“Most ‘sour apple’ vapes are lying to you. They’re sweet apple with green food coloring. You take a draw, get some generic candy sweetness, maybe a hint of something that could be apple or could be pear or could be melon — and there’s zero sour. Zero. The word ‘sour’ is just marketing.
RAZ Sour Apple Ice is different because it actually uses Malic Acid — the same compound that makes real Granny Smith apples sour. The first draw genuinely makes your cheeks pucker. It’s not ‘kind of tart.’ It’s the full mouth-watering, saliva-inducing, face-scrunching sour that you get from biting into a green apple with the skin still on. The ice finish comes second, cleaning up the acid and leaving your mouth feeling like you just drank cold apple juice.
I ran this across four devices. The VUE 50K‘s dual mesh coil does something interesting with sour flavors — it spreads the Malic Acid more evenly across the tongue, so instead of one sharp point of sourness on the tip, you get a wider, more even tart coating across the whole mouth. The DC25000 in Boost Mode turns up both the sour and the ice simultaneously — it’s the most aggressive version. The TN9000 keeps it balanced — sour up front, candy sweetness in the middle, ice on the exit. That’s the version most people start with.”
Sour Apple Ice is available on more platforms than most sour flavors. The hardware changes how the sour-sweet-ice balance plays out — here’s every option from the RAZ Vape store:
| Device | Sour | Ice | Mike’s Take |
|---|---|---|---|
| RAZ VUE 50K Kit | 8/10 | 7/10 | Dual mesh coil spreads the Malic Acid evenly across the whole tongue — wider sour coverage instead of one concentrated point. The candy sweetness comes through cleaner between the sour and ice stages. Most nuanced version of this flavor. |
| VUE 50K Pod | 8/10 | 7/10 | Same dual mesh experience. $19.99 refill for VUE base owners. A sour flavor that doesn’t degrade over 50,000 puffs — the acid stays consistent. |
| RAZ DC25000 | 9/10 | 7/10 | Boost Mode cranks both the sour AND the ice simultaneously — the most aggressive version. The higher wattage vaporizes more Malic Acid per draw, making each puff noticeably more tart. For people who want maximum pucker. |
| RAZ TN9000 | 8/10 | 6/10 | The balanced version most people start with. Sour hits first, candy sweetness fills the middle, ice cleans up the finish. All three stages are clearly separated — the best “introduction” device for this flavor. |
| RYL Classic 35K | 7/10 | 5/10 | Softer airflow takes the edge off the acid. The sour is present but gentler — more “tart apple cider” than “Granny Smith bite.” The easiest version to chain-vape without palate fatigue. |
💡 Mike’s Device Pick: For maximum sour → DC25000 Boost Mode. For the most balanced three-stage experience (sour → candy → ice) → TN9000. For even sour distribution that doesn’t burn out your tongue → VUE 50K.
Sour Apple Ice is one of the few RAZ flavors with three clearly distinct stages you can identify on every single draw. Most flavors blend together — this one keeps its layers separate:
-
🍏 Stage 1 — The Snap (Inhale):
Sharp, acidic zing that hits the tip and sides of your tongue first. This is the Malic Acid — the exact same compound that makes a real Granny Smith apple sour. It’s not “kind of tart.” Your cheeks will pucker. Your mouth will water. It’s the green apple with the skin on, specifically the first bite where you break through the waxy exterior into the tart flesh underneath. If you’ve ever eaten a sour gummy ring, it’s that initial face-scrunching moment before the sugar kicks in. -
🍬 Stage 2 — The Candy (Mid-draw):
The sourness peaks and then — right at the moment your brain says “too much” — a wave of candy sweetness arrives. Not cloying sugar, more like a green apple Jolly Rancher dissolving on your tongue. This middle layer is what separates Sour Apple Ice from pure sour flavors. It gives your palate a break, turns the acid into something enjoyable instead of punishing, and creates that “sour candy” profile that makes you reach for the next draw immediately. -
❄️ Stage 3 — The Rinse (Exhale):
Moderate menthol on the exhale that serves two functions: first, it clears the acid residue off your palate so the sourness doesn’t accumulate and become unpleasant over time. Second, it adds the “cold apple juice” sensation — like you just drank a glass of apple juice straight from the fridge. The ice is intentionally moderate at 6/10 — strong enough to clean up, not so strong that it overpowers the sour-candy core.

If you search “RAZ sour flavors,” these two come up every time. They’re both sour, they’re both popular, and they appeal to completely different people. Here’s the real breakdown:
| Attribute | Sour Apple Ice | Night Crawler |
|---|---|---|
| Sour Type | “Focused” sour — one fruit, sharp acid, clean finish | “Complex” sour — mixed fruit gummy worms, layered and dense |
| Primary Flavor | Granny Smith green apple — unmistakable, specific, clean | Mixed berry + citrus + mystery fruit — you can’t name them all |
| Sweetness | 5/10 — candy layer is restrained, sour dominates | 7/10 — sweeter and more candy-like overall |
| Ice Level | 6/10 — moderate menthol clean-up on exhale | 3/10 — barely any ice, the fruit stays warm and dense |
| Best For | People who want a specific sour fruit with a crisp, clean finish | People who want a complex sour candy experience with depth |
| Think Of It As… | A sour Jolly Rancher — sharp, single-note, clean | A bag of sour gummy worms — dense, layered, mysterious |
The shortcut: If you know you want green apple and you want it sour with a cold finish → Sour Apple Ice. If you want a candy bag mystery with multiple sour fruit layers and no ice → Night Crawler. If you can’t decide, buy both — they’re different enough that having both in rotation makes sense.
Sour flavors respond to wattage changes more dramatically than most other profiles. Higher wattage vaporizes more Malic Acid per draw, which directly increases the sourness — it’s not subtle:
| Attribute | Normal Mode (12W) | Boost Mode (24W) |
|---|---|---|
| Sour Intensity | Noticeable pucker — clearly sour but manageable for extended sessions | Aggressive face-scrunch — each draw delivers a concentrated acid hit |
| Candy Middle | Clearly present — the sweet layer gets enough space to develop fully | Gets compressed — the sour and ice nearly swallow the candy stage |
| Ice Finish | Gentle rinse — cleans the acid residue without drawing attention | Amplified — the menthol pushes harder, creating a “frozen sour apple” effect |
| Coil Impact | Standard wear — Malic Acid is naturally coil-friendly at lower temps | Slightly faster coil darkening — higher temps accelerate acid residue buildup |
| Best For | All-day sour candy enjoyment, work sessions, casual use | Short “sour blast” sessions — post-meal palate reset, waking up, showing off |
💡 Pro tip: On the VUE 50K, Boost Mode amplifies the sour more evenly across the tongue because of the dual mesh coil — you get a wider acid coating instead of a sharper throat-focused hit. On the DC25000, Boost Mode concentrates the sour more on the tip of the tongue. Both are intense — choose based on whether you want “wide sour” or “sharp sour.”
“Sour Apple” is one of the most common vape flavors across every brand. The problem is that most of them aren’t actually sour — they’re sweet apple with a green color. I tested four side by side:
| Brand | Profile | Pros & Cons |
|---|---|---|
| RAZ Sour Apple Ice | Real Malic Acid sour + candy middle + menthol rinse. Three distinct stages. Genuine pucker factor. |
✔ Actually sour — the Malic Acid creates genuine tartness, not just “tangy” ✔ Three-stage flavor architecture (sour → candy → ice) keeps every draw interesting ✔ Available on 5 devices including VUE 50K dual mesh ✔ Coil-friendly formula despite the acid content ✘ The ice finish may be too mild for hardcore menthol fans (6/10) |
| Geek Bar Pulse (Sour Apple) | Sweet green candy + minimal tartness. More “apple candy” than “sour apple.” |
✔ Easy to vape — inoffensive, sweet, approachable ✘ Not actually sour — maybe 3/10 tartness at best ✘ Tastes more like green Skittles than green apple |
| Elf Bar BC5000 (Sour Apple) | Mild green apple + slight pucker. Barely qualifies as “sour.” |
✔ Clean flavor — no chemical aftertaste ✘ So mild it could be pear or melon — the apple identity is vague ✘ Sourness fades completely after 300-400 puffs |
| Funky Lands Vi15000 (Sour Apple) | Synthetic green apple + harsh acidic bite. Aggressive but artificial. |
✔ Genuinely sour — higher acid content than most competitors ✘ The acid tastes chemical rather than fruity — artificial sourness ✘ Destroys coils — noticeable burnt taste develops within days ✘ No ice finish, so the acid just sits on your palate with no cleanup |
Verdict: RAZ wins on authenticity. The Malic Acid creates a sourness that actually tastes like green apple, not generic citric acid. Geek Bar and Elf Bar aren’t sour — they’re sweet apple candies marketed as “sour.” Funky Lands is legitimately sour but the acid tastes artificial and kills coils. RAZ is the only one that delivers genuine sour, coil-friendly formula, and an ice finish that cleans up the acid so it doesn’t accumulate.
RAZ has five flavors in the sour/apple territory. They range from single-note sour to complex candy mixes:
| Flavor | Primary Notes | Sour | Sweet | Best For |
|---|---|---|---|---|
| Sour Apple Ice ★ | Green Apple + Acid + Menthol | 8/10 | 5/10 | Single-fruit sour with clean ice finish — the “Jolly Rancher” |
| Sour Apple Watermelon | Green Apple + Watermelon + Tart | 6/10 | 7/10 | Watermelon softens the acid — sweeter, juicier, easier to chain-vape |
| Night Crawler | Mixed Sour Gummy Worms | 7/10 | 7/10 | Complex candy sour — multiple mystery fruits, dense and layered |
| Bangin’ Sour Berries | Mixed Sour Berries | 7/10 | 6/10 | Berry-focused sour — wider fruit spectrum, tart without being sharp |
| Cherry Strapple | Sweet Cherry + Apple | 2/10 | 8/10 | Apple flavor WITHOUT the sour — sweet, fruity, zero tartness |
Quick guide: Want maximum sour? → Sour Apple Ice. Want sour with more sweetness? → Sour Apple Watermelon. Want sour candy complexity? → Night Crawler. Want apple but zero sour? → Cherry Strapple.
After a rich, heavy meal — steak, pasta, fried food — your palate is coated in fat and salt and your taste buds are muted. Sour Apple Ice on the DC25000 Boost Mode is the palate equivalent of a power wash. The Malic Acid cuts through the fat coating on your tongue, the candy middle tells your brain “dessert is served,” and the ice finish rinses everything clean. Three draws and your mouth feels completely reset. Multiple customers have told us this is specifically their “after dinner” flavor.
If you used to eat sour gummy rings, sour belts, or Warheads, Sour Apple Ice on the TN9000 hits the exact same reward center in your brain — the initial pucker, the candy payoff, the satisfaction. Except it’s zero calories, zero sugar, and your dentist won’t yell at you. The three-stage architecture (sour → candy → ice) mimics the experience of eating sour candy so accurately that multiple customers have reported it replaced their actual candy habit.
If your usual rotation is all sweet — Razzle Dazzle, Strawberry Shortcake, Graham Twist — your palate adapts to sweetness and everything starts tasting the same. Swapping to Sour Apple Ice for an hour recalibrates your taste buds back to baseline because the acid triggers completely different receptors. When you switch back to your sweet flavors, they’ll taste vivid again. Think of Sour Apple Ice as a “palate sharpener” — it makes your other flavors taste better by contrast.
Sour Apple Ice in Normal Mode on the VUE 50K or RYL 35K is the vape equivalent of cold apple juice on a hot afternoon. The sour is present but not punishing at lower wattage, the candy sweetness gives you that “treat” feeling, and the ice finish is just cold enough to be refreshing. It’s lighter than the DC25000 Boost experience — something you can sip on casually while sitting outside, reading, or driving with the windows down.

“I judge sour flavors by one test: does the first draw make your face move involuntarily? Sour Apple Ice passes. Most ‘sour’ vapes don’t. The Malic Acid is real, the three-stage architecture works, and the ice finish prevents acid fatigue. 30+ sour vapes tested — this is one of three that actually deserve the word ‘sour’ on the label.”
