Tart Blueberry on a Cream Base: Custard Monster Blueberry Reviewed
Overview
Custard Monster Blueberry is the tarter of the two single berry custards in the range, which makes it the easiest of the seven to stay on for a whole day.
Flavor Profile: What to Expect
Juicy, slightly tart blueberry with velvety custard. The tartness is the point. Blueberry has enough acidity to cut through a cream base, and that acidity is what stops the bottle turning into undifferentiated sweetness by the third tank. The custard is smooth rather than eggy and carries the fruit without burying it.
The exhale is rounder and heavier than a straight fruit e-liquid, but noticeably lighter than Butterscotch or Banana. Of the seven, this is the one that behaves most like a fruit bottle while still reading as a dessert.
Who This Is For
You will get on with it if: you like the idea of a dessert but find most custards too heavy to live with. The tart edge does the work that cooling does in an iced fruit, resetting the palate without adding menthol. It is the best all-day candidate in the range.
You should probably skip it if: you want a rich dessert. This is the least indulgent of the seven, and if you came looking for something that tastes like pudding, Banana or Butterscotch are the bottles to look at.
One thing worth knowing: Blueberry tolerates a little more power than the plainer custards, because the fruit survives heat better than the cream does. If you normally find custards too soft at your usual wattage, this is the one to try before turning anything down.
VG/PG Ratio and Bottle Size
The 100mL freebase bottle is mixed at 75VG/25PG. That ratio favours vapour production and a softer throat hit, which suits sub-ohm tanks, box mods and coils rated under 1.0 ohm. The thicker mix wicks slowly, so give a fresh coil a minute to saturate before the first pull.
The 30mL salt nicotine bottle is mixed at 50VG/50PG. The balanced ratio is thinner, so it feeds small pod coils without starving them, and the extra PG carries the custard base more directly than a high-VG mix does.
Which Nicotine Strength to Pick
| Format | Strengths | Suits |
|---|---|---|
| 100mL freebase, 75VG/25PG | 3mg, 6mg | Sub-ohm tanks and pod mods. 6mg for a tighter draw, 3mg at higher power |
| 30mL salt nicotine, 50VG/50PG | 24mg, 48mg | Pods and low-wattage devices. 24mg is where most people land, 48mg for heavier prior use |
The more vapour your device makes per puff, the lower the strength you want. Putting 48mg salt through a sub-ohm tank would be unpleasant and wasteful, and 3mg freebase in a small pod leaves most people puffing constantly and still unsatisfied.

The Setup That Suits It Best
Match the format to the hardware. This is the single most common mistake made with a 100mL bottle.
For the 30mL salt version (50VG/50PG): a mouth-to-lung pod with a coil around 1.0 to 1.2 ohm. The 50/50 mix wicks fast enough for small coils, and the tighter draw concentrates the custard.
| Device | Price | Why it fits |
|---|---|---|
| Black Note Pod System | $9.99 | Our own refillable, built around 50/50 liquids |
| Uwell Caliburn G3 Pro | $27.99 | Adjustable airflow, forgiving with sweetened liquid |
| Vaporesso XROS 6 Mini | $24.99 | Small, consistent, good for all-day carry |
| OXVA Xlim Go | $9.99 | The least expensive sensible way to try the salt bottle |
For the 100mL freebase version (75VG/25PG): anything sub-ohm. A restricted direct-lung coil around 0.6 ohm is the sweet spot for a custard, giving you vapour without cooking the cream.
| Device | Price | Why it fits |
|---|---|---|
| Vaporesso Luxe XR Max 2 | $38.99 | Pod mod that handles 75VG without a full tank setup |
| SMOK Novo 6 40W | $28.99 | Enough power for high-VG, still pocketable |
| Geekvape Aegis Solo 3 | $62.99 | Proper sub-ohm tank, adjustable airflow, best flavour of the three |
Dialling It In: Wattage, Airflow and Priming
Every coil has its range printed on it. Treat that as a starting point rather than a target.
| Coil resistance | Starting wattage | Draw |
|---|---|---|
| 1.2 ohm | 8 to 14W | Mouth to lung |
| 1.0 ohm | 10 to 16W | Mouth to lung |
| 0.8 ohm | 12 to 20W | Loose mouth to lung |
| 0.6 ohm | 15 to 25W | Restricted direct lung |
| 0.4 ohm | 20 to 35W | Direct lung |
This one has the widest usable window in the range. The blueberry stays legible a few watts past the point where a plain vanilla would flatten, which is why it suits a sub-ohm setup better than most custards. Still climb gradually, and back off when the cream disappears behind the fruit rather than the other way around.
Close the airflow down further than you would for a fruit bottle. A tighter draw concentrates the cream; wide open airflow spreads it thin and the custard starts reading as generic sweetness.
Prime a new coil properly: wet the exposed cotton, fill, then leave it five to ten minutes before the first pull. At 75VG the liquid moves slowly, and not waiting is the most common way to ruin a coil on day one.
Coil Life with a Custard
Custards are the hardest e-liquid category on coils. Sweeteners caramelise on hot wire and the cream base leaves residue of its own, so both mechanisms work against you at once. Blueberry sits at the lighter end for a custard, though it is still a sweetened dessert and heavier on coils than any fruit bottle. Coils darkening within a few days of regular use is this category behaving normally rather than a fault with the liquid or the hardware.
Three things genuinely help: run at the lower end of your coil’s range, avoid chain pulls that let the wick run dry, and rinse a pod between refills when switching flavours. Mesh coils outlast round wire here because the heat spreads across a wider surface.
If coil cost is the thing that bothers you, that is a real argument for an unsweetened blend rather than something to work around. Black Note Special Blend and Special Blend 3.0 are naturally extracted tobacco e-liquids made without added sweeteners for exactly this reason.
Flavor Pairing Suggestions
Custard Monster Blackberry is the darker and softer sibling, worth having alongside this if you like the berry and custard idea but want variation.
Jam Monster Blueberry is the same fruit on toast rather than custard, which is a genuinely different bottle despite the shared berry.
A practical note on rotation: keep the custard in one device and anything sharp or cold in another. Cream residue carries over into the next fill more stubbornly than fruit does, and a custard ghost underneath a menthol pleases nobody.
How This Flavor Is Usually Described
Retailer copy consistently calls this the tart one, and pairs it with Blackberry as the two single berry options. Velvety is the word that recurs for the base.
Black Note has not carried this flavor before, so we have no customer reviews of our own yet. Once ratings appear on the product page, read those rather than this section.
Comparison: Custard Monster Blueberry vs. the Alternatives
The closest comparison is not inside this range at all. Jam Monster Blueberry uses the same berry over buttered toast instead of custard. The jam version is sweeter and bready; this one is tarter and creamier. If you have tried the Jam Monster and found it too sweet, this is the same fruit with the sugar pulled back.
Within the range, Blackberry is darker and rounder, Strawberry lighter, and Mixed Berry combines all three ideas if you cannot choose.
Final Thoughts
Custard Monster Blueberry is the most liveable bottle in the range. The tart edge keeps it from wearing out, and it takes power better than the plainer custards do.
Both formats sit on the same page, so you can pick the bottle that matches your device rather than buying twice. Shop Custard Monster Blueberry on Black Note. The 100mL freebase is $13.99 in 3mg and 6mg, and the 30mL salt nicotine is $9.99 in 24mg and 48mg.

FAQ’s
Custard Monster Blueberry is juicy, slightly tart blueberry with velvety custard. The custard base is smooth rather than eggy, and it carries the blueberry without burying it. It reads as a dessert flavor, so expect something rounder and heavier on the exhale than a straight fruit e-liquid, and completely different from a tobacco blend.
Blueberry is the tarter of the two single berry custards, with Blackberry sitting darker and softer alongside it. Mixed Berry combines several berries over the same base if you cannot choose between them. For the custard without any fruit, Vanilla and Butterscotch are the two plain options in the range.
Custard Monster Blueberry is available in four strengths across two formats. The 100mL freebase comes in 3mg and 6mg, which suits sub-ohm tanks where each puff delivers more vapor. The 30mL salt nicotine comes in 24mg and 48mg, which suits pod systems where the puff is smaller and you want more nicotine per millilitre.
The freebase version of Custard Monster Blueberry is a 100mL bottle at 75VG/25PG in 3mg and 6mg, made for sub-ohm tanks and box mods. The salt nicotine version is a 30mL bottle at 50VG/50PG in 24mg and 48mg, made for pods and low-wattage devices. Salt nicotine stays smoother at high strength, which is why the pod format carries the bigger numbers.
Match the format to the hardware. The 100mL freebase version of Custard Monster Blueberry is 75VG and works in sub-ohm tanks, box mods and coils rated under 1.0 ohm. The 30mL salt nicotine version is 50VG and wicks properly in pod systems and refillable pods with higher-resistance coils. Putting high-VG freebase into a small pod coil is the usual cause of dry hits.
Both, depending on which version you pick. The 100mL freebase Custard Monster Blueberry at 75VG is a direct lung e-liquid for sub-ohm setups. The 30mL salt nicotine version at 50VG is a mouth to lung e-liquid for pods, which is the tighter draw most people moving away from cigarettes are used to.
Custard Monster Blueberry is 75VG/25PG in the 100mL freebase bottle and 50VG/50PG in the 30mL salt nicotine bottle. The higher VG in the freebase produces thicker vapor and a softer throat hit in a sub-ohm tank. The balanced 50/50 in the salt nicotine version is thinner, so it feeds small pod coils without starving them.
Custard and dessert e-liquids like Custard Monster Blueberry are among the heaviest on coils, because the sweeteners and the creamy base both caramelize under heat. Expect noticeably shorter coil life than on a fruit or tobacco e-liquid, and run lower wattage to slow it down. If coil life matters more to you than the dessert profile, Black Note Special Blend and Special Blend 3.0 are naturally extracted tobacco e-liquids made without added sweeteners.
No. Custard Monster Blueberry is made with non-tobacco derived nicotine, often labelled NTD on the bottle. Monster Vape Labs states that all of its brands, Custard Monster included, are produced with non-tobacco derived nicotine, which is why the product codes carry an NTD marking. The strength on the label behaves the same either way.
Store Custard Monster Blueberry upright in a cool, dark place, away from sunlight and heat, which matters more for a custard than for a fruit blend because the cream notes dull faster when warm. Keep the cap closed between refills, and keep Custard Monster Blueberry out of reach of children and pets.
