IVG 70/30 Shortfill E-Liquid 100ml – Rainbow Blast

Rainbow Blast in 100ml: a whole bag of fruit sweets in shortfill form

Some flavours try to be elegant. Rainbow Blast does not, and that is exactly why people love it. This is the vape equivalent of tipping out a bag of soft, chewy rainbow sweets and eating a handful at once, all the fruity colours tumbling over each other in one bright, unapologetic mouthful. Delivered as an IVG 70/30 Shortfill E-Liquid in a generous 100ml bottle, it is built for people who want that big, cheerful candy-fruit experience with plenty of cloud to carry it.

The 70/30 VG to PG blend is the key to how this flavour feels in the mouth. That higher vegetable glycerine content gives Rainbow Blast a soft, rounded, cloud-forward delivery, which suits a sweet flavour perfectly. Instead of a sharp, thin candy hit, you get a plush, warm-and-sweet vapour that fills the room. As a shortfill it arrives nicotine-free, leaving space for you to add nic shots to your preferred strength, and the 100ml size means a genuinely long-lasting supply once mixed.

Taste profile: the first draw, the middle and the finish

The opening inhale is pure fruit-sweet joy. It hits sweet and immediately multi-layered, with no single fruit allowed to dominate. You catch flashes of strawberry, orange, lemon and something berry-ish all at once, exactly like the moment a mixed handful of chewy sweets hits your tongue. It is bright, sugary and instantly recognisable, the kind of first draw that makes you smile before you have even thought about the individual notes.

Through the mid-vape the flavour settles into its groove. This is where the soft 70/30 body really pays off, because the sweetness turns creamy and rounded rather than sharp. The citrus elements add a gentle zing that keeps the whole thing from becoming flat, while the berry and red-fruit notes provide the deep, chewy-sweet backbone. It genuinely tastes like confectionery rather than fresh fruit, which is precisely the target it is aiming for.

On the exhale you get a big, sweet, fruity cloud and a lingering candy-shop aftertaste that sits pleasantly on the lips. It is sugary right to the end, so if you love a flavour that leaves you tasting sweets between draws, this delivers in full. The finish is warm and generous rather than crisp or dry, which reinforces the whole comforting, treat-yourself mood of the liquid.

Who it is for and the best moments to vape it

Rainbow Blast is squarely aimed at the sweet-tooth crowd. If you grew up loving chewy fruit sweets and you want a vape that recreates that feeling, this is an obvious pick. It also suits sub-ohm and direct-to-lung vapers who enjoy big clouds, since the higher VG blend and 100ml format are built for exactly that kind of setup. Newer vapers moving up from a simple pod device to something with more airflow will find it a very forgiving, very enjoyable place to start with shortfills.

Mood-wise, this is a daytime pick-me-up. It is bright, fun and energising, the sort of flavour you reach for when you want a little lift rather than a quiet, contemplative vape. It works brilliantly on a long drive, during a gaming session, on a sunny afternoon, or any time you fancy something that feels like a small, sweet reward. It is less suited to pairing with food, since its bold candy character tends to overrun subtler tastes.

• Best mood: upbeat, playful, in need of a sweet lift.
• Best setting: sub-ohm kit with decent airflow for full clouds.
• Best occasion: daytime all-day vaping when you want fun over subtlety.

How it compares and what to keep alongside it

Against a single-fruit shortfill, say a straight strawberry or a lone mango, Rainbow Blast is far busier and sweeter. Single fruits aim for realism, this aims for the sweet shop. Compared with a slushie or ice-fruit liquid it is warmer and rounder, because there is no cooling menthol to sharpen it. And next to a dessert or custard flavour it is lighter and more playful, all bright fruit-candy rather than rich cream.

Very sweet, layered flavours like this are the ones most likely to cause palate fatigue if you vape nothing else, simply because your taste buds adjust to the constant sugar. The fix is to keep a contrasting liquid in rotation. A crisp menthol, a tart lemon, or a clean single fruit makes an excellent partner, resetting your palate so Rainbow Blast tastes as vivid on the tenth vape as it did on the first. Something creamy also works as an occasional change of pace. What you want to avoid is running several sweet mixed-candy liquids back to back, because they tend to blur into one indistinct sugar rush.

Practical notes: mixing, steeping, storage and value

As a shortfill, this liquid is nicotine-free out of the bottle, so if you want nicotine you add nic shots to reach your chosen strength before use. Give the bottle a proper shake after mixing so the liquid is fully blended, then, if you can, let it stand for a short while. A brief settle helps a busy multi-fruit candy flavour marry together and taste its best, and many people find sweet blends like this improve slightly after a day or two of steeping.

To keep the flavour at its brightest, store the bottle upright somewhere cool and dark, away from sunlight and heat, both of which can dull sweet fruit notes over time. On kit, a fresh coil always shows a sweet, complex liquid like this at its cleanest, since high-VG sweet liquids can gunk coils faster than plainer flavours. At 100ml the value is strong, giving you a long-lasting supply that comfortably outlasts a stack of small disposables while letting you dial in your own nicotine level and inhale style.

Who should think twice

If you find very sugary vapes overwhelming, or you prefer realistic single fruits, cool menthols or tobacco, Rainbow Blast will probably be too sweet and too candy-forward for you. It is also less ideal for tight mouth-to-lung pod users who want minimal cloud, given its high-VG, cloud-heavy design. This is a flavour that knows exactly what it is: loud, sweet and fun, best enjoyed by people who want precisely that.

Rainbow Blast FAQ

Does Rainbow Blast taste like real fruit or like sweets?

Firmly like sweets. It is designed to recreate a handful of chewy rainbow fruit candies rather than fresh produce, so expect bright, sugary, layered confectionery notes rather than a true-to-life single fruit. That candy-shop character is the whole appeal for its fans.

Do I need to add nicotine to a shortfill?

Only if you want it. The bottle comes nicotine-free with headroom left in the 100ml so you can add nic shots to reach your preferred strength, or leave it as zero nicotine if that is what you use. Nicotine products are strictly for over-18s, and salt-based nicotine in the UK is capped at 20mg/ml.

Why does it feel so smooth and cloudy?

That comes down to the 70/30 VG to PG ratio. The higher vegetable glycerine content gives a softer throat feel and much bigger clouds, which is ideal for a sweet flavour and best enjoyed on a sub-ohm, direct-to-lung setup with good airflow.
