Killer Kustard is referred to as the "gold standard" for vanilla custard vape juices because it has a simple structure with no unnecessary complexity and provides excellent sub-ohm performance with amazing amounts of vapor as a result of its high VG concentration.
Alert: Before we embark, we request minors and non-puffers to keep off! Nicotine is addictive and harmful.
This review of Killer Kustard 
breaks down how it's made, the VG/PG ratios, nicotine levels and how coil type might influence overall performance. Plus, how well each juice works with various devices to see if they have a competitive edge going forward into 2026.
Vapetasia Killer Kustard Flavor Analysis
In contrast to other dessert blends, which consist of more than one flavor, Killer Kustard has been developed with a very defined three-layer structure of custard.
Top Note:
The first part of the flavoring, which is called the top note, is vanilla concentrate. The vanilla characteristics are smooth with mild warmth, and there are no harsh or overly pronounced artificial vanilla characteristics. Instead, the vanilla characteristics are more rounded and eggy/creamy like a custard base.
Mid-Body:
The mid-body character of Killer Kustard has a very thick, heavy, and saturated feel due to the custard base's thick viscosity in vapor form when vaped at higher wattages. This contributes to the mouthfeel of Killer Kustard being heavy, not light and airy sweetness.
Finish:
The finish of Killer Kustard contributes to a level of sweetness not as high as candy but still distinctively sweet. The consistency of the overall flavor profile for Killer Kustard is stable and not excessively flat over time.
Killer Kustard Vape Juice VG/PG
Killer Kustard has a VG content of around 70% and PG content of about 30%.
- Output of vapor
- Produces a good volume of vapour with dense clouds of vapor.
- Keeps saturation fairly constant when use of higher wattages.
- Works well between 55–85 watts.
Throat hit
Being high in VG means Killer Kustard Vape Juice will feel smooth on the inhale (throat hit) because of the viscous nature of the VG.
General observation for throat hit:
- 3mg will feel incredibly smooth when using sub-ohm tanks.
- 6mg will provide some throat hit, but nothing harsh.
- 12mg may be too harsh when used over 85 watts of power, so it's best used on devices that run moderate power.
VG is thicker than PG, and therefore wicks less quickly; use mesh coils or coils with wide-wicking slots to get the most out of the VG in Killer Kustard.
Coil Longevity in Killer Kustard Flavor
Dessert-flavored e-liquids usually have sugary additives which make the coils burn faster. Killer Kustard by Vapetasia is moderate to high in sweetness.
Observed Coil Behavior
Obviously, with increased wattage, my mesh coils will last about 5-10 days depending on how often they are being vaped.
- As my cotton has become darker, I have noticed it occurs slowly as opposed to quickly.
- The taste of my e-liquid will degrade slowly as opposed to immediately.
For longest life from your coils:
- Always thoroughly prime your coils.
- Avoid chain vaping at maximum wattage for prolonged periods.
While all coils do wear down, the degree of wear is similar to that of all custardy flavors with high VG (Vegetable Glycerin).
FAQs
1. What is the Killer Kustard Vapetasia VG level?
The VG ratio in Killer Kustard is high enough so that you can use a sub ohm device. The high VG, as well as not being as harsh on your throat as higher PG e-liquids, also allows for less irritation while vaping.
2. Are there multiple Killer Kustard nicotine strengths?
Killer Kustard is offered in 4 different nic levels, 0mg, 3mg, 6mg and 12mg. The 3mg level is probably best used in a higher wattage sub-ohm setup. The 6mg and 12mg would lend themselves to lower wattage devices.
3. Does killer Kustard burn up your coils quickly?
Killer Kustard flavor has a moderate amount of sweetener which may burn out your coils much quicker than other e-liquids over time. Try vaping it at recommended wattage levels and properly prime each coil prior to use, the performance will diminish over time not all at once.
4. How long will Killer Kustard blueberry by Vapetasia 100ml last?
If you are a moderate user then a sub-ohm setup for vaping between 60 Watts and 80 Watts will finish in 1-2 weeks.
5. Is Killer Kustard nicotine strength too sweet?
Killer Kustard has a very noticeable but controlled sweetness that is typical to dessert e-liquids, leaning more towards a creamy custard-like flavour than candy-like flavor making it quite balanced for long term, every day vaping.
6. Where is Killer Kustard made?
Killer Kustard is made in the USA under the management of Vapetasia because it is manufactured in the USA it will be compliant with all regulatory requirements and will have consistent manufacturing quality standards.
The Bottom Line
Killer Kustard by Vapetasia provides optimal sub-ohm performance and vapor production, and does not rely on complex layering or trendy flavor profiles to achieve its success. The 70VG/30PG e-liquid is built for dense clouds of vapor and smooth inhalation, with the nicotine saturation (0mg, 3mg, 6mg, or 12mg) remaining stable and predictable in throat hit intensity, while maintaining the vanilla custard flavor through all wattage settings on most sub-ohm devices.
The overall stability of the vanilla custard flavor maintains the same taste even after extended use, and there is very little loss of flavor due to wattage spikes when used at the recommended wattage range. Coil wear will occur on a gradual basis, rather than aggressively, as a result of the sweetener in the e-liquid; provided that the coil is regularly maintained.
