Flum Flavors Ranked — Top 11 by Score
#1 · Mango Ice — 71/100
Lush, nectar-sweet mango drenched in tropical sweetness opens the draw — pure Alphonso nectar with a buttery mid-palate that coats the tongue. The ice arrives late on the exhale, a cool breeze rather than a frost blast, sharpening the mango's edges without dulling the sweetness. Aftertaste is a golden trail of tropical sugar, persistent and warm.
Edge: Highest overall score in the Flum lineup. The mango-to-ice ratio is calibrated perfectly — enough cooling to refresh but never enough to bury the fruit.
#2 · Watermelon Ice — 70/100
Sugar-forward watermelon candy floods the first inhale — closer to a Jolly Rancher than a fresh slice. The mid-draw leans into candy-store sweetness with a faint rind note sneaking through. Exhale delivers the strongest ice hit in the Flum lineup at 70, a clean frost that lifts the melon. Aftertaste is short, a sweet pink echo that fades clean.
Edge: Tied for second-highest Flum score. The cooling actually registers here — a rarity for this brand.
#3 · Grape Ice — 70/100
Maximum grape sweetness — this is grape candy taken to eleven. The Concord grape hits bold and purple on the inhale, pure Fanta energy with a crystalline sugar shell. Mid-draw stays sweet and one-dimensional but the intensity is the point. Exhale carries a moderate frost layer that sharpens the candy edges. Aftertaste drops off fast — grape doesn't linger.
Edge: Flum cranks grape past candy into sugar-bomb territory. Not subtle, but committed.
#4 · Peach Ice — 70/100
Flum turns peach into a sugar-drenched candy experience — velvety soft on the inhale with a stone-fruit musk in the mid-draw that adds depth. The sweetness dominates, pushing past natural peach into candied territory. Exhale cooling is restrained, a gentle chill rather than a freeze. Aftertaste carries an aromatic peach-fuzz note that's actually pleasant.
Edge: The most aromatic of Flum's ice variants. You smell this one before you taste it.
#5 · Blueberry Ice — 69/100
Flum's blueberry is a sugar bomb — heavy sweetness that skews candy rather than wild berry. The dark, inky fruit note on the inhale gives way to a powdered-sugar mid-draw that softens any tartness. The ice is background noise at 67, present but not assertive. Aftertaste carries a faint tannic quality, like grape skin without the bitterness.
Edge: More blueberry muffin batter than fresh blueberry. Sweet-tooth approved.
#6 · Gummy Bear — 69/100
Haribo Gold-Bear in vapor form. The sweetness is eye-watering — 86 on our scale, the highest single reading in the Flum catalog. The first inhale is pure candy-shop immersion, unmistakable gummy-bear fruitiness without any specific fruit dominating. Mid-draw reveals layers: a gelatin note, a citric-acid whisper, a sugary chew. Zero cooling. The aftertaste is long at 70, a sticky-sweet candy memory that hangs on the palate.
Edge: The sweetest Flum flavor, period. Also the highest Authenticity score at 76 — Flum nailed the gummy-bear target perfectly.
#7 · Lemon Ice — 69/100
More lemon drop candy than fresh citrus — Flum's sweetness filter turns even lemon into a sugar delivery device. The initial inhale has a zesty pucker that gives way to candy-lemon sweetness in the mid-draw. Exhale cooling ties with Watermelon Ice at 70 for strongest in the lineup. Aftertaste is short and crisp — lemon doesn't overstay.
Edge: The citric acid zing cuts through Flum's typical sweetness more than other flavors, creating better balance.
#8 · Sour Gummy — 67/100
Flum plus sour candy equals maximum sweetness with a tart edge. The sour hits hard upfront — a citric-acid punch that grabs attention — then the sweetness steamrolls it by mid-draw. This is a sour-candy-belt profile, the kind where sugar coating outweighs the sour center. Zero cooling. The aftertaste lingers as a sweet-sour echo, sticky and persistent.
Edge: The sour note provides the only real flavor tension in Flum's portfolio. Second-highest sweetness at 83.
#9 · Vanilla Ice Cream — 66/100
Flum's vanilla drips with sweetness — vanilla ice cream sundae with extra whipped cream and caramel. The inhale is silky, egg-custard rich, a warm bourbon-vanilla base. Mid-draw coats the tongue in butterscotch warmth, thick and indulgent. Zero cooling — this is a warm dessert, served as intended. Aftertaste is the longest in the Flum lineup, a golden vanilla trail that persists 15+ seconds.
Edge: The most complex Flum flavor from a layering perspective. Third-highest sweetness at 84, but the custard depth makes it feel less one-note.
#10 · Strawberry Banana — 65/100
Flum cranks the sweetness to candy-shop levels on this smoothie classic. The strawberry leads — intense, more Starburst than real berry — with a ripe banana following in the mid-draw, soft and musky. The blend creates a third flavor, a creamy fruitiness that neither component has alone. Zero cooling. Aftertaste is warm and fruity, like a tropical breakfast lingering into afternoon.
Edge: The banana persistence on the exhale creates a flavor shift rare in Flum's lineup. Most Flum flavors are static; this one develops.
#11 · Cool Mint — 64/100
The outlier. Flum adds a hint of sweetness to their mint — unusual but not unwelcome, a candy-mint quality. The peppermint is sharp and clean on the inhale, and the cooling actually delivers at 76 — the only Flum flavor that takes ice seriously. The exhale is arctic air, mentholated and bracing. Aftertaste carries a spearmint whisper underneath. The lowest sweetness in the entire Flum lineup at 38.
Edge: Proves Flum can do cooling when they want to. The highest throat hit (62) in the lineup — this one bites back.

Flum Flavor Spectrum
Of Flum's 111 flavors:
- 38% Fruit-Ice — Flum's largest category, but the "ice" is always secondary to the sugar. Expect candy fruit with a cool afterthought.
- 22% Pure Fruit & Tropical — Tropical blends, berry combos, and stone fruits. Heavy on mango, peach, and watermelon variations.
- 15% Candy & Sour — Gummy bears, sour belts, ranchers. Where Flum's sugar-maximalist philosophy was born.
- 12% Beverage & Mixed — Lemonades, smoothies, root soda. The UT Bar Pro 50K dual-flavor system creates unique beverage pairings.
- 8% Dessert — Vanilla ice cream, gelato, cream blends. Rich and indulgent with long aftertastes.
- 3% Menthol/Mint — Cool Mint and spearmint variants. The smallest category — Flum clearly prefers sweetness over chill.
- 2% Tobacco — Tobacco and Tobacco Cream. Present but minimal.
Flum's Flavor DNA
Flum's philosophy is sugar-first, everything-else-second. The brand averages 77 on Sweetness — seven points above the cross-brand mean of 70 and the highest of any brand we've tested. Even flavors that should lean tart (Lemon Ice, Grape Ice) get the Flum sugar treatment, pushing past natural flavor into candy territory.
Where Geek Bar invests in authenticity (avg 81) and RAZ plays the candy-sour balance, Flum commits fully to the sweetness dial. The trade-off is cooling: at an average of 48 on the Cooling dimension, Flum's ice flavors feel like a cool breeze rather than an arctic blast. Cool Mint at 76 is the only exception — every other ice variant sits between 66-70.
The UT Bar Pro 50K deserves special mention for its dual-flavor architecture. Pairing two flavors per pod creates combinations impossible in single-chamber devices: Passionfruit / Mango, Cola Ice / Cherry, Root Soda / Vanilla. This isn't a gimmick — it's a genuine differentiator that no other brand in our catalog offers at this scale.
Aroma intensity is Flum's second strength at 78, trailing only sweetness. Every Flum puff fills the room. The combination of high sweetness and high aroma creates what our panel calls the "candy store effect" — before you taste it, you smell it, and the experience begins pre-inhale.

Full Tasting Profiles — Every Flum Flavor Reviewed
🍇 Fruit & Tropical
Fruit is Flum's playground, and the brand treats every fruit like a candy factory input. Expect sugar amplification across the board — Flum's fruit flavors average 80+ on sweetness, meaning even "natural" fruits like peach and mango read more like their candy counterparts.
Mango Ice
Overall: 71/100

Mid-draw: Buttery mango flesh develops, coating the tongue in a smoothie-like richness. A peachy crossover note adds depth.
Exhale: The ice arrives late, a cool breeze that sharpens the mango's sweet edges. Not aggressive — just enough to refresh.
Aftertaste: A golden trail of tropical sugar lingers 10-12 seconds. Warm, aromatic, inviting the next draw.
Sweet 81 · Cool 68 · Auth 72 · After 66 · Throat 57 · Aroma 80
Watermelon Ice
Overall: 70/100

Mid-draw: The sugar intensifies with a faint rind note sneaking in, adding a green, vegetal edge that grounds the candy.
Exhale: Frost arrives clean and crisp at 70 — Flum's strongest ice delivery alongside Lemon Ice. The cold lifts the melon.

Sweet 80 · Cool 70 · Auth 69 · After 65 · Throat 60 · Aroma 78
Grape Ice
Overall: 70/100
Inhale: Concord grape crashes in bold and purple — grape Fanta energy with a crystalline sugar shell. Unmistakably candy.
Mid-draw: The sweetness holds steady at 80, one-dimensional but intensely committed. No skin tartness, no wine notes, just candy grape.
Exhale: Moderate frost at 68 sharpens the candy edges. The cooling adds structure to what would otherwise be flat sweetness.

Sweet 80 · Cool 68 · Auth 69 · After 65 · Throat 57 · Aroma 77
Peach Ice
Overall: 70/100
Inhale: Velvety peach sweetness opens soft — stone-fruit sugar with a candied glaze that pushes past natural.
Mid-draw: A fragrant, almost floral depth emerges. The stone-fruit musk adds complexity the sweetness alone can't provide.
Exhale: Restrained cooling at 66 — a gentle chill rather than a freeze. The peach fragrance carries through the cold.
Aftertaste: Aromatic peach-fuzz note that you smell as much as taste. Pleasant and persistent.
Sweet 80 · Cool 66 · Auth 70 · After 65 · Throat 58 · Aroma 78
Blueberry Ice
Overall: 69/100
Inhale: Dark, inky blueberry arrives heavy with sugar — more blueberry muffin batter than wild berry picking.
Mid-draw: Powdered-sugar sweetness coats the mid-palate, softening any tartness the blueberry tries to assert.
Exhale: Background ice at 67, present but not assertive. The frost is a subtle accent, not a statement.
Aftertaste: A faint tannic quality, like grape skin without bitterness. Unique among Flum's fruit-ice lineup.
Sweet 79 · Cool 67 · Auth 68 · After 64 · Throat 57 · Aroma 77
Lemon Ice
Overall: 69/100
Inhale: Lemon drop candy — a zesty pucker filtered through Flum's sweetness amplifier. The citric acid zing is present but tamed.
Mid-draw: Candy-lemon sweetness takes over, crystalline and sharp. Less raw citrus, more lemon Starburst.
Exhale: The strongest ice in the Flum stable alongside Watermelon Ice at 70. Clean and astringent, resetting the palate.
Aftertaste: Short and crisp — lemon doesn't linger, and the cooling evaporates clean.
Sweet 78 · Cool 70 · Auth 68 · After 64 · Throat 58 · Aroma 76
Strawberry Banana
Overall: 65/100
Inhale: Strawberry leads intense and sweet — more Starburst than real berry, with Flum's signature sugar amplification.
Mid-draw: Ripe banana follows soft and musky, creating a creamy third flavor that neither fruit achieves alone.
Exhale: Zero cooling. The banana reveals itself more on the exhale than inhale — a warm, tropical shift.
Aftertaste: Warm and fruity, like a tropical breakfast lingering past noon. One of the longer Flum finishes.
Sweet 82 · Cool 10 · Auth 70 · After 67 · Throat 58 · Aroma 79
Aloe Grape
Cool aloe vera base meets Concord grape sweetness. The aloe provides a mild herbal backbone — slightly bitter, slightly green — that keeps the grape from going full candy. One of the more balanced Flum profiles, though sweetness still leads.
Aloe Watermelon
The aloe adds a vegetal coolness to watermelon that mimics ice without the menthol. Softer than Watermelon Ice, with an herbal edge that gives the melon room to breathe. A good choice for vapers who want watermelon without the typical sugar overload.
Thai Mango
A tangier, more fibrous mango profile than Mango Ice — closer to green mango with chili salt minus the salt. The tropical sweetness is there but tempered with a tart bite that adds dimension.
Thai Mango Icy
Thai mango's tartness meets a clean menthol finish. More complex than standard Mango Ice — the green-mango character adds a sour backbone the ripe mango variant lacks.
Passion Kiwi
Tart passionfruit leads with a citric punch, then fuzzy kiwi rounds out the mid-draw. Less sweet than most Flum fruits, with a tangy acidity that makes it feel genuinely refreshing.
Passion Kiwi Pineapple
Triple tropical stack — passionfruit tartness, kiwi fuzz, and pineapple brightness layered together. The pineapple adds an acidic bite that cuts through Flum's natural sweetness. One of the more complex fruit profiles in the lineup.
Passionfruit / Mango
Tart passionfruit on one side, nectar-sweet mango on the other. The dual system creates a sweet-sour pendulum effect that single-chamber devices can't replicate.
Straw Mango
Strawberry and mango merged into a single tropical-berry blend. The strawberry provides tartness while mango brings warmth and body. A smoothie-shop classic rendered in Flum's sugar-forward style.
Strawberry Blast
Pure strawberry turned up to maximum intensity. Candy-berry sweetness with zero subtlety — this is strawberry as a flavor weapon. Jammy mid-notes with a tart edge on the exhale.
Straw Guava
Strawberry's familiar sweetness paired with guava's musky, tropical depth. The guava adds an aromatic complexity — fragrant and slightly funky — that elevates the strawberry beyond basic candy.
Strawmelon
Strawberry-watermelon fusion — two of Flum's sweetest fruits combined. The strawberry provides tartness structure, watermelon adds a watery juiciness. Sweet but balanced by the fruit interplay.
Strawmelon Peach
Triple-fruit complexity: strawberry tartness, watermelon juice, peach velvet. The peach softens the blend with its stone-fruit musk, creating a smoother finish than Strawmelon alone.
Strawberry Watermelon
Similar profile to Strawmelon but in the dual-chamber 50K format. The larger device allows more vapor production, which amplifies the watermelon's juicy quality and extends the strawberry's tart finish.
White Peach / Raspberry
Delicate white peach on one side, tart raspberry on the other. The dual format preserves each fruit's identity — the peach stays soft and floral, the raspberry stays sharp and sour.
White Peach / Lemon Head
White peach's soft sweetness paired with sour lemon-head candy. The contrast is extreme — velvety fruit versus citric acid bomb. A dual-flavor that actually benefits from the two-chamber separation.
Peach Mango Watermelon
Triple tropical stack — peach velvet, mango nectar, watermelon juice blended into a fruit smoothie. Each fruit takes its turn: peach opens, mango fills the middle, watermelon finishes with a watery sweetness.
Green Apple / Fuji Apple
Granny Smith tartness versus Fuji sweetness — the dual format turns two apples into a sweet-sour conversation. The green apple provides crunch and acid, the Fuji adds honey and warmth.
Sour Apple
Granny Smith tartness with Flum's signature sweetness layered on top. Less sour than the name suggests — Flum can't help itself from adding sugar. Still, the apple's natural crispness cuts through.
Sour Apple Icy
Sour Apple plus a menthol finish. The ice sharpens the tartness rather than masking it — one of the better-balanced ice profiles in Flum's catalog.
Lime Splash
Tart lime with a fizzy, effervescent quality — like a lime soda rather than fresh lime juice. The citric acid provides a palate-cleansing sharpness unusual in Flum's sweet-leaning lineup.
Watermelon Peach Lime
Triple blend — watermelon's watery sweetness, peach's velvety depth, lime's tart edge. The lime is the surprise player, adding an acid backbone that prevents the blend from going flat.
Watermelon Blueberry
Pink watermelon meets dark blueberry — two fruits that shouldn't work together but do. The watermelon's light, watery sweetness tempers the blueberry's inky depth.
Watermelon Sour Peach
Watermelon juice meets sour peach rings — the sour element adds a tart punch that Flum's standard watermelon flavors lack. The peach brings aromatic depth to the watermelon's clean sweetness.
Raspberry Apple Blackberry
Triple berry-fruit blend — raspberry tartness, apple crispness, blackberry depth. Complex and layered, with each fruit asserting itself at different stages of the draw.
Raspberry Grape / Guava
Berry tartness paired with tropical guava musk. The dual format keeps the raspberry-grape's sharp profile separate from guava's aromatic warmth.
Mexican Mango
Mango with a chili-lime edge — inspired by Mexican street-style mango with Tajín. The spice note is subtle but present, adding warmth to the sweet mango base.
Double Green Pop
Double-strength green apple popsicle — frozen, tart, and intensely green. Brighter than standard Sour Apple with a frozen-treat quality that mimics an actual popsicle.
Red Pop
Red popsicle flavor — that generic cherry-strawberry-raspberry blend that every frozen pop labeled "red" somehow tastes like. Nostalgic and impossible to pin to a single fruit.
Grape Pop Icy
Frozen grape popsicle — Concord grape sweetness encased in a frost shell. The "pop" frozen-treat format adds a watery iciness that standard Grape Ice lacks.
Mt. Rainier
A mystery mountain-inspired blend — alpine berries with a crisp, cold finish. The name suggests frost and elevation, and the flavor delivers: clean berry sweetness with a sharp, mountain-air coolness.
Wild Berry Drop
Mixed berry hard candy — a berry blend that doesn't commit to any single fruit but delivers concentrated berry sweetness. Fruity, round, and predictably sweet.
Cherry Strawberry Gummy
Cherry-strawberry gummy candy — the cherry adds a dark, slightly tart note to strawberry's bright sweetness. Chewy candy quality with Flum's characteristic sugar saturation.
Lemon Drop
Lemon hard candy — crystalline, sharp, and sweet with a citric acid zing. Purer lemon delivery than Lemon Ice, without the cooling distraction.
Sunshine Cherry
Bright, sun-sweet cherry with a warm, golden quality — less dark-cherry tartness, more maraschino sweetness. A happy, uncomplicated cherry profile.
Ruby Green
Ruby-sweet berry blend with green apple tartness. The "ruby" suggests pomegranate or cranberry undertones, and the green apple provides crunch and acid balance.
Ruby Yellow
Ruby berry sweetness meets yellow fruit brightness — likely citrus or pineapple undertones. A warm, golden-sweet profile with a tart edge.
❄️ Ice & Mint
Flum's smallest category by far — only 3% of the lineup. The brand clearly prioritizes sweetness over chill. When Flum does ice, it's always a supporting character, never the lead. Cool Mint is the exception: the only flavor where cooling takes center stage.
Cool Mint
Overall: 64/100
Inhale: Sharp peppermint with an unexpected hint of sweetness — Flum can't resist adding sugar even to mint.
Mid-draw: The cooling builds to 76, the highest in the Flum catalog. Mentholated and bracing, like unwrapping a candy cane in winter.
Exhale: Arctic air — you feel it in your sinuses. A spearmint whisper underneath the dominant peppermint adds herbal depth.
Aftertaste: Residual chill persists 10-15 seconds. The sweetness makes the aftertaste warmer than expected.
Sweet 38 · Cool 76 · Auth 71 · After 64 · Throat 62 · Aroma 67
Miami Mint
Spearmint-forward with a mojito quality — greener and softer than Cool Mint. The herbal note is stronger, like fresh mint leaves muddled with a touch of sugar. More "ocean breeze" than "blizzard." Flum's all-day mint option.
Spearmint Watermelon
Fresh spearmint layered over watermelon sweetness — an unconventional pairing that works better than expected. The mint provides a green, herbal framework that keeps the watermelon from going full candy.
Blue Razz Icy
Electric blue candy sweetness with a sour tang and menthol finish. The "razz" is proudly artificial — no actual raspberry tastes like this. The ice sharpens the candy into a frozen snow-cone profile.
Blue Razz / Lemonade
Blue raspberry candy on one side, tart lemonade on the other. The dual format creates a sour-sweet oscillation — candy bomb versus citrus cleanser. One of the better dual-flavor pairings.
BlueRazz Ice / Triple Berry
Blue razz with ice paired against a mixed triple-berry blend. The blue razz provides artificial candy energy while the triple berry adds a more natural, rounded berry profile.
Sour Fab / Citrus Ice
Sour candy meets iced citrus — a tart-on-tart dual that puckers from both sides. The citrus ice provides a clean menthol-lemon exit after the sour candy assault.
Frozen Watermelon
Frozen watermelon popsicle — the "frozen" treatment adds more cooling than standard Watermelon Icy. Think frozen watermelon chunks rather than watermelon juice on ice.
🍬 Candy & Sour
Flum's spiritual home. Where the brand's sugar-maximalist philosophy was born and where it shines brightest. Every candy flavor delivers exactly what the name promises: pure, unapologetic sweetness.
Gummy Bear
Overall: 69/100
Inhale: Haribo Gold-Bear in vapor form — pure candy-shop immersion with no single fruit dominating. The sweetness is immediate and overwhelming at 86.
Mid-draw: Layers emerge: a gelatin note, a citric-acid whisper, a sugary chew. More complex than the initial sugar rush suggests.
Exhale: Zero cooling. The sweetness carries through uninterrupted — warm, sticky, enveloping.
Aftertaste: Long at 70, the highest in the Flum candy lineup. A sticky-sweet candy memory that hangs on the palate.
Sweet 86 · Cool 12 · Auth 76 · After 70 · Throat 54 · Aroma 82
Sour Gummy
Overall: 67/100
Inhale: Citric acid punch grabs attention — a sour-candy-belt opening with genuine tartness before the sugar rolls in.
Mid-draw: The sweetness steamrolls the sour by mid-draw. At 83, this is a sour candy where sugar coating outweighs the sour center.
Exhale: Zero cooling. The sour-sweet tension resolves into pure sweetness on the exhale. The sour's last stand.
Aftertaste: A sweet-sour echo that's sticky and persistent. The citric acid ghost lingers after the sugar settles.
Sweet 83 · Cool 10 · Auth 74 · After 68 · Throat 56 · Aroma 78
White Gummy
White gummy bear — the pineapple-citrus variant of the gummy family. Slightly less sweet than standard Gummy Bear, with a tropical brightness that gives it more dimension.
White Gummy / Cherry
White gummy's pineapple brightness paired with cherry's dark tartness. The dual format creates a fruity candy buffet — lighter tropical on one side, deeper berry-cherry on the other.
Sour Burst
Concentrated sour candy explosion — imagine a Sour Patch Kid compressed into a single puff. The citric acid hits hard and the sweetness chases it aggressively.
Aloe Watermelon / Sour Sweet
Cool aloe watermelon on one side, generic sour-sweet candy on the other. The aloe provides an herbal contrast to the candy — a dual that covers both refreshing and indulgent.
Blue Rancher / Lemonade
Blue Jolly Rancher candy paired with tart lemonade. The rancher side is pure candy sweetness — artificial, electric blue, unapologetically fake. The lemonade provides acid balance.
Tropocal Rainbow Blast
Skittles-adjacent tropical rainbow — a fruit candy medley that hits every color of the candy spectrum. Generic but fun, sweet and vibrant.
Strawberry Swirl
Strawberry candy with a swirl of cream — like a strawberry cream hard candy unwrapped. The cream adds richness without pushing into full dessert territory.
Pink Lemonade / Mixberry
Tart pink lemonade paired with mixed berry sweetness. The lemonade provides acid structure while the berry blend adds fruity depth. A well-matched dual combination.
🍰 Dessert & Cream
Flum's dessert category runs warm, rich, and intensely sweet. Zero cooling across the board — these are meant to be the flavor equivalent of sitting down to actual dessert.
Vanilla Ice Cream
Overall: 66/100
Inhale: Silky egg-custard richness opens the draw — bourbon-vanilla, warm and amber, with a butterscotch undertone.
Mid-draw: Thick and coating, the vanilla develops into a full ice-cream-sundae experience with extra whipped cream.
Exhale: Zero cooling. Pure warm indulgence — the butterscotch deepens, the vanilla holds steady.
Aftertaste: The longest in the Flum lineup — a golden vanilla trail persists 15+ seconds. Room-filling aroma.
Sweet 84 · Cool 8 · Auth 70 · After 68 · Throat 55 · Aroma 80
Strawnana / Gelato
Strawberry-banana smoothie paired with Italian gelato cream. The dual format separates the fruit from the cream — inhale the fruity side, then switch to creamy gelato. Dessert in dual-chamber form.
Root Soda / Vanilla
Root beer float in dual format — fizzy, spiced root soda on one side, smooth vanilla cream on the other. The root soda's sassafras-anise spice paired with vanilla's warm sweetness mimics the classic American float.
Tobacco Cream
Virginia tobacco mellowed with a cream layer — the tobacco provides a dry, hay-like backbone while the cream adds sweetness and smoothness. For tobacco fans who want a dessert-tobacco hybrid.
Banana Smoothy / Strawberry
Banana smoothie blended smooth on one side, pure strawberry on the other. The banana brings ripe, musky sweetness while the strawberry provides a tart-sweet counterpoint.
🥤 Beverage
Flum's beverage category benefits enormously from the dual-flavor UT Bar Pro 50K, which can pair beverage bases with complementary flavors in a way single-chamber devices can't replicate.
Cola Ice / Cherry
Cherry cola in dual format — spiced cola with a caramel backbone on one side, dark cherry sweetness on the other. The cherry-cola combination is a classic, and the dual system keeps each flavor crisp.
Slushy / Lemon
Icy slushy base paired with tart lemon. The slushy adds a frozen, watery texture quality while the lemon provides citric acid brightness. A frozen lemonade stand in dual-chamber form.
Watermelon / B-Pop
Watermelon on one side, B-Pop candy on the other. The "B-Pop" brings a generic berry-candy sweetness that pairs with watermelon's watery, clean profile.
Watermelon Icy / Slushy
Watermelon ice paired with an icy slushy base — double-frozen watermelon from two angles. The slushy adds a watery texture that the standard ice variant lacks.
Mango / Strawberry
Tropical mango nectar on one side, tart strawberry on the other. Two of Flum's strongest individual fruit profiles combined in dual format — a tropical-berry smoothie that you can experience from either chamber.
Strawberry / Watermelon Icy
Warm strawberry sweetness paired with iced watermelon. The temperature contrast — warm fruit versus cold fruit — is the real draw here.
🌸 Lifestyle & Mystery Blends (Mello 20K Signature Series)
The Mello 20K features a series of flavors named after moods, places, and experiences rather than specific fruits. These are Flum's most creative offerings — abstract names that force you to discover the flavor rather than predict it.
Blossom
Floral-forward with cherry blossom and light berry undertones. Delicate and perfume-like — the most feminine flavor in Flum's catalog. Low sweetness for a Flum profile, with an aromatic quality that lingers.
Bluebell
Blueberry meets floral — a blueberry profile with a violet-like, slightly perfumed top note. Soft, rounded, and unexpectedly sophisticated for a Flum flavor.
Crush
Fruit crush soda energy — bright, fizzy, and generically fruity. Likely orange or grape crush-adjacent, with that carbonated-candy quality.
Daisy Jazzy
A playful floral-fruit blend — daisy-like lightness with a jazzy fruit medley underneath. Abstract and whimsical, with a sweetness that stays restrained by Flum standards.
Fabulous
A mystery candy blend — sweet, fruity, and unapologetically flashy. The name matches the profile: bold, colorful, and committed to fun over subtlety.
Heartbeat
Sweet berry-candy with a rhythmic sweetness that builds and pulses. Likely a strawberry-raspberry heart candy profile — red, sweet, and romantic.
Midnight Barcelona
Dark, sophisticated blend — think dark grape or sangria-adjacent with a warm spice undertone. The most adult-coded flavor in Flum's Mello lineup.
Milano Adore
Italian-inspired sweetness — likely a hazelnut-cream or amaretto-adjacent profile with European dessert sophistication. Warm, nutty, and refined.
Rome
Another Italian-coded blend — possibly a citrus-herb profile inspired by Italian limoncello or blood orange. Warm, golden, and Mediterranean.
Summer Delux
Multi-fruit summer cocktail — a blend of warm-weather fruits that reads like a fruit salad or tropical punch. Bright, sweet, and seasonal.
Sapphire
Blue-coded mystery flavor — likely blue razz or mixed berry with a jewel-like clarity. Cool-toned sweetness that feels polished and precise.
Velvet
Red velvet cake — cocoa powder meets cream cheese frosting with a whisper of vanilla. The texture is smooth and coating, living up to the "velvet" name.
Vienna Bliss
Austrian pastry-inspired — think Sachertorte: chocolate-apricot with a cream layer. Warm, sophisticated, and dessert-forward.
🚬 Tobacco
Flum's smallest category — only two tobacco flavors across the lineup. Even here, Flum adds sweetness: Tobacco Cream softens the leaf with dairy, and the standard tobacco carries a hint of honey.
Tobacco
Virginia-forward with a mellow, golden, hay-like sweetness. Surprisingly authentic for a brand that leans candy on everything else — the tobacco character comes through with a dry, warm finish. The throat hit is moderate, satisfying for ex-smokers without punishing.
Tobacco / Gold Tobacco
Standard Virginia tobacco on one side, honey-sweetened "gold" tobacco on the other. The dual format creates a straight-to-sweet tobacco transition that ex-smokers transitioning to vaping might appreciate.
💧 Clear / Neutral
Clear
Unflavored nicotine delivery — zero sweetness, zero fruit, zero candy. Just clean vapor. Available across three devices, suggesting consistent demand for a no-flavor option.
Clear / Clear
Both chambers unflavored — double-clear for vapers who want the UT Bar Pro 50K hardware without any flavor at all.
Naked / Spring Water
Similar to Clear/Clear but with a "spring water" theme on one side. Essentially unflavored with perhaps a barely-there mineral quality.
Sour Mango Pineapple
Sour-coated tropical duo — mango's nectar sweetness and pineapple's acidic brightness wrapped in a sour candy shell. The sour element prevents Flum's typical sugar saturation from overwhelming.

Frequently Asked Questions
What are the best Flum vape flavors?
Mango Ice scores highest at 71/100, followed by Watermelon Ice, Grape Ice, and Peach Ice (all 70/100). For candy lovers, Gummy Bear (69/100) has the highest sweetness score at 86 — the most sugar-intense flavor in our entire Flum catalog. See our full rankings above.
What does Flum Gummy Bear taste like?
Haribo Gold-Bear in vapor form. Pure candy-shop sweetness at 86/100 with a gelatin note and citric-acid whisper in the mid-draw. Zero cooling, long aftertaste at 70/100 that sticks like actual gummy candy. The highest-sweetness Flum flavor and also the highest Authenticity score (76) — Flum nailed the gummy target.
Flum vs RAZ — which has better flavors?
RAZ averages 70 overall vs Flum's 68, but they suit different preferences. Flum is sweeter (77 vs 72 on Sweetness) with bolder aromas. RAZ has more balanced ice profiles and better candy-sour tension. Pick Flum for maximum sugar; pick RAZ for variety and balance. See our RAZ flavor guide for the full comparison.
Are Flum flavors sweet?
Extremely. Flum averages 77/100 on Sweetness — the highest of any brand in our database. Even ice flavors like Peach Ice (80) and Grape Ice (80) are sugar-dominant. Cool Mint (38) is the only below-average sweetness option. If sugar saturation is what you want, Flum delivers.
What is the strongest menthol Flum flavor?
Cool Mint at 76/100 on Cooling — and it's not close. The next-highest Flum ice flavors (Watermelon Ice and Lemon Ice) tie at 70. Flum deprioritizes cooling in favor of sweetness, so even "ice" flavors feel like a cool breeze rather than a blizzard.
How many flavors does Flum have?
111 unique flavors across 7 devices. The UT Bar Pro 50K has the most at 43 (with dual-flavor pairings), followed by Mello 20K (28) and UT Bar Pro 25K (20). Three legacy devices (Float, Gio, Pebble) remain in the catalog.
What is the Flum UT Bar Pro 50K dual-flavor system?
The UT Bar Pro 50K uses a dual-chamber design that pairs two different flavors in a single pod. You can switch between chambers during use. This creates unique pairings like Cola Ice/Cherry, Tobacco/Gold Tobacco, and Root Soda/Vanilla that no single-chamber device can replicate. It's Flum's primary hardware differentiator.
Does TopVapeFlavors offer free shipping on Flum?
Yes, free shipping on all orders over $50. Orders ship from our City of Industry, CA warehouse. All Flum products are authentic, sourced from verified distributors.
Does Flum have nicotine-free options?
Flum's current lineup is 5% nicotine across all devices. The Clear/unflavored variants deliver nicotine without flavor. For zero-nicotine options, check our Geek Bar guide — the Pulse Zero Nicotine line offers nicotine-free alternatives.
What Flum flavors have no cooling?
Gummy Bear (Cool 12), Sour Gummy (10), Strawberry Banana (10), and Vanilla Ice Cream (8) all have essentially zero cooling. The entire Mello 20K lifestyle series (Blossom, Midnight Barcelona, Milano Adore, etc.) and tobacco flavors also run warm. About 60% of Flum's lineup has no significant cooling component.
