Heisenberg e-liquid: which format wins?

One name, one blue label, five products that are not interchangeable. The Heisenberg e-liquid made by Vampire Vape exists as a 10 ml, as a nic salt, as a large shortfill, as a 30 ml concentrate and as a longfill. Retail listings do little more than name the references. This comparison sets them against each other on what genuinely changes from format to format: the base ratio, the yield, and what ends up in your tank.

Heisenberg e-liquid: which format to take for which use

To taste the recipe, or to vape it with nicotine and no preparation, the 10 ml is the only format that covers both. It is also the legal ceiling here, since nicotine containing bottles are capped at 10 ml and 20 mg/ml.

For regular sub-ohm use, the Koncept shortfill takes the lead on volume. It arrives nicotine free with room for shots, which is the standard British answer to the bottle size cap rather than a brand decision.

For anyone vaping this profile all year, the 30 ml concentrate is by far the most productive reference in the range, on condition that you accept the mixing and the steeping wait.

Where the range comes from and what is in the bottle

Vampire Vape is a British manufacturer, and the composition of Heisenberg is officially kept secret by the brand. That is unusual enough to be worth saying plainly rather than filling the gap with invention.

What the brand and its retailers do describe converges. Vampire Vape presents it as a cool blue fruit flavour with icy menthol and subtle aniseed notes over a sweet mixed berry base. Electric Tobacconist describes the same blend of mixed fruit, berries, aniseed and menthol.

That profile is constant across every format. What changes is the medium it is diluted in, and that is exactly where a comparison earns its place. The 10 ml is quoted at 50:50 VG/PG. The house DIY guidance points mixers towards 70VG/30PG. Two bottles of the same recipe, two different vapes.

The five references, one by one

The 10 ml is the historic format, sold across a spread of strengths from 0 mg up to the 20 mg/ml ceiling, on a balanced 50:50 base. It suits a pod or a mouth to lung tank and needs nothing done to it.

The nic salt version sits alongside it in the same 10 ml bottle. It is the same flavour on a different nicotine chemistry, and British retailers list it as a separate line rather than a variant, so check the label rather than the name.

The Koncept shortfill is the large ready to vape format, sold nicotine free in a 100 ml bottle. Two 18 mg shots bring it to 120 ml at roughly 3 mg, which is the arithmetic every UK shop publishes for that size.

The 30 ml concentrate is the DIY route. Vampire Vape states a mixing window of 15 to 20 percent and confirms that all its concentrates are 100 percent PG based, a detail that matters when you are building a high VG mix.

The longfill is the format most people miss. Vampire Vape presents it as a 60 ml bottle holding 20 ml of 50VG/50PG concentrate, so it sits between the shortfill and the concentrate in both effort and yield.

The Heisenberg e-liquid comparison table

The data below reproduces what the manufacturer and British retailers state. No prices appear: they vary too much between shops to serve as a stable point of comparison.

Criterion	10 ml	Nic salt 10 ml	Koncept shortfill	Concentrate 30 ml	Longfill
Ready to vape	Yes	Yes	Yes, add shots	No	No
Stated base	50:50	50:50	High VG	100 percent PG	50VG/50PG
Nicotine	0 to 20 mg/ml	0 to 20 mg/ml	None, add shots	None	None
Preparation	None	None	Add two shots	Dilute at 15 to 20 percent	Top up the bottle
Wait before use	None	None	None	5 to 7 days	Short
Final volume	10 ml	10 ml	120 ml once shot	150 to 200 ml	60 ml
Target hardware	Pod, MTL	Pod	Sub-ohm	Your choice	Your choice

The yield line deserves a stop. At 20 percent a 30 ml concentrate gives 150 ml of finished liquid, and at 15 percent it gives 200 ml. Vampire Vape quotes 200 to 250 ml for a 30 ml bottle across its concentrate range, so treat the lower end of the mixing window as the one that matches the brand’s own headline figure.

What the change of base does to the taste

Menthol is the note most sensitive to the ratio, because coolness travels better through a base rich in propylene glycol. A Heisenberg e-liquid at 50:50 therefore arrives sharper at the back of the throat than the same recipe built at 70/30.

The reverse is equally reliable. A high VG mix thickens the berry and rounds the aniseed off. Plenty of vapers describe the large format as less aggressive, which is not a manufacturing fault but a direct consequence of the base.

Add to that the effect of the nic shots. A shot has its own ratio and it rewrites the one printed on the shortfill, a mechanism our head to head on the PG VG ratio works through with the arithmetic laid out.

The brand’s own DIY guidance closes the loop. It recommends 70VG/30PG for the Heisenberg concentrate, with an optional cooling agent at 0.5 to 1 percent and five to seven days of steeping, which tells you the makers themselves expect mixers to rebuild the coolness the thicker base absorbs.

Verdict: the format that wins by profile

Three uses, three different winners. The ranking changes completely with what you are after, which is precisely why a single verdict would mean nothing here.

Discovering the recipe or vaping on the move with nicotine: the 10 ml wins. It is the only route to a chosen strength with no handling, and its balanced base delivers the coolness the range built its reputation on.

Daily sub-ohm use: the Koncept shortfill wins. At equal finished volume it spares you the mixing session, and two shots is the whole of the preparation.

Steady consumption with the yield in mind: the concentrate wins by a distance, with 150 to 200 ml from one bottle and the freedom to pick your own base. The price is the steeping wait, and that part cannot be compressed.

Frequently asked questions

Does Heisenberg exist as a nic salt?

Yes, British retailers list a Vampire Vape Heisenberg nic salt in 10 ml. Availability varies by shop and by period, so check the explicit mention on the product page rather than trusting the flavour name alone.

Can I mix the concentrate above 20 percent?

Nothing forbids it, but past the stated window the aniseed takes over and the balance goes. Testing on 10 ml before building a large batch avoids wasting a whole bottle.

Why does the colour vary between two bottles?

Fruit recipes darken naturally with air and light, and the speed depends on the production date and the storage. A difference in shade between two bottles does not on its own indicate a fault.

Is the five to seven day steep compulsory?

It is what the brand recommends so the notes can bind. Vaped immediately the mix is usable but unbalanced, with the menthol dominant and the fruit still in the background.

How long does an opened concentrate keep?

A concentrate keeps considerably longer than a finished liquid, provided it is closed and kept away from light. A bottle open for more than a year may have lost intensity without being spoiled.

Choosing your reference with your eyes open

The range gives one name to five products whose bases diverge sharply. A vaper who finds their Heisenberg e-liquid flat has often changed format without changing expectation, when the move from a 50:50 to a high VG mix is enough on its own to explain the gap.

Decide the medium first and the strength second. That rule holds across the whole range, and more generally for any recipe sold in several formats, whether it is a menthol like this one or the dessert profiles we compare in our head to head on caramel e-liquid. The same logic applies to the tropical bottles covered in our piece on dragon fruit e-liquid.
