Bar Juice 5000 Nic Salts – Mr Blue

Mr Blue Bar Juice 5000 Nic Salts: the Mystery Blue Everyone Ends Up Loving

Ask ten vapers what Mr Blue tastes of and you will get ten slightly different answers, and that is precisely why it works. This is the classic blue mystery flavour, a cool medley of blue fruits and sweets that refuses to name itself, and it has become a cult favourite for exactly that reason. As a Bar Juice 5000 nic salt e-liquid, it delivers that moreish, hard-to-place blue character in a smooth pour that keeps you guessing and keeps you coming back.

Decoding the taste

The first inhale is unmistakably blue. There is a sweet blue raspberry note up front, that fairground slushie and blue sweet flavour that so many people recognise instantly even if they cannot put a finger on the exact fruit. Alongside it sits a softer, rounder berry note, closer to blueberry, which gives the opening some depth rather than leaving it as pure candy. It is sweet, bright and immediately familiar in that nostalgic, hard-to-name way.

Through the mid-vape, a gentle cooling effect drifts in. It is not a heavy menthol wall, more a light chill that lifts the berries and gives the blend that crisp, refreshing edge Mr Blue is known for. The nic salt base keeps everything smooth here, so despite the sweet, candy-like character the draw stays easy on the throat. This is the stretch where the mystery really lives, as the blue raspberry, the soft berry and the cool note weave together into something that is more than the sum of its parts.

The exhale is clean and cool, leaving a sweet blue-fruit trail with just a touch of tang to tidy up the finish. There is no cloying stickiness afterward, which is a big reason it vapes so comfortably over a long session. That refreshing, slightly icy close is what makes one draw roll straight into the next.

Who it is for and when it lands best

Mr Blue appeals to vapers who love sweet, fruity blends with a cool twist, and especially to anyone with a soft spot for blue raspberry and slushie-style flavours. If your favourites tend to be candy fruits with a refreshing edge rather than realistic single fruits or heavy menthols, this is right up your street.

Its balanced sweetness and light chill make it a strong all-day option, easy to keep in your kit as a reliable default. It really shines on warmer days, when that cool blue-slushie quality feels genuinely refreshing, though it is just as satisfying as a bright, mood-lifting vape any time you fancy something sweet and cheerful. It is the kind of flavour that fits equally well on a summer afternoon, a night out or a quiet evening at home.

Comparisons and rotation tips

Compared with a straightforward blueberry, Mr Blue is sweeter, candy-driven and cooler, trading realism for that fun fairground character. Set against a blue raspberry with no ice, this version feels crisper and more refreshing thanks to its light chill. And next to a heavy menthol berry, Mr Blue is friendlier and more mellow, since the cooling here supports the fruit rather than dominating it.

Even a crowd-pleaser like this benefits from company in your rotation. To keep it tasting sharp, pair it with a flavour from a different family, such as a warm cola, a tropical mango or a dessert profile, so your palate does not settle into the blue too comfortably. If you love the sweet-and-cool theme, you could alternate with a red berry or a mixed fruit ice for variety while staying in a similar mood. Switching between Mr Blue and something citrus or menthol-forward also keeps the blue notes vivid each time you return.

Practical notes to keep it at its best

Sweet, candy-style blue flavours carry a fair amount of sweetener, so your coil can gunk up a little faster than it would on a plain menthol. Changing your coil or pod a touch more regularly keeps the blue raspberry and berry notes crisp and stops them turning dull or muted. As always, let a fresh coil soak for a few minutes before the first draw so you do not scorch that delicate sweet top note.

Mr Blue tastes its best when the liquid is fresh and kept out of direct sunlight and heat, which protects both the candy sweetness and the subtle cool note. Room-temperature liquid and steady, unhurried draws let the light chill and the layered blue fruits show themselves properly, whereas rapid back-to-back pulls can flatten that refreshing edge. Look after it that way and every session keeps the crisp, mysterious blue character that made you reach for it in the first place.
