cola style flavours feel too artificial for your taste, blueberry raspberry is a more natural feeling alternative that still delivers plenty of flavour.

It works well across most of the day, though it particularly suits mid morning or early afternoon use, when the tartness feels refreshing rather than heavy. Some vapers find very sweet, dessert style flavours a struggle first thing, and this one sits at a comfortable middle ground, sweet enough to feel indulgent, tart enough to feel light.

• Suits vapers who prefer natural feeling fruit over candy sweet profiles.
• A good mid session flavour, sitting between sharp citrus and heavy dessert vapes.
• Refill format means you can top up as needed rather than committing to a full disposable's puff count in one flavour.

Comparing It to Other Berry Mixes

Against a straight blueberry pod, this one has more brightness and less of the slightly flat, one note sweetness that pure blueberry vapes can fall into over a long session. Against a straight raspberry, blueberry raspberry is rounder and less sharp, the blueberry taking the edge off the raspberry's tartness so it doesn't become fatiguing as quickly on its own.

Compared with a mixed berry blend that throws in strawberry or blackberry as well, this combination is more focused. Two fruits rather than four or five means each one stays distinct, whereas broader berry mixes often blur into a single generic berry taste after the first few draws. If you like the idea of mixed berry but find those blends muddled, this narrower pairing is usually a clearer, more satisfying option.

To avoid the flavour going flat over repeated refills, it's worth switching in something from outside the berry family every so often. A citrus or a menthol refill breaks the pattern and resets your palate, so the next blueberry raspberry refill tastes as vivid as the first one did rather than blending into background sweetness.

Getting the Truest Berry Taste

Because this is a refill pack rather than a sealed disposable, freshness depends partly on how the liquid is stored once opened. Keeping the bottle upright, sealed tightly between refills, and out of direct sunlight or heat helps preserve both the blueberry's roundness and the raspberry's tartness, since both fade at different rates if the liquid is left exposed to warm conditions.

A gentler draw tends to bring out the layered quality of this flavour more than a fast, hard pull, which flattens the distinction between the two fruits into one general berry sweetness. If you're refilling little and often rather than filling right up, you'll also generally get a fresher tasting result than letting a tank sit half full for several days between top ups.

Which fruit is more noticeable, the blueberry or the raspberry?

Blueberry tends to lead on the inhale while raspberry comes through more on the exhale, so which one feels more dominant can depend on your draw style and how deeply you inhale.

Does this flavour work well as an all day refill, or is it better for shorter sessions?

It's balanced enough to work across a full day, though many vapers find it most enjoyable when rotated with a different flavour family every so often rather than refilled continuously without a break.

Will the nicotine strength affect how the flavour tastes?

As with most nic salt e liquids, higher strengths can slightly mute delicate fruit notes compared to lower strengths, so if flavour clarity matters most to you, it's worth trying a lower strength within the UK's 20mg/ml limit where suitable for your needs.
