IVG Pro 12 Starter Kit – Blue Sour Raspberry

Sour first, sweet second, that's the whole point

The first thing you'll notice about Blue Sour Raspberry on the IVG Pro 12 is a proper pucker, a genuine sour-candy sharpness sitting right at the front of your tongue, the sort of sensation that makes you notice you're vaping rather than just background-puffing without thinking. If you've ever eaten those sour blue belt sweets or sherbet-dusted bonbons, that's the reference point here, not a soft, rounded fruit vape.

Underneath the sourness sits the familiar blue raspberry sweetness, but on this one it's genuinely secondary, it's there to soften the sharpness rather than to lead. That ordering matters, because it's what separates a "sour" flavour that's just a gimmick from one that actually earns the name on every draw.

How it settles once you're a few draws in

The sourness doesn't stay at maximum intensity forever, which is a good thing, after the first few draws, it eases back and lets the sweet blue raspberry underneath come through more clearly, so you get a proper push-pull between the two rather than one flat sour note the whole way through. By the exhale, you're left with something closer to a standard blue raspberry, just with a tangy edge still clinging to the back of the throat.

This back-and-forth is honestly the most interesting part of the flavour, it's not static, and each pull gives you a slightly different balance depending on how deep and how long you draw. Quick, shallow puffs keep you mostly in sour territory; slower, fuller ones let more of the sweetness through instead.

Who's going to enjoy this

If you're someone who finds most fruit vapes a bit flat or samey, sour flavours tend to solve that problem because they give your mouth something more active to register rather than just sweetness sitting there. This one particularly suits vapers who liked sour sweets growing up and want that same "does my tongue actually hurt a bit" sensation in vape form. It's also a solid choice for anyone who vapes through long stretches of the day and finds sweeter liquids get boring fast, since the sourness keeps things feeling sharper for longer.

It's probably not the best pick if you're sensitive to sour or acidic flavours generally, or if you specifically want something mellow and easy for background vaping without really thinking about it much.

There's also a social side to a flavour this expressive, it's the sort of vape that gets a reaction if someone else tries a puff, precisely because the sour hit isn't subtle. If you enjoy that "wait, that's actually sour" moment when you hand a device to a mate, this is built for exactly that.

How it stacks up against other sour and blue raspberry vapes

Against a standard, non-sour Blue Raspberry, this is a noticeably more demanding flavour, less of a background sweet, more of a "sit up and notice it" flavour. Compared with sour apple or sour cherry liquids, the blue raspberry base keeps this one feeling more like a sweet shop than a fruit bowl, whereas apple and cherry sours often lean slightly more towards tart fruit than candy. And set against a plain raspberry lemonade style vape, Blue Sour Raspberry has none of the fizzy, drink-like quality, it's pure confectionery from start to finish.

• Keep a smoother, non-sour flavour on hand to switch to if the tang starts to feel like too much over a long session.
• Sour and menthol don't always mix well, if you like menthol, treat it as a separate-day flavour rather than a back-to-back rotation.
• A watermelon or strawberry sour makes a good rotation partner if you want to stay in sour-candy territory without repeating the exact same blue raspberry note.

A couple of things worth knowing

Sour flavourings can be more sensitive to coil wear than standard fruit liquids, as a coil ages, the sharp top notes are often the first thing to dull, so if the sourness starts fading faster than the sweetness, that's usually your sign a fresh coil or pod will bring it back. It's also worth pacing your draws rather than chain-vaping this one; because the sour hit is genuinely noticeable, slower use tends to keep it feeling like a treat rather than something your mouth simply goes numb to.

Blue Sour Raspberry: quick questions

How sour is "sour" here, is it too much?

It's a genuine sour hit rather than a token one, noticeable from the first draw, though it does mellow within a few seconds into the sweeter blue raspberry base underneath. Vapers who don't get on with sour sweets in general may find it a bit much.

Does the sourness fade the longer you use the same pod?

Sharp top notes like sour flavouring tend to soften slightly as a coil wears in, so the flavour often feels marginally less punchy towards the end of a pod's life compared with a brand new one.

Is this a good starter-kit flavour if I'm new to sour vapes?

It's a reasonable entry point since the sourness settles fairly quickly into a familiar blue raspberry sweetness, giving you the sour novelty without it dominating the entire draw from start to finish.
