Dark Berry, Soft Cream: Custard Monster Blackberry Reviewed
Overview
Custard Monster Blackberry is the darker of the two single berry custards, rounder and less sharp than Blueberry, and the one to pick if tart fruit is not what you are after.
Flavor Profile: What to Expect
Lively blackberry against soft, delicate custard. Blackberry is a deeper and jammier berry than blueberry, with less acidity and more body, so it sits into the cream rather than cutting across it. The custard base is smooth rather than eggy and carries the fruit without burying it.
The result is the most integrated bottle in the range. Where Blueberry keeps fruit and cream as two distinct things, this blends them into one. Whether that is better is a matter of taste rather than quality.
Who This Is For
You will get on with it if: you want a berry custard that reads as a single dessert rather than fruit sitting on cream. It is the middle ground of the range: richer than Blueberry, lighter than Banana or Butterscotch.
You should probably skip it if: you need a sharp edge to keep a dessert interesting over a long day. Blackberry has less acidity than Blueberry, so it fatigues the palate sooner. Blueberry is the tarter route to the same idea.
One thing worth knowing: Dark berries mute faster than pale ones when a coil starts to age. If this bottle goes flat after a few days, the coil is the likeliest cause rather than the liquid.
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 |
Blackberry is more forgiving at low power than most of this range, because the fruit is jammy enough to read clearly even when the cream is barely warmed. If you are running a mouth-to-lung pod at the bottom of its range, this is a better pick than the plainer custards.
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. It sits mid-range for a custard on coil life, heavier than Blueberry and lighter than Banana or Butterscotch. 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 Blueberry is the tarter sibling, and the obvious second bottle if you want variation inside the same idea.
Frozen Fruit Monster Black Cherry Ice is a cold dark fruit for the other device, which pairs better with this than a citrus would.
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 descriptions place this as the softer and darker of the two single berry custards, using words like delicate and lively for the fruit. The pairing against Blueberry is near universal.
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 Blackberry vs. the Alternatives
The obvious comparison is Jam Monster Blackberry, the same berry spread over buttered toast rather than folded through custard. The jam version is the sweeter and more bready of the two, and the toast gives it a savoury edge this does not have. If you liked the Jam Monster but wanted something smoother, this is that bottle.
Inside the range, Blueberry is the sharper alternative and Mixed Berry folds both in with strawberry.
Final Thoughts
Custard Monster Blackberry is the most seamlessly blended bottle in the range, and the one to choose if you would rather taste one dessert than fruit on top of cream.
Both formats sit on the same page, so you can pick the bottle that matches your device rather than buying twice. Shop Custard Monster Blackberry 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 Blackberry is lively blackberry against soft, delicate custard. The custard base is smooth rather than eggy, and it carries the blackberry 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.
Blackberry is the darker of the two single berry custards, rounder and less sharp than Blueberry. Mixed Berry folds several berries over the same base, and Strawberry is the lightest of the fruit options. Vanilla and Butterscotch are the two bottles in the range with no fruit at all.
Custard Monster Blackberry 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 Blackberry 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 Blackberry 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 Blackberry 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 Blackberry 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 Blackberry 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 Blackberry 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 Blackberry 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 Blackberry out of reach of children and pets.
